摘要: 目的 建立人体血浆中辛伐他汀的LC-MS MS测定方法, 研究辛伐他汀片在男性健康志愿者体内的药代动力学行为, 评价其生物利用度和生物等效性。方法 20 名健康成年男性志愿者采用随机分组、自身两周期双交叉对照试验设计, 单剂量口服参比制剂辛伐他汀片40 mg 后, 用LC-MS/MS 联用法测定血浆中药物浓度。结果 试验制剂和参比制剂的主要药代动力学参数:Tmax 分别为1.8±1.3 、2.10± 1.00 h;Cmax 分别为7.12± 1.61 、7.38±1.54 μg·L-1;AUC(0-24) 分别为30.50±11.25 、30.17±10.21 μ·L·h-1;t1/2 分别为3.90±0.78 、3.76±0.85 h 。以AUC(0-24) 计算的试验制剂的相对生物利用度为(101.2±7.8) %。结论 建立的分析方法准确灵敏, 测得的数据可靠, 统计学分析表明两种制剂生物等效。

Abstract: AIM: To establish a LC-MS MS method for determination of simvastatin in human plasma, and investigate the pharmacokinetics and bioequivalence of simvastatin tablet in Chinese healthy volunteers.METHODS: 20 male healthy volunteers were randomized to receive a single crossover oral dose of simvastatin reference tablet or domestic tablet.The concentration of simvastatin in plasma was determined by LC-MS/MS.RESULTS: The main pharmacokinetic parameters of test and reference simvastatin tablets were as following:Tmax:1.8 ±1.3,2.10 ±1.00 h, Cmax:7.12 ±1.61, 7.38 ± 1.54μg·L-1 , AUC(0-24):30.50 ±11.25, 30.17 ±10.21μg·h·L-1 , t1/2 :3.90 ±0.78, 3.76 ±0.85 h, respectively.F (0-24) was (101.2 ±7.8) %.CONCLUSION: The assay method is shown to be sensitive and accurate giving reliable results.The test tablet was bioequivalent to the reference tablet.
