摘要: 目的: 研究甘草对卡马西平及其代谢产物10,11-环氧卡马西平在大鼠体内的药代动力学影响。方法: 12只实验大鼠随机分为生理盐水对照组和甘草实验组,甘草提取物(0.5 g/kg,1次/d)连续给药 7 d 后,卡马西平灌胃给药后按时间点连续采样,采用HPLC法测定卡马西平及其代谢产物。计算并比较主要药动学参数。结果: 对照组和实验组的卡马西平主要药动学参数Cmax、tmax、t1/2、AUC0→24 h、AUC0→∞、MRT差异均无统计学意义(P>0.05),而10,11-环氧卡马西平的Cmax、tmax和AUC0→24 h同样无统计学意义(P>0.05)。结论: 甘草连续给药7 d后不影响卡马西平在大鼠体内的药代动力学。

Abstract: AIM: To study the effect of licorice on carbamazepine and carbamazepine-10,11-epoxide pharmacokinetics in rats. METHODS: Experimental rats were randomly divided into the control and test group, which was administrated respectively with normal saline and extract of licorice.After pretreated with extract of licorice (0.5 g/kg, q.d.) for 7 days, carbamazepine was given to the rats by intragastric administration.The plasma concentrations of carbamazepine and carbamazepine-10,11-epoxide were determined by HPLC. Pharmacokinetic parameters between two groups were compared. RESULTS: There were no significant differences between the two groups in the main pharmacokinetic parameters of carbamazepine, such as Cmax, tmax, t1/2, AUC0→24 h, AUC0→∞, MRT (P>0.05),the same as carbamazepine-10,11-epoxide of Cmax, tmax and AUC0→24 h.CONCLUSION: The results suggest that treatment with extract of licorice (0.5 g/kg, q.d.) for 7 days did not affect the pharmacokinetics of carbamazepine in rats.
