 Lipids Online Slides: ezetimibe, lipid metabolism, mechanism of action
It is important to consider that ezetimibe therapy may lead to increased LDL receptor expression in individuals with functional LDL receptors, and that this may comprise a component of the mechanism by which ezetimibe lowers plasma LDL cholesterol and triglyceride concentrations.
Ezetimibe is the first in the class of cholesterol absorption inhibitors, whose mechanism of action is consistent with the binding to and blockade of the putative sterol transporter on the brush border membrane of intestinal epithelial cells.
Ezetimibe undergoes glucuronidation in the intestine, and both ezetimibe and its active glucuronidated derivative/metabolite circulate enterohepatically (between the intestine and the liver) resulting in repeated delivery to the intestine (the site of pharmacologic action).
