Résumé

Ibutilide is a potent QT-prolonging class III antiarrhythmic with a high torsades risk. Gemifloxacin adds to the effect and may increase the chance of life-threatening arrhythmia.

Ce que signifie cette interaction, en termes simples

Gemifloxacin and Ibutilide 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.

Gemifloxacin belongs to Anti Bacterial; Ibutilide belongs to Cardiovascular.

Niveau de preuve: Moderate

Pourquoi elle survient

Conduite à tenir
