<p>Eplerenone selectively binds to the mineralocorticoid receptor and blocks the binding of aldosterone, a key component in the renin-angiotensin-aldosterone-system, which is involved in the regulation of BP and pathophysiology of CV disease. Aldosterone binds to mineralocorticoid receptors in both epithelial (e.g. kidney, GI tract) and nonepithelial (e.g. heart, blood vessels, brain) tissues; causing increases in BP by inducing Na reabsorption, vascular remodelling, water retention, endothelial dysfunction and possibly other mechanisms.</p>
