摘 要:目的评价国产和进口舍曲林片在中国人群中的生物等效性。方法采用液相色谱-质谱联用法测定18名健康受试者po100 mg舍曲林片后血浆中的舍曲林浓度。采用统计软件计算药动学参数,并评价其生物等效性。结果国产舍曲林片和进口片的药动学参数AUC0-100分别为(836.73±427.15)和(839.55±423.66)μg.h.L-1,实测mρax为(27.71±9.67)和(26.34±8.21)μg.L-1,实测tm ax为(5.78±1.11)和(5.83±1.20)h,MRT为(31.73±3.59)和(32.83±3.89)h,t1/2为(28.89±6.32)和(31.13±9.63)h。国产舍曲林片和进口片的相对生物利用度为(99.52±8.87)%。结论经统计学分析,国产舍曲林片和进口片具有生物等效性。OBJECTIVE To evaluate the bioequivalence of domestic sertraline tablets and imported tablets. METHODS A single oral dose of 100 mg domestic or imported sertraline tablets was given to 18 healthy volunteers in a randomized crossover study. The concentrations of sertraline were determined by HPLC-MS method. RESULTS The main pharmacokinetic parameters of two products were as follows:AUC0-100 (836. 73 ±427.15) and (839. 55 ±423.66) μg · h · L^-1 ,pmax (27. 71 ±9. 67) and (26. 34 ±8.21 ) μg · L^-1 ,tmax(5.78 ± 1. 11) and (5.83 ± 1.20)h,MRT (31.73 ± 3.59) and (32. 83 ±3.89)h,t1/2(28. 89 ±6. 32) and (31.13 ±9.63) h, respectively. The relative bioavailability of domestic sertraline tablet to imported tablet was (99.52± 8.87 ) %. There were no signit: icant differences on the pharmacokinetic parameters between the two preparations ( P 〉 0. 05 ). CONCLUSION The results of stastical analysis demonstrated that the two preparations were bioequivalent.
