摘要: 目的 研究两种吡拉西坦片在健康中国人体的生物等效性。方法 20 名健康志愿者随机分为试验组和对照组, 采用双交叉设计和单剂量口服方式,HPLC 法测定血清中吡拉西坦浓度。经DAS2.0 统计软件处理, 计算主要药代动力学参数, 并进行两种片剂的生物等效性评价。结果 两种吡拉西坦片剂的t1/2为5.50 ±1.48 、4.29 ±1.00 h , Cmax 为21.47 ±6.27 、20.96 ±5.10 mg·L-1 , Tmax 为0.70 ±0.46 、0.66±0.36 h , AUC0 -24h 为93.44 ±16.61 、96.67 ±18.50 mg·h·L-1 。受试制剂的相对生物利用度为99.8%±22.7%。结论 两种吡拉西坦片剂具有生物等效性。

Abstract: AIM: To study the bioequivalence of piracetam tablets in Chinese healthy volunteers.METHODS: Twenty volunteers were randomly divided into two groups (test and reference), with double cross-over design and single-dose oral administration.The concentration of piracetam in serum was determined by HPLC.The main pharmacokinetic parameters were calculated and the bioequivalencewas evaluated with DAS2.0 practical pharmacokinetics program.RESULTS: The pharmacokinetic parameters of piracetam tablets were as follows:t1/2 were 5.50 ±1.48 and 4.29 ±1.00 h , Cmax were 21.47 ±6.27 and 20.96 ±5.10 mg·L-1 , Tmax were 0.70 ±0.46 and 0.66 ±0.36 h , AUC0-24h were 93.44 ±16.61 and 96.67 ±18.50 mg·h·L-1.The relative bioavailability of the test preparation was 99.8%±22.7%.CONCLUSION: The test and reference preparations were bioequivalent and may be prescribed interchangeably.
