Résumé

Clarithromycin markedly increases eplerenone exposure, raising the risk of hyperkalemia and associated arrhythmia. Eplerenone labeling contraindicates strong CYP3A4 inhibitors such as clarithromycin.

Ce que signifie cette interaction, en termes simples

Clarithromycin and Eplerenone 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.

Clarithromycin belongs to Anti Bacterial; Eplerenone belongs to Cardiovascular.

Niveau de preuve: High

Pourquoi elle survient

Clarithromycin is a strong CYP3A4 inhibitor and blocks the main metabolic pathway of eplerenone.

Conduite à tenir

Do not co-administer; use an antibiotic without strong CYP3A4 inhibition, such as azithromycin, or withhold eplerenone during the course. Check potassium if exposure has occurred.
