摘要
目的:比较国产孟鲁司特钠分散片(受试制剂)与进口孟鲁司特钠片(参比制剂)的人体生物利用度。方法:20名健康受试者进行随机交叉试验,分别先后单次口服10mg两种孟鲁司特钠制剂,采用LC-MS法测定血浆中孟鲁司特浓度。结果:受试制剂和参比制剂的主要药动学参数分别为:t1/2(4.6±0.5)和(4.6±0.5)h,tmax(3.8±1.1)和(3.9±1.0)h,cmax(408.6±79.1)和(498.7±114.2)ng/ml,AUC0~24(3541±643.7)和(3143±436.8)ng.h.ml-1,AUC0~∞(3655±660.7)和(3260±450.4)ng.h.ml-1,结果表明主要药动学参数无显著性差异,受试制剂的相对生物利用度为(90.6±16.1)%。结论:国产孟鲁司特钠分散片与进口孟鲁司特钠片在健康人体内生物等效。
Objective:To compare the bioequivalence of domestic montelukast sodium dispersible tablets and imported montelukast sodium tablets in human body.Methods:A single oral dose of 10 mg test or reference montelukast was given to 20 volunteers in a randomized cross-over study,and the plasma concentration of montelukast was determined by liquid chromatography-tandem mass spectrometry(LC-MS).Results:The main pharmacokinetic parameters of test and reference preparations were as follows:t1/2(4.6±0.5) and(4.6±0.5) h,tmax(3.8±1.1) and(3.9±1.0) h,cmax(408.6±79.1) and(498.7±114.2) ng/ml,AUC0-24(3 541±643.7) and(3 143±436.8) ng.h.ml-1,AUC0-∞(3 655±660.7) and(3 260±450.4) ng.h.ml-1,respectively.There were no significant differences in main pharmacokinetic parameters between the two preparations,and the relative bioavailability of test preparation was(90.6±16.1)%.Conclusion:The domestic montelukast sodium dispersible tablets and imported montelukast sodium tablets are bioequivalent in healthy human.
