Rational dosing guidelines for drugs in pediatrics are urgently needed. To develop these guidelines, we use population pharmacokinetic-pharmacodynamic (PK-PD) modeling and simulation by: (i) optimization of clinical trial designs based on preliminary data; (ii) development and internal validation of population PK-PD models using sparse data; (iii) external validation using independent data; and (iv) prospective clinical evaluation. Optimized dosing regimens for specific drugs may then serve as a basis to develop dosing guidelines for existing or newly developed drugs with similar disposition and/or effect. In addition to modeling of drug disposition (PK) pathways, we emphasize the need for modeling of effect (PD) pathways and the use of a multidisciplinary infrastructure for data-sharing.
迫切需要制定儿科药物的合理给药指南。为制定这些指南,我们采用群体药代动力学-药效学(PK-PD)建模与模拟,方法如下:(i)根据初步数据优化临床试验设计;(ii)使用稀疏数据开发群体PK-PD模型并进行内部验证;(iii)使用独立数据进行外部验证;(iv)进行前瞻性临床评估。然后,特定药物的优化给药方案可作为为具有相似处置和/或效应的现有或新开发药物制定给药指南的基础。除了对药物处置(PK)途径进行建模外,我们还强调需要对效应(PD)途径进行建模,并使用多学科基础设施进行数据共享。
