An antimineralocorticoid, also known as a mineralocorticoid receptor antagonist (mcra) or aldosterone antagonist, is a diuretic drug which antagonizes the action of aldosterone at mineralocorticoid receptors.

Aldosterone Antagonists Overview
Aldosterone antagonists (antimineralocorticoid or mineralocorticoid receptor antagonists) are diuretics or water pills used for the treatment of high blood pressure or heart failure.they work by inhibiting the effects of aldosterone, a mineralocorticoid hormone secreted by the adrenal gland.aldosterone release causes retention of sodium and water, which causes.
Aldosterone is the main mineralocorticoid hormone in the body and is produced in the adrenal cortex of the adrenal gland.
Two common aldosterone receptor antagonists are spironolactone: Considering they are useful for such common and critical illnesses as resistant hypertension (high blood pressure), congestive heart failure, and cirrhosis, it is surprising that they are relatively unknown. The addition of aldosterone antagonists to the conventional therapy of myocardial failure and of selected cases of hypertension thus appears beneficial, resulting in an improved survival rate and a reduced incidence of cardiac complications. Aldosterone receptor antagonists (also called an antimineralocorticoid, mcra, and sometimes mra) are a class of drugs which block the effects of aldosterone.
Five decades ago, cella tried to combine the elements of progesterone and digoxin for the antimineralocorticoid and cardiotonic effect, respectively, thereby developing a nonselective aldosterone receptor antagonist called spironolactone.
Eplerenone binds to the mineralocorticoid receptor and blocks the binding of aldosterone, thereby decreasing sodium resorption and subsequently increasing water outflow. The two commonly used aldosterone receptor antagonists are spironolactone and eplerenone. Eplerenone is used in the treatment of hypertension and congestive heart failure. Aldosterone antagonists (also called aldosterone receptor antagonists) are an underappreciated and underutilized class of medications.
Aldosterone was first isolated by.
Major clinical trials involving spironolactone (rales) and eplerenone (ephesus) aras have shown significant benefits in the treatment of congestive heart failure (chf). Aldosterone is a downstream effector of angiotensin ii in the. This review article, after a brief recall of the physiology of the aldosterone system, addresses the emerging role of aldosterone in. This list doesn’t include every brand name.
Canadian brand names are in brackets.
Eplerenone (inspra) spirinolactone (aldactone) be aware: This article is an overview of the relevant past and recent findings regarding the interaction between aldosterone, the mr, and mineralocorticoid receptor antagonists (mras) in a variety of clinical conditions, including primary aldosteronism (pa), primary hypertension, resistant hypertension (rhtn), obstructive sleep apnea (osa), heart failure (hf), and chronic. Aldosterone increases sodium reabsorption by the kidneys, salivary glands, sweat glands and. This group of drugs is often used as adjunctive therapy, in combination with other drugs, for the management of chronic heart failure.
An aldosterone receptor antagonist that binds to the mineralocorticoid receptors in the kidney, heart, blood vessels and brain, blocking the binding of.
Generic names are listed first. 1,2 this review presents an overview of the physiology and clinical studies involved with both steroidal (spironolactone and eplerenone) mineralocorticoid receptor antagonists (mra). A selective aldosterone receptor antagonist. Aldosterone antagonists are diuretics or “water pills.” they may also be called aldosterone receptor blockers.
This leads to a decrease in blood pressure.
