摘要
目的:建立测定人血浆中头孢丙烯浓度的HPLC法,并应用于健康人体药动学研究。方法:10名男性健康志愿者单剂量口服500mg头孢丙烯片,以HPLC法测定血浆中头孢丙烯浓度,采用非房室模型法计算药动学参数。结果:主要的药动学参数如下:cmax(8.64±1.00)μg/mL,tmax(2.00±0.85)h,t1/2(1.47±0.27)h,MRT(2.88±0.49)h,C1/F(17.964±2.50)L/h,AUC0~10(28.05±4.60)μg·h·mL^-1和AUC0-∞(2842±4.75)μg·h·mL^-1结论:本方法的准确度、灵敏度、专属性及重现性等符合生物样品的分析要求,适用于头孢丙烯片的人体药动学研究。
Objective: To establish a HPLC method to determine the plasma concentrations of cefprozil and study its pharmacokinetics in healthy volunteers. Methods: Ten male healthy volunteers received a single oral dose of 500 mg of cefprozil tablets. The plasma concentrations of cefprozil were determined by HPLC method. The pharmacokinetic parameters were calculated by non-compartment model. Results: The main pharmacokinetic parameters of cefprozil were cmax (8.64±1.00) μg/mL, tmax(2.00±0.85) h,t12 (1.47±0.27) h,MRT(2, 88±0.49) h,C1/F (17.96±2.50) L/h,AUC0-10 (28.05±4.60) μg· h · mL^-1 and AUC0-∞ (28.42±4.75) μg· h · mL^-1. Conclusion:This method is proved to be accurate, sensitive, specific and reproducible for the determination of cefprozil in human plasma. It is suitable for pharmacokinetic study of cefprozil tablets in healthy volunteers.
