摘要
Rifabutin induces CYP3A4 and may substantially lower axitinib concentrations, reducing efficacy. The effect is expected to be less than with rifampicin but is still clinically relevant.
用白話說明這項交互作用的意義
Axitinib and Rifabutin can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Axitinib belongs to Oncology; Rifabutin belongs to Anti Bacterial.
為什麼會發生
Rifabutin induces CYP3A4 and CYP1A1 pathways, increasing axitinib clearance.
處置方式
Avoid concomitant use where possible and select an agent with no enzyme-inducing potential. If it is unavoidable, monitor response and consider a gradual axitinib dose increase.
