What’s the Problems for Pain Control

Especially Moderate to Severe Pain :

1. Almost all the pain killer for moderate to severe pain are:

(1) Narcotics with addiction

(2) Respiratory suppression may cause death

(3) possible vasodialation

(4) Reduce GI motility

(5) Convulsant effects

2. Not a moderate to severe (M/S) pain killer for post operation pain has a duration longer than one day.

An Innovative Cold Tail-Flick Test: Cold Ethanol Tail-Flick Test Kappa Receptor Efficacy Study

Abstract

An innovative antinociceptive test, the cold ethanol tail-flick test (CET), was developed for evaluating the actions of opioid analgesics. To select an optimal operation temperature range for the CET, temperatures from -5 degrees C to -30 degrees C were screened. After screening, temperatures ranging between -20 degrees C and -30 degrees C were both strong and effective enough to act as a noxious cold stimulus. In the following study, -20 degrees C was selected as the cold stimulus for the CET. The sensitivity and specificity of this test were challenged by opioid analgesics: an agonist (morphine) and two agonist-antagonists (buprenorphine and nalbuphine), two tranquilizers (droperidol and diazepam), and four nonopioid analgesics (acetaminophen, aspirin, indomethacin, and ketoprofen). The sensitivity of the CET was also compared with the assays using heat (radiant heat and hot water). The AD50 values determined by the CET for morphine, buprenorphine, and nalbuphine were 0.16 mg/kg, 0.22 micrograms/kg, and 0.19 mg/kg, respectively. Naloxone, an opioid antagonist, blocked the antinociceptive effects of these opioids which were determined by the CET. Furthermore, the tranquilizers and nonopioid analgesics did not show any activity in the CET. Our results show that not only can the CET assess the antinociceptive activity of both opioid agonist and mixed agonist-antagonist, it also possess the characteristics of sensitivity, specificity, simplicity, and reproducibility.

Residual Liver Function –GSPMethod

Development of Diagnostic Kit for Residual Liver Function – GSP Method

Comparison of Various Quantitative Liver Function Tests

Method Advantages

Child-Pugh Simple, convenient, semi- quantitative

Disadvantages

Qualitative. The Child-Pugh classification uses factors such as ascites and encephalopathy to evaluate liver function; therefore, it is mainly used to assess severe dysfunction.

ICG Quantitative i.v. bolus, complex (many blood sampling), foreign compound, blood flow only.

GSP (Galactose)

1. Simple (single blood sampling)

2. Quantitative, blood flow and enzyme activity, not affected by CYP or conjugated metabolic system

3. Use strip to rapid detect QLFT, Point-ofCare

4. Galactose is a natural and safe compound

5. The GSPand OGSPtests appeared to be more appropriate than the Child-Pugh and MELD scores for patients with liver dysfunction across the entire normal-to-severe spectrum.

3 min i.v. Bolus, fasting.

Galactose Metabolized in Liver Becomes Glucose-1-Phosphate Then

Produced ATP, Not Glucose (Diabetes Mellitus Patient Can Use)

Galactose

90% galactose metabolized in the liver

1. Galactose is extensively metabolized by liver - reflect the CLint

2. Galactose is highly extracted by liver – reflect the QH, hepatic blood flow. When not saturated.

3. When galactose saturated, the clearance will reflect the hepatic enzymes activities.

CLint reflect the hepatic enzymes activities QH reflect the hepatic flow

pathway

Hepatic Clearance Correlated with Hepatic Blood Flow and Enzymes Activities

• Galactose is extensively metabolized by liver - reflect the CLint

• Galactose is highly extracted by liver – reflect the QH

CLint reflect the hepatic enzymes activities QH reflect the hepatic flow

Difference of galactose blood concentration at different time point between 51 normal healthy volunteers and 36 patients with cirrhosis after 0.5 g/kg galactose was infused intravenously for 3 min. The concentration 40, 50 and 60 min after infusion give highly significant difference between these two groups.

Point of Care, Clinically Useful Galactose Single Point (GSP) and Oral GSP (OGSP) Method

• Oral 0.5g/kg or i.v. infused (3~5min.) of galactose, and measuring whole blood galactose concentration at 60 minutes.

肝功能不全病患的藥動學試驗基準

-臨床試驗設計、數據分析以及對劑量 調整與標示的影響

肝功能評估-推薦方法之一

2、半乳糖單點法(Galactose Single Point, GSP) 本法乃是由唐鴻舜及胡幼圃發表於1992年之Digestion期刊中。GSP為於空腹時, 三分鐘快速靜脈輸注0.5 g/kg的半乳糖,經過60分鐘後,測量受試者血中半乳糖的

濃度,即為其GSP值(單位為g/ml)。血中半乳糖濃度,和肝功能異常有靈敏的 相關性,且實驗數據顯示GSP值與肝功能異常的程度有非常顯著的關係。因此,

可經由受試者的GSP值來評估其肝臟的剩餘功能,評估方法如下:

(1)GSP值小於280g/ml:肝功能正常或受損輕微。

(2)GSP值介於280與480g/ml之間:肝功能受損為中度(可能為慢性肝炎患者)。

(3)GSP值大於480g/ml:肝功能受損較嚴重(可能為肝硬化或肝癌患者)。

“Warnings and precautions” and “contraindications” for any liver impairment

Immune-mediated hepatitis: Monitor for changes in liver function. Withhold for moderate and permanently discontinue for severe or life-threatening transaminase or total bilirubin elevation.

Dose modification

Use in Patients with Hepatic Impairment

CYP3A5 和

CYP2J2 代

• Avoid the use of XARELTO in patients with moderate and severe hepatic impairment or with any hepatic disease associated with coagulopathy. Hepatic impairment:

• Avoid use in patients with moderate and severe hepatic impairment or with any degree of hepatic disease associated with coagulopathy.

Hepatic Impairment

Crestor is contraindicated in patients with active liver disease.

Chronic alcohol liver disease ; Crestor should be used with caution in these patients.

Rosuva statin

2. Valproic acid (Depakene)

5. Phenytoin Phenytoin is primarily metabolized by the liver, specifically by the enzyme CYP2C9

Mild to moderate impairment: Not recommended for use in hepatic disease

Has liver disease, the dose of phenytoin may need to be adjusted to avoid potential toxicity or insufficient therapeutic effects.
