Potassium-sparing diuretics are diuretic drugs that do not promote the secretion of potassium into the urine.
They are used as adjunctive therapy, together with other drugs, in the treatment of hypertension and management of congestive heart failure. However, at low doses the use of potassium-sparing diuretics has not been found to produce a clinically significant reduction in blood pressure.
