摘要
Itraconazole raises disopyramide concentrations and both drugs prolong the QT interval. This can cause torsades de pointes and other serious arrhythmias, as well as anticholinergic and hypoglycemic effects from high disopyramide levels.
用白話說明這項交互作用的意義
Disopyramide and Itraconazole 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; Itraconazole belongs to Anti Fungals.
為什麼會發生
CYP3A4 inhibition raises disopyramide levels, with additive QT prolongation.
處置方式
Avoid the combination. Use a non-interacting antiarrhythmic or an antifungal without CYP3A4 inhibition.
