摘 要 目的:评价两种磷酸川芎嗪胶囊的生物等效性。方法:20名健康志愿者单剂量随机交叉口服两种磷酸川芎嗪胶囊100 mg, 采用HPLC法测定血浆中磷酸川芎嗪浓度;用DAS 2.0生物等效性软件计算主要药物动力学参数和生物等效性。结果:受试制剂和参比制剂其主要药动学参数t1/2分别为(0.82±0.37)和(0.97±0.42)h;Cmax分别为(2.12±0.62)和(1.96±0.52)mg•L-1,tmax分别为(0.33±0.09)和(0.36±0.10)h,AUC0-t分别为(1.84±0.38)和(1.75±0.39)mg•h•L-1,AUC0-∞分别为(1.86±0.40)和(1.78±0.39)mg•h•L-1,经方差分析和双单侧t检验,Cmax,tmax,AUC0-t,AUC0-∞均无统计学差异,受试制剂的相对生物利用度为105.5%。结论:两种磷酸川芎嗪胶囊在健康人体内具有生物等效性。

ABSTRACT Objective: To evaluate the bioequivalence of ligustrazine phosphate capsules in healthy volunteers. Method: Twenty healthy volunteers were randomly administrated with an oral single and crossover dose of 100 mg test or reference ligustrazine phosphate capsules. The plasma concentration of ligustrazine phosphate was measured by HPLC and the pharmacokinetic parameters were calculated using a DAS2.0 practical pharmacokinetics program.Result: The pharmacokinetic parameters for test and reference ligustrazine phosphate were as follows:t1/2were(0.82±0.37)vs.(0.97±0.42)h;Cmaxwere(2.12±0.62)vs.(1.96±0.52)mg•L-1;tmax(0.33±0.09)vs.(0.36±0.10)h,;AUC0-twere(1.84±0.38)vs.(1.75±0.39)mg•h•L-1;AUC0-∞were(1.86±0.40)vs.(1.78±0.39)mg•h•L-1,respectively.There were no significantly differences in main pharmacokinetic parameters between two treatments, The relative bioavailability of test ligustrazine phosphate capsules was 105.5%.Conclusion: The test capsules are bioequivalent to the reference capsules.
