Ezetimibe (pronounced /ɛˈzɛtəmɪb/) is an anti-hyperlipidemic medication which is used to lower cholesterol levels. It acts by decreasing cholesterol absorption in the intestine. It may be used alone when other cholesterol-lowering medications are not tolerated, or together with statins (e.g. ezetimibe/simvastatin) when cholesterol levels are unable to be controlled on statins alone. It is marketed by Schering-Plough and Merck under the trade names Ezetrol, Zetia and Ezemibe. Ezetimibe was originally discovered by a team of four Schering-Plough research chemists; Drs. Stuart B. Rosenblum, Duane A. Burnett, John W. Clader and Brian A. McKittrick.
Additional recommended knowledge
Ezetimibe localises at the brush border of the small intestine, where it inhibits the absorption of cholesterol from the diet. Specifically, it appears to bind to a critical mediator of cholesterol absorption, the Niemann-Pick C1-Like 1 (NPC1L1) protein on the gastrointestinal tract epithelial cells as well as in hepatocytes. In addition to this direct effect, decreased cholesterol absorption leads to an increase in LDL-cholesterol uptake into cells, thus decreasing levels in the blood plasma.
Ezetimibe is indicated as an adjunct to dietary measures in the management of:
Common adverse drug reactions (≥1% of patients) associated with ezetimibe therapy include: headache and/or diarrhea. Infrequent adverse effects (0.1–1% of patients) include: myalgia and/or raised liver function test (ALT/AST) results. Rarely (<0.1% of patients), hypersensitivity reactions (rash, angioedema) or myopathy may occur.
