摘要
目的:研究头孢丙烯颗粒在健康人体内的药动学和相对生物利用度,并与市售头孢丙烯片进行生物等效性评价。方法:18名男性健康受试者双周期随机交叉单剂量口服500mg头孢丙烯颗粒剂和片剂,两次试验间隔为1周,采用HPLC法测定血浆中头孢丙烯的浓度。结果:受试制剂与参比制剂的体内过程基本一致,其主要药动学参数Cmax分别为(10.36±1.27)和(8.90±0.93)μg/mL;tmax分别为(1.07±O.30)和(2.19±0.81)h;t1/2分别为(1.55±0.17)和(1.47±0.22)h;AUC0-10分别为(31.39±5.17)和(30.21±4.77)μg·h·mL^-1。结论:统计分析结果表明两种制剂具有生物等效性,头孢丙烯颗粒的相对生物利用度为(104.30±9.94)%。
Objective:To evaluate the pharmacokinetics and relative bioavailability of cefprozil granules in healthy volunteers. Methods: Eighteen heahhy male volunteers were randomized into two groups. A single oral dose of 500 mg cefprozil granules(test) or tablets(reference) were given respectively to the volunteers according to a randomized two-way cross-over study design. The washout period was one week. The plasma concentrations of cefprozil were determined by HPLC method. Results: The process in vivo of the test and reference preparations were essentially identical. The main pharmaeokinetic parameters of the test and reference preparations were as follows:cmax(10. 36±1. 27) and (8. 90±0. 93) μg/mL,tmax (1.07±0.30) and (2.19±0.81) h,t1/2(1.55±0.17) and (1.47±0.22) h, AUC0-10(31.39±5. 17)and (30.21±4.77) μg · h · mL^- 1 , respectively. Conclusion:The results of statistical analysis show that two preparations are of bioequivalence. The relative bioavailability of cefprozil granules is (104.30±9.94)%.
