摘要
目的 考察自制盐酸阿夫唑嗪缓释片及其市售制剂在健康人体的相对生物利用度及生物等效性.方法 采用双周期自身随机交叉试验设计.20名健康男性志愿者口服受试制剂或参比制剂,血药浓度采用液相色谱一串联质谱测定.结果 受试制剂及参比制剂的主要药动学参数为:Cmax分别为(16.8±5.9)和(17.5±5.7)ng/ml;Tmax分别为(4.1±1.5)和(4.5±1.2)h;t1/2分别为(8.5±1.7)和(8.6±1.8)h;AUC(0-48h)分别为(208±61)和(210±56)ng·h/m1;AUC(0-00)分别为(221±64)和(224±61)mg·h/MI;以AUC(o-48h)计算,受试制剂的相对生物利用度为(101.5±24.1)%.结论 受试制剂和参比制剂具有生物等效性.
Abstract
Objective To evaluate the relative bioavailability and bioequivalence between two kinds of alfuzosin hydrochloride sustained-release tablets. Methods The self-made sustained-release tablets or reference formulation were given orally to 20 healthy volunteers in a two-crossover test. Drug concentrations in plasma were determined by LC-MS-MS. Results The main pharmacokinetie parameters of the self-made sustained-release tablets and reference formulation were as follows: Cmaxwas (16.8 ±5.9)and (17.5 ±5.7) ng/ml; Tmax was (4.1 ±1.5) and (4.5 ± 1.2) h; t 1/2 was (8.5 ± 1.7) and(8.6 ± 1. 8) h,AUC(0-4sh) was (208 ±61 ) and (210 ±56) ng ·h/ml,AUC(0-∞) was (221 ± 64) and (224 ±61) mg ·h/ml. The relative bioavailability was (101.5 ± 24.1 ) %, Conclusion The test preparation is bioequivalent to the reference preparation.
