The study was performed to compare the bioavailability of two clopidogrel 75 mg tablet formulation (Clopidogrel from Sandoz as test formulation and Plavix from Sanofi- Synthelabo Ltda, Brazil, as reference formulation) in 42 volunteers of both sexes. The study was conducted open with randomized two period crossover design and a one week wash out period. Plasma samples were obtained over a 48 hour interval. The carboxylic acid of Clopidogrel, major metabolite of Clopidogrel, was analyzed by LC-MS-MS, in the presence of enalapril maleate as internal standard. With plasma concentration vs. time curves, data obtained from this metabolite, the following pharmacokinetics parameters were obtained: AUC 0-t , AUC 0-inf and C max . Geometric mean of Clopidogrel/Plavix 75 mg individual percent ratio was 100.33% AUC 0-t , 98.96% for AUC 0-inf and 105.83% for C max . The 9 0% confidence intervals .. View More»
