Aldosterone is a hormone that causes the tubules of the kidneys to retain sodium and water. This increases the volume of fluid in the body, and drives blood pressure up. Many drugs, such as spironolactone, lower blood pressure by blocking the aldosterone receptor. Aldosterone is part of the renin-angiotensin system.
