Summary
Voriconazole strongly inhibits CYP3A4 and can markedly raise eplerenone exposure, increasing the risk of hyperkalemia. Eplerenone labeling contraindicates strong CYP3A4 inhibitors.
What this interaction means in plain words
Eplerenone and Voriconazole 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.
Eplerenone belongs to Cardiovascular; Voriconazole belongs to Anti Fungals.
Why it happens
Inhibition of CYP3A4-mediated eplerenone metabolism by voriconazole.
What to do
Do not combine. Use an alternative mineralocorticoid antagonist or antifungal and check potassium.
