摘要
作者用高效液相色谱法(HPLC)对苦参碱的大鼠药物动力学进行研究。其药时曲线符合2室开放模型,Ka为3.400/h,Ke为0.523/h,T1/2为3.971h。组织分布以肾脏最高,依次为脾、肺、脑、心、血;脏器药物浓度约在0.5h达峰值(肺在1h达峰值),与血药浓度一致,给药后48h仍可测得。药物主要经肾脏排泄。苦参碱的吸收完全而迅速,长期给药不存在积蓄。
The paper reports the pharmacokinetics of matrine in rats after oral administration. The concentrations in biological samples were detected by HPLC. The study shows that concentrations-time curve of matrine in blood conformed to a open 2-compartment model after 50mg/kg intragastric. Matrine obsorntion was rapid and complete,The peak of plasma and tissue level appeared in 0.5h. The distribution of matrine in rat’s tissues were as follows:highest in kidney, next in liver,spleen,lung,heart,brain,blood respectively,and were still can be detected after 48 hours.Urine was the main route of excretion. There was no accumulation in rats after 50mg/kg·intragastric qd-1×21d.
