How is finerenone different from spironolactone?

Spironolactone is an older mineralocorticoid antagonist with high rates of hyperkalemia and hormone side effects (breast tenderness, menstrual changes) in CKD. Finerenone is more selective — it provides the kidney protection with a lower potassium risk and fewer side effects, which is why it's licensed for diabetic kidney disease.

Can finerenone be used with SGLT2 inhibitors?

Yes — trials enrolled patients on both. Combination therapy (ACEi/ARB + SGLT2i + finerenone) is now recommended for diabetic kidney disease with albuminuria; each adds independent protection, and potassium monitoring is standard.

Nonsteroidal mineralocorticoid receptor antagonist

Finerenone (Kerendia) and Kidneys

Brand names: Kerendia • Drug class: Nonsteroidal mineralocorticoid receptor antagonist

Finerenone is a new-generation mineralocorticoid receptor antagonist for diabetic kidney disease. The FIDELIO-DKD trial (NEJM 2020) showed it cuts kidney failure risk by 18% on top of ACEi/ARB — without the potassium and hormone side effects of older spironolactone.

How it affects the kidneys

In diabetic CKD, finerenone blocks aldosterone-driven inflammation and fibrosis in the kidney — reducing albuminuria by ~30% and slowing progression. It is the third pillar of diabetic kidney protection, after ACEi/ARB and SGLT2 inhibitors.

Renal dosing guidance

10 mg or 20 mg once daily based on eGFR (20 mg if eGFR ≥60; 10 mg if 25-59). Start only if serum potassium ≤4.8 mEq/L. Monitor potassium at 1 month and then regularly. Use with caution below eGFR 25.
