摘要
Rifabutin induces CYP3A4, though less potently than rifampicin, and may lower brexpiprazole concentrations. Reduced efficacy is possible.
用白話說明這項交互作用的意義
Brexpiprazole 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.
Brexpiprazole belongs to Central Nervous System; Rifabutin belongs to Anti Bacterial.
為什麼會發生
Rifabutin induces CYP3A4, increasing brexpiprazole clearance.
處置方式
Increase the brexpiprazole dose toward twice the usual dose over 1 to 2 weeks and monitor response. Reduce it again when rifabutin is stopped.
