This medicine contains the active ingredient spironolactone which belongs to a group of medicines called diuretics, also known as water tablets. These medicines cause the kidneys to produce more urine, and in that way they free your body from retaining the amounts of water higher than needed. Spironolactone is prescribed for the treatment of ascites and edema (water retention caused by heart failure, liver disease (cirrhosis) or malignant disease), hypertension (high blood pressure), diagnosis and treatment of a primary aldosteronism (excessive production of aldosterone, a steroid produced by the adrenal gland).
