    Mineralocorticoid Receptor Antagonism in Chronic Kidney Disease
    (Elsevier, 2021-06-10) Georgianos, Panagiotis I.; Agarwal, Rajiv; Medicine, School of Medicine
    The overactivation of the mineralocorticoid receptor (MR) in animal models of chronic kidney disease (CKD) increases sodium retention and hypertension and provokes inflammation and fibrosis in the kidneys, blood vessels, and the heart; these processes play an important role in the progression of cardiorenal disease. Accordingly, blockade of the MR is an attractive therapeutic intervention to retard the progression of CKD and improve cardiovascular morbidity and mortality. Finerenone is a novel, nonsteroidal MR antagonist (MRA) with a unique mode of action that is distinct from currently available steroidal MRAs. In animal models of CKD, finerenone has a more favorable benefit/risk ratio as compared with the steroidal MRAs such as spironolactone and eplerenone. In patients with type 2 diabetes and heart and/or kidney disease, phase II trials have revealed that compared with spironolactone, eplerenone, or placebo, finerenone displays benefits that exceed the risks of MR antagonism. In patients with CKD and type 2 diabetes, a large phase III trial has shown that, compared with placebo, finerenone improved kidney failure and cardiovascular outcomes. In the first part of this article, we explore the safety and efficacy of spironolactone and eplerenone in early- and late-stage CKD. In the second part, we describe the mechanism of action of finerenone and discuss the promising role of this nonsteroidal MRA as a novel therapeutic opportunity to improve clinical outcomes in patients with CKD.

    The Use of Aldosterone Receptor Blockers in the Treatment of Hypertension
    (Wiley, 2004-11) Weinberger, Myron H.; Medicine, School of Medicine
    The emerging role of aldosterone in hypertension and cardiovascular diseases has prompted a renewal of interest in therapeutic approaches designed to interfere with the action of this mineralocorticoid hormone. While spironolactone has long been used for this purpose, side effects, largely attributable to the interaction of this agent with non-mineralocorticoid steroid receptors, has reduced the enthusiasm for its use. Eplerenone, a specific aldosterone receptor blocker with a lower incidence of the sex hormone-related side effects than spironolactone, has been used in several recent clinical trials in hypertension and congestive heart failure. This review will highlight the major findings from these studies.
