Which medication is primarily used to treat hypertension and is referred to as Losartan?

Losartan is recognized primarily as a medication used to manage hypertension, and its brand name is Cozaar. This medication belongs to a class of drugs known as angiotensin II receptor blockers (ARBs), which effectively lower blood pressure by relaxing blood vessels, making it easier for the heart to pump blood.

Understanding its role in treating hypertension is crucial, as maintaining healthy blood pressure levels is vital for reducing the risk of cardiovascular complications. The specific mechanism of action of Losartan helps in preventing the constriction of blood vessels, thus promoting better blood flow and lower pressure.

Other options listed, while they also have specific uses, do not relate to hypertension treatment in the same way that Losartan does. Each alternative medication serves different purposes: Crestor is primarily used for lowering cholesterol, Calan is a calcium channel blocker often used for treating angina and hypertension but is not referred to as Losartan, and Zetia is a cholesterol absorption inhibitor. Thus, the importance of Losartan as a specific treatment for hypertension is clearly highlighted by its brand name, Cozaar.
