Edema and principles of diuretic use.

Abstract

Diuretics have changed the approach to many disease and have turned once fatal conditions into tolerable ones. Treatment of salt and water overload and edema can be quite satisfying for the clinician as long as the patient is closely watched for side effects. Thiazide diuretics have their greatest use in hypertension, loop diuretics in edema and congestive heart failure, CA inhibitors in glaucoma and altitude sickness, potassium-sparing diuretics in hypokalemia induced by other diuretics and ascites, and osmotic diuretics in acute renal failure and dialysis. They are among the most widely prescribed medications in the world today and rightly have a prominent place in the armamentarium against disease.
