Ezetimibe/atorvastatin (trade namesLiptruzet,Atozet) is a cholesterol loweringcombination drug.[1] In the United States, it was approved in May 2013, by theFood and Drug Administration for the treatment of elevatedlow-density lipoprotein (LDL) in patients with primary or mixedhyperlipidemia asadjunctive therapy to diet.[2] It has also been approved to reduce elevated total cholesterol and elevated LDL in patients diagnosed with homozygous familial hypercholesterolemia as an adjunctive treatment to other hyperlipidemia treatments.[3]
Some cardiologists opposed the approval, because the combination reduced LDL cholesterol in a clinical trial, but it did not reduce heart disease. A clinical trial studying the endpoints of heart attacks, strokes and heart-related deaths is scheduled to conclude in 2014.[4]
Liptruzet was withdrawn from sale by its manufacturer in June 2015, but not for reasons of safety or effectiveness.[5]
This combination drug works to reduce cholesterol levels through two different pathways. Theezetimibe component of the medication works by inhibiting cholesterol absorption from food while theatorvastatin component inhibits intrinsic cholesterol production in the liver.[6]
Women that are pregnant or may become pregnant should not use the drug. It is a teratogenic agent that may disrupt the growth and development of a fetus. Immediate discontinuation is recommended in patients that become pregnant while taking this drug.
