Comparative Bioequivalence Study of 2 Clopidogrel 75-mg Tablet Formulations in Moroccan Volunteers

Abstract

This study investigates the pharmacokinetic properties and bioequivalence of 2 formulations of clopidogrel tablets administered to a cohort of healthy Moroccan male volunteers. The primary objective was to assess the rate and extent of drug absorption from the test formulation in comparison to a reference formulation, focusing on critical parameters including maximum plasma concentration (C_max), area under the concentration-time curve from 0 to the last measurable time (AUC_0-t), and area under the concentration-time curve extrapolated to infinity (AUC_0-∞). The results revealed that the geometric mean ratios of C_max, AUC_0-t, and AUC_0–∞ for the test formulation relative to the reference formulation were 105.7%, 105.6%, and 105.6%, respectively. The 90% confidence intervals for these parameters fell within the predefined bioequivalence range of 80%-125%, indicating a statistically and clinically equivalent performance between the 2 formulations. This investigation sheds light on the pharmacokinetic behavior of clopidogrel in the context of the Moroccan male population, offering valuable insights into the comparability of formulations.
