What type of drugs are diuretics primarily used for?

Diuretics are primarily used to increase urinary output, which is their main mechanism of action. By promoting the expulsion of sodium and water from the body through urine, they help reduce fluid retention. This action is particularly useful in treating conditions like hypertension, heart failure, and edema, where excess fluid can lead to complications.

The therapeutic effects of diuretics can indirectly affect other conditions, such as blood pressure, by decreasing overall fluid volume. However, their primary function remains focused on enhancing renal excretion. They are not utilized for pain relief or mood stabilization, as these issues require completely different classes of medications. Thus, the ability of diuretics to increase urine production is what defines their primary use in medical treatment.
