Which diuretic is typically used for management of hypertension?

Thiazide diuretics are commonly used in the management of hypertension due to their effectiveness in lowering blood pressure. These medications work primarily by inhibiting sodium reabsorption in the distal convoluted tubule of the nephron. This action leads to increased excretion of sodium and water, resulting in reduced blood volume, which in turn lowers blood pressure. Thiazide diuretics also have a favorable effect on endothelial function and may provide additional cardiovascular benefits.

In contrast, while potassium-sparing diuretics can help manage hypertension, they are often used in conjunction with other diuretics to prevent potassium loss rather than as first-line agents for hypertension management. Osmotic diuretics are typically utilized for managing specific conditions such as increased intracranial pressure or glaucoma rather than hypertension. Loop diuretics can also lower blood pressure but are mainly indicated for the treatment of conditions like heart failure or edema due to their potent diuretic action. Therefore, thiazide diuretics are the first-line choice for managing hypertension.
