Merck & Co., Inc.

Drug Names(s): Ezetrol, Zient, Absorcol, ezetimibe, SCH 58235

Description: Zetia (ezetimibe) lowers cholesterol by localizing at the brush border of the small intestine to inhibit cholesterol absorption. This mechanism of action makes Zetia complementary to statins, which work by inhibiting cholesterol synthesis in the liver.

Zetia is metabolized to an active glucuronide metabolite, which is even more potent. Repeated enterohepatic circulation of the metabolite leads to a long duration of action.

The specific molecular target for Zetia is thought to be Niemann–Pick C1-Like 1 (NPC1L1), a protein critical for cholesterol absorption.
