Abstract:
OBJECTIVE: To study the bioequivalence of domestic oxcarbazepine dispersible tablets. METHODS: 20 healthy male volunteers were randomly given oxcarbazepine dispersible tablets (test tablet) and oxcarbazepine tablets (reference tablet) via p.o. The plasma concentration of active metabolite (MHD) of oxcarbazepine were determined by HPLC. 3p97 software was used to calculate pharmacokinetic parameters and the bioequivalence of oxcarbazepine were evaluated. RESULTS: After treatment main pharmacokinetic parameters of test tablet vs. reference tablet were as follows: Cmax(4.231?0.841) ?g?mL-1 vs. (4.350?0.861) ?g?mL-1; tmax(4.13?0.43) h vs. (4.28?0.44) h; t1/2(14.17?2.66) h vs. (14.44?2.09) h; AUC0~60 (113.00?22.25) mg?h?L-1 vs. (118.11?14.20) mg?h?L-1; AUC0~∞(126.35?20.94) mg?h?L-1 vs. (130.54?16.17) mg?h?L-1. The relative bioavailability of test tablet to reference tablet was (95.67?12.80)%. CONCLUSION: Two kinds of tablets were bioequivalent.
