1. What is Espironolactona Orion and what is it used for

The active substance of this medicine, spironolactone, reduces excess fluid in the body by increasing urinary secretion. It differs from many other diuretics in that potassium is not lost in the urine.

This medicine is used to treat:

• high blood pressure or heart failure, as additional treatment in patients who do not respond adequately to other treatments
• inflammations related to kidney, liver, or other diseases, when other treatments have not been effective
• primary aldosteronism (overactivity of the aldosterone hormone secretion in the adrenal glands).

It is possible that a doctor has prescribed this medicine for the treatment of a disease other than the one mentioned in this leaflet.
