Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Finerenone is a nonsteroidal, selective antagonist of the mineralocorticoid receptor (MR). It binds to the MR and inhibits the recruitment of coactivators, thereby reducing the expression of pro-inflammatory and pro-fibrotic mediators in the kidney and heart.
Percorten (desoxycorticosterone pivalate) is a synthetic mineralocorticoid that binds to and activates the mineralocorticoid receptor (MR) in the renal distal tubule, leading to increased sodium reabsorption, increased potassium and hydrogen ion excretion, and water retention, thereby expanding extracellular fluid volume and increasing blood pressure.
To reduce the risk of sustained e GFR decline, end-stage kidney disease, cardiovascular death, non-fatal myocardial infarction, and hospitalization for heart failure in adult patients with chronic kidney disease (CKD) associated with type 2 diabetes.
Adjunctive therapy in adrenocortical insufficiency (Addison's disease) for mineralocorticoid replacement,Off-label: Treatment of orthostatic hypotension due to autonomic dysfunction
10 mg orally once daily initially, then titrate to 20 mg once daily after 4 weeks if tolerated.
1-5 mg intramuscularly or subcutaneously daily with dose adjusted based on clinical response and electrolyte monitoring.
The terminal elimination half-life is approximately 2–4 hours in healthy subjects. In patients with renal impairment, the half-life may be prolonged up to 6–8 hours, allowing for once-daily dosing in chronic kidney disease.
Terminal elimination half-life is approximately 30-40 minutes. Clinically, the short half-life necessitates frequent dosing (e.g., every 6-12 hours) to maintain therapeutic effect in mineralocorticoid replacement.
Primarily metabolized by CYP3A4 (≈90%) and to a lesser extent by CYP2C8 (≈10%). No active metabolites.
Primarily hepatic via reduction and conjugation; excreted in urine as metabolites. Desoxycorticosterone pivalate is a prodrug that is hydrolyzed to desoxycorticosterone, which is then metabolized.
Approximately 80% of the dose is eliminated via feces (primarily as unchanged drug) and ~20% via urine (mostly as metabolites). Renal excretion of unchanged drug is minimal (less than 1%).
Renal (biliary/fecal negligible). Approximately 50-70% of a dose is excreted as metabolites in urine; <5% unchanged.
Approximately 92% bound to plasma proteins, primarily albumin and alpha-1 acid glycoprotein.
Approximately 90-94% bound to albumin and corticosteroid-binding globulin (CBG).
The apparent volume of distribution is approximately 50 L (about 0.7 L/kg in a 70 kg adult), indicating moderate tissue distribution, likely into kidney and heart tissues.
Vd approximately 0.5-0.8 L/kg. Clinical meaning: Distributes primarily into extracellular fluid; low Vd indicates limited tissue penetration.
Oral bioavailability is about 90–95% in healthy subjects, indicating nearly complete absorption after oral administration. Food does not significantly affect absorption.
Oral: Approximately 50-70% (high first-pass metabolism). IM/SC: 100% (assumed).
e GFR 25-59 m L/min/1.73 m²: Initiate 10 mg once daily; continue 10 mg if tolerated. e GFR <25 m L/min: Not recommended.
No specific GFR-based dose adjustments established; use with caution in renal impairment due to potential for fluid retention and hypertension.
Child-Pugh B (moderate impairment): 10 mg once daily. Child-Pugh C (severe impairment): Not recommended.
No specific Child-Pugh based dose adjustments; caution in severe hepatic impairment due to reduced metabolism and increased risk of adverse effects.
Safety and efficacy not established in pediatric patients.
0.1-0.3 mg/kg intramuscularly or subcutaneously daily, divided every 12-24 hours, with titration based on clinical response.
No specific dose adjustment required; monitor renal function closely.
Initiate at lower end of adult dose (1 mg daily) with careful monitoring for fluid overload and electrolyte disturbances due to age-related renal and cardiovascular changes.
No FDA boxed warning.
None
Hyperkalemia: Monitor serum potassium levels; may require dose adjustment or discontinuation.,Hypotension: Risk increased in patients with volume depletion or concomitant antihypertensive therapy.,Acute kidney injury: Monitor renal function; consider temporary discontinuation in setting of significant renal impairment.,Hepatic impairment: Not recommended in patients with severe hepatic impairment (Child-Pugh C).
May cause severe hypertension, edema, congestive heart failure, hypokalemia, or metabolic alkalosis. Monitor blood pressure, serum electrolytes, and body weight. Use with caution in patients with cardiac disease, renal impairment, or hepatic disease. Avoid excessive sodium intake.
Concomitant use with strong CYP3A4 inhibitors (e.g., itraconazole, clarithromycin, ketoconazole, ritonavir).,Addison's disease (adrenal insufficiency).,Serum potassium > 5.0 m Eq/L at initiation.
Hypersensitivity to desoxycorticosterone or any component,Severe hypertension,Hyperkalemia,Edema or fluid overload states,Congestive heart failure,Severe renal impairment
Avoid grapefruit and grapefruit juice as they inhibit CYP3A4 and may increase finerenone exposure. No other food interactions noted.
Avoid high-potassium foods (e.g., bananas, oranges, salt substitutes) as Percorten increases potassium retention. Limit sodium intake to manage fluid balance.
Based on animal studies, Kerendia (finerenone) is associated with fetal harm. In rats, embryofetal toxicity (reduced fetal weights, delayed ossification) and malformations (cardiovascular, skeletal) were observed at maternal exposures below the maximum recommended human dose. In rabbits, increased post-implantation loss and decreased fetal weights occurred. There are no adequate human studies. Use is contraindicated in pregnancy. Avoid in women of childbearing potential not using effective contraception.
Percorten (desoxycorticosterone pivalate) is a mineralocorticoid. Data in pregnant women are limited. In animal studies, corticosteroids have been shown to be teratogenic. Use during pregnancy only if clearly needed. First trimester: Possible increased risk of cleft palate and intrauterine growth restriction. Second and third trimesters: Potential for adrenal suppression in the fetus/newborn.
No data on presence in human milk, effects on breastfed infant, or milk production. Excreted in rat milk. M/P ratio unknown. Due to potential for serious adverse reactions (e.g., hyperkalemia, hypotension), breastfeeding is not recommended during therapy and for 1 week after last dose.
Corticosteroids are excreted in breast milk in small amounts. Desoxycorticosterone pivalate specific data are lacking. M/P ratio not determined. At high maternal doses, monitor infant for signs of adrenal suppression. Use with caution.
Kerendia is contraindicated in pregnancy. No dose adjustments are provided due to lack of human data; use is not recommended. Pharmacokinetic changes in pregnancy are unknown, but dose modifications are not applicable as therapy should be discontinued if pregnancy occurs.
Pregnancy may increase clearance of corticosteroids, potentially requiring dose adjustments. However, specific pharmacokinetic data for Percorten are lacking. Use lowest effective dose and monitor clinical response and serum levels if available.
Monitor serum potassium closely, especially in patients with e GFR <30 m L/min/1.73m² or baseline K+ >5.0 m Eq/L. Avoid use with strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, ritonavir). Contraindicated with concomitant mineralocorticoid receptor antagonists (e.g., spironolactone, eplerenone). Use caution with moderate CYP3A4 inhibitors (e.g., erythromycin, verapamil) and moderate CYP3A4 inducers (e.g., rifampin, phenytoin). Assess e GFR and serum potassium before initiation and at 1 month after starting or adjusting dose.
Percorten (desoxycorticosterone pivalate) is a mineralocorticoid used for adrenal insufficiency. Monitor for hypertension, hypokalemia, and edema. Titrate dose based on blood pressure and serum potassium. Use with caution in heart failure or renal impairment.
