Rood & Riddle Veterinary Pharmacy RRVP has received the USP <800> Hazardous Drug Handling Distinction by the Pharmacy Compounding Accreditation Board (PCAB). They were the 16th pharmacy in the United States (out of all pharmacieshuman and veterinary) to demonstrate compliance and receive this accreditation. The following steps were taken to complete: In 2018, RRVP completed a full new cleanroom addition as well as a remodel in the existing pharmacy, which was the first step in achieving compliance.

The second step named and certified an individual, Kelly Zaccarelli, RPh, HDDP, to move implementation forward. A hazardous drug designated person (HDDP) is responsible for creating, implementing, reviewing and updating policies and standard operating procedures (SOPs), employee training and competencies, and ensuring “environmental control” of locations where HDs are stored and handled.

The third step was to demonstrate compliance of all areas, which was accomplished with no deficiencies!

Based on USP 800, the recently released industry guidelines that describe practices and quality standards for handling hazardous drugs in healthcare settings aimed at promoting the safety of patients and workers as well as environmental protection standards, PCAB’s hazardous drug handling standards reflect the efforts of a broad collective of industry experts.

During the accreditation process we completed a full day rigorous survey to demonstrate compliance.

With the delay by USP <800> implementation in December 2019, RRVP proactively moved forward. Thanks goes to the RRVP team for not only practicing to the best standards, but now exceeding those standards as well.

WHAT DO WE KNOW ABOUT ULCERS?

by Dr. Kate Christie Board Certified Large Animal Internal Medicine QUESTION: What do we know about the causes and best treatments for ulcers?

DR. KATE CHRISTIE: Equine gastric ulcer syndrome is a common condition in the performance horse with upwards of 90% of horses having evidence of gastric ulceration within two to three months of intensive training. Frustratingly, clinical signs vary from horse to horse and gastroscopy remains the only definitive diagnosis for ulcer disease in the adult horse.

The majority of gastric ulcers occur in the non-glandular portion of the stomach and are associated with exposure of this area to the acidic contents of the stomach. Some of the most important conditions that increase exposure to stomach acids include long periods between eating and high levels of exercise and training. Ulcers can also be located in the glandular portion of the stomach, specifically in the pylorus or outflow tract of the stomach. Gastric ulcers in this region of the stomach are less completely understood, but may be associated with breakdown of natural protective barriers. Unlike other species, bacterial infection does not seem to play a role in equine gastric ulcer syndrome.

Once a diagnosis of gastric ulcer disease has been reached, treatment and management should be tailored to each individual horse. A combination of pharmaceutical intervention as well as environmental management is often the most successful. Horses that go long periods of time without access to forage, especially those on a high grain diet, are at increased risk of gastric ulcers.

Providing constant access to forage is key in the prevention and management of equine gastric ulcers. Adding alfalfa to the diet may also be helpful as it is naturally high in calcium and can act as a buffer for the highly acidic contents of the stomach.

Medications used to treat gastric ulcers in horses have the main goal of decreasing the acidity of the stomach. Commonly used medications include omeprazole (GastroGard, UlcerGard) and until recently ranitidine (Zantac). Sucralfate is also commonly administered as a coating agent to help heal ulcerations. GastroGard is the most commonly used medication and is the only medication with FDA approval for the treatment of gastric ulcers in horses.

A long-acting injectable omeprazole has shown promise and may offer an alternative to traditional omeprazole therapy although further study is needed. Glandular ulcers can be more difficult to treat and often require longer courses of treatment.

In some cases, treatment with a medication called misoprostol may be recommended if these ulcers fail to respond to GastroGard alone. The only way to confirm resolution of gastric ulcers is repeat gastroscopy which is typically recommended after a four-week course of treatment.

Dr. Kate Christie grew up in Halifax, Nova Scotia, where she developed her love of horses actively competing in the show hunter world and watching Standardbred racing at the track with her grandfather. She received her undergraduate degree in Life Sciences as well as a Master’s degree in Pharmacology and Toxicology from Queen’s University in Kingston, Ontario where she continued her riding career and further developed a passion for veterinary medicine. Kate graduated from the North Carolina State College of Veterinary Medicine in 2014 and went on to complete a year-long rotating hospital internship at Rood and Riddle Equine Hospital (2014-15) prior to entering a Large Animal Internal Medicine Residency at the University of Georgia. She became boarded in large animal internal medicine in 2018 at the completion of her residency program. Kate remained at the University of Georgia as a clinical associate professor for one year and is excited to be returning to Lexington to join the Rood and Riddle internal medicine team. Her professional interests include gastrointestinal disease, infectious and non-infectious respiratory disease, and equine pharmacology. Outside of work, Kate enjoys spending as much time as possible with her retired show jumper, Skye. When not in the saddle, she enjoys trail-running, hiking, traveling and speading time with her husband and daughter.

PRE-SALE MEDICATION REGS ‘A GOOD CHANGE’

by Dr. Bart Barber Ambulatory Veterinarian QUESTION: What is the veterinary perspective on the new pre-sale medication restrictions in force at public auctions in the United States?

DR. BART BARBER : From this veterinarian’s perspective, the changes that the sales companies have made are positive. The limitations that have been imposed add a degree of confidence to buyers while still allowing sellers and veterinarians to fully treat horses as needed with only a few exceptions.

There are some subtle differences but the changes for both sales companies are very similar. One of the new rules that each have applied is that only one non-steroidal antiinflammatory drug (NSAID) and one corticosteroid may be used. There can be no stacking of drugs within the classes. There are lots of drugs in each of these categories and they have similar actions and effects within each class. That said, there are differences that make drugs in each of those classes superior for treating specific conditions. For instance, one NSAID is preferred to treat pain associated with colic while another is preferred for musculoskeletal pain. Certain steroids are better suited for treating allergic reactions while others are best at treating head trauma. The point is that there are reasons why one NSAID or corticosteroid is chosen over another and why there are several different choices.

In the rare case that a horse has already been treated with one of these medications for a specific condition and another condition arises for which another medication in the same class is needed, decisions will need to be made. First and foremost the horse will be taken care of. It is important to point out that this situation would not automatically disqualify the horse from being sold. A positive test for multiple NSAIDs or corticosteroids merely gives the buyer the right to rescind the sale. The goal of the new regulations is not to limit treating horses appropriately but to limit indiscriminate stacking of NSAIDs and corticosteroids, which is in the best interest of the buyers, the sales process, the industry and, ultimately, the horse. It’s a good change. When the situation described above arises, it will be in the best interest of all parties to come together, use good judgment and horsemanship to determine intent, the best interests of the horse, and whether or not the process was compromised.

These occasions will likely be rare and I believe that even in these instances we will be able to care for the horses without compromising the intent of the rules.

Bronchodilators, including clenbuterol, have been limited in that they have been completely banned for a time period prior to the sale. There is a potential for abuse of these medications and again this is a positive change to protect the horse. When this change was announced some chose to not use this class of medications in horses at any age, for any condition and I believe that is a mistake. Taking this out of a veterinarian’s toolbox for use in foals could have fatal consequences. There are legitimate uses for these medications and they should be used when they are warranted. The sales companies have not limited their use when appropriate for age and condition, they have merely asked for disclosure.

The balancing of allowing for appropriate use and imposing rules to curtail abuse is difficult.

In this case it has been well thought out and will benefit all involved.

LEAVING DENTAL WORK TO THE VET

by Dr. Brad Tanner Ambulatory Veterninarian

QUESTION: Why is it important to have a veterinarian perform dental work on your horse?

Brad Tanner, DVM, DAVDC-EQ

DR. BRAD TANNER: Responsible horse owners have mental checklists of the things that need to be done each year for their horses. These include deworming, vaccinations, Coggins test, health certificate and of course annual floating. The annual float is a treatment for the condition of sharp enamel points. No treatment, be it antibiotics, anti-inflammatories, etc. should be administered without an examination and proper diagnosis.

Why should a dental float be any different?

“While

responsible owners are correct to have their horse’s teeth checked annually, the floating is not the most important thing happening — it is the exam.”

“Recognition

of abnormal dental wear or other pathology may be indication for dental radiographs or a CT scan to further investigate problematic teeth.”

“Our goal is to preserve functional occlusion of the teeth and allow continued grazing.”

The tooth of a horse continues to grow (erupt) throughout life. Those areas of the tooth that do not get worn away become long and sharp. Left to their own devices these sharp teeth may cause cuts in the cheeks and tongue (see below). These sharp teeth cause increased discomfort in performance horses as bit and bridle change head carriage which forces increased contact of these teeth with the cheek tissue. Dental floating is the necessary treatment for this common condition in the horse.

While responsible owners are correct to have their horse’s teeth checked annually, the floating is not the most important thing happening — it is the exam. A proper dental exam performed by your veterinarian can provide insight into your horse’s general health as well their oral health. This veterinarian has spent years of training in anatomy, physiology, medicine, surgery, imaging etc. and is equipped to recognize, diagnose and treat oral pain.

The dental examination will include assessing facial symmetry, bone enlargements, lymph nodes, draining tracts, maleruptions, malocclusions, soft tissue lacerations and abrasions. The exam will also include a close inspection of each tooth surface with a dental mirror or an oral camera. These close looks often show painful problematic teeth with cracks, fractures or feed packing that may need to be investigated with additional imaging.

Recognition of abnormal dental wear or other pathology may be indication for dental radiographs or a CT scan to further investigate problematic teeth. These imaging modalities are common practice in human medicine as the ADA (American Dental Association) recommends radiographs every couple of years, and with increased access to quality digital radiography this is also becoming more common in horses.

Horse teeth do develop cavities and these can lead to fracture, pain, and sometimes sinus infections. These problems can be avoided with early detection and treatment. The treatment for these is cavity fillings (restorations) and can be done as a routine standing This image shows damage to a horse’s tongue that has arisen from sharp points on the teeth. procedure.

Dr. Brad Tanner received his DVM from Auburn University in 2005 and completed an internship at Rood and Riddle thereafter. He is a shareholder in the clinic, where he focuses on advanced dentistry, primary care and reproduction. Tanner became board certified in equine dentistry in 2019.
