Eplerenone: a new selective aldosterone receptor antagonist.
Eplerenone is a specific aldosterone receptor antagonist that has been shown to have antihypertensive efficacy and to reduce end-organ manifestations in experimental animal models. Studies in humans have confirmed the blood pressure-lowering efficacy of this agent, as well as providing evidence of benefit in congestive heart failure. The side-effect profile indicates that the specificity of eplerenone for the mineralocorticoid receptor is responsible for the lower incidence of sex hormone- related side-effects than have been seen with other mineralocorticoid receptor blockers. Hyperkalemia is most frequently observed with eplerenone among patients with severe impairment of renal function and in diabetics with microalbuminuria, especially in combination with angiotensin-converting enzyme inhibitors. This agent appears to be a promising and effective new addition for the treatment of hypertension and heart failure with few of the side-effects that have plagued earlier drugs of this class.
