磷酸川芎嗪滴丸药物动力学研究

目的: 探讨磷酸川芎嗪滴丸药物动力学特征。方法: 20名健康志愿者,单剂量口服磷酸川芎嗪滴丸200mg,采用高效液相色谱法(HPLC)测定血清中药物的浓度,DAS2.0程序计算药代动力学参数。结果: 磷酸川芎嗪滴丸主要药代动力学参数:Ka为(0.151±0.144) min,T_max为(40.5±15.5) min,C_max为(1.7±0.3)μg/ml,t_1/2β为(67.7±3.2) min,CL/F为(0.017±0.004) L·min-1·kg-1,AUC_0-300min为(181.5±40.3)μg·min-1·ml-1,AUC_(0-∞)为(209.6±46.6)μg·min-1·ml-1。结论: 单剂量口服磷酸川芎嗪滴丸200mg最佳房室模型为二室模型。

Study on the pharmacokinetics of ligustrazine phosphate dripping pills in healthy volunteers

Objective: To studdy the pharmacokinetics of ligustrazine phosphate dripping pills.Methods: Twenty healthy volunteers were given a single oral dose of 200 mg ligustrazine phosphate dripping pills.The serum concentrations of ligustrazine were determined by high performance liquid chromatogram (HPLC).The pharmacokinetic parameters were calculated with DAS2.0 practical pharmacokinetics program.Results: The main pharmacokinetics parameters of ligustrazine phosphate dripping pills were as follows:Ka was (0.151±0.144) min, T_max was (40.5±15.5) min, C_max was (1.7±0.3) μg/ml, t_1/2β was (67.7±3.2) min, CL/F was (0.017±0.004) L·min-1·kg-1, AUC 0-300 min was (181.5±40.3) μg·min-1·ml-1 and AUC_(0-∞) was (209.6±46.6) μg·min-1·ml-1, respectively.Conclusions: The preparation fits the two-compartment model best.
