摘要: 目的 建立中国健康受试者口服法罗培南钠片的群体药代动力学(PPK)模型,研究法罗培南在中国健康人体内的药动学特点,评价法罗培南药动学的影响因素。方法 基于两个临床研究中心的健康受试者的临床研究资料,利用Phoenix NLME软件建立法罗培南的群体药代动力学模型,并用VPC验证法和自举法进行验证。结果 法罗培南在健康志愿者体内的药代动力学符合有滞后时间的一级消除动力学一房室模型,个体间变异符合指数模型。法罗培南清除率(CL/F)和分布容积(V/F)的群体典型值分别为 650.68 mL·h-1·kg-1 和 594.24 mL/kg。结论 饮食、性别对法罗培南的群体药代动力学参数有显著影响。所建立的PPK模型可以较好地估算服用法罗培南的的个体及群体药动学参数,为指导临床合理用药提供药动学参考。

Abstract: AIM: To establish the population pharmacokinetics (PPK) model of faropenem sodium tablets by oral administration in Chinese healthy adults, evaluate the pharmacokinetics characteristics of faropenem, and investigate the factors which could influence the pharmacokinetics of faropenem. METHODS: Based on the clinical research data of faropenem obtained from two clinical research centers using Chinese healthy adult volunteers, the population pharmacokinetics model was executed by using Phoenix NLME software, and validated by VPC method and bootstrap procedure. RESULTS: A one-compartment model with first-order elimination pharmacokinetics with lag time provided the best fit for faropenem. Inter-individual variability could be described by exponential model. The clearance (CL/F) and volume of distribution(V/F) were 650.68 mL·h-1·kg-1,594.24 mL/kg were 650.68 mL·h-1,594.24 mL/kg,respectively. CONCLUSION: The population pharmacokinetic parameters of faropenem were mainly offected by diet and gender. The established could estimate individual and population pharmacokinetic parameters of Chinese healthy adults, and drawn in favor of reasonable treatment regimen.
