Résumé

Both agents prolong the QT interval and dronedarone labeling contraindicates use with QT-prolonging drugs that may induce torsades de pointes. Together they markedly raise the risk of life-threatening arrhythmia.

Ce que signifie cette interaction, en termes simples

Dronedarone and Moxifloxacin 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; Moxifloxacin belongs to Anti Bacterial.

Niveau de preuve: High

Pourquoi elle survient
