摘要
Dasatinib prolongs the QT interval and amitriptyline does as well, so the combination adds arrhythmic risk. Dasatinib is a weak CYP3A4 inhibitor, and any effect on amitriptyline levels is probably small.
用白話說明這項交互作用的意義
Amitriptyline and Dasatinib 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; Dasatinib belongs to Oncology.
為什麼會發生
Additive QT prolongation, with possible minor CYP3A4 inhibition by dasatinib.
處置方式
Avoid if possible; otherwise obtain a baseline ECG, correct hypokalaemia and hypomagnesaemia, and monitor the QTc periodically. Reduce the amitriptyline dose if anticholinergic or cardiac toxicity appears.
