Two medicines, side by side

Eplerenone vs furosemide

Eplerenone and furosemide are both labeled for high blood pressure and heart failure. Drugs@FDA records approvals of eplerenone since 2002 and of furosemide since 1966. Pharmacies paid $0.308 per eplerenone 25 mg tablet and $0.490 per mL (Furosemide 20 mg/2 mL vial) (NADAC, October 7, 2026); the strengths differ, so the two prices are not like for like. In FDA's classes, eplerenone is an aldosterone antagonist and furosemide a loop diuretic.

Check it at the source: the eplerenone FDA label on DailyMed (effective June 23, 2025); the furosemide FDA label on DailyMed (effective September 30, 2025).
