【摘要】 目的:研究多次口服奥美沙坦片在中国健康受试者体内的药代动力学。方法:10名受试者第1天和第8~14天,每天口服20 mg奥美沙坦片。采用HPLC-MS法测定给药后不同时间奥美沙坦的血药浓度。利用DAS Ver 2.0和SPSS13.0计算药动学参数和进行统计分析。结果:单次和多次口服20mg.奥美沙坦片达稳后,主要药代动力学参数:AUC0→t分别为(3356.3±865.9)、(4764.7±1700.5)ng·h/mL;AUC0→∞为(3778.2±922.9)、(4987.4±1679.7)ng·h/mL;Cmax为(295.4±70.1)、(550.0±157.3)ng/mL;tmax为(2.4±0.7)、(2.3±0.8)h;t1/2为(14.9±5.0)、(12.4±4.8)h。结论:中国健康受试者连续口服20 mg奥美沙坦片体内未见蓄积。
【Abstract】 AIM:To study the pharmacokinetics of olmesartan tablets after multiple oral dose adiminstration in Chinese healthy volunteers. METHODS:10 healthy volunteers were randomized to administer a single dose of olmesartan tablets at 20 mg on day 1 and day 8 to day 14.The concentrations of olmesartan in human plasma were determined by HPLC-MS.The main pharmaockinetic parameters were calculated and analyzed by DAS ver 2.0 and SPSS 13.0.RESULTS: The main pharmacokinetic parameters of olmesartan after oral a single dose and multiple-dose were as follow:AUC0→t(3356.3±865.9) and (4764.7±1700.5) ng·h/mL;AUC0→∞(3778.2±922.9) and (4987.4±1679.7) ng·h/mL;Cmax(295.4±70.1) and(550.0±157.3) ng/mL;tmax(2.4±0.7) and(2.3±0.8) h;t1/2(14.9±5.0) and(12.4±4.8) h,respectively.CONCLUSION:There is not cumulation of olmesartan in plasma after multiple dose of 20 mg.
