Indapamide is prescribed for the treatment of high blood pressure (hypertension). Although it belongs to a group of medicines called diuretics (which generally work by making the kidneys pass more urine out of the body), at the doses prescribed for hypertension, indapamide is considered to work by widening (dilating) blood vessels. By widening the blood vessels, it reduces the pressure inside the blood vessels and over time this leads to a lowering of high blood pressure.
