Résumé

Hydrochlorothiazide can raise dofetilide concentrations and may cause hypokalemia or hypomagnesemia, both of which promote QT prolongation. This increases the risk of torsades de pointes and ventricular arrhythmias.

Ce que signifie cette interaction, en termes simples

Captopril-hydrochlorothiazide and Dofetilide 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.

Captopril-hydrochlorothiazide belongs to Cardiovascular; Dofetilide belongs to Cardiovascular.

Niveau de preuve: High

Pourquoi elle survient

Thiazides reduce renal clearance of dofetilide (inhibiting cationic renal secretion) and cause electrolyte depletion, adding to QT prolongation.

Conduite à tenir

Avoid per dofetilide labeling; use an alternative antihypertensive or antiarrhythmic and correct potassium and magnesium if dofetilide is essential.
