Abstract
AIM To evaluate the bioequivalence of lamivudine tablets in healthy male volunteers. METHODS Twenty-two healthy volunteers in randomized 2×2 crossover study were given a single oral 100 mg dose of test or reference lamivudine tablets. The plasma concentrations were determined by LC-MS/MS, and the pharmacokinetic parameters were calculated and the bioequivalence of two formulations were evaluated by DAS program. RESULTS The main pharmacokinetic parameters for test and reference formulations were as follows: pmax were ( 881.4 ± 236. 8) and (985.0 ± 292.4)μg·L-1,tmaxwere(0.989±0.323)and(1.034±0.651)h,t1/2 were(2.889 ± 0.622)and(2.820 ± 0.368)h, AUC0→t were(3 435±627.7)and(3 504 ± 506.7)μg·h·L-1, AUC0→∞ were(3 529 ± 630.9)and(3 592 ±519.4) μg·h·L-1,respectively.The relative bioavailability of lamivudine was(98.45 ± 13.50)% . CONCLUSION The results show that the two lamivudine tablets made by two different corporations are bioequivalent. 关键词
