Rifamycins are widely used for treating mycobacterial and staphylococcal infections. Drug-drug interactions (DDI) caused by rifampicin (RIF) are a major issue. We used a model-based approach to predict the magnitude of DDI with RIF and rifabutin (RBT) for 217 cytochrome P450 (CYP) substrates. On average, DDI caused by low-dose RIF were twice as potent as those caused by RBT. Contrary to RIF, RBT appears unlikely to cause severe DDI, even with sensitive CYP substrates.
利福霉素广泛用于治疗分枝杆菌和葡萄球菌感染。利福平(RIF)引起的药物-药物相互作用(DDI)是一个主要问题。我们使用基于模型的方法来预测利福平(RIF)和利福布丁(RBT)对 217 种细胞色素 P450(CYP)底物的相互作用的程度。平均而言,低剂量 RIF 引起的 DDI 比 RBT 引起的 DDI 强两倍。与 RIF 相反,即使对于敏感的 CYP 底物,RBT 似乎也不太可能引起严重的 DDI。
