It is designed to selectively target and block the mineralocorticoid receptor to reduce inflammation and fibrosis associated with kidney damage, thereby slowing disease progression.

Uses

Firendia Tablet 10 mg is primarily used for:

Chronic kidney disease (CKD) in patients with type 2 diabetes (T2D)
Diabetic nephropathy to reduce the risk of kidney function decline and cardiovascular events

Mechanism of Action

Firendia Tablet 10 mg works by selectively blocking mineralocorticoid receptors in the kidneys, heart, and blood vessels. This action reduces the effects of aldosterone, a hormone that contributes to inflammation, fibrosis, and fluid retention. By inhibiting these effects, Firendia Tablet 10 mg helps to reduce kidney damage and improve renal and cardiovascular outcomes.

How Long Does It Take to Work?

Firendia Tablet 10 mg typically begins to show clinical effects within a few weeks of starting treatment. However, significant improvements in kidney function and reduction in proteinuria may take several months to become fully apparent. Regular monitoring is necessary to assess the drug's effectiveness and adjust treatment as needed.

Absorption

Firendia Tablet 10 mg is well-absorbed after oral administration. Peak plasma concentrations are usually reached within 1 to 2 hours. The drug is absorbed effectively and reaches therapeutic levels necessary for its intended effects on kidney and cardiovascular health.

Route of Elimination

Firendia Tablet 10 mg is metabolized primarily in the liver. It is then excreted through the feces and urine, with the majority of the drug being eliminated in the feces. The drug undergoes extensive hepatic metabolism and is not significantly excreted unchanged in the urine.

Dosage

The recommended starting dosage: 10 mg or 20 mg orally once daily based on estimated glomerular filtration rate (eGFR) and serum potassium thresholds. Increase dosage after 4 weeks to the target dose of 20 mg once daily, based on eGFR and serum potassium thresholds. Tablets may be taken with or without food.

Recommended Dosage-

eGFR ≥60 mL/min/1.73 m²: starting dose 20 mg once daily
eGFR ≥25 to <60 mL/min/1.73 m²: starting dose 10 mg once daily
eGFR <25 mL/min/1.73 m²: not recommended

For patients who are unable to swallow whole tablets, Finerenone may be crushed and mixed with water or soft foods.

Monitoring and Dose Adjustment: The target daily dose of Finerenone is 20 mg. Measure serum potassium 4 weeks after initiating treatment and adjust dose (see Table 2); if serum potassium levels are > 4.8 to 5.0 mEq/L, initiation of Finerenone treatment may be considered with additional serum potassium monitoring within the first 4 weeks based on clinical judgment and serum potassium levels. Monitor serum potassium 4 weeks after a dose adjustment and throughout treatment and adjust the dose as needed.

Missed doses: Direct a patient to take a missed dose as soon as possible after it is noticed, but only on the same day. If this is not possible, the patient should skip the dose and continue with the next dose as prescribed.

The typical dosage of Firendia Tablet 10 mg is:

Initial Dose: 10 mg once daily.
Maintenance Dose: The dose can be adjusted based on individual response and tolerability, with a usual range of 10 mg to 20 mg once daily.

Dosage adjustments may be necessary for patients with renal impairment or those taking other medications that interact with Firendia Tablet 10 mg.
