摘    要:目的:研究氯沙坦钾胶囊及其片剂在健康人体内的药动学特征,并评价两种制剂间的生物等效性.方法:20名健康男性志愿受试者随机交叉单剂量口服试验制剂和参比制剂50 mg,清洗期1周,LC-MS/MS法测定血浆氯沙坦和代谢物氯沙坦羧酸(E-3174)浓度.药代参数的计算与统计分析使用DAS2.0软件.结果:口服试验制剂和参比制剂后,受试者的氯沙坦和E-3174主要药代动力学参数如下:氯沙坦Cmax分别为(183.83±91.30),(176.45±93.97) μg·L-1;AUC0-t分别为(333.18±105.00),( 323.75±101.92) μg·h·L1;AUC0-∞分别为(344.88±104.15),(341.32±106.13) μg·h·-1;t1/2分别为(1.84±0.52),(1.99±0.60)h;tmax分别为(0.70±0.22),(0.98±0.62)h.E-3174 Cmax分别为(344.85±114.33),(329.95±106.42) μg·L-1;AUC0-t分别为(2 445.09±608.97),(2 332.54±564.72) μg·h·L-1;AUC0-∞分别为(2 503.45±612.62),(2 390.92±567.03) μg·h·L-1;t1/2分别为(4.17±0.49),(4.13±0.66)h;tmax分别为(3.14±0.72),(3.39±0.96)h.试验制剂氯沙坦钾胶囊中氯沙坦和E-3174相对生物利用度分别为( 104.9±20.7)%和(105.2±12.1)%.结论:本试验采用的氯沙坦钾胶囊和氯沙坦钾片为生物等效制剂.

Abstract:Objective: To evaluate the pharmacokinetics and the bioequivalence between losartan potassium capsule and tablet in healthy volunteers.Methods: It was designed as randomized,two-way crossover study with 1 week washout interval,and blood samples were collected after administration with a single oral dose 50 mg of test and reference preparation in 20 healthy male volunteers,the plasma concentrations of losartan and E-3174 were determined by LC-MS/MS.The pharmacokinetics parameters were calculated and statistically analyzed by DAS2.0 software.Results: The pharmacokinetic parameters of losartan and E-3174 of test and reference preparation were as follows: for losartan,Cmaxwere(183.83±91.30),(176.45±93.97) μg.L-1;AUC0-twere(333.18±105.00),(323.75±101.92) μg.h.L-1;AUC0-∞ were(344.88±104.15),(341.32±106.13) μg.h.L-1;t1/2 were(1.84±0.52),(1.99±0.60) h;tmax were(0.70±0.22),(0.98±0.62) h,respectively.For E-3174,Cmax were(344.85±114.33),(329.95±106.42) μg.L-1;AUC0-t were(2 445.09±608.97),(2 332.54±564.72) μg.h.L-1;AUC0-∞ were(2 503.45±612.62),(2 390.92±567.03) μg.h.L-1;t1/2were(4.17±0.49),(4.13±0.66) h;tmax were(3.14±0.72),(3.39±0.96) h,respectively.The relative bioavailability of losartan and E-3174 of the test preparation were(104.9±20.7) % and(105.2±12.1)%.Conclusion: The losartan potassium capsule and tablet were bioequivalent.
