Both losartan and furosemide are used to treat high blood pressure, but they belong to two different classes of medications tha work by entirely different mechanisms. Understanding these differences is crucial to understanding their uses and effects.
Losartan Tablets Ingredients
Losartan tablets contain the active ingredient losartan, 50 mg per tablet in this example. Losartan is an angiotensin II receptor blocker (ARB). It works by blocking the effect of angiotensin II, a substance that constricts blood vessels and increases the secretion of aldosterone, which leads to high blood pressure and fluid retention.
Furosemide Tablets Ingredients
Furosemide tablets contain the active ingredient furosemide, 40 mg per tablet in this example. Furosemide is a loop diuretic. It works by blocking the reabsorption of sodium, chloride, and water in the loop of Henle in the kidneys, which increases urine excretion and reduces fluid volume in the body, thereby lowering blood pressure and reducing edema.
