What is the difference between eplerenone and spironolactone?

Eplerenone (Inspra) and spironolactone (Aldactone) are both aldosterone blockers. However, eplerenone is a selective mineralocorticoid receptor antagonist, so it does not have anti-androgenic side effects like spironolactone. In other words, eplerenone is less likely to cause side effects such as gynecomastia, impotence, and low sex drive in men and menstrual changes in women.

Is eplerenone safe for the kidneys?

Eplerenone is contraindicated in people with severely impaired kidney function (creatinine clearance 30 mL/minute or lower). The risk of hyperkalemia (high potassium level) is higher in patients with reduced kidney function.
