使用PBPK建模研究了与甲基酸盐 (MTX) 的药物相互作用. 与利芬素或费布斯塔特同时使用显著增加了MTX暴露,突出显示了载体介导药物相互作用的重要性.
科学领域:
- 药理学 药理学是指药理学的学科.
- 药物代谢和运输 药物代谢和运输
- 计算生物学 计算生物学
背景情况:
- 甲甲酸 (MTX) 是一种重要的抗叶酸药物,用于治疗类风湿性关节炎和癌症.
- 药物载体在MTX的药理动力学中起着至关重要的作用,可以调解药物相互作用 (DDI).
- 基于生理学的药理动力学 (PBPK) 建模提供了一种机械方法来预测DDI.
研究的目的:
- 通过使用PBPK建模,通过药物运输体介导的MTXDDI进行定量评估.
- 为了研究利芬素 (RFP) 和费布克索斯塔特 (FBX) 对MTX药理学的影响.
- 用临床数据验证PBPK模型,用于预测MTX DDIs.
主要方法:
- 使用体外和体外数据开发了MTX,RFP和FBX的PBPK模型.
- 在健康志愿者中进行了一项随机交叉临床研究.
- 评估了RFP (OATP抑制剂) 和FBX (BCRP抑制剂) 的同时使用MTX的药理动力学.
主要成果:
- 同时使用MTX和RFP可增加33%的全身暴露.
- 同时使用MTX和FBX可增加17%的全身暴露.
- 结合RFP和FBX与MTX,风险增加了52%,与PBPK模型预测一致.
结论:
- PBPK模型准确地预测了MTX与RFP和FBX的临床DDI.
- 药物载体在与RFP和FBX等抑制剂联合使用时显著影响MTX暴露.
- 开发的PBPK模型是预测MTX传送器介导DDI的宝贵工具.
