摘  要:目的:比较2种阿奇霉素分散片的人体生物等效性。方法:采用双制剂双周期自身交叉对照的方法,将22例健康男性受试音随机分为两组,口服阿奇霉案分散片受试制剂或参比制剂各1g。用HPLC-电化学检测法测定血浆中的阿奇霉素浓度,用DAS软件计算药动学参数,进行生物等效性评价。结果:阿奇霉素分散片受试制剂与参比制剂AUC_(0→132h)分别为(24,25±6.25)和(25.02±6.29)μg·h·mL^(-1);AUC_(0→∞)分别为(29.62±5.91)和(31.35±9.02)μg·h·mL^(-1);C_(max)分别为(1.18±0.17)和(1.18±0.21)μg·mL^(-1);T_(max)分别为(2.27±0.26)和(2.16±0.28)h;t_(1/2)分别为(39,89±9.36)和(42.27±9.62)h。与参比制剂比较,受试制剂相对生物利用度为(97.4±9.8)%。结论:口服阿奇霉素量试制剂和参比制剂生物等效。Objective:To assess the bioequivalence of two azithromycin dispersants. Methods: 22 healthy male volunteers were randomly assigned to one of two treatment groups. Each volunteer orally received a single dose of either test or reference azithromycin 1 gram and were then crossed-over. The plasma concentration of azithromycin was determined by HPLC with electrochemical detection. The pharmacokinetic parameters were assessed by DAS program. Results:The pharmacokinetic data of test and reference samples were as follows: AUC0-123h(24.25 ±6.25) vs. (25.02 ±6.29) μg·h·mL^-1; AUC0→∞ (29.62±5.91) vs. (31.35 ±9.02) μg·h·mL^-1; Cmax(1.18 ±0.17) vs. (1.18 ±0.21) μg·mL^-1; Tmax (2.27 ± 0. 26) vs. (2.16± 0. 28 ) h and t1/z (39.89 ± 9.36) vs. (42.27 ± 9.96) h. The relative bioavailability of the test sample was (97.4 ± 9.8) %. Conclusion : The test azithromycin dispersants were bioequivalent to the reference azithromycin.
