Mineralocorticoid receptor antagonist

A mineralocorticoid receptor antagonist is a type of medication that blocks a hormone receptor in the body called the mineralocorticoid receptor, which normally helps regulate blood pressure and salt balance. By blocking this receptor, these drugs prevent the hormone aldosterone from causing the kidneys to retain excess sodium and water, which helps lower blood pressure and reduce strain on the heart. These medications are commonly used to treat conditions like high blood pressure and heart failure, and they work by essentially telling your body to hold onto less salt and fluid.
