概要
Amiodarone is a moderate CYP3A4 inhibitor and can raise entrectinib exposure, increasing its toxicities. Both drugs also prolong the QT interval, so the risk of torsades de pointes is additive.
この相互作用をわかりやすく説明すると
Amiodarone and Entrectinib 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.
Amiodarone belongs to Cardiovascular; Entrectinib belongs to Oncology.
なぜ起こるのか
CYP3A4 inhibition by amiodarone reduces entrectinib clearance, plus additive QT prolongation.
対処法
Prefer an alternative antiarrhythmic. If unavoidable, reduce the entrectinib dose per labeling for moderate CYP3A4 inhibitors and monitor ECG and electrolytes.
