THE MENTAL HEALTH TOLL OF COVID-19

Flu vaccine time is always a high-stress period for pharmacists, but this year it’s accompanied by the quadruple whammy of super-charged vaccine promotion campaigns from public health; first-time (but limited) pharmacy availability of the high-dose flu vaccine for seniors; sporadic, phased-in delivery of vaccine supplies; and the new reality of social distancing and PPE requirements. No wonder the comments on CanadianHealthcareNetwork and ‘pharmacy Twitter’ are flooded with pharmacists venting about their stress levels right now. Here’s a sampling of the pharmacists tweets I’ve seen this week: “Every year I say this is going to be the flu season that breaks me. This year I really mean it.” “What’s the best antidepressant to cope with dreaming about flu shots, parenting without a single break for 210+ days, stressed about staff, coping with grieving husband?” “As someone who is within 2 metres of hundreds of people a day, my anxiety keeps me up at night. I always worry that I am exposing the public to COVID.” Pharmacists, we need you to stay well. Venting online can be healthy, but if you find that you can no longer adjust your own oxygen mask, there are some excellent, confidential resources especially for healthcare workers. (www.camh.ca/en/health-info/ mental-health-and-covid-19/information-for-professionals.) Please don’t wait until you can’t breathe.

I’m desperately searching for good news right now, without much luck. Total Canadian cases of COVID-19 topped 218,000 this month, Halloween is cancelled and there is snow in the forecast. My social media feeds are dominated by friends sharing the difficulties they’re having dealing with the toll of this seemingly endless pandemic. Parents are exhausted from juggling work with their restless children’s hybrid in-class and at-home schooling. Many are also monitoring the physical and mental health of elderly parents— while staying away to keep them safe. Folks are suffering from lack of human contact. The laid-off are struggling to survive; entrepreneurs who have had to shutter their businesses in hospitality or the arts are watching their life’s work evaporate. Those who have kept their jobs have seen workloads surge, with little downtime in which to recharge their batteries and acknowledge what’s happening in the world around us. But none have paid as high a toll as healthcare workers. Pharmacists were thrust into crisis mode eight months ago and after a brief semi-reprieve this summer, you’ve had to run right back onto the battlefield; this time to arm Canadians against the flu. (Not that many pharmacists have actually had a break. In Alberta and Ontario, the short-lived downturn in COVID-19 cases in late summer ushered in the launch of asymptomatic testing in some community pharmacies.)

Pharmacists

More than 42,000 pharmacists are currently practising in Canada in a range of environments. That represents an enormous volume of expertise and experience that could be tapped into to help each other solve everyday problems. We thought it would be a good idea to mine that wealth of knowledge to help each other solve some common everyday problems. In each issue, we’ll share pharmacists’ tips and ideas for making life just a little easier. LAST MONTH WE ASKED:

What’s a simple thing you do in your pharmacy to boost staff morale?

“Sunday mornings before we open, I make waffles for the staff. Strawberries, whip cream, and syrup. A simple task, but it starts the day and week off right.” —Steve Bond, ON “Gratitude. Offer your staff praise and thanks. A little gesture goes a long way.” —Brittany Faubert, Sarnia, ON

“I keep a roll of gold star stickers handy and look for reasons to give them away to thank our teammates for their work/ kindness/great ideas/etc. It’s a little juvenile, but I have yet to meet someone who refuses to accept one! It’s also a little reminder to myself to stay positive and focus on the good things being accomplished in our department, big or small.” —Amanda Holgate, Abbotsford, BC

“At our pharmacy, recognition of going above-and-beyond, for learning new tasks, recognition of hard work on a difficult or challenging day, and showing initiative is key. Settling into the new protocols due to the pandemic, and especially now with it being flu season, our team is continually having to adapt to new and changing procedures, helping to educate the public about these changes, and still provide patientcentered care. This deserves recognition, and we make a point to let our team know we see their efforts and appreciate what they do every day. I could not do my job without the whole team, and I let them know that.” —Neemet McDowell, Duncan, BC

regularly rather than big things infrequently.” —Kristy Pelke, Tavistock, ON

birthdays with order-in lunches of pizza and chicken or Chinese food.” —Cathy Savage, Winkler, MB “Pizza lunches.” —Marlene Shehata, Ottawa, ON

“We got a BINGO card and a word is announced every day until someone gets it. The winner gets a gift card. It is fun!!!” —Azmina Premji, Ottawa, ON

2020 has been a year like no other. As we head into a new year, what’s your best tip for a quick mental break when things are stressful?

“We start off every morning with a morning huddle. It’s a time where we can discuss things that are happening that day, but it’s also a time to socialize. One staff member tells jokes so we all start the day off with a laugh. We also take turns bringing in treats or doing a coffee or tea run. We try to do little things

Vascepa® (icosapent ethyl) is indicated to reduce the risk of cardiovascular events (cardiovascular death, non-fatal myocardial infarction, non-fatal stroke, coronary revascularization or hospitalization for unstable angina) in statin-treated patients with elevated triglycerides, who are at high risk of cardiovascular events due to: established cardiovascular disease, or diabetes, and at least one other cardiovascular risk factor Clinical use: Not indicated for pediatric use. Use in geriatrics is not associated with differences in safety or effectiveness, but greater sensitivity of some older individuals cannot be ruled out. Relevant warnings and precautions: • Not recommended in combination with or substituted for other products that contain omega-3 fatty acids • Increased incidence of bleeding • Caution in patients with known hypersensitivity to fish and/or shellfish • Periodic monitoring of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels in patients with hepatic impairment is recommended during therapy with Vascepa® • Fertility • Not recommended in pregnancy and nursing For more information: Please consult the Vascepa® Product Monograph at https://health-products.canada.ca/dpd-bdpp/index-eng.jsp for important information relating to adverse reactions, drug interactions, and dosing/

administration information which have not been discussed in this piece. The Product Monograph is also available by calling HLS Therapeutics Inc. at 1-833-266-3423. * 8,179 statin-treated adult patients with elevated serum triglyceride levels (≥1.5 mmol/L to <5.6 mmol/L) who were also at high risk for atherothrombotic events. Patients either had established CVD or were at high risk for CVD and were randomized to either Vascepa® or placebo. Patients with established cardiovascular disease were at least 45 years of age and had a documented history of coronary artery disease, cerebrovascular or carotid disease, or peripheral artery disease. Patients with other risk factors for cardiovascular disease were at least 50 years of age and had diabetes and at least one additional major cardiovascular risk factor. 5-point MACE was defined as time to first occurrence of cardiovascular death, myocardial infarction, stroke, hospitalization for unstable angina, or coronary revascularization. Most patients at baseline were taking at least one other cardiovascular medication including anti-hypertensives (95%), anti-platelet agents (79.4%), beta blockers (70.7%), angiotensin-converting enzyme (ACE) inhibitors (51.9%), and angiotensin receptor blockers (ARB) (27.0%), with 77.5% taking either an ACE inhibitor or ARB. At baseline, while on stable background lipid-lowering therapy, the median LDL-C was 1.9 mmol/L. † Incidence rates of CV events per 100 patient years (Vascepa® vs. placebo): cardiovascular death, 1.0 vs. 1.2; non-fatal myocardial infarction, 1.4 vs. 2.0; non-fatal stroke, 0.5 vs. 0.7. ‡ CV death includes adjudicated cardiovascular deaths and deaths of undetermined causality. § Comparative clinical significance has not been established.

A review of new launches, new indications, new dosage forms and Health Canada advisories

NEW PRODUCTS

Emerade autoinjector: for treatment of anaphylaxis epinephrine 0.15 mg (approved, but not being marketed initially), 0.3 mg and 0.5 mg solution for injection in prefilled pen (autoinjector), Bausch Health.

INDICATIONS Emergency treatment of

anaphylactic reactions in patients who are at increased risk for anaphylaxis, including individuals with a history of anaphylactic reactions. ACTION Alpha adrenergic receptor stimulation by epinephrine counters the vasodilation and high vascular permeability that occurs during an anaphylactic reaction and which can lead to loss of intravascular fluid volume and hypotension. Beta-adrenergic receptor stimulation by epinephrine causes bronchial smooth muscle relaxation, which helps to alleviate bronchospasm, wheezing and dyspnea that may occur during anaphylaxis. Epinephrine also helps to relieve pruritus, urticaria and angioedema, and may be effective in relieving gastrointestinal and genitourinary symptoms of anaphylaxis because of its relaxant effects on the smooth muscle of the stomach, intestine and urinary bladder. DOSAGE The effective dose usually ranges from 0.005–0.01 mg/kg bodyweight. Children 15–30 kg: usual dose is 0.15 mg. Children > 30 kg: usual dose is 0.3 mg. Adolescents > 30 kg: follow adult dosage recommendations. Adults < 60 kg: recommended dose is 0.3 mg. Adults > 60 kg: recommended dose is 0.3–0.5 mg depending on clinical judgement. Administer an initial dose as soon as symptoms of anaphylaxis are recognized. If there is no clinical improvement or if deterioration occurs,

a second dose may be administered 5–15 minutes after the first injection. Ensure all individuals receiving emergency epinephrine are immediately transported to hospital (ideally by ambulance) for evaluation and observation even if symptoms appear to be improving. Patients/caregivers should be informed about the possibility of biphasic anaphylaxis which is characterized by initial resolution of symptoms followed by symptom recurrence a few hours later. ADMINISTRATION Give intramuscularly (can be self-administered) into the anterolateral aspect of the thigh, through clothing if necessary. Do not inject into the buttock. Press autoinjector gently against the outer side of the thigh; this will trigger the injection. A click can be heard when the injection goes into the muscle. Hold the autoinjector against the thigh for about five seconds. Lightly massage the injection site afterwards. ADVERSE EFFECTS MOST COMMON: Moderate anxiety, feelings of overstimulation, apprehensiveness, restlessness, tremor, weakness, shakiness, dizziness, sweating, tachycardia, palpitations, pallor, nausea and vomiting, headache, respiratory difficulties; symptoms usually subside quickly, especially with rest. MOST SERIOUS: Rare cases of serious skin and soft tissue infections, including necrotizing fasciitis and myonecrosis caused by Clostridia, have been reported at the injection site. Cases of gas gangrene have occurred when epinephrine is injected into the buttock. COMMENTS The first epinephrine autoinjector to be available in a 0.5 mg strength.

Administer intramuscularly in the deltoid region of the upper arm or in the higher anterolateral area of the thigh. Lokelma sodium zirconium cyclosilicate powder for oral suspension, AstraZeneca.

EXPANDED INDICATION The drug’s

indication for use as a potassium binder in the treatment of hyperkalemia in adults has been expanded to include patients on chronic hemodialysis. DOSAGE For patients on dialysis, Lokelma should only be dosed on nondialysis days. Recommended starting dose is 5 g once daily on every non-dialysis day. To establish normokalemia (4–5 mmol/L), the dose may be titrated up or down once weekly based on the predialysis serum potassium value after the long inter-dialytic interval (LIDI). Dose can be adjusted weekly in increments of 5–15 g once daily on non-dialysis days, or down to zero (dose interruption) for a few days to reach normokalemia. To maintain normokalemia, monitor pre-dialysis postLIDI serum potassium regularly (e.g., every four or more weeks). Administer orally as a suspension in water. Can be taken with or without food. Lynparza olaparib tablets, AstraZeneca.

NEW INDICATION Monotherapy for

the treatment of adults with deleterious or suspected deleterious germline and/ or somatic BRCA or ATM mutated metastatic castration-resistant prostate cancer (mCRPC) who have progressed 12

following prior treatment with a new hormonal agent. (Also indicated for use in the treatment of breast cancer, ovarian cancer and adenocarcinoma of the pancreas.) DOSAGE Two 150 mg tablets twice daily (600 mg/d). Continue treatment until progression of the underlying disease or unacceptable toxicity occurs. Patients receiving olaparib for mCRPC should also receive a gonadotropin-releasing hormone (GnRH) analog concurrently, or should have had bilateral orchiectomy. Tremfya/Tremfya One-Press guselkumab solution for injection, Janssen.

NEW INDICATION Treatment of adults

with active psoriatic arthritis, used alone or in combination with a conventional disease-modifying antirheumatic drug (e.g., methotrexate). (Originally indicated only for use in the treatment of adults with moderate-to-severe plaque psoriasis.) DOSAGE 100 mg given by subcutaneous (SC) injection at Week 0 and Week 4, followed by 100 mg SC maintenance dosing every eight weeks.

HEALTH CANADA ADVISORIES

Esbriet: risk of liver injury Drug-induced liver injury (DILI), with transient and clinically silent elevations in transaminases, has been commonly reported in patients treated with Esbriet (pirfenidone). In rare cases, DILI has been associated with some fatal outcomes. Healthcare professionals are advised to: perform liver function tests (ALT, AST, bilirubin) before starting pirfenidone treatment, at monthly intervals during the first six months, and every three months thereafter; promptly measure liver function tests in patients who report symptoms that may indicate liver injury (e.g., fatigue, anorexia, right upper abdominal discomfort, dark urine, jaundice); consider discontinuation or dose adjustments if liver enzyme elevations occur; avoid use in patients with severe hepatic impairment or endstage liver disease; use pirfenidone with caution in patients with pre-existing mild to moderate hepatic impairment.

dug Fibristal (ulipristal acetate) from the Canadian market due to rare cases of severe liver injury requiring liver transplantation. A drug recall was also initiated at the retail pharmacy level. Imbruvica: no link with HLH A Health Canada safety review was unable to establish a link between the use of Imbruvica (ibrutinib) and the development of hemophagocytic lymphohistiocytosis (HLH). HLH is a rare life-threatening condition where a large number of immune cells attack and destroy other blood cells. The review was prompted by five international published cases and one Canadian case report. Health Canada will continue to monitor Imbruvica safety.

those with uncontrolled chronic pain.(5) Patient self-report of cannabis use is considered reliable, provided that fear of repercussions is minimized.(4) An effective initial screening question is simply “Have you smoked marijuana or used cannabis in any form in the last six months?”(4) For patients answering “yes,” more in-depth assessment using a validated screening tool, such as the Cannabis Use Disorder Identification Test–Revised (CUDIT-R) (https://bpac.org.nz/BPJ/2010/June/ docs/addiction_CUDIT-R.pdf), may be warranted. Table 1 lists diagnostic criteria for CUD.(3)

THERAPEUTIC ISSUES

CANNABIS USE DISORDER – A GROWING ISSUE Cannabis use is on the rise in Canada. A 2019 survey found 16.8% of Canadians aged 15 or older used cannabis in the past three months and 6% reported daily or near daily use.(1) While many individuals use cannabis only recreationally, approximately 9% of frequent cannabis users will develop cannabis use disorder (CUD).(2) CUD is characterized by clinically significant functional impairment resulting from persistent and prolonged use.(3) Individuals with CUD often display a decline in school or work performance, relationship difficulties and social withdrawal.(3) Risk factors for development of CUD include younger age of first use, rapid progression to frequent use, concurrent use of other psychoactive substances, comorbid psychiatric disorders, stressful life events, peer use of drugs and social isolation.(3) 14

While many individuals use cannabis only recreationally, approximately 9% of frequent cannabis users will develop cannabis use disorder (CUD).

Assessing patients for problematic cannabis use While it is reasonable to screen all individuals for cannabis use, specific attention should be paid to high-risk populations, including adolescents, patients with comorbid psychiatric disorders, patients with other substance misuse (e.g., alcohol, tobacco) and

NOVEMBER 2020 [Vol.7 No.9]

For patients identified as having CUD, brief intervention and referral to treatment is recommended.(4) While the ultimate goal is sustained abstinence from cannabis, a harm reduction approach with realistic goal setting should be taken.(4) First-line treatments are cognitive behavioural therapy and/or motivational enhancement therapy, which are successful in promoting abstinence in up to 50% of patients.(3,4) If lack of availability or financial barriers preclude access to first-line therapies, general addiction counselling or peer support groups (e.g., Marijuana Anonymous) can be recommended.(5) Currently, no medications are indicated for treatment of CUD. A recent systematic review included 26 randomized controlled trials (RCTs) of adolescents or adults with CUD or heavy cannabis use.(6) Included studies evaluated the impact of medication on one or more of the following: abstinence, cannabis use, treatment retention and withdrawal symptoms.(6) Studies also included a wide variety of nonpharmacologic cointerventions.(6) Overall, no benefit was seen on any of the outcomes studied for the following drugs compared to placebo: bupropion, nefazodone (no longer marketed in Canada), vilazodone, escitalopram, fluoxetine, venlafaxine, buspirone, atomoxetine, clozapine, ziprasidone, topiramate or galantamine.(6)

Approach to treatment, role of pharmacotherapy


Evidence was insufficient to determine the impact of lithium, divalproex, oxytocin and progesterone.(6) Medications showing benefit over placebo in at least one outcome of interest were gabapentin, N-acetylcysteine, dronabinol, and an experimental fatty acid amide hydrolase inhibitor.(6) A 12-week RCT of 50 adults found that gabapentin 1200 mg/day significantly reduced cannabis consumption compared to placebo.(7) Gabapentin was also associated with improvement in clinical depression and neurocognitive scores, improved treatment retention and less severe withdrawal symptoms.(7) An eight-week RCT of 116 youth aged 13–21 found that oral N-acetylcysteine 1200 mg/day significantly reduced cannabis consumption compared to placebo, based on negative urine testing (odds ratio: 2.35 (CI, 1.05–5.24); p=0.029).(8) No difference was noted in end-oftreatment abstinence rates.(8) A 12-week RCT in 302 adults found no benefit for N-acetylcysteine compared to placebo.(9) A 12-week RCT of 48 adults found dronabinol (a synthetic cannabinoid, no longer marketed in Canada) provided benefit for cannabis withdrawal symptoms, but abstinence rates were unchanged compared to placebo.(10) Other synthetic cannabinoids, such as nabilone, did not show clear benefit in any of the included studies.(6) Finally, in a four-week RCT of 70 males, those randomized to a fatty acid amide hydrolase inhibitor (thought to increase endocannabinoid activity) had fewer withdrawal symptoms and reduced cannabis use compared to placebo (mean 0.4 vs. 1.27 joints/day, p=0.0003).(11) Despite these positive findings, all studies were significantly limited by small sample sizes, heterogenicity of co-interventions, high drop-out rates, and other methodological flaws. More research is required before pharmacologic therapies can be routinely recommended for CUD.(6)

Pharmacist’s role

As a first point of contact with the healthcare system, pharmacists are ideally positioned to screen patients for problematic cannabis use. Particular attention should be paid to asking youth and other high-risk populations about cannabis use.(4) Similar to a smoking cessation approach, if problematic use

TABLE 1

Diagnostic Criteria for Cannabis Use Disorder(3)

Criteria* A problematic pattern of cannabis use leading to clinically significant impairment or distress, as manifested by at least two of the following, occurring within a 12-month period: • Cannabis often taken in larger amounts or over a longer period than was intended. • A persistent desire or unsuccessful efforts to cut down or control cannabis use. • A great deal of time spent in activities necessary to obtain cannabis, use cannabis, or recover from its effects. • Craving, or a strong desire or urge to use cannabis. • Recurrent cannabis use resulting in a failure to fulfill major role obligations at work, school or home. • Continued cannabis use despite having persistent or recurrent social or interpersonal problems caused or exacerbated by the effects of cannabis. • Important social, occupational or recreational activities are given up or reduced because of cannabis use. • Recurrent cannabis use in situations in which it is physically hazardous. • Cannabis use is continued despite knowledge of having a persistent or recurrent physical or psychological problem that is likely to have been caused or exacerbated by cannabis. • Tolerance, as defined by either of the following: a) A need for markedly increased amounts of cannabis to achieve intoxication or desired effect. b) Markedly diminished effect with continued use of the same amount of cannabis. • Withdrawal, as manifested by either of the following: a) The characteristic withdrawal syndrome for cannabis. b) Cannabis (or a closely related substance) is taken to relieve or avoid withdrawal symptoms. *Severity determined by number of criteria present: Mild: 2–3, Moderate: 4–5, Severe: 6+

is suspected, pharmacists can provide a brief educational intervention and encourage patients to set goals for reducing or stopping use. It is important to educate patients to expect physiological withdrawal symptoms within 24–72 hours of stopping heavy cannabis use. These may consist of irritability, anger, anxiety, depressed mood, insomnia and decreased appetite, and persist for one to two weeks.(3,5) Withdrawal symptoms may be mitigated by gradual reduction of cannabis intake and encouraging patients to adopt a healthy routine including adequate hydration, exercise and limiting caffeine, as well as connecting with a support person or group during the withdrawal period. Patient educational tools and other harm reduction resources are available from the Canadian Public Health Association (https://www.cpha.ca/ harm-reduction-health-promotion-andcannabis-screening-tools).

ADVERSE REACTIONS

ACEIs, ARBs AND COVID-19 Concerns have been raised regarding whether angiotensin-converting enzyme inhibitors (ACEIs) and angiotensinreceptor blockers (ARBs) may increase the susceptibility of patients to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes COVID-19. The putative mechanism for this increased risk suggests that ACEIs and ARBs may cause upregulation of angiotensin-converting enzyme 2 (ACE2), which is presumed to act as a viral receptor for SARS-CoV-2 to gain entry to host cells. However, retrospective cohort studies have not found any association with ACEI/ARB use and likelihood of receiving a positive SARS-CoV-2 test result. In addition, observational studies examining the effect of ACEI/ARB drugs on the risk of COVID-19 outcomes have not shown that these drug classes are associated with more severe COVID-19 disease. A more recent retrospective cohort trial examined whether use of ACEIs/ARBs versus other antihypertensive drugs was associated with COVID-19 diagnosis and worse outcomes in patients with COVID-19. A total of 4,480 confirmed COVID-19 patients from Denmark were included in the analysis. The sample included 895 patients who had used ACEIs/ARBs within the past six months and 3,585 nonusers. In the ACEI/ARB group, 18.1% patients died within 30 days versus 7.3% in the nonuser group. However, this was not shown to be significant after adjustments for age, sex and medical history (adjusted hazard ratio 0.83, 95% confidence interval [CI] 0.67â&#x20AC;&#x201C;1.03). In the analysis for COVID-19 susceptibility among patients with hypertension, ACEI/ARB use did not increase the risk of COVID-19 diagnosis compared with other antihypertensive 16

ADVERSE REACTIONS

SGLT2 INHIBITORS AND RISK OF DIABETES KETOACIDOSIS Sodium-glucose cotransporter 2 (SGLT2) inhibitors, including canagliflozin, dapagliflozin, empagliflozin and ertugliflozin, are used in the management of patients with type 2 diabetes. In patients with type 2 diabetes at high cardiovascular risk, they have also been shown to reduce the risk for myocardial infarction, heart failure, renal failure and cardiovascular mortality. Although these agents are generally well tolerated, a possible increased risk for diabetes ketoacidosis (DKA) has been noted based on spontaneous adverse drug reaction reports. A large, population-based cohort study assessed the risk for DKA in patients prescribed SGLT2 inhibitors compared with dipeptidyl peptidase-4

Using data from seven Canadian provinces and the United Kingdom, 208,757 new users of SGLT2 inhibitors were matched 1:1 to new DPP-4 users. Canagliflozin was used by


Implications for pharmacists

Most patients who develop DKA while on a SGLT2 inhibitor will have a precipitating event, such as dehydration, infection, surgery or change in insulin dose. The US Food and Drug Administration has recently recommended safety labelling changes for SGLT2 inhibitors: canagliflozin, dapagliflozin and empagliflozin should be discontinued three days before scheduled surgery, and ertugliflozin should be stopped at least four days before. Once the patient’s oral intake is back to baseline, the SGLT2 inhibitor may be restarted. REFERENCES

which was about three times that seen with patients receiving DPP-4 inhibitors (0.75 per 1,000 person years). The rate for individual agents was 1.86 per 1,000 person years for dapagliflozin, 2.52 for empagliflozin and 3.58 for canagliflozin.

ABOUT

Symbicort® Turbuhaler®

SAY HELLO TO

SYMBICORT¨ What is Symbicort® Turbuhaler® indicated for? Pr Symbicort® Turbuhaler® (budesonide and formoterol fumarate dihydrate) is indicated for the treatment of asthma in patients 12 years and older with reversible obstructive airways disease.1

Symbicort® 200 Turbuhaler® Anti-Inflammatory Reliever Therapy can be used for the treatment of mild persistent asthma in patients 12 years and older. Symbicort® Turbuhaler® can be used according to three different treatment approaches: A. Symbicort® Turbuhaler® Anti-Inflammatory Reliever Therapy: in patients with mild persistent asthma, Symbicort® 200 Turbuhaler® is taken as needed for relief of asthma symptoms when they occur. Symbicort® Turbuhaler® has not been evaluated in patients whose asthma can be managed by occasional use of a rapid onset, short duration, inhaled beta2-agonist. B. Symbicort® Turbuhaler® Anti-Inflammatory Reliever plus Maintenance Therapy: in patients with moderate or severe asthma, Symbicort® 100 Turbuhaler® or Symbicort® 200 Turbuhaler® are taken both as daily maintenance therapy and as needed for relief of asthma symptoms when they occur. C. Symbicort® Turbuhaler® Maintenance Therapy: in patients with moderate or severe asthma, Symbicort® Turbuhaler® is taken as a fixed-dose daily treatment with a separate short-acting bronchodilator for relief of symptoms when they occur. Once asthma control is achieved and maintained, the patient should be assessed at regular intervals.

What were the results for Symbicort® in some of the key clinical trials? The efficacy of Symbicort® was evalutated in a clinical trial program of the trials below.

SYGMA 1 study – mild persistent asthma patients Symbicort ® 200 Turbuhaler® Anti-Inflammatory Reliever therapy:1,3¶§ vs. terbutaline (terb 0.5 mg prn) demonstrated mean % WCAW 34.4 vs. 31.1% (primary endpoint, p=0.046; [odds ratio, 1.14; 95% CI, 1.00 to 1.30]).¥

Symbicort Turbuhaler Maintenance Therapy • In a study of moderate-to-severe adult and adolescent asthmatics not well-controlled on inhaled glucocorticosteroids alone (≥ 750 mcg ICS daily), Symbicort® Turbuhaler® dosed twice daily (total daily dose 1600/48 mcg) was more effective than budesonide dosed twice daily (total daily dose 1600 mcg) in increasing morning PEF over 12 weeks of treatment (mean difference was 32.9 L/min, p<0.001). Statistically significant improvements were also seen for evening PEF (p<0.001), total asthma symptom score (p=0.005), daytime asthma symptoms (p<0.001), symptom free days (p<0.001), use of rescue medication (p<0.001), rescue free days (p<0.001), asthma control days (p<0.001), time to first mild exacerbation (p=0.003) and FEV1 (p<0.001).1

• Total maximum of 8 inhalations of Symbicort® per day. Not to exceed 6 inhalations on any single occasion. • A persistent increase in the use of Symbicort® 200 Turbuhaler® as needed indicates a deterioration of asthma control and the patient’s condition should be re-evaluated to determine the appropriate treatment. * Symbicort® 100 Turbuhaler® should not be used as Symbicort® Anti-Inflammatory Reliever Therapy.

When was the onset of effect seen with Symbicort® compared to salbutamol? Symbicort® demonstrated rapid onset of effect—as early as 3 minutes —post-administration, similar to salbutamol (FEV1; secondary endpoint)1,2**†

MODERATE OR SEVERE ASTHMA SYMBICORT® 200 TURBOHALER® ANTIINFLAMMATORY RELIEVER PLUS MAINTENANCE THERAPY:

Contraindications: • Hypersensitivity to inhaled lactose Most serious warnings and precautions: Risk of serious asthma-related events – hospitalizations, intubations and death: Use of long-acting beta2-agonists (LABA) as monotherapy (without inhaled corticosteroids [ICS]) may increase the risk of asthma-related death and the risk of asthma-related hospitalizations in pediatric and adolescent patients. These findings are considered a class effect of LABA monotherapy. When LABA are used in fixed-dose combination with ICS, data from large clinical trials do not show a significant increase in the risk of serious asthma-related events (hospitalizations, intubations, death) compared with ICS alone Asthma reliever medication: Inform patients to have reliever medication available at all times. Asthma patients should be clearly instructed to use medication for relief of asthma symptoms (e.g., Symbicort® Turbuhaler®, or salbutamol). Excessive use and use with other LABA products: Do not exceed the recommended Symbicort® Turbuhaler® dose. Cardiovascular effects and fatalities have been reported in association with excessive use of inhaled sympathomimetic drugs. Use in adolescents: Periodic reassessment should be considered as severity of asthma may vary with age. Possible systemic effects, which may occur with any inhaled corticosteroid, include growth retardation in children and adolescents. Physicians should closely

follow the growth of adolescents taking long-term corticosteroids and weigh the benefits of asthma control against the possible risk of growth suppression. Systemic effects of corticosteroids: May occur with any inhaled corticosteroid and include Cushing’s syndrome, Cushingoid features and adrenal suppression, decrease in bone mineral density, cataract and glaucoma. Any inhaled corticosteroid should be titrated to the lowest dose at which effective control is maintained. Possible systemic effects, which may occur with any inhaled corticosteroid, include growth retardation in children and adolescents. Other relevant warnings and precautions: • Maintenance treatment with ICS should not be stopped abruptly, but tapered gradually under supervision • Cardiovascular effects • Candidiasis • Hyperglycemia, hypokalemia • Enhanced effect of corticosteroids on patients with hypothyroidism and cirrhosis • Adrenal insufficiency in patients transferred from systemic steroid • Decreased bone mineral density • In rare cases, systemic eosinophilic conditions • Susceptibility or decreased resistance to infection • Glaucoma, increased intraocular pressure and cataracts • Paradoxical bronchospasm • Potential risk during pregnancy, labour, delivery or nursing • Special caution in patients >65 years of age with concomitant cardiovascular disease • Control of asthma should be monitored

• HPA axis function and hematological status should be assessed periodically For more information: Consult the Product Monograph at azinfo.ca/symbicort/ pm796 for important information regarding adverse reactions, drug interactions and dosing.

5 Tips

PEARLS YOU CAN USE IN YOUR PRACTICE NOW

ENHANCING ADHERENCE TO INHALER THERAPY BY SARA INGRAM, BA, MSc, BSc Pharm, ACPR

W

hether being used to treat asthma or chronic obstructive pulmonary disease (COPD), respiratory inhalers have very high nonadherence rates at 30%–70%.(1) As higher inhaler adherence is associated with positive health outcomes, improved disease control and a reduction in mortality,(2) how can we as pharmacists do better? What are the barriers to adherence, and how can we

1

Are patients on the right inhalers? Assess inhaler therapy in accordance with guideline recommendations, as summarized for asthma (Table 1, online) and COPD (see below). If symptoms are poorly controlled, determine if it is due to poor adherence versus inadequate therapy, prior to adding or adjusting medications.(4) COPD: The stepwise approach to COPD, like asthma, depends on the severity of the disease. As per the 2019 GOLD guidelines,(6) severity is predominantly based on the number of exacerbations and/or hospitalizations. It is categorized into Groups A to D, which range in severity from mild to severe. From an inhaler perspective, we start with a bronchodilator, switch classes if not adequate, then add either a long-acting betaagonist (LABA) or long-acting 20

muscarinic antagonist (LAMA). The next step is to combine a LABA and LAMA, then consider adding an inhaled corticosteroid (ICS) to the LABA. Oral therapy may be considered subsequently.(6) A major recent change in COPD treatment has been the addition of more choices in each inhaler class.

2

Know what’s what in inhaler products and devices on the market Adherence barriers often lie with the devices themselves: cost, technique and use. Manufacturers are now looking to enhance adherence by offering different inhaler formats, better drug deposition, as well as combination and longer-acting formulations. Inhalers can be easily categorized by drug class and indication (Table 2). Engage patients in the decision-making process about inhaler type, as some may NOVEMBER 2020 [Vol.7 No.9]

help patients use their inhaled medications more consistently? Nonadherence can be unintentional or intentional. We should be aware of intentional nonadherence, but it is often more challenging to modify, as change is rarely achieved through the usual approaches. This article provides five tips for improving unintentional nonadherence, as interventions such as simplifying treatment regimens and providing education can have a big impact.(3)

be better suited to them (see attributes in Table 3). Ensure drug coverage whenever possible; an expensive device that isn’t covered is much less likely to be used.

3

Manage expectations Patients need to understand the role of the prescribed medications and how to use them. As pharmacists, we need to know if there are any patient concerns that may preclude use. We have unique opportunities for teaching and interaction, and can assess if the devices are working and appropriate. Assess and identify patient preferences and barriers to treatment: • Do they think it will help, or are they worried about harm? Are there side effect concerns you can put in perspective? • Medication-taking experience: inhalers with low taste or smell may be more

palatable, but less confirmatory that a dose has been taken (e.g., salbutamol metered-dose inhaler vs. dry powder inhaler) • Trusting the inhaler as a medication: unlike oral medications, which have a strong visual confirmation, inhalers require a greater degree of trust in the healthcare provider. Reassure patients that they are taking an effective medication. • Are they angry or upset about their diagnosis? This can be a significant barrier to medication adherence. Active listening and periodic checkins may help.

4

Play the “matching game” Assist patients and physicians in deciding which inhalers are most appropriate for the indication and for the individual. • Ensure patients are on the right step in therapy, and help them select the most convenient inhaler and combination.


• Tailor therapy to patient/ caregiver factors: - Age at onset/current age: young child vs adolescent vs. older adult(2) - Cognitive and dexterity factors - Cultural norms - Who will administer the inhalers? Are they trained/ skilled? Any concerns that may prevent administration? • Use all resources available (demos, apps, YouTube teaching videos, manufacturer resources), to ensure the patient is familiar with how to use the inhaler. • Consider if matching inhalers or distinct ones are preferred. • Streamline or step-down therapy whenever possible.

Use technology and follow up Approaches to teaching and follow-up should be ageappropriate for the person using the inhaler. Parents of young children with asthma will have different needs from the teenager with asthma, as will the older adult with COPD. Identifying your patient and following through can yield significant benefits. In a community setting, make take-home or online resources available. Examples may include website links, YouTube videos, apps, electronic reminders or text messages. Some patients may benefit from additional counselling or support services. At each encounter, assess inhaler technique, provide encouragement and ensure the inhaler is meeting the patient’s needs and expectations; if not, adjust or educate. Pharmacy technicians can help by providing instructions on how to operate medical devices such as inhalers (where jurisdiction permits),(8) identifying patients who may benefit from further assessment by a pharmacist and directing patients to pharmacy resources. Add value with smoking cessation or seasonal allergy resources.

ABOUT

Acne treatment for the face and trunk What is AKLIEF® indicated for? AKLIEF is indicated for the topical treatment of acne vulgaris of the face and/or trunk in patients 12 years of age and older.3 What is the incidence of truncal acne? In an evaluation of 696 patients, it was found that 52% of facial acne patients also had truncal acne. Of the patients that presented in this evaluation with a main complaint of only facial acne, 22.4% also had truncal involvement, which was only identified after a clinical examination of the chest and/or back. The patients that presented with truncal acne vulgaris were also surveyed in this evaluation, and about 3 out of 4 said they were interested in treatment for their truncal acne specifically, whether or not they mentioned truncal involvement as part of their main complaint.4* What is AKLIEF? • AKLIEF is the only prescription topical medication in Canada that is indicated in truncal acne as well as facial acne.1 • Trifarotene is a retinoid-like compound that consists of a terphenyl acid derivative that belongs to a new generation of the pharmacological class of retinoid acid receptor γ (RARγ) (gamma) agonist.3 What is the mechanism of action of AKLIEF?3†‡ • Biochemical and pharmacological profile studies have demonstrated that trifarotene is a potent modulator of cellular differentiation, keratinization and inflammatory processes all of which represent important features in the pathology of acne vulgaris. • Although the exact mode of action of trifarotene is unknown, in primary pharmacology studies, trifarotene has shown a high RAR activity and a very high selectivity for RAR γ (gamma) the receptor subtype present in keratinocytes and recognized to be the most relevant in acne over RARα and RARβ.

Pharmacodynamics AKLIEF produced the same comedolytic effect as other retinoids at a 10x lower dose in the Rhino-mouse model. In addition, trifarotene has also shown anti-inflammatory and depigmenting activities.3† Absorption and elimination Steady state conditions were achieved in both adults and pediatric subjects (12-18 years old) following 2 weeks of topical administration; and no drug accumulation is expected with long-term use. Overall, systemic exposure levels were low and similar between adult and pediatric (12-18 years old) populations. The terminal half-life ranged from 2 to 9 hours in patients receiving a once daily cutaneous application of AKLIEF.3 What was the efficacy of AKLIEF in clinical trials? AKLIEF demonstrated superior efficacy vs vehicle for facial and truncal acne.3§

Patients were assessed to evauate the frequency and severity of truncal acne vulgaris. † Clinical significance is unknown. ‡ The exact mode of action for trifarotene is unknown. § Phase III, double-blind, randomized, vehicle-controlled, 12-week study of 1208 subjects (AKLIEF n=612; vehicle n=596) with moderate facial and truncal acne vulgaris. The primary endpoint was rate of success on the face, as determined by the Investigator’s Global Assessment (IGA) (clear or almost clear and ≥2 grade improvement), and absolute change in facial inflammatory and non-inflammatory counts from baseline to Week 12. The secondary endpoint was rate of success on the trunk, as determined by the Physician’s Global Assessment (PGA) (clear or almost clear and ≥2 grade improvement), and absolute change in truncal inflammatory and non-inflammatory counts from baseline to Week 12. The definitions of severity for the 5-point IGA (face) and PGA (trunk) scales were the same: 0 (clear), 1 (almost clear), 2 (mild), 3 (moderate) and 4 (severe).4


How is AKLIEF administered?3 Apply a small amount of AKLIEF to provide a thin layer to the affected areas of the face and/or trunk once a day, in the evening, on clean and dry skin. • One pump actuation should be enough to cover the face (i.e., forehead, cheeks, nose, and chin). Apply a thin layer to cover the entire affected areas. • Two pump actuations should be enough to cover the upper trunk (i.e., reachable upper back, shoulders and chest). • One additional pump actuation may be used for middle and lower back if acne is present. • Hands should be washed after applying AKLIEF. The use of a moisturizer before and after is recommended as frequently as needed from the initiation of treatment, while allowing sufficient time before and after the application of AKLIEF to allow the skin to dry. • Using too much AKLIEF, or using it more than once a day, may increase the risk of skin irritation. • Avoid using AKLIEF on skin areas with cuts, abrasions, eczema or on sunburned skin.

include application site reactions, such as skin irritation characterized by local cutaneous reactions such as erythema, scaling, dryness, and stinging/burning.3 • Most of these treatment-related adverse reactions are mild to moderate, with few being severe.3 • Maximum severity typically occurred within the first 4 weeks of treatment, and decreased with continued use of the medication 3

COUNSELLING OPPORTUNITY In your patients diagnosed with facial acne, consider asking them if they have any truncal acne as well—their back, shoulders and/or chest. Recommend that your patients avoid skin products that may dry or irritate their skin such as harsh soaps, cleansers, astringents, cosmetics that have strong skin drying effects and products containing high levels of alcohol, spices or limes. Advise your patients to use a non-comedogenic moisturizer (e.g., Cetaphil Moisturizing Lotion or Cream) to help minimize irritation.

Discontinue treatment Discontinue treatment if a severe local inflammatory response is experienced. Reinstitute therapy when the reaction has subsided, initially applying the preparation less frequently (e.g. every other day). Once-daily application may be resumed if it is judged that the patient is able to tolerate the treatment. Frequency of application should be closely monitored by careful observation of the clinical therapeutic response and skin tolerance.3 Are there local cutaneous reactions associated with AKLIEF? Certain side effects, such as erythema, dryness, scaling, burning or pruritus, are associated with the application of all retinoids, and can also be expected with AKLIEF. • Treatment-related adverse reactions typically associated with the use of AKLIEF Clinical use: Safety and effectiveness have not been established in children under 12 years or geriatric patients (≥65year). Contraindications: • Eczema or seborrheic dermatitis • Pregnancy or women planning a pregnancy Most serious warnings and precautions: For external use only, not for ophthalmic use. Pregnancy or planning a pregnancy: Rare reports of birth defects associated with topical retinoids during pregnancy. Women of child-bearing potential should be informed of potential risks and use effective birth control measures. Other relevant warnings and precautions: • Discontinue use if allergic/hypersensitivity reactions occur • Avoid contact with eyes, lips, angles of the nose, mucous

During treatment with AKLIEF, avoid excessive exposure to sunlight, including sunlamps, tanning beds and ultraviolet light. Emphasize the importance of avoiding sun exposure. If exposure to the sun is unavoidable, wear protective clothing over the treated areas and use sunscreen with SPF 15 or higher. What is the tolerability profile of AKLIEF? AKLIEF has a demonstrated safety profile and was generally well tolerated on both the face and trunk.3

RECOGNIZING HS DO YOU RECOGNIZE PATIENTS WITH HIDRADENITIS SUPPURATIVA (HS)?

“People with HS come to the emergency room in severe pain and discomfort requiring assistance with the draining of the boils during a flare-up. It’s not unusual for patients to go home undiagnosed.”

DR. NEIL SHEAR

DR. RALPH GEORGE

Head of Dermatology, Sunnybrook Hospital

Associate Professor, University of Toronto, Division of General Surgery

“HS is a chronic, painful, inflammatory skin disease that affects 1-4% of the general adult population. It is characterized by boils usually occurring where certain sweat glands are located, such as under the breasts, buttocks, and inner thighs.”

NEW

DR. VU KIET TRAN ER physician, University Health Network

“There is currently no cure for HS. Early diagnosis and proper management is important for a patient’s quality of life. The first step for those with HS is to speak to their dermatologist to get an accurate diagnosis.”

North American HS Guidelines NOW AVAILABLE

To learn more about HS from these specialists and the new guidelines, go to www.RecognizingHS.com/PHP

WHEN YOU SEE THESE LESIONS, DO YOU SUSPECT HS? DO YOU ASK ABOUT RECURRENCE?

ASSESSING PATIENTS WITH RECURRENT BOILS Most HS cases can be recognized with high reliability by the presence of 3 main features:1-3 1. Typical lesions: nodules, sinus tracts, abscesses, scarring 2. Typical anatomical location: axilla, groin, genitals, under the breasts, others (perianal, neck, abdomen, buttocks) 3. Relapses and chronicity: ≥2 times per 6 months

Photo compliments of Dr. Marc Bourcier.

Questions to ask your patients with suspected HS:2 1. Have you had outbreaks of boils during the last 6 months? 2. Where were the boils and how many did you have? To confirm an HS diagnosis, please refer your patient to a dermatologist.

CLINICAL FEATURE

TIMING IS EVERYTHING Understanding the optimal duration of antibiotic therapy for common infections BY SUZANNE SINGH, BScPhm, ACPR, PharmD, RPh

A

ntimicrobial resistance is one of the biggest threats to global health, including the health of Canadians.(1,2) Each November, the World Health Organization marks World Antibiotic Awareness Week to increase awareness of antimicrobial resistance. The aim is to encourage best practices among the general public, healthcare professionals and policy makers, to avoid the further emergence and spread of antimicrobial resistance.(2) As pharmacists, we have a professional and societal obligation to act. We are trained to identify drug-therapy problems and offer solutions. I have previously written about how pharmacists working in community practices are well-positioned to act as antibiotic stewards.(3) Iâ&#x20AC;&#x2122;ve suggested that pharmacists can help ensure that antibiotics are prescribed appropriately when needed, and only when needed, via the following five strategies: (1) public education, (2) immunization, (3) minor ailment assessment,

(4) prescribing optimization and (5) effective antibiotic counselling. This article embarks on a deeper dive into one of the components of prescribing optimization—optimizing the duration of antibiotic treatment for common infections in the community.

Excessive duration of therapy: a form of antibiotic overprescribing

Pharmacists should be aware of three categories of antibiotic overprescribing.(3) The first category is using an antibiotic when one is not likely to be beneficial. Most clinicians are familiar with this type of antibiotic overuse. In fact, it has been established in the literature that antibiotics prescriptions are commonly unnecessary in the community. For example, evidence suggests that antibiotics are overprescribed in upper respiratory tract infections, with an estimated 30%–50% of antibiotics prescribed judged to be unnecessary, and elderly patients being most likely to receive a prescription.(4,5) The second category of overprescribing is prescribing a broad-spectrum antibiotic when a narrow-spectrum agent will do. I explain this category of unnecessary antibiotic prescribing using the expression “do not use a cannon to kill a mosquito.” Empirical use of broad-spectrum antibiotics increases, by selection, the prevalence of bacteria resistant to several antibiotics. Finally, the third category of overprescribing, the focus of this article, is prescribing an antibiotic for an excessive period of time. A study of primary care prescribers from the United Kingdom concluded that for most common infections treated in primary care, a substantial proportion of antibiotic prescriptions have durations exceeding those recommended in guidelines.(6) Research conducted by Public Health Ontario (PHO) found that the median duration of antibiotic regimes prescribed by Ontario family physicians was seven to eight days (38%), with less than

25% of prescriptions prescribed for shorter than seven days, and 35% of antibiotic courses prescribed for longer than eight days.(7) PHO also observed considerable variability in prescribed antibiotic duration across family physicians, with greater use of prolonged antibiotic courses associated with later physician career stage, rural location and a large pediatric practice.(7) The reality is that shorter durations of antibiotic treatment courses are often supported by evidence, but not necessarily adopted by prescribers.(8-10) We should not be exposing our patients to excessive antibiotics, and pharmacists can (and should) influence decisions about optimal treatment durations.

Risks of excessive durations of antibiotics: every day matters for every patient

A scan of the literature identifies several studies which highlight that even one extra day of antibiotics can be harmful to patients. One retrospective UK study showed that patients hospitalized for community-acquired pneumonia had a 9% risk of Clostridium difficile per day, with longer durations of antibiotics being a contributing factor.(11) Other studies in hospitalized patients have also demonstrated a relationship between longer duration of antibiotic use and emergence of drug resistance.(12-14) In addition to the collateral ecological damage of antibiotics, such as C. difficile and drug resistance, the other risks of antibiotics are worth a reminder. The spectrum of harm that can result from antibiotics ranges from side effects, such as nausea, vomiting, diarrhea and yeast infections, that may adversely impact a patient’s quality of life, to more serious risks. Some of these risks can be drug or drug-class specific. A few examples of safety concerns include the risk of tendon rupture with fluoroquinolones; the risk of QT prolongation with fluoroquinolone and macrolide drug interactions; and the risk of hyperkalemia with trimethoprim–sulfamethoxazole when used with drugs that also increase potassium, such as angiotensinconverting enzyme inhibitors, angiotensin-II receptor blockers and potassium-sparing diuretics.(3) Evidence suggests that antibiotics are frequently implicated in adverse drug reactions that lead to emergency room visits.(15) The key message is that every extra day counts when it comes to exposing patients to antibiotic harms.

“Guidelinitis” and the lack of standardization in antibiotic treatment durations

Recommended treatment durations for common community infections should be found fairly easily in clinical practice guidelines, right? If one asked where to find the Canadian guidelines for how to treat [insert common community infection here], in truth, the answer to that question may be somewhat complicated and may require successive computer clicks. We have seen other jurisdictions, such as the United Kingdom, tackle the development of national guidelines for common community infections, with a lens of antibiotic stewardship. The UK’s National Institute for Health and Care Excellence (NICE) has produced guidance and quality standards for antibiotic use in the community.(16) Canada seems to lag behind in this regard.(1) In the absence of a “standard place to look” to find Canadian guidelines on community infections, clinicians are challenged to review multiple sources to hunt down answers. The phenomenon of “guidelinitis” has been used in the literature to describe the predicament clinicians may face when there are


multiple guidelines on a single topic, potentially with conflicting and/or faulty recommendations.(17) This is certainly relevant to the discussion around how best practices are determined and possible reasons to explain variations in practice.(17) When recommendations from various sources are not aligned or up to date, clinicians may be left to use their own judgments around best practices for antibiotic prescribing, of which treatment duration is one. Perhaps this may partly explain why practitioners gravitate towards using a default of “7 days” for most antibiotic prescriptions; while simplistic, it might very well be unrealistic to expect busy practitioners to curate the available literature. I, myself, struggle with finding time to critically appraise clinical practice guidelines or look into the primary literature from which guidelines are derived. I access a number of resources when caring for my patients and working with my primary care team to help navigate antibiotic prescribing decisions. These resources include, but are not limited to, guidance from organizations such as the Infectious Diseases Society of America (IDSA), the Public Health Agency of Canada (PHAC), Public Health Ontario (PHO) and various specialist organizations. In Ontario, one notable resource is the Anti-infective Guidelines for Community Acquired Infections (~$30), published by the academic detailing group, MUMS Health.(18) This popular resource is commonly referred to by primary care practitioners simply as “the orange book,” which designates the colour of the book’s cover, although this resource is also available in App format. Similarly, Bugs & Drugs (free online) is likely recognizable to Albertans and beyond, and the Saskatchewan-based academic detailing group of RxFiles has also done some important work on antibiotic stewardship in primary care.(19,20) At a local level, I periodically access resources from my hospital’s antibiotic stewardship program.(21) I would encourage practitioners to familiarize themselves with these available resources so they can be better equipped to support effective antibiotic use.

Antibiotic treatment durations for common infections: a brief guide There can be problems with treating bacterial infections with either too long or too short of a course of antibiotics. Problems with treating for too short a period may include therapeutic failure, relapse and selecting resistance for pathogenic bacteria. Problems with treating for too prolonged a course may include adverse effects, such as C. difficile and developing drug resistance; the risk of patient nonadherence with a longer course of treatment; and an increased financial cost to the patient or healthcare system. I’ve attempted to summarize current recommendations for antibiotic treatment durations for common infections (Table 1) based on my review of the literature.(22-34) This table is essentially “the money shot” for this article! Review it carefully. As a general summary, for acute uncomplicated cystitis, nitrofurantoin is typically administered for five days, trimethoprim–sulfamethoxazole or quinolones for three days, and fosfomycin for one day. When antibiotics are indicated for infections such as acute bacterial rhinosinusitis, cellulitis, community-acquired pneumonia or acute exacerbations of chronic obstructive pulmonary disease, typically five to seven days of treatment is sufficient; 10 days of treatment is usually recommended for pharyngitis due to Group A streptococcus.

* This applies once a clinical decision has been made that an antibiotic is, in fact, indicated. The scope of this article does not include a discussion on when antibiotics are and are not indicated for the selected clinical condition; for example, the use of antibiotics in COPD exacerbations is controversial.(28-30)

Balancing the long and the short of antibiotic durations: pointers for practice

So, you’ve read this entire article. How are you going to use what you’ve read here in your daily clinical practice? To help you, I will discuss three practical questions that often come up in practice.

Practice Question 1: Can an antibiotic be stopped before its full treatment course if a patient is “feeling better”? There is some thought that continuing antibiotics past resolution of symptoms for acute bacterial infections does not afford any benefits and probably selects for antibiotic resistance.(35) If patients feel substantially better with resolution of symptoms of infection, a reasonable approach may be to advise them to contact their clinician to determine whether the antibiotic can be stopped. This requires clinicians to be receptive to the concept of “antibiotic deprescribing” and not fear customizing duration of therapy on a patient-specific basis.

Practice Question 2: Should a pharmacist contact a prescriber to cut back on the days’ supply quantity if the pharmacist feels the antibiotic is being prescribed for an excessive duration? Can or should the pharmacist do so within their own scope? This is an interesting predicament. Consider this scenario. You are a pharmacist caring for an adult patient who presents to your pharmacy with a prescription for amoxicillin 500 mg three times daily for 14 days. Upon questioning the patient, you deduce that they are likely being treated for uncomplicated acute bacterial rhinosinusitis. You review the 2014 Canadian guidelines which state a 10-day course of amoxicillin is suggested.(25) You take a look at the 2012 IDSA guidelines that suggest a five- to sevenday treatment course would suffice.(24) Notwithstanding that the treatment durations differ, neither of these guidelines suggest a 14-day treatment course would be appropriate.

I would encourage pharmacists to implement an antibiotic callback system, where patients would be contacted routinely on Day 3 of antibiotic treatment to follow up on their clinical status and asssess for any safety concerns.

In my opinion, this presents a wonderful teachable moment for the pharmacist to educate both the prescriber as well as the patient about the risks of excessive antibiotic exposure. In this scenario, it may be worth a phone call or fax to the prescriber to review current best practices. Irrespective of the antibiotic treatment duration prescribed, I would encourage pharmacists to implement an antibiotic callback system, where patients would be contacted routinely on Day 3 of antibiotic treatment to follow up on their clinical status and assess for any safety concerns.(36,37) This follow-up may trigger a collaborative opportunity with a prescriber. For example, if a prescriber wanted to stick with prescribing a 14-day treatment course for acute bacterial rhinosinusitis initially, but the patient has improved after Day 3, the prescriber may feel more comfortable accepting the pharmacist’s suggestion to shorten that antibiotic course to five days.

Practice Question 3: Should pharmacists abandon the practice of counselling patients to complete their antibiotic course and “take until finished”? A final word about conventional advice to complete the course of antibiotics. Historically, many of us were trained to counsel patients to complete their course of antibiotics. In fact, this messaging is also seen in some public health campaigns about antibiotic awareness. When one examines the rationale behind this advice, it appears that the evidence to support this mantra of “take until finished” is predicated on a myth that completing antibiotics too early may increase the risk of antibiotic resistance.(38)

Indeed, formulaic approaches to antibiotic advice can be problematic. Pharmacists will need to become more comfortable in understanding the nuances around antibiotic prescribing durations, if we are truly going to embrace our role as antibiotic stewards. I would challenge pharmacists to avoid affixing the classic “Take until finished” auxiliary label on all antibiotic vials, as we’ve been trained to do. The use of this auxiliary label may in fact require careful thought. For example, it may be appropriate to indicate “Take until finished” for a patient taking a threeday antibiotic course for acute uncomplicated cystitis, but the auxiliary label should not be automatically placed on the vial of an antibiotic that may be appropriately reassessed earlier than the prescribed completion date.

Summary

The World Health Organization’s campaign on antimicrobial resistance includes the slogan “Antibiotics: Handle With Care.”(2) As we mark World Antibiotic Awareness Week this November, we have an opportunity to raise awareness among the public and stakeholders about the importance of ensuring that antibiotic use is necessary, safe and effective. It is of public health importance that we showcase the unique role that pharmacists have in facilitating appropriate antibiotic decision-making. To slow the progression of antibiotic-resistant bacteria, all healthcare professionals must strengthen their efforts to address this issue. Pharmacists have a responsibility to assist in the war on antibiotic resistance as stewards in each healthcare setting, especially in the outpatient setting where most antibiotics are prescribed. Pharmacists need to routinely assess whether patients may be exposed to antibiotics unnecessarily. Part of this assessment includes ensuring that the course of antibiotics is not too long, not too short, and just right. Suzanne Singh (suzanne.singh@sinaihealth.ca) is a pharmacist with the Mount Sinai Academic Family Health Team in Toronto, ON and an adjunct lecturer at the Department of Family and Community Medicine, University of Toronto. She is a strong advocate for enhancing the role of the pharmacist within integrated and innovative primary care practice models. REFERENCES

A primer on common ailments managed by nonprescription products

PATIENT SCENARIO

TOOTH BE TOLD: COMBOGESIC MAY CHANGE DENTAL PAIN MANAGEMENT

Case

CC, a healthy 23-year-old male, presents to your pharmacy with a printed postop sheet from his dentist. It provides instructions on post-procedure pain relief (regular strength ibuprofen or extra strength acetaminophen, taken according to OTC product labelling) and oral hygiene (antibacterial mouthwash). You learn that CC had a damaged tooth extracted yesterday. He is complaining about the pain, although itâ&#x20AC;&#x2122;s not severe and has no red flag features. Neither ibuprofen nor acetaminophen has provided adequate pain relief. CC is wondering if there is anything else he can try or if he should contact his dentist for a prescription. He was prescribed Tylenol No. 3 following a previous extraction and found this worked well. CC has no medical conditions or allergies, and is not taking any medications. He consumes alcohol occasionally and does not smoke.

Background

Oral pain affects a large number of Canadians. In fact, 11.7% of 5,284 survey respondents reported experiencing mouth pain in the past 12 months.(1) Oral pain is significantly more prevalent among 32

There is growing evidence that combining simple analgesics, namely acetaminophen and ibuprofen, provides greater acute dental pain relief than either analgesic alone. adolescents and younger adults, those in lower income groups, those who avoided a dental professional because of cost, and those with untreated tooth decay.(1) The most common forms of oral pain are acute in nature and can result from pathological conditions or disorders related to somatic and neurological structures.(2) Pain can be attributed to conditions affecting the hard tissues (e.g., caries of enamel, dentine) or those affecting soft tissue and supporting bone (e.g., gingivitis, periodontitis), some of which may necessitate dental intervention.(2) Table 1 outlines traditional analgesic regimens for managing postprocedural dental pain. Dental interventions anticipated to cause mild pain include frenectomies and simple extractions (e.g., removal of visible

tooth); those expected to cause moderate pain include implant surgeries and surgical extractions; and interventions predicted to cause severe pain include partial or full bony impaction surgeries and periodontal surgeries.(3)

Case analysis

Despite the large number of nonprescription products marketed for pain and fever, most consist of one of four active ingredients: acetaminophen, acetylsalicylic acid, ibuprofen or naproxen. However, there is growing evidence that combining simple analgesics, namely acetaminophen and ibuprofen, provides greater acute dental pain relief than either analgesic alone.(4-6) For example, one randomized controlled trial of 408 adults experiencing moderate to severe pain after surgical removal of impacted third molars, showed that a fixed-dose combination product of acetaminophen 975 mg and ibuprofen 292.5 mg/day provided significantly superior analgesia over equivalent daily monotherapy doses of either ingredient alone in the initial 48-hours after extraction. More specifically, the fixeddose combination provided a significantly shorter onset of meaningful pain relief, reduced the consumption of opioid rescue medication, and lowered maximum pain scores. This was achieved without compromising the well-established safety profile of either active constituent.(6) Simple analgesics may also have equivalent or superior efficacy when compared with opioids for postextraction dental pain; as such, routine opioid prescribing for post-extraction dental pain must be questioned because of the potential morbidity and longterm consequences of opioid use.(7,8) Evidence suggests that for opioid-naĂŻve patients, filling a prescription for an opioid pain medication following tooth extraction is associated with a greater risk of ongoing persistent opioid use.(7) Multimodal analgesia (i.e., combining medications with different mechanisms of action) is often recommended as an alternative to opioids for acute dental

pain.(6) Combining simple analgesics, in particular, may offer effective pain relief while causing fewer acute adverse events than opioid-containing alternatives. In 2019, Health Canada approved Combogesic—the first nonprescription fixed-dose combination of simple analgesics. This product contains acetaminophen 325 mg and ibuprofen 97.5 mg per tablet and is indicated for the treatment of acute mild to moderate pain in adults. Acetaminophen is believed to act by inhibiting cyclooxygenase (COX) (and subsequent prostaglandin synthesis) within the central nervous system and via activation of central serotonergic pathways. Ibuprofen, on the other hand, is a traditional nonsteroidal anti-inflammatory drug (NSAID) that decreases the synthesis of pain and inflammatory-promoting prostaglandins via nonselective inhibition of COX-1 and COX-2. Note, however, that the antiinflammatory activity of ibuprofen is considered negligible at self-care doses.(9) The introduction of Combogesic may provide impetus for updating current guidelines on the management of postprocedural dental pain. Traditionally, the combination of acetaminophen and ibuprofen has been reserved for dental interventions causing moderate to severe pain (Table 1). However, Combogesic’s indication for acute mild to moderate pain challenges this recommendation and suggests utility in less severe cases of dental pain. Changes to recommendations may

DID YOU KNOW… Combogesic is also indicated for the reduction of fever in adults and can be used for this purpose for up to three days (without further assessment by an appropriate healthcare provider). However, to date, findings of superiority relative to ibuprofen or acetaminophen alone are limited to dental pain in adults. As such, Combogesic’s efficacy may not be generalizable to other indications (including fever), other types of pain, or other patient populations. Pharmacists must exercise their professional judgment when considering Combogesic use for indications and populations that lack published evidence.

also be on the horizon for more severe postprocedural dental pain with the approval of higher-strength nonprescription combination analgesics such as Advil Dual Action (containing ibuprofen 250 mg and acetaminophen 500 mg) in the United States.(10) At a minimum, the introduction of nonprescription combination analgesics offers convenient formulations for achieving multimodal analgesia when indicated.

Recommendation

Removal of a damaged tooth is considered a simple extraction and is anticipated to cause mild pain. CC may take one or two Combogesic tablets every six hours. If his pain does not respond to two tablets, three tablets may be taken at subsequent doses, if advised by his dentist. The maximum recommended dose for acute pain is 12 tablets over a 24-hour period for no more than five days (without further assessment by an appropriate healthcare provider). CC should be warned to avoid taking this product with other acetaminophen- or ibuprofen-containing products. Counsel CC about the adverse effects associated with the combination product (which are similar to those of the individual drug components).(4) Follow up with CC within 72 hours to ensure adequate pain relief and that no alarming signs or symptoms have emerged. Note: Combogesic is expected to be available in late 2020/early 2021.

YOUR IMMUNE SYSTEM MAY SLOW DOWN, BUT YOU DON’T HAVE TO. FOR ADULTS 65+

Preventing the flu is your choice. In a study of 31,000 people over 65 in the US and Canada, FLUZONE® High-Dose was demonstrated to be

24% MORE EFFECTIVE than our standard dose vaccine* in protecting seniors from the flu. If you’re 65+, vaccination is one of the best ways to protect yourself from the flu. Ask your healthcare provider for the FLUZONE® High-Dose flu shot and get protected now.

*Vs. standard dose FLUZONE® vaccine against laboratory-confirmed influenza caused by any viral type or subtype.

WWW.FLUZONE.CA

FLUZONE® High-Dose is a vaccine used to prevent influenza in adults 65 years of age and older. Influenza (or flu) is an infection caused by the influenza virus. Annual vaccination using the current vaccine is recommended for prevention against influenza as immunity declines in the year following vaccination. Persons with a history of severe allergic reaction to eggs or egg products or any component of FLUZONE® High-Dose should not receive the vaccine. FLUZONE® High-Dose will only protect against the strains of influenza virus contained in the vaccine or those that are closely related. FLUZONE® High-Dose will not protect against any other strains of influenza virus. FLUZONE® High-Dose is not indicated for the prevention of hospitalization or death after the onset of disease. As with all vaccines, FLUZONE® High-Dose does not protect 100% of people immunized. Allergic reactions can occur. The most common side effects are pain at the injection site and muscle ache. Contact your healthcare provider to see if this vaccine is right for you. For more information, visit www.sanofi.ca. FLUZONE® is a trademark of Sanofi Pasteur.

OTC Counselling Tips

A series of tip sheets created by final-year pharmacy students at the University of Waterloo

“B” HEALTHY: VITAMIN B12 DEFICIENCY IN RECURRENT APHTHOUS ULCERS Vitamin B12 is used by the body for protein and carbohydrate synthesis.(1) Vitamin B12 deficiencies in Canada are rare, but have several different causes and sequelae. Among these sequelae is recurrent aphthous ulceration from diminished mucosal repair.(1) / BY ANDREW SAV0

What are aphthous ulcers?(1-3)

Prevalence of aphthous ulcers is as high as

• Aphthous ulcers, also known as canker sores, are inflammatory lesions of the oral mucosa.

25%

(3)

•  Associated problems include pain, difficulty eating or talking, and decreased quality of life. •  Possible causes include stress, mucosal damage, some medications, SLS (sodium lauryl sulfate), some foods (e.g. spicy, acidic food), genetic factors or vitamin deficiencies.

RISK FACTORS(2) • YOUNG ADULTS • FEMALE • FAMILY HISTORY

Shutterstock

• RECENTLY QUIT SMOKING

Within 3 months, recurrence rates are as high as

50%

(3)

It’s been hypothesized that YOUNG ADULTS more often get canker sores due to their less nutritious diets, leading to vitamin deficiencies. Several vitamin deficiencies, especially vitamin B12, are thought to contribute to recurrent aphthous ulcers.(1) A potential mechanism for this is decreased nucleotide and macromolecule synthesis and subsequent reduced ability to repair the mucosa.(1)

If there is no improvement after 6 months of vitamin B12 supplementation, refer to a physician. It may be herpetiform ulceration, Behçet syndrome, systemic lupus erythematosus, irritable bowel disease or something else!(2,4) (continued on page 36) Andrew Savo is in his final year of the PharmD program at the University of Waterloo School of Pharmacy. He loves learning about infectious diseases and mental health, and hopes to obtain a career with an emphasis in one of these areas.

Vitamin B12 CASE STUDY

CLINICAL TRIAL

One case study has shown that in patients with low B12 levels and recurrent aphthous ulcers, normalizing B12 levels led to no recurrences at least 6 months later.(6)

In a randomized clinical trial, 74% of patients treated with sublingual vitamin B12 1000 mcg daily had no recurrent ulcers after 6 months compared with 32% of patients in the placebo arm (p<0.01), regardless of B12 levels.(7)

Assessing diet may be useful in making the decision to treat with B12 especially in vegan patients.(6,8) Remind patients to let sublingual B12 dissolve under the tongue for a couple of minutes (do not chew or swallow it).

“B” HELPFUL(3,5)

While considering etiology, don’t forget to address the patient’s pain! Try topical protectants, avoid NSAIDs.

“B” MINDFUL(4)

Aphthous ulcers will often recur within weeks to months following recovery. Taking the time to help patients prevent recurrences shows them you care.

Aphthous ulcers can be prevented by remembering and implementing this simple mnemonic: CANKER (1,4,7) CARE for your mouth—brush teeth regularly AVOID acidic, spicy, salty foods NO SLS, an ingredient in some toothpastes KEEP chips and other mouth-damaging foods away

“B” SUSPICIOUS(9)

Other signs and symptoms of vitamin B12 deficiency might help guide you: Fatigue

Vegan diet

Anemia

EAT foods rich in vitamin B12 or use supplements REDUCE stress—meditation, focused breathing and guided imagery may help, though these measures have not been directly studied in aphthous ulcer prevention

Let’s “B” smart

All patients with recurrent aphthous ulcers should be screened for symptoms and likelihood of vitamin B12 deficiency. Some evidence shows supplementation to be useful regardless of vitamin B12 levels, so it is reasonable to recommend B12 supplementation in patients suspected of having low levels.(7)

“B” CAREFUL(3,4)

Some red flags that may warrant referral include: Impaired eating

>5 ulcers

Ulcers >1 cm in diameter

Fever

Ulcers lasting longer than 14 days Scarring due to aphthae

Empowering pharmacists,

ONE APP AT A TIME BY ROSALIND STEFANAC / PHOTOGRAPHY BY JENNIFER ROBERTS

MICHAEL DO has created technology that gives pharmacists the time to perform at the top of their patient care game and makes it easier for patients to take their medications properly.

[Vol.7 No.9] NOVEMBER 2020

T

oronto-based pharmacist Michael Do is passionate about empowering patients (and their pharmacists) with technology. So much so, he’s been working 60 hours a week for the last three months to fine-tune the healthcare apps he and his team at MedEssist have been developing— all while still managing a busy downtown Toronto pharmacy himself. Do founded his healthcare technology company, MedEssist, in November 2018 after spending eight years as a community pharmacist. Drawing on his experience in the community, he saw gaps in medication management and adherence among patients that he felt technology solutions could remedy. He also wanted to give pharmacists a way to manage their workloads more efficiently, while being able to grow their businesses and improve their overall image as doing more than “counting pills.” His instincts around the need for technology solutions was bang on. In a short time, MedEssist apps are already being endorsed by pharmacy associations across the country and in use by thousands of pharmacies and patients. And Do says there are many more technology solutions he wants to bring to fruition in the coming years.

Tell us more about what these apps do?

MedEssist Lead Developer Bashir Egeh gave up his job as a community pharmacist and moved provinces to code full-time. “Pharmacists have a lot to do— especially now. I’m hoping what we’re developing will make their lives easier so they can focus on patients.”

“THE HEALTHCARE SYSTEM IS CHANGING, AND PHARMACIES CAN AND SHOULD PLAY A BIGGER ROLE IN SHAPING THAT CHANGE.”

When we first launched, our mobile app was a tool to help patients with their medications. Prior, we were seeing patients leave the pharmacy confident about the medication we had explained to them and yet still have issues and missing doses. With the app, patients see a picture of what the pills look like, and then get a reminder about how and when to take them. And it’s grown from there. Now we provide a platform to help pharmacies manage patients for their flu shots and COVID-19 tests too. (All the apps are free for patients and pharmacies pay a nominal subscription fee for access to the platform and tools.)

How do you run a new business and still manage a pharmacy? I have full

control over the schedule at the pharmacy and am only there about five hours a week now, so that helps. I also like that I have been able to use our apps at this store for ‘real-world’ testing. On the MedEssist side, I also have a great team and couldn’t do it without them.

Tell us about your team. I have five

How are you marketing your solutions? Initially we went pharmacy to

Were you always into technology?

You’re often asked to speak to pharmacy students. Tell us more about that. There are two different reasons

full-time employees (two are experienced pharmacists), as well as part-time staff and pharmacy students. Pharmacist Bashir Egeh is the lead developer and I like putting a spotlight on him because not a lot of pharmacists code to the level that he does. He does the heavy lifting and I do content design and lighter coding. But in a true sign of the times, I have yet to meet him in person because we hired him after the COVID-19 shut-down. I did some coding in high school, but don’t have any official training.

What are some of the challenges you’ve faced?

I’m working a lot and when you start off, everything is hard. But then again, most pharmacists are working really hard during this time. The fact I’m building solutions for 40

them, to make work life easier, inspires me. Pharmacists and patients still don’t know a lot about technology so there is a lot of room to grow in this aspect, too. It’s exciting getting patients and pharmacists more comfortable with using technology.

NOVEMBER 2020 [Vol.7 No.9]

pharmacy, asking pharmacists to try our tools and gain our trust. I don’t think you can just throw an ad online and expect people to trust you. We’ve made a lot of progress in several provinces with the support of pharmacy associations. In Nova Scotia, for example, the association reached out to us because they were looking for solutions and it went from there.

I get invited, either to talk about community pharmacy and how to have a successful student rotation, or to discuss technology in pharmacy. I’ve given talks at both the University of Toronto and University of Waterloo. With any opportunity to talk to students, my goal is always to expand their thinking in some way. I love working with students too. We have student rotations at


both my pharmacy and with MedEssist. I feel like if I can teach them something or motivate them in some way, then I’m having a positive influence on the countless patients that student is going help throughout their career.

How did you know you were successful? By the fact that lots of people

are using our apps without any issues. We had more than 10,000 patients register for the flu shot using our platform even before flu season began. I think that’s pretty incredible.

What do you attribute to your success so far, especially with so many competitors in the market? All of

our solutions are fundamentally unique to pharmacy, and I believe could have only been built by a pharmacist. I think that’s why our pharmacies love working with us. I think another reason for our success is how we’ve been able to build trust both with patients and with other pharmacists. Eventually the trust that we’ve built, by holding ourselves to a higher standard, will be the most valuable asset we will ever own.

What’s next on the agenda?

Once pharmacists try our products, they end up contacting us with ideas of what they want us to make next. It’s a long list. COVID-19 vaccinations are on the horizon. A lot of these vaccines are two-dose, so being able to help pharmacists and patients get those doses while supplies are limited is going to be very important.

What’s your advice to other pharmacists who want to innovate?

“I think another reason for our success is how we’ve been able to build trust both with patients and with other pharmacists. Eventually the trust that we’ve built, by holding ourselves to a higher standard, will be the most valuable asset we will ever own.”

I think working as a pharmacist you pick up so many important soft skills that can be useful with anything you want to do. Skills such as being able to work in a high-paced environment, communicating through all sorts of barriers, problem-solving, being extremely attentive and detailed, or being a lifelong learner. If you are mindful of these things, you can hone these skills within the pharmacy in order to solve all sorts of problems in the healthcare system. The healthcare system is changing, and pharmacies can and should play a bigger role in shaping that change.

This 1-minute video explains the MedEssist app: https://www.youtube.com/ watch?v=dh2HC7f9u8g

Do you have work-life balance at this point? No. When you launch something it’s

a limitless amount of time you can put into it. But I know I can’t sustain this, and after we finish implementing our COVID-19 app, I’ll definitely scale back.

Creative thoughts and smart ideas for pharmacy owners and managers

PAVITHRA RAVI RPh

WHICH form of automation is the right fit for my practice?

A retail operation that sees patients come consistently for refills of their vial medication may benefit from vial packaging automation, whereas one that supports a LTC facility would benefit from blister card packaging. It’s also important to think ahead. What are your plans for future services/expansion? Your automation systems should be configurable and able to integrate with other technology as your practice changes and grows.

WHEN is the right time for automation at my store?

ILLUSTRATION BY SPENCER FLOCK

STRATEGY

HOW TO PLAN FOR PHARMACY AUTOMATION Automation is a significant investment that more pharmacies are considering. Here are some important questions to ask before deciding which technology is right for your pharmacy.

WHAT are the needs at your practice?

Automation can be helpful, but it is only as good as its purpose. One of the first considerations before you implement any form of automation is to know what are you trying to accomplish. Efficiency is often the root contributor to successfully implementing automation in pharmacy practice. Pharmacies may be looking to free up labour for relationship building, services and other projects. That kind of investment can reap benefits in terms of patient loyalty: patients who have a personalized relationship with staff are 46

more likely to return and to recommend you to others. A sudden spike in prescription volumes, disruptions in available labour, or general growth can also spur the need for automation.

HOW will I implement automation?

Take a look at your current prescription count. What is your range of refills vs. new prescriptions? How many of your current patients are on blister cards? It’s important to understand how your staff ’s time is currently being used in your pharmacy. Depending on what you find out, various forms of automation are available to help automate routine processes: from strip-packaging medication to filling vials or packaging blister cards. Automation can even go a step further and support technical checks to ensure the right pill has been packaged.

NOVEMBER 2020 [Vol.7 No.9]

There are factors to consider in timing. A new store has more options for building the floor plan around the machinery, whereas with a store that is currently operating, you need to work with the space you have. However, there are various models of machinery available to work within your workflow. To develop your business case for automation, take into account both your current and forecasted script volumes for the prescriptions to be handled by automation, as well as your current workflow and staffing resources.

WHO is the right partner for me?

The right partner/vendor can help you navigate through these decisions. Look for vendors who help you understand the business case for your specific automation investment. Your labour situation, script count and growth plans are unique to you and cannot be generalized. Look for a partner who truly understands your pharmacy’s workflow. Identifying a business case is the first step, but implementation is also crucial to see a return on your investment. Is your vendor able to support change management in your store? Finally, does your vendor offer support once you are up and running? Staff may change, your needs may change; it’s important to have a partner in this journey who will support you and your practice. Take the time to evaluate, innovate and personalize automation to your practice needs. Pavithra Ravi is a healthcare consultant with a background in retail pharmacy.
