Which medication is marketed under the name Zetia?

The medication marketed under the name Zetia is Ezetimibe. Ezetimibe is an antihyperlipidemic agent that works by inhibiting the absorption of cholesterol from the intestines, thus helping to lower overall cholesterol levels in the body. It is specifically indicated for the treatment of hyperlipidemia, often used in conjunction with a healthy diet to reduce LDL cholesterol. This mechanism of action makes Ezetimibe valuable in managing cholesterol levels, particularly for patients who may be at risk for cardiovascular diseases.

The other medications listed are used for different therapeutic purposes. Crestor is a statin used for lowering cholesterol and managing cardiovascular risk, Cozaar is an antihypertensive that belongs to the class of angiotensin receptor blockers, and Calan is primarily used for managing conditions like high blood pressure and certain types of cardiac dysrhythmias. Each of these medications has its unique indications and mechanisms of action, which differentiates them from Ezetimibe, reinforcing why Ezetimibe is the correct answer to the question.
