摘  要:目的:建立人血浆中苯磺酸氨氯地平高效液相色谱-质谱联用测定法(HPLC-MS-MS),并研究苯磺酸氨氯地平在健康人体内的药动学行为,评价两片剂的生物等效性.方法:采用双交叉试验设计,血样用乙醚-二氯甲烷(2:1)混合液提取,HPLC-MS-MS分离测定,根据血药浓度.时间数据估算主要药动学参数和相对生物利用度,评价生物等效性.结果:苯磺酸氨氯地平的线性范围为0.1986~15.8880ng/mL.苯磺酸氨氯地平受试片和参比片的主要药动学参数分别是:Cmax为(5.9511±2.3623)和(5.5517±1.9781)ng/mL,Tmax分别为(5.89±2.25)和(5.83±1.54)h,AUC(04)分别为(195.6±79.4)和(212.7±72.1)ng/mL·h,AUC(0-∞)分别为(226.1±91.2)和(240.3±82.3)ng/mL·h.结论:本法简便、灵敏、准确,统计分析结果表明两片剂具有生物等效性.Objective: To establish an HPLC-MS-MS method for determinating the concentration of amlodipine in human plasma, and to investigate the pharmacokineties and bioequivalence of two amlodipine besylate tablets in Chinese healthy volunteer. Method: Two-way crossover trial is performed. Plasma samples are extracted with ether-dichlormethane mixed liquor (2: 1) and determined by HPLC-MS-MS. The main pharmacokinetic parameters and relative bioavailability are estimated by plasma concentration-time data, and the bioequivalence is evaluated. Result: The parameters of amlodipine for test and reference formulations are as follows: Cmax, 5.9511 ± 2.3623 and 5.5517 ± 1.9781 ng/mL; Tmax, 5.89 ± 2.25 and 5.83 ± 1.54 h; AUC(0-t), 195.6 ± 79.4 and 212.7 ± 72.1 ng/mL·h,AUC(0-∞),226.1 ± 91.2 and 240.3 ± 82.3 ng/mL-h. Conclusion: HPLC-MS-MS method used in the study is sensitive, accurate and convenient. These 2 formulations ofamlodipine besylate are bioequivalent.
