摘要
Selumetinib is metabolized mainly by CYP3A4, and aprepitant can increase its exposure. This may heighten toxicities such as GI effects, rash and cardiomyopathy.
用白話說明這項交互作用的意義
Aprepitant and Selumetinib 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.
Aprepitant belongs to Gastrointestinal Tract; Selumetinib belongs to Oncology.
為什麼會發生
Aprepitant inhibits CYP3A4, reducing selumetinib clearance.
處置方式
Avoid if possible; otherwise reduce the selumetinib dose per labeling and monitor for adverse effects. Resume the prior dose after the inhibitor is stopped for about three half-lives.
