Potassium-sparing diuretics or antikaliuretics [1] refer to drugs that cause diuresis without causing potassium loss in the urine. [2] They are typically used as an adjunct in management of hypertension, cirrhosis, and congestive heart failure. [3] The steroidal aldosterone antagonists can also be used for treatment of primary hyperaldosteronism.

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.
ATC code C03 Diuretics is a therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System, a system of alphanumeric codes developed by the World Health Organization (WHO) for the classification of drugs and other medical products. [1] [2] [3] Subgroup C03 is part of the anatomical group C Cardiovascular system. [4]
The name mineralocorticoid derives from early observations that these hormones were involved in the retention of sodium, a mineral.The primary endogenous mineralocorticoid is aldosterone, although a number of other endogenous hormones (including progesterone [1] and deoxycorticosterone) have mineralocorticoid function.
Eplerenone, sold under the brand name Inspra, is an aldosterone antagonist type of potassium-sparing diuretic that is used to treat chronic heart failure and high blood pressure, particularly for people with resistant hypertension due to elevated aldosterone.
Hyporeninemic hypoaldosteronism is amenable to fludrocortisone treatment, [4] but the accompanying hypertension and edema can prove a problem in these patients, so often a diuretic (such as the thiazide diuretic, bendrofluazide, or a loop diuretic, such as furosemide) is used to control the hyperkalemia.
