Eplerenone
Identification
- Summary
Eplerenone is an aldosterone receptor antagonist used to improve survival of patients with symptomatic heart failure and to reduce blood pressure.
- Brand Names
- Inspra
- Generic Name
- Eplerenone
- DrugBank Accession Number
- DB00700
- Background
Eplerenone, an aldosterone receptor antagonist similar to spironolactone, has been shown to produce sustained increases in plasma renin and serum aldosterone, consistent with inhibition of the negative regulatory feedback of aldosterone on renin secretion. The resulting increased plasma renin activity and aldosterone circulating levels do not overcome the effects of eplerenone. Eplerenone selectively binds to recombinant human mineralocorticoid receptors relative to its binding to recombinant human glucocorticoid, progesterone and androgen receptors.

Eplerenone, an aldosterone receptor antagonist similar to spironolactone, has been shown to produce sustained increases in plasma renin and serum aldosterone, consistent with inhibition of the negative regulatory feedback of aldosterone on renin secretion. The resulting increased plasma renin activity and aldosterone circulating levels do not overcome the effects of eplerenone. Eplerenone selectively binds to recombinant human mineralocorticoid receptors relative to its binding to recombinant human glucocorticoid, progesterone and androgen receptors.
- Mechanism of action
Eplerenone binds to the mineralocorticoid receptor and thereby blocks the binding of aldosterone (component of the renin-angiotensin-aldosterone-system, or RAAS). Aldosterone synthesis, which occurs primarily in the adrenal gland, is modulated by multiple factors, including angiotensin II and non-RAAS mediators such as adrenocorticotropic hormone (ACTH) and potassium. Aldosterone binds to mineralocorticoid receptors in both epithelial (e.g., kidney) and nonepithelial (e.g., heart, blood vessels, and brain) tissues and increases blood pressure through induction of sodium reabsorption and possibly other mechanisms.

Drug Interaction Integrate drug-drug
interactions in your softwareAbacavir Eplerenone may increase the excretion rate of Abacavir which could result in a lower serum level and potentially a reduction in efficacy. Abametapir The serum concentration of Eplerenone can be increased when it is combined with Abametapir. Abatacept The metabolism of Eplerenone can be increased when combined with Abatacept. Abiraterone The metabolism of Eplerenone can be decreased when combined with Abiraterone. Acalabrutinib The metabolism of Eplerenone can be decreased when combined with Acalabrutinib. Acebutolol Eplerenone may increase the hypotensive activities of Acebutolol. Aceclofenac The risk or severity of renal failure, hyperkalemia, and hypertension can be increased when Aceclofenac is combined with Eplerenone. Acemetacin The therapeutic efficacy of Eplerenone can be decreased when used in combination with Acemetacin. Acetaminophen Eplerenone may increase the excretion rate of Acetaminophen which could result in a lower serum level and potentially a reduction in efficacy. Acetyldigitoxin Eplerenone may decrease the excretion rate of Acetyldigitoxin which could result in a higher serum level.
