Aldosterone is a hormone that is critical in regulating the body's balance of salt and water. Excessive levels may play important roles in hypertension and heart failure. Additional agents that block this hormone are being developed. The actions of aldosterone blockers are similar to potassium-sparing diuretics, and like these agents, it poses some risk for high potassium levels, which in some cases can be dangerous.
