摘要
20名健康志愿者随机交叉单剂量口服加替沙星分散片(受试)和片剂(参比)400mg。用HPLC法检测血浆中加替沙星浓度,计算两种制剂的药动学参数并进行生物等效性评价。结果表明,受试制剂和参比制剂的主要药动学参数:AUC0→t为(35.51±4.87)和(36.38±4.50)μg·h·ml-1,cmax为(4.48±0.89)和(4.60±0.86)μg/ml,tmax为(0.85±0.38)和(0.94±0.38)h。加替沙星分散片的相对生物利用度为(98.5±15.4)%,表明两制剂具有生物等效性。
A single dosage 400mg by randomized cross-over design was used to investigate the pharmacokinetics and bioequivalence of gatifloxacin dispersible tablets (test preparation) and tablets (reference preparation) in 20 healthy volunteers after oral administration. The drug concentration in plasma was determined by HPLC. The main pharmacokinetic parameters of the test and reference preparations were as follows: AUC0→t(35.51±4.87) and (36.38±4.50) μg·h·ml^-1, Cmax (4.48±0.89) and (4.60±0.86) μg/ml, tmax (0.85±0.38) and (0.94±0.38)h, respectively. The relative bioavailability of the test preparation was (98.5±15.4) %. The result indicated that the two preparations are bioequivalent.
