摘要
研究氟氧头孢在老年腹腔感染患者体内的药物动力学 ,并与健康志愿者比较。 6例健康志愿者和 6例老年腹腔感染患者分别静脉滴注氟氧头孢钠 1g,采用 HPL C法测定血浆和尿中药物浓度 ,主要药物动力学参数分别为t1 / 2 -(1.18± 0 .2 0 ) h和 (1.93± 0 .3 1) h,Cls-(16.63± 1.73 ) L/h和 (10 .95± 2 .65 ) L/h,AUC-(63 .47± 4.5 7) h·μg·ml-1和 (99.45± 2 0 .2 3 ) h·μg· ml-1。氟氧头孢药 -时曲线符合二室开放模型 ,主要代谢方式是经肾脏原形排出。与健康志愿者相比 。
The pharmacokinetics of flomoxef in 6 healthy volunteers and 6 elder patients with abdominal infection diseases after infusion of 1 g flomoxef sodium injection were studied. Flomoxef concentrations in plasma and urine were determined by HPLC. The main pharmacokinetic parameters of flomoxef in healthy volunteers and elder patients were t 1/2 -(1.18±0.20) h and (1.93±0.31) h, Cls -(16.63± 1.73) L·h -1 and (10.95±2.65) L·h -1 , AUC -(63.47±4.57) h·μg·ml -1 and (99.45±20.23) h·μg·ml -1 ,respectively. Drug concentrations time profile of flomoxef was fitted to two compartment open pharmacokinetic model. Flomoxef was mainly excreted in unchanged form through kidney. Elder patients had prolonged t 1/2 , lowered Cls and elevated AUC in comparison with healthy volunteers. The results showed that flomoxef was metabolized and eliminated more slowly in the former than in the latter.
