Résumé

Diltiazem increases ivabradine exposure and also lowers heart rate itself. The combination can cause marked bradycardia, conduction block and related symptoms such as dizziness or syncope.

Ce que signifie cette interaction, en termes simples

Diltiazem and Ivabradine 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.

Diltiazem belongs to Cardiovascular; Ivabradine belongs to Cardiovascular.

Niveau de preuve: High

Pourquoi elle survient

Moderate CYP3A4 inhibition raises ivabradine concentrations, with additive sinus node slowing from both drugs.

Conduite à tenir
