Mechanism & Pharmacology

Simplified explanation

Eplerenone operates primarily as an aldosterone receptor antagonist, which means it specifically blocks the effects of aldosterone on target organs. This hormone is produced by the adrenal glands and plays a key role in regulating blood pressure and fluid balance. By inhibiting aldosterone, eplerenone promotes the excretion of sodium and water while retaining potassium, leading to decreased blood volume and lower blood pressure.

Moreover, eplerenone helps in alleviating cardiac stress by reducing fluid overload in heart failure patients. Its selective nature means it tends to have fewer hormonal side effects compared to other drugs in its class, making it a more desirable option for long-term management of conditions like hypertension and chronic heart failure.

Clinical terms

Understanding eplerenone also involves some essential pharmacological terms. The drug is classified under the ATC code C03DA04, targeting the cardiovascular system as a potassium-sparing diuretic.

Key terms include:

• Aldosterone antagonist: A drug that blocks the actions of aldosterone.
• Diuresis: The increased production of urine.
• Hyperkalemia: Elevated potassium levels in the blood, which can result from eplerenone use.
• Left Ventricular Ejection Fraction (LVEF): A percentage that reflects how well the heart pumps with each beat.
• Renal impairment: Reduced kidney function, which is crucial to monitor while on eplerenone.

Indications & Off-Label Uses
