摘要
Dacomitinib is a strong CYP2D6 inhibitor and can substantially raise amitriptyline concentrations. This may increase anticholinergic effects, sedation, QT prolongation and arrhythmia risk.
用白話說明這項交互作用的意義
Amitriptyline and Dacomitinib 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.
Amitriptyline belongs to Central Nervous System; Dacomitinib belongs to Oncology.
為什麼會發生
Dacomitinib inhibits CYP2D6, reducing the metabolism of amitriptyline and its active metabolite.
處置方式
Avoid if possible or reduce the amitriptyline dose and monitor for toxicity. Check an ECG and consider tricyclic levels in higher-risk patients.
