title: Exciting new drugs on the horizon - eplerenone, a selective aldosterone receptor antagonist (SARA).
abstract: Despite major advances many cardiovascular disorders remain poorly controlled. As a result the search for newer agents goes on. Anti-neurohormonal agents have been the most successful agents: beta-blockers, ACE inhibitors and angiotensin receptor blockers. To these we now add anti-aldosterone strategies with the phenomenal success of spironolactone in reducing mortality in severe heart failure. A more recent and more selective aldosterone receptor antagonist has been developed, eplerenone, and it shows considerable promise in managing and preventing the complications of hypertension. It may have a role both being anti-fibrotic and anti-neurohormonal in mild to moderate heart failure, in post-MI left ventricular dysfunction and in progressive renal disease. The EPHESUS trial which randomised patients with heart failure due to impaired left ventricular systolic function aims to randomise 6,200 patients to eplerenone or placebo on top of standard therapy and follow subjects until 1,012 deaths have occurred (approx. 2.5 years of follow up). This and other trials with the novel strategy of selective aldosterone antagonism are eagerly awaited. The beneficial effects established by the earliest anti-neurohormonal agents give us confidence that further benefits could be obtained by this intellectual strategy.
