摘要: 目的: 研究甘草连续给药 7 d 对环孢素在大鼠体内的药代动力学影响。方法: 12只大鼠随机分为生理盐水对照组和甘草实验组,甘草实验组予甘草提取物(0.5 g/kg,1次/d)连续给药 7 d,第 8天晨两组均予环孢素灌胃给药后按时间点连续采样,采用荧光偏振免疫分析法测定环孢素的血药浓度,计算并比较主要药动学参数。结果: 对照组和实验组的环孢素主要药动学参数Cmax、tmax、t1/2、AUC0-48 h、AUC0-∞、平均滞留时间(MRT)、药物清除率(CL/F)、表观分布面积(V/F)差异均无统计学意义(P>0.05)。结论: 甘草连续给药 7 d 后不影响环孢素在大鼠体内的药代动力学。

Abstract: AIM: To study the effect of licorice extract on cyclosporine pharmacokinetics in rats. METHODS: Experimental rats were randomly divided into the control and test groups which were administrated respectively with normal saline and extract of licorice. After pretreated with extract of licorice (0.5 g/kg, once daily) for 7 days, cyclosporine was given to the rats by intragastric administration in the 8th day. Whole blood cyclosporine concentrations were measured by a fluorescence polarization immunoassay (FPIA). Pharmacokinetic parameters between two groups were compared. RESULTS: There were no significant differences between the two groups in the main pharmacokinetic parameters of cyclosporine, such as Cmax,tmax,t1/ 2,AUC0-48 h,AUC0-∞,MRT,CL/F,V/F(P>0.05). CONCLUSION: The results suggest that treatment with extract of licorice (0.5 g/kg, once daily) for 7 days did not affect the pharmacokinetics of cyclosporine in rats.
