Finerenone: Uses, Interactions, and Mechanism of Action

Chronic kidney disease (CKD), particularly in individuals with type 2 diabetes (T2D), is a major public health concern. It significantly increases the risk of cardiovascular complications, kidney failure, and early mortality. Finerenone, a novel non-steroidal mineralocorticoid receptor antagonist (MRA), has gained recognition for its dual renal and cardiovascular protective effects. This article explores Finerenone’s clinical uses, mechanism of action, and key drug interactions to be aware of.

What is Finerenone?

Finerenone is a non-steroidal, selective mineralocorticoid receptor antagonist used to treat chronic kidney disease (CKD) associated with type 2 diabetes. It works by targeting and blocking mineralocorticoid receptors (MRs), which, when overactivated, contribute to inflammation, fibrosis, and progression of kidney and heart disease.

What distinguishes Finerenone from older MRAs like spironolactone or eplerenone is its higher selectivity and reduced hormonal side effects, making it a safer long-term option for patients with CKD and T2D.

Uses of Finerenone

1. Chronic Kidney Disease in Type 2 Diabetes

The primary indication for Finerenone is slowing the progression of CKD in patients with type 2 diabetes. These patients often experience albuminuria (excess protein in urine), declining kidney function, and increased risk of cardiovascular events.

Finerenone has been shown to:

  • Reduce albuminuria

  • Slow decline in estimated glomerular filtration rate (eGFR)

  • Lower risk of kidney failure

  • Reduce the likelihood of cardiovascular events such as heart attack, stroke, and hospitalization for heart failure

It is generally used in addition to standard therapy, including angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs), which are standard treatments for CKD and hypertension.

2. Cardiovascular Risk Reduction

Beyond kidney protection, Finerenone helps reduce cardiovascular complications in high-risk individuals. By blocking the harmful effects of aldosterone on the heart and blood vessels, Finerenone can reduce inflammation and fibrosis in the cardiovascular system.

Clinical data suggest benefits in:

  • Reducing left ventricular hypertrophy

  • Preventing heart failure hospitalizations

  • Lowering the risk of cardiovascular mortality in patients with CKD and diabetes

Mechanism of Action

Finerenone exerts its effect by selectively antagonizing mineralocorticoid receptors (MRs) in tissues like the kidneys, heart, and vasculature. These receptors are normally activated by aldosterone, a hormone involved in electrolyte balance and blood pressure regulation.

Pathological Role of MR Activation

In CKD and cardiovascular disease, MR activation leads to:

  • Sodium and water retention

  • Potassium excretion

  • Vascular inflammation

  • Cardiac and renal fibrosis

  • Oxidative stress

Finerenone blocks this pathway, reducing:

  • Fibrotic changes in the heart and kidneys

  • Inflammatory cytokine production

  • Proteinuria and kidney damage

  • Cardiac remodeling

Importantly, Finerenone does this without significant hormonal side effects, which are common with steroidal MRAs like spironolactone.

Drug Interactions

Due to its metabolic pathway and pharmacodynamic effects, Finerenone can interact with a variety of medications. Understanding these interactions is critical for safe and effective use.

1. CYP3A4 Inhibitors and Inducers

Finerenone is metabolized mainly via the CYP3A4 enzyme in the liver.

  • Strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, clarithromycin, ritonavir) can increase Finerenone levels, potentially leading to hyperkalemia and hypotension.

  • Strong CYP3A4 inducers (e.g., rifampin, carbamazepine, phenytoin, St. John’s Wort) can decrease Finerenone levels, reducing its efficacy.

2. Potassium-Elevating Agents

Since Finerenone can raise serum potassium, combining it with other potassium-sparing agents or potassium supplements increases the risk of hyperkalemia:

  • Potassium-sparing diuretics (e.g., amiloride, triamterene)

  • ACE inhibitors or ARBs (especially if potassium is already elevated)

  • Potassium supplements

3. NSAIDs

Nonsteroidal anti-inflammatory drugs (NSAIDs) may reduce kidney function and potentially increase the risk of acute kidney injury when used with Finerenone, particularly in dehydrated or elderly patients.

Adverse Effects and Monitoring

While Finerenone is generally well tolerated, certain risks need to be monitored:

Common Side Effects

  • Hyperkalemia (most common)

  • Hypotension

  • Dizziness

Monitoring Parameters

  • Serum potassium: Check before initiation, and regularly during treatment

  • eGFR: Assess kidney function before and during therapy

  • Blood pressure: Monitor for hypotension

Finerenone should not be initiated in patients with:

  • Serum potassium >5.0 mmol/L

  • eGFR <25 mL/min/1.73 m²

  • Severe hepatic impairment

Dose adjustments or discontinuation may be required based on lab values and tolerability.

Conclusion

Finerenone represents a significant advancement in the management of chronic kidney disease in people with type 2 diabetes. Its selective inhibition of mineralocorticoid receptors allows for effective reduction of both renal and cardiovascular risks without the hormonal side effects associated with older MRAs.

However, its use requires careful consideration of drug interactions and close monitoring of serum potassium and kidney function. With proper management, Finerenone can play a crucial role in slowing disease progression and improving long-term outcomes in a high-risk patient population.
