Description:
Renopro is indicated to reduce the risk of sustained eGFR decline, end-stage kidney disease, cardiovascular death, nonfatal myocardial infarction, and hospitalization for heart failure in adult patients with chronic kidney disease (CKD) associated with type 2 diabetes (T2D).
Finerenone is a nonsteroidal, selective antagonist of the mineralocorticoid receptor (MR), which is activated by aldosterone and cortisol and regulates gene transcription. Finerenone blocks MR mediated sodium reabsorption and MR overactivation in both epithelial (e.g., kidney) and nonepithelial (e.g., heart, and blood vessels) tissues. MR overactivation is thought to contribute to fibrosis and inflammation. Finerenone has a high potency and selectivity for the MR and has no relevant affinity for androgen, progesterone, estrogen and glucocorticoid receptors. In patients treated with Finerenone, the mean systolic blood pressure decreased by 3 mmHg and the mean diastolic blood pressure decreased by 1-2 mmHg at month 1, remaining stable thereafter. At a dose 4 times the maximum approved recommended dose, Finerenone does not prolong the QT interval to any clinically relevant extent. Finerenone is completely absorbed after oral administration but undergoes metabolism resulting in absolute bioavailability of 44%. Finerenone Cmax was achieved between 0.5 and 1.25 hours after dosing.
Finerenone exposure increased proportionally over a dose range of 1.25 to 80 mg (0.06 to 4 times the maximum approved recommended dosage). Steady state of finerenone was achieved after 2 days of dosing. The estimated steady-state geometric mean Cmax, md was 160 μg/L and steady-state geometric mean AUCt,md was 686 μg.h/L following administration of finerenone 20 mg to patients.
Absorption: Finerenone is completely absorbed after oral administration but undergoes metabolism resulting in absolute bioavailability of 44%. Finerenone Cmax was achieved between 0.5 and 1.25 hours after dosing. Effect of Food There was no clinically significant effect on finerenone AUC following administration with high fat, high calorie food.
Distribution: The volume of distribution at steady-state (Vss) of finerenone is 52.6 L. Plasma protein binding of finerenone is 92%, primarily to serum albumin, in vitro.
Elimination: The terminal half-life of finerenone is about 2 to 3 hours, and the systemic blood clearance is about 25 L/h.
Metabolism: Finerenone is primarily metabolized by CYP3A4 (90%) and to a lesser extent by CYP2C8 (10%) to inactive metabolites. Excretion About 80% of the administered dose is excreted in urine
