Aldosterone release causes sodium and water retention, which causes increased blood volume, and a subsequent increase in blood pressure, which is sensed by the baroreceptors. [39] To maintain normal homeostasis these receptors also detect low blood pressure or low blood volume, causing aldosterone to be released.
It selectively stimulates secretion of aldosterone. The secretion of aldosterone has a diurnal rhythm. Control of aldosterone release from the adrenal cortex: [citation needed] The role of the renin–angiotensin system: Angiotensin is involved in regulating aldosterone and is the core regulator. Angiotensin II acts synergistically with potassium.
Stimulation by ATII of the adrenal cortex to release aldosterone, a hormone that acts on kidney tubules, causes sodium and chloride ions retention and potassium excretion. Sodium is a "water-holding" ion, so water is also retained, which leads to increased blood volume, hence an increase in blood pressure.
Most of the known actions of Ang II are mediated through the AT 1 receptors, for example vasoconstriction, aldosterone release, renal sodium reabsorption and vasopressin secretion. The AT 2 receptor also takes part in regulation of blood pressure and renal function but mediates antagonistic effects compared to the AT 1 receptor. [8] [10] [11] [12]
A mineralocorticoid receptor antagonist (MRA or MCRA) [1] or aldosterone antagonist, is a diuretic drug which antagonizes the action of aldosterone at mineralocorticoid receptors. This group of drugs is often used as adjunctive therapy, in combination with other drugs, for the management of chronic heart failure .

These drugs inhibit the first and rate-limiting step of the renin–angiotensin–aldosterone system (RAAS), namely the conversion of angiotensinogen to angiotensin I. This leads to a totality in absence of angiotensin II based on the rationale that renin only acts to inhibit this step unlike Angiotensin Converting Enzyme which is also involved ...
Antiglucocorticoid drugs are a treatment option for Cushing's syndrome, a condition characterized by excessive cortisol production. These medications are primarily used in two scenarios: as preoperative treatment to manage symptoms and reduce surgical risks, and as a long-term solution when surgery has failed or is not feasible.
