Losartan, the active ingredient in Cozaar, operates by selectively blocking the binding of angiotensin II to the AT1 receptor found in many tissues (e.g., vascular smooth muscle, adrenal gland). By inhibiting this action, losartan effectively reduces vasoconstriction and aldosterone secretion, decreasing blood pressure and reducing the risk of related health conditions. Cozaar is thus a vital medication for patients with hypertension or those who are at risk of developing complications from high blood pressure and diabetes.

Cozaar, known by its generic name losartan, belongs to a class of medications referred to as angiotensin II receptor blockers (ARBs). It’s specifically designed to help lower blood pressure by blocking the action of angiotensin II, a chemical in the body that narrows blood vessels. This action helps to relax and widen blood vessels, making it easier for the heart to pump blood. Cozaar is primarily used to manage hypertension (high blood pressure) and to protect the kidneys from damage due to diabetes. By controlling high blood pressure, Cozaar helps prevent strokes, heart attacks, and kidney problems, thereby improving overall cardiovascular health.
