A Genotype Stratification Study for Pharmacokinetics and Pharmacodynamics of Amitriptyline in Healthy Male Subjects
August 9, 2015 updated by: Hyeong-Seok Lim, Asan Medical Center
A Single Dose, Double-blind, Genotype-based Stratification Study to Explore the Pharmacokinetics and Pharmacodynamics of Amitriptyline According to CYP2D6 and CYP2C19 Polymorphisms in Healthy Korean Male Adult Subjects
A total of 24 healthy Korean male subjects will receive a single oral dose of amitriptyline, 25 mg.
Subjects will be enrolled in this study based on their cytochrome P450 2D6 and cytochrome P450 2C19 genotypes, and serial blood sampling will be done for plasma concentrations of amitriptyline, nortriptyline, and their metabolites.
Various pharmacodynamic markers related to the adverse event of amitriptyline will be measured serially during the study.
