概要

Ketoconazole increases disopyramide levels and both drugs prolong the QT interval. This raises the risk of torsades de pointes and other ventricular arrhythmias.

この相互作用をわかりやすく説明すると

Disopyramide and Ketoconazole 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.

Disopyramide belongs to Cardiovascular; Ketoconazole belongs to Anti Fungals.

エビデンスレベル: Moderate

なぜ起こるのか

CYP3A4 inhibition by ketoconazole raises disopyramide exposure, combined with additive QT prolongation.

対処法

Avoid the combination. Use an antifungal with less QT and CYP3A4 effect, or an alternative antiarrhythmic.
