摘  要:目的评价2种司帕沙星胶囊在健康人体的药代动力学和生物等效性。方法 20名男性健康志愿者随机分为2组,用开放的双周期交叉试验设计,单次口服试验药物或参比药物司帕沙星胶囊0.2 g后,用HPLC内标法测定血药浓度。用DAS2.1软件计算药代动力学参数和统计学分析。结果试验药物和参比药物的体内药动学参数如下:Cmax分别为(1.23±0.23),(1.23±0.23)μg.mL-1,tmax分别为(3.70±1.56),(3.85±1.53)h,t1/2分别为(19.98±5.04),(19.11±5.22)h,AUC0-72 h分别为(27.61±4.89),(26.53±5.84)μg.h.mL-1;受试药物司帕沙星胶囊的相对生物利用度为(106.3±16.7)%。结论试验药物和参比药物在健康人体的处置过程基本一致,具有生物等效性。Objective To study the pharmacokinetics and bioequivalence of sparfloxacin capsules in healthy human. Methods In a randomized and cross - over study, 20 healthy volunteers were divided into two groups and orally given 0. 2 g sparfloxacin capsules (test or reference). A sensitive and rapid HPLC method was developed to determine the metformin plasma concentration. The plasma concentration - time curves and the bioequivalence of reference ande test preparation were analyzed by DAS2. 1 software. Results The main pharmaeokinetic parameters were as follows, Cmax were ( 1.23 ± 0.23) , ( 1.23 ± 0. 23) ug . mL-1 ,tmax were(3.70 ± 1.56), (3.85 ± 1.53) h,t1/2 (19.98 ± 5.04), (19. 11 ±5.22)h, AUC0-72h were (27.61 ±4. 89) ,(26.53 ±5.84) ug . h . mL-1, respectively. The relative bioavailability of sparfloxaein capsules test was( 106.3 ± 16.7) %. Conclusion The results demonstrated that the two preparations were bioequivalent
