摘    要:目的评价苯磺酸左旋氨氯地平片(分散片)在健康人体内的药物动力学与生物等效性。方法18名健康志愿者随机交叉单剂量口服左旋氨氯地平后,取血,采用LCMS-MS法测定血浆中药物浓度。结果单次口服左旋氨氯地平片(参比、受试)和左旋氨氯地平分散片(受试)5mg后的Gmax分别为(2.106±0.433)、(2.062±0.447)和(2.148±0.419)ng·mL^-1;tmax分别为(5.2±1.1)、(5.1±0.7)和(4.9±0.8)h;AUC0→120分别为(72.962±18.884)、(70.986±16.237)和(68.955±19.200)ng·h·mL^-1。受试制剂相对于参比制剂的生物利用度F分别为(98.7%±11.7%)和(95.2%±12.3%)。结论受试制剂苯磺酸左旋氨氯地平片(片及分散片)与参比制责4苯磺酸左旋氨氯地平片(施慧达)具有生物等效性。

Abstract:Objective To evaluate the bioequivalence of Levamlodipine Besylate tablets. Methods According to the cross over design , each volunteer was given a single oral dose of levamlodipine besylate tablets and then the plasma was obtained and determined by LC-MS-MS method. Results The main pharmacokinetic parameters of single dose of the three products were as follows : Cmax was (2.106±0.433), (2.062±0.447) and (2.148±0.419) ng·mL^-1, tmax was (5.2±1.1), (5.1±0.7) and (4. 9±0.8) h, AUC0→120 was (72. 962±18. 884), (70. 986±16. 237) and (68. 955±19. 200) ng h · mL^-1 for reference and test respectively. The relative bioavailability was (98. 7%±11.7%) and (95.2 %± 12.3 %), respectively. Conclusion The levamlodipine besylate tablets were bioequivalent.
