摘要
10名健康受试者口服两种不同厂家生产的吉非罗齐胶囊,以高效液相色谱法(HPLC)测定其血药浓度经时过程,经“PKBP-N1”药动学程序计算表明,湘江制药厂生产的吉非罗齐胶囊与金晓制药厂生产的吉非罗齐胶囊的吸收半衰期t1/2ka分别为(042±019)和(049±028)h;消除半衰期t1/2分别为(148±084)和(126±045)h;达峰时间tmax分别为(145±037)和(160±078)h;达峰浓度cmax分别为(6188±1551)和(6151±1034)μg/mL;AUC0-∞分别为(21291±4716)和(19985±2491)μg·h/mL,以湘江制药厂生产的吉非罗齐胶囊为参比测得金晓制药厂生产的吉非罗齐胶囊的相对生物利用度为0939。经双单侧t检验法统计分析,表明两制剂间AUC无显著差异,两制剂具有生物等效性。
Bioavailability of gemfibrozil capsule(GC) was invesitgated in a crossover trial in 10 healthy volunteers after oral administration of 900 mg GC made by two manufacturers. Gemfibrozil plasma concentration was measured by HPLC method,pharmacokinetics parameters were estimated by pharmacokinetic program“PKBP-N 1”. The peak concentration of GC made by Xiang Giang manufacturer was (61 88±15 51)μg/mL,reached at (1 45±0 37)h,its elimination T 1/2 was (1 48±0 84)h。That made by Jin Xiao manufacturer was(61 51±10 34) μg/mL,reached at (1 26±0 45)h,its elimination T 1/2 was (1 60±0 78)h The relative bioavailabiligy of GC by Jin Xiao manufacturer was 0 939,wihich was estimated according to gemfibrozil capsule by Xiangjiang manufacturer. This two kinds of gemfibrozil were bioequivalent by two one-sidet test analysis.
