摘要
Dronedarone markedly prolongs the QT interval and is contraindicated with other QT-prolonging drugs that can induce torsades de pointes. Adding levofloxacin increases the risk of life-threatening arrhythmia.
用白話說明這項交互作用的意義
Dronedarone and Levofloxacin 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; Levofloxacin belongs to Anti Bacterial.
為什麼會發生
Additive blockade of cardiac potassium channels prolonging ventricular repolarization.
處置方式
Do not co-administer; select an antibiotic without QT liability. If a fluoroquinolone is essential, dronedarone must be withheld first.
