Question

which of the following drugs is a cholesterol absorption inhibitor?
fenofibrate
nicotinic acid
warfarin
ezetimibe

Explanation:

Fenofibrate is a fibrate used for lipid - lowering by activating peroxisome proliferator - activated receptor - alpha. Nicotinic acid (niacin) is used to reduce LDL and increase HDL by multiple mechanisms. Warfarin is an anticoagulant, not related to cholesterol absorption. Ezetimibe specifically inhibits cholesterol absorption at the intestinal brush border.

Ezetimibe
