摘要: 目的 对中枢镇静类儿科药物的药动/药效学(PK/PD)模型进行综述,为定量药理学模型在儿科药物研发上提供参考。方法 对近20年中枢镇静类儿科药物定量药理学相关文献进行整理、分析、归纳。结果 清除率是确定不同年龄段的儿科人群用药剂量的重要参数,也是PK/PD模型模拟的关键拟合参数,且清除率变化与儿科人群的体重变化呈现良好的相关性。结论 儿科患者具有明显的发育学特征,尤其在作用于中枢系统的药物上需要更密切地关注。基于儿科人群与成人之间的生理药动学差异、药物暴露-效应差异以及儿科人群临床试验的实施特点,PK/PD模型有助于儿科患者个体化治疗。

Abstract: Objective To summarize the pharmacokinetic/pharmacodynamic (PK/PD) models of central sedative pediatric drugs in order to provide references for quantitative pharmacological models in pediatric drug research and development. Methods The related literature of quantitative pharmacology of central sedative pediatric drugs were collected, analyzed, and summarized in the recent 20 years. Results Clearance was a key parameter to fit the PK/PD models, so it could be critical for determining the doses for pediatrics at different ages. Moreover, there was also a good correlation between the clearance and body weight in pediatric population. Conclusion A close attention should be paid on the physiological characteristics of pediatric patients, especially for investigating drugs acting on the central nervous system. Based on the physiological pharmacokinetic differences and drug exposure-response differences between pediatrics and adults, and considering the practice points of pediatric clinical trials, the PK/PD model supports the pediatric individualized treatment with central sedation drugs.

Key words: pediatric population, pharmacokinetic/pharmacodynamic model, data extrapolation, central sedation, dose regimen, individualized treatment
