How It Works

Spironolactone belongs to a group of medications known as potassium-sparing diuretics, and it is also considered to be an aldosterone receptor antagonist. The medication works by blocking the action of aldosterone. It accomplishes this by binding to certain receptors in the kidneys that rely on aldosterone to regulate the body's balance of salt and water. When aldosterone is blocked, higher levels of sodium and other salts can be excreted through the kidneys and removed from the body through urination. As the salt exits the body, it takes water along with it, and excess fluid is also removed from the body. In this way, the medication lowers blood pressure and reduces fluid retention.
