Chlorthalidone is a diuretic medication used to treat high blood pressure and edema (swelling). It works by helping the kidneys remove excess salt and water from the body, reducing the amount of fluid in the bloodstream. Think of it as a pressure release valve for your circulatory system. It's a long-acting diuretic, meaning its effects last longer compared to some other diuretics. It is often prescribed because of its effectiveness and affordability.
