摘 要
儿童用药的安全性与有效性是全球公共卫生领域的重要议题，鉴于儿童生理特点与成人显著不同，传统药物研发和评价方法难以满足其特殊需求。本研究旨在系统评估儿童用药的安全性和有效性，并探索适合儿童的药物评价体系。研究采用多中心、前瞻性队列设计，结合药代动力学和药效学分析，选取了10种常用儿科药物进行为期两年的跟踪调查，涉及3000余名2月至12岁儿童。结果表明，部分药物在儿童体内的代谢特征与成人存在显著差异，常规剂量可能导致不良反应风险增加或疗效不足。通过建立基于体重和年龄的个体化给药模型，有效降低了不良事件发生率，并显著提升了治疗效果。此外，本研究首次提出将生物标志物纳入儿童药物安全性评价体系，为精准用药提供了新思路。总体而言，该研究不仅填补了儿童用药评价领域的数据空白，还为相关政策制定和临床实践优化提供了科学依据。关键词：儿童用药; 安全性评价; 个体化给药模型; 药代动力学; 生物标志物
Abstract
The safety and efficacy of pediatric medications represent a critical issue in global public health, as the physiological characteristics of children differ significantly from those of adults, making traditional drug development and evaluation methods insufficient to meet their unique needs. This study aims to systematically assess the safety and efficacy of pediatric medications and explore an appropriate drug evaluation system for children. A multicenter, prospective cohort design was employed, integrating pharmacokinetic and pharmacodynamic analyses, to conduct a two-year follow-up investigation on ten commonly used pediatric drugs among over 3,000 children aged 2 months to 12 years. The findings indicate that the me tabolic profiles of some drugs in children differ substantially from those in adults, and routine dosages may increase the risk of adverse reactions or result in insufficient therapeutic effects. By establishing an individualized dosing model based on weight and age, the incidence of adverse events was effectively reduced, and treatment outcomes were significantly improved. Furthermore, this study is the first to propose incorporating biomarkers into the safety evaluation system for pediatric drugs, offering new insights into precision medication. Overall, this research not only fills a data gap in pediatric drug evaluation but also provides a scientific basis for policy formulation and the optimization of clinical practices.Key words:Children's Medication; Safety Evaluation; Individualized Dosing Model; Pharmacokinetics; Biomarker
