Capoten, which contains the active ingredient captopril, is used to treat many conditions associated with high blood pressure and heart disease. One of its most prominent uses is to lower high blood pressure, which helps reduce the risk of heart attacks or strokes.
Capoten is also used to improve heart function after a heart attack and to manage some cases of chronic heart failure. In addition, it is sometimes prescribed to treat diabetic kidney disease, as it helps protect the kidneys from damage.
