摘要
目的建立奈韦拉平血药浓度的HPLC测定法,用于人体生物等效性研究。方法采用随机双交叉实验设计,20名健康受试者口服受试制剂和参比制剂200 mg,用HPLC法测定血浆中的奈韦拉平浓度。结果受试制剂和参比制剂的AUC0-168分别为(155.66±22.41)、(150.66±22.11)mg.h.L-1;AUC0-∞分别为(163.30±22.88)、(157.75±22.87)mg.h.L-1;Cmax分别为(2.52±0.31)和(2.60±0.48)mg.L-1;tmax分别为(3.1±0.7)和(3.0±0.7)h;t1/2分别为(38.12±2.23)、(36.79±5.06)h。受试制剂的相对生物利用度为103.6%±8.6%。结论经统计学分析,国产奈韦拉平片剂与进口奈韦拉平片剂具有生物等效性。
Objective To determine the pharmacokinetics and relative bioavailability of nevirapine tablets in Chinese healthy volunteers. Methods Twenty healthy male volunteers received 200 mg nevirapine tablets orally in a random crossover design, Drug concentrations in the plasma were determined by HPLC. Results The main pharmacokinetic parameters of the test tablet and reference tablet were as follows: AUC0-168 : ( 155.66±22. 41 )mg·h·L^-1 vs. (150.66±22.11) mg·h·L^-1; AUC0-∞: (163.30±22.88) mg·h·L^-1vs (157.75±22.87) mg·h·L^-1; Cmax: (2. 52±0.31) mg·L^-1vs (2.60±0.48) mg·L^-1; tmax: (3. 1±0. 7) hvs (3.0±0.7) h; t1/2 (38. 12±2. 23) hvs (36.79±5.06) h respectively. The relative bioavailability of the test tablet was 103.6%± 8. 6%. Conclusion The test tablet and reference tablet were bioequivalent.
