Aldosterone is a steroid hormone (mineralocorticoid family) produced by the outer section (zona glomerulosa) of the adrenal cortex in the adrenal gland.[1][2] It plays a central role in the regulation of blood pressure mainly by acting on the distal tubules and collecting ducts of the nephron, increasing reabsorption of ions and water in the kidney, to cause the conservation of sodium, secretion of potassium, increased water retention, and increased blood pressure.[1] When dysregulated, aldosterone is pathogenic and contributes to the development and progression of cardiovascular and renal disease.[2] Aldosterone has exactly the opposite function of the atrial natriuretic hormone secreted by the heart.[1]

Drugs that interfere with the secretion or action of aldosterone are in use as antihypertensives, like lisinopril, which lowers blood pressure by blocking the angiotensin-converting enzyme (ACE), leading to lower aldosterone secretion; its net effect is to reduce sodium and water retention but increase retention of potassium. Aldosterone is part of the renin-angiotensin system. Another example is spironolactone, a potassium-sparing diuretic, which decreases blood pressure by releasing fluid from the body while retaining potassium.

It was first isolated by Simpson and Tait in 1953.[3]
