【摘要】 目的研究依普利酮片单次及多次给药后的人体药动学。方法 30名健康志愿者分为三组,分别服用依普利酮片50、100、200 mg,其中100 mg组为多次给药组,连续给药7 d;采集24 h内动态血标本,高效液相色谱-串联质谱法测定血浆中依普利酮的浓度,并采用DAS 3.2.4软件对试验数据进行处理,计算药动学参数。结果单次口服50、100和200 mg依普利酮片的主要药动学参数ρmax分别为(723.20±203.59)、(1 212.47±249.52)、(2 053.32±394.06)μg·L-1,tmax分别为(1.8±0.7)、(2.1±0.9)、(1.9±0.4)h,t1/2分别为(2.6±0.4)、(3.0±0.7)、(3.4±1.3)h,AUC0-24h分别为(3 621.29±1 1 17.37)、(7 492.68±2 031.58)、(13 796.25±4 594.37)μg·h·L-1,AUC0-∞分别为(3 710.53±1 144.47)、(7 592.98±2 082.12)、(14 074.54±4 870.39)μg·h·L-1。多次给药100 mg后的药动学参数ρmax为(1 231.83±209.99)μg·L-1,tmax为(1.7±0.9)h,t1/2为(3.0±0.8)h,AUC0-24h为(7 043.78±1 818.54)μg·h·L-1,AUC0-∞为(7 131.65±1 840.84)μg·h·L-1。结论在50200 mg给药剂量范围内,依普利酮片在体内呈线性动力学特征。

【Abstract】 AIM To study the pharmacokinetics of the eplerenone tablets in Chinese healthy volunteers after single-dose and multiple-dose administrations.METHODS Thirty Chinese healthy volunteers were randomly divided to three groups and given eplerenon 50,100 and 200 mg once daily respectively.The multiple-dose group was administrated with eplerenon 100 mg once daily for 7 days.Intensive blood sampling was performed from thirty volunteers within 24 h after the single dosing and the last dose of the multiple dosing.HPLC-MS/MS method was developed and validated for the determination of eplerenone in plasma.The pharmacokinetic parameters were calculated by DAS 3.2.4 software.RESULTS After a single-dose of the different dose levels(50,100 and 200 mg),the main pharmacokinetics parameters of eplerenone were as follows,ρmax were(723.20±203.59),(1 212.47±249.52) and(2 053.32±394.06) μg·L-1,tmax were(1.8±0.7),(2.1±0.9) and(1.9±0.4) h;t1/2 were(2.6±0.4),(3.0±0.7) and(3.4±1.3) h,AUC0-24 hwere(3 621.29±1 117.37),(7 492.68±2 031.58) and(13 796.25±4 594.37) μg·h·L-1,AUC0-∞ were(3 710.53±1 144.47),(7 592.98±2 082.12) and(14 074.54±4 870.39) μg·h·L-1,respectively.The main pharmacokinetics parameters after 100 mg qd for seven days were as follows,ρmax was(1 231.83±209.99) μg·L-1,tmax(1.7±0.9) h,t1/2 was(3.0±0.8) h,AUC0-24 h was(7 043.78±1 818.54) μg·h·L-1,AUC0-∞ was(7 131.65±1 840.84) μg·h·L-1.CONCLUSION The pharmacokinetics parameters of eplerenone are linear in the dose range from 50-200 mg.
