Background:

Ezetimibe is a potent and novel inhibitor of cholesterol absorption [1].


Cholesterol is a lipid molecule and is required to build and maintain membranes structural integrity and fluidity. Also, it serves as a precursor of vitamin D, bile acids and steroid hormones.


In differentiated Caco-2 cells incubated with a carotenoid (1 μM), ezetimibe (10 mg/L) inhibited carotenoid transport with 50% inhibition for ɑ-carotene and β-carotene. Also, it inhibited the transport of β-cryptoxanthin, lycopene and lutein:zeaxanthin(1:1). At the same time, ezetimibe inhibited cholesterol transport by 31%. Ezetimibe decreased the expression of the surface receptors SR-BI, ATP binding cassette transporter, subfamily A (ABCA1), Niemann-Pick type C1 Like 1 protein (NPC1L1) and retinoid acid receptor (RAR)γ, sterol-regulatory element binding proteins SREBP-1 and SREBP-2, and liver X receptor (LXR)β [3].


In apolipoprotein E knockout (apoE-/-) mice, ezetimibe (3 mg/kg) inhibited cholesterol absorption by 90%. Ezetimibe reduced plasma cholesterol, increased HDL levels, and inhibits the progression of atherosclerosis [1]. In phase III human trials, Ezetimibe (10 mg) significantly reduced the levels of LDL cholesterol, total cholesterol and triglycerides and increased the level of HDL cholesterol [2].
