摘要: 目的: 研究体内克拉维酸钾 -阿莫西林两组份的主要药动学参数与服药剂量间的线性关系。 方法: 15 名健康受试者随机分成 5 个剂量组, 服药后采用高效液相-紫外检测法测定不同时间点的药物浓度, 经 3p97 软件处理, 求出其主要药动学参数AUC 和 cmax, 并将其 AUC 和 cmax 分别对服药剂量作线性回归。结果: 克拉维酸钾主要药动学参数AUC和 cmax 与其服药剂量回归方程分别为 Y =2.0895X+0.4438(r =0.9915)和 Y =0.9397X +0.1796(r =0.9922)。阿莫西林主要药动学参数 AUC 和 cmax 与其服药剂量回归方程分别为 Y=4.8795X+2.4794(r=0.9988)和Y =1.7276X+1.4832(r =0.9935)。结论: 克拉维酸钾-阿莫西林两组份在体内的主要药动学参数均与其服药剂量呈良好的线性关系。

Abstract: AIM: To study the linear relationship be-tween pharmacokinetic parameters and doses about potas-sium clavulanic acid (CAV)and amoxicillin (AMX). METHODS: 15 healthy male volunteers were randomly divided into 5 dose-groups.The plasma concentration of CAV and AMX was determined by high performance liq-uid chromatography (HPLC)method.The pharmacokinet-ic parameters obtained with 3p97 soft were regressed to corresponding dose. RESULTS: The regression equations of AUC and cmax to dose about CAV were Y =2.0895X +0.4438 (r =0.9915)and Y =0.9397X +0.1796 (r =0.9922), respectively. The regression equations of AUC and cmax to dose about AMX were Y =4.8795X + 2.4794(r =0.9988)and Y =1.7276X +1.4832 (r = 0.9935), respectively. CONCLUSION: There is good linear relationship between pharmacokinetic parameters and doses about CAV and AMX.
