NCIt related terms : Aldosterone inhibitor (mineralocorticoid receptor antagonist);
NCIt definition : A class of agents that act by selectively inhibiting aldosterone receptor activation
with diuretic activity. Aldosterone receptor antagonists bind to and block the activation
of aldosterone (mineralocorticoid) receptors on the epithelial cells in the late distal
tubule and collecting duct of the kidney, thus preventing the synthesis of aldosterone-induced
proteins which enhance Na retention and K and H secretion. The enhanced excretion
of Na produces diuresis ultimately resulting in a reduction in blood pressure without
the loss of K .;
Alternative definition : ACC/AHA: Spironolactone or eplerenone, which antagonize the action of aldosterone
at mineralocorticoid receptors;
