摘要
目的比较正常和17α-乙炔基雌二醇诱导的胆汁淤积性肝损伤大鼠体内芍药苷的药代动力学过程的差异。方法采用LC-MS/MS法检测给药后不同时间点大鼠血浆样本中芍药苷的含量,DAS 2.0软件测算两组的药代动力学参数,并进行统计学分析。结果与正常大鼠相比,胆汁淤积性肝损伤发生后,芍药苷的t_(1/2Z)、MRT_(0~∞)、AUC和V_(z)/F明显增加,而CL_(z)/F显著降低。结论与正常大鼠相比,胆汁淤积模型大鼠体内芍药苷的浓度更高、消除速度更缓慢。
Objective To compare the pharmacokinetic process of paeoniflorin in normal rats and rats with 17α-ethinylestradiol-induced cholestatic liver injury.Methods The content of paeoniflorin in the rat plasma samples at different time points after the administration was detected by LC-MS/MS.The pharmacokinetic parameters of the two groups were analyzed by DAS 2.0 software.Results The pharmacokinetic behaviors of rats changed after the development of cholestatic liver injury as compared to those of normal rats.Specifically,t_(1/2Z),MRT_(0~∞),AUC and V_(z)/F of paeoniflorin were obviously increased,while CL_(z)/F was greatly decreased.Conclusion Compared with the normal rats,the concentration of paeoniflorin is higher and the elimination rate slower in the cholestatic model rats.
