摘    要:目的:比较两种格列美脲制剂的人体生物等效性.方法:20名健康男性志愿者随机交叉口服单剂量格列美脲分散片(受试制剂)与格列美脲片(参比制剂)2 mg,采用HPLC-MS法测定血浆中格列美脲浓度,用DAS 2.1软件计算药动学参数和生物利用度.结果:口服格列美脲受试制剂与参比制剂后的药动学参数分别为Cmax( 135.4±40.3)和(146.5±39.2) ng·ml-1,tmax(3.2±1.2)和(2.8±0.9)h,t1/2(7.3±3.9)和(6.7±2.8)h,AUC0~36 (757.1±217.2)和(849.4±250.4 )ng·h·ml-1,AUC0~∞(784.0±217.4)和(871.5±265.2) ng·h·ml-1.受试制剂的相对生物利用度为(90.7±17.5)%.结论:两种格列美脲制剂具有生物等效性.

Abstract:Objective:To investigate the bioequivalence of two glimepiride preparations in healthy volunteers.Method:2 mg glimepiride dispersible tablets or glimepiride tablets were given to 20 healthy male volunteers in a randomized two-way crossover design and the plasma drug concentration was assayed by LC-MS.The pharmacokinetic parameters were calculated by DAS 2.1 software.Result: The main pharmacokinetic parameters of test and reference preparations were as follows;C_(max) of(135.4±40.3) ng·ml~(-1) and (146.5±39.2) ng-ml~(-1),t_(max) of(3.2±1.2) h and(2.8±0.9)h,t_(1/2) of(7.3±3.9)h and(6.7±2.8)h,AUC_(0-36) of(757.1±217.2)ng·h·ml~(-1) and(849.4±250.4) ng·h·ml~(-1),AUC_(0_∞) of(784.0±217.4) and(871.5±265.2) ng·h·ml~(-1),respectively. The relative bioavailability was(90.7±17.5)%.Conclusion:The two formulations are bioequivalent.
Keywords:Glimepiride  Pharmacokinetics  Bioequivalence  LC-MS
