Which of the following is a diuretic used for hypertension?

Diuretics lower blood pressure by increasing urine output, which reduces circulating blood volume and lowers arterial pressure. Among the options, the one that fits as a diuretic is furosemide. It’s a loop diuretic that blocks the Na-K-2Cl cotransporter in the thick ascending limb of the loop of Henle, leading to higher excretion of sodium, chloride, and water. This diuretic effect drops blood volume and helps lower blood pressure. Loop diuretics like furosemide are especially useful when edema is present or when a stronger diuretic effect is needed; for essential hypertension, thiazide diuretics are often preferred first, but furosemide is indeed a diuretic used in hypertensive management in certain scenarios. Lisinopril is an ACE inhibitor that lowers BP by preventing angiotensin II formation, reducing vasoconstriction and aldosterone-mediated sodium retention. Metoprolol is a beta-blocker that lowers BP mainly by reducing heart rate and renin release. Albuterol is a bronchodilator, not a diuretic or a blood pressure–lowering agent.
