Triamterene is used to remove excess salts from the body, while retaining potassium. It is used to treat swelling due to fluid retention (oedema) in heart diseases (cardiac failure), liver diseases (cirrhosis of the liver) or kidney diseases (nephrotic syndrome), and in edema associated with corticosteroid treatment. They are used alone or in combination with other diuretic which cause potassium depletion.
