Eplerenone

Eplerenone is a prescription mineralocorticoid receptor antagonist available as film-coated tablets in 25 mg and 50 mg strengths.

Overview

Eplerenone is a prescription mineralocorticoid receptor antagonist available as film-coated tablets in 25 mg and 50 mg strengths.

Uses

Indicated for improving survival in stable patients with symptomatic heart failure with reduced ejection fraction following acute myocardial infarction, and treating hypertension to reduce cardiovascular event risk.

Dosage

For heart failure post-MI: initiate 25 mg daily, titrate to 50 mg daily within 4 weeks as tolerated. For hypertension: 50 mg daily, increase to 50 mg twice daily if needed. Monitor serum potassium before starting and periodically thereafter.

Side Effects

Most common reactions include hyperkalemia and increased creatinine in heart failure patients. Gynecomastia and vaginal bleeding reported in hypertension studies. Postmarketing reports include angioneurotic edema and rash.

Interactions

CYP3A inhibitors increase exposure; do not exceed 25 mg daily with moderate inhibitors. ACE inhibitors and ARBs increase hyperkalemia risk. NSAIDs may reduce antihypertensive effect and cause severe hyperkalemia.

Warnings

Hyperkalemia risk is higher in patients with impaired renal function, proteinuria, diabetes and those taking ACE inhibitors, ARBs, or NSAIDs. Contraindicated when serum potassium greater than 5.5 mEq/L, creatinine clearance 30 mL/min or less, or with strong CYP3A inhibitors.

Pregnancy

Limited human data. Animal studies showed no teratogenic effects at exposures 31-32 times the human dose.

Storage

Store at 25 degrees C (77 degrees F) with excursions permitted between 15-30 degrees C.
