单剂口服利巴韦林片在健康人体的药代动力学
The Chinese Journal of Clinical Pharmacology(2008)
Abstract
目的对国产利巴韦林片(抗病毒药)在健康中国男性受试者中空腹单剂量口服时的药代动力学特点进行评价。方法受试者单剂量口服利巴韦林300mg,用液相色谱-串联质谱法测定血浆中利巴韦林浓度,并用非房室模型计算药代动力学参数。结果药代动力学参数:AUC0-t为(5584.91±1659.34)ng.h.mL-1;AUC0-∞为(7166.33±2224.28)ng.h.mL-1;Cmax为(442.60±148.97)ng.mL-1;tmax为(1.40±1.20)h;t1/2为(22.93±6.38)h;Ke为(0.03±0.01)h-1;Vd为(1484.37±491.50);CL为(45.67±13.90)L.h-1。结论单剂口服利巴韦林在健康人体的代谢特征基本与文献报道参数[2-5]一致。
