摘要:
目的:研究扎莱普隆片在20名健康志愿者体内的药代动力学特征及相对生物利用度.方法:20名健康男性志愿者采用随机交叉给药方案,分别单剂量口服的扎莱普隆片10mg和对照胶囊,用液-液相萃取后、HPLC-ESI-MS分析方法对血药浓度进行测定,计算两者的药代动力学参数及相对生物利用度.结果:试验片和对照胶囊的血药浓度水平一致.其主要药代动力学参数t1/2分别为1.17±0.19 h和1.14±0.12h;tmax分别为0.83±0.12h和0.91±0.12h,Cmax分别为28.47±2.62μg@l-1和28.12±3.44μg@l-1,AUC0-8分别为52.83±4.81μg.h.l-1和54.92±8.83μg@h@l-1,两制剂的药代动力学参数相近.用面积估算的扎莱普隆片的相对生物利用度F0-8为(98.3±16.5)%,F0-∞为(98.0±16.4)%.结论:扎莱普隆片和对照胶囊的AUC、Cmax经方差分析和双单侧t-检验表明:两制剂生物等效;tmax经非参数法检验,表明两种制剂无显著性差别(P>0.05).
