摘要: 目的 研究甲磺酸培氟沙星人体内药代动力学,为该药的临床评价提供依据。方法 10名健康志愿者单剂量口服400 mg甲磺酸培氟沙星后,采用HPLC法测定血药浓度,并拟合药代动力学参数。结果 8名受试者药时曲线为二室模型,2名为-室模型,平均达峰时问为1.19+0.48h, 消除半衰期为11.61±2.53 h,药时曲线下面积51.82士17.10μg·h.ml-1,吸收速率常数个体差异明显(1.69~9.23h-1)。结论 甲磺酸培氟沙星吸收迅速,半衰期长,体内分布广,有利于深部组织感染的治疗。

Abstract: Aim Pefloxacin mesylate(PM) was given orally in a single dose of 400mg to 10 healthy adult volunteers to observe its pharmacokinetics. Methods The assay of plasma PM concentration. by HPLC method revealed that the concentration-time data in 8 subjects were fit for a two-compartment model and in 2 subjects for a one-compartment model. Results The average Tmax 1. 19+0.48h,elimination T1/2 11.61±±2.53 h and AUC 51.82士17.10 μg h·ml-1. A considerable intersubject variability was noted in the constants of absorption rate. Pefloxacin esylate was rapidly absorbed in gastrointestinal tract, and was widely distributed, which indicated that it was of benefit to the therapy of deep tissue infections.
