PBPK模型搭建

  • 收集药物信息
    1) 理化性质参数(logP, pKa等)
    2) 制剂信息(混悬、速释、缓控等)

  • 构建处置模型(Disposition)
    1) 通过静注后人的PK数据拟合
    2) 或通过体外及动物资料预测

  • 用GastroPlus搭建模型
    1) 用GastroPlus的吸收模型(ACAT),连接处置模型
    2) 用该药其它制剂的 PK 资料优化不确定的参数

模型验证

  • 用该药不同剂量、不同剂型等 PK 数据验证(Validate)搭建的模型,验证该模型预测不同 PK 数据的结果

模型应用

验证后的模型可用于
– 鉴定限制生物利用度的关键性因素,指导后续制剂研发;
– 模拟不同给药方案下 PK 的变化;
– 建立体内外相关性 IVIVC,确定最反映体内溶出的体外溶出条件
– 指导体外溶出标准的制定;
– 模拟虚拟生物等效性试验;
– 建立 PK-PD 模型,评估不同剂型、剂量、给药方案下,药效的变化;
– 药物药物相互作用 DDI;
