摘要
Erythromycin inhibits CYP3A4, raising dronedarone exposure, and itself prolongs the QTc interval. Dronedarone can in turn raise erythromycin levels, so torsades de pointes risk rises substantially.
用白話說明這項交互作用的意義
Dronedarone and Erythromycin are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.
Dronedarone belongs to Cardiovascular; Erythromycin belongs to Anti Bacterial.
為什麼會發生
CYP3A4 inhibition (raised dronedarone) plus additive QTc prolongation
處置方式
Do not co-administer; use a non-macrolide antibiotic and monitor the ECG if exposure has occurred.
