Ezetimibe（Cat No.:A000268）is a lipid-lowering medication with the molecular formula C24H21F2NO3, used to reduce blood cholesterol levels. It works by selectively inhibiting the Niemann-Pick C1-Like 1 (NPC1L1) protein in the small intestine, blocking dietary and biliary cholesterol absorption without affecting triglycerides or fat-soluble vitamins. Ezetimibe is commonly prescribed alone or in combination with statins to treat hypercholesterolemia and reduce cardiovascular risk. It is well-tolerated, taken orally, and minimally metabolized by the liver. Its targeted mechanism makes it a valuable option for patients requiring non-statin or adjunctive cholesterol-lowering therapy.
