摘要
目的:研究马来酸替加色罗分散片的人体生物等效性。方法:22名健康男性志愿者随机交叉单剂量口服马来酸替加色罗分散片(受试制荆)和马来酸替加色罗片(参比制剂)6mg,采用LC/MS/MS法测定人血浆中药物浓度。结果:受试制剂和参比制剂的tmax分别为(0.86±0.22)、(1.01±0.24)h Cmax分别为(2.21±0.69)、(2.05±0.64)ng·mL^-1,AUC0~17分别为(6.35±2.48)和(6.47±1.99)ng·h·mL^-1,AUC0-∞分别为(6.69±2.59)、(6.70±2.03)ng·h·mL^-1。受试制剂相对于参比制剂的生物利用度为(98.2±22.1)%。结论:两种制剂具有生物等效性。
OBJECTIVE: To study the bioequivalence of tegaserod maleate dispersible tablets in healthy volunteers. METHODS:A single oral dose of 6mg test or reference preparations of tegaserod maleate was given to 22 healthy volunteers in a randomized crossover study.The plasma concentrations of tegaserod were determined by LC/MS/MS assay.RESULTS:The main pharmacokinetic parameters of test and reference products were as follows: tmax(0.86±0.22) and(1.01 ± 0.24) h; Cmax (2.21 ±0.69) and (2.05±0.64) ng·mL^-1AUC0-17(6.35±2.48) and(6.47±1.99)ng·h·mL^-1 AUC0-∞(6.69±2.59) and (6.70± 2.03)ng ·h · mL^ -1,respectively.The relative bioavailability of test to reference preparation was(98.2± 22.1) % .CONCLUSION:The reference preparation and the test preparation are bioequivalent.
