Which medication is used as a diuretic?

Furosemide is recognized as a loop diuretic and is commonly prescribed to eliminate excess fluid from the body by promoting urine production in the kidneys. It is particularly effective in treating conditions such as heart failure, renal disease, and hypertension. This medication works by inhibiting salt reabsorption in the loop of Henle within the nephron, leading to increased excretion of sodium and water.

While other medications in the list have specific roles, they are not classified as diuretics. Clopidogrel is an antiplatelet agent, predominantly used to prevent blood clots. Losartan is an angiotensin receptor blocker (ARB) primarily used to treat high blood pressure and certain heart conditions. Metoprolol is a beta-blocker utilized for hypertension, heart failure, and arrhythmias. Therefore, furosemide stands out as the appropriate choice for a diuretic due to its established mechanism and clinical applications in fluid management.
