Diuretic


A drug that increases the production of urine; it is commonly used in the treatment of oedema (too much water in body tissues), high blood pressure, and congestive heart failure.

There are several types of diuretics: including thiazides (e.g., hydrochlorothiazide), loop diuretics (frusemide), and others, amiloride and spironolactone. They work in different ways and can produce side effects chiefly electrolyte (especially sodium and potassium) imbalances.
