Ezetimibe is a unique inhibitor of intestinal cholesterol absorption. Ezetimibe selectively inhibits intestinal cholesterol absorption by blocking Niemann-Pick C1-like 1 (NPCIL1). Ezetimibe accelerates VLDL and TG degradation. Therefore, ezetimibe ameliorates postprandial hyperlipidemia. Ezetimibe inhibited the progression of nonalcoholic fatty liver disease (NAFLD) by correcting insulin resistance and decreasing small dense LDL-C in human subjects. In clinical study, ezetimibe administration combined with statin failed to inhibit progression of IMT thickness in ENHANCE (Ezetimibe and Simvastatin in Hypercholesterolemia Enhances Atherosclerosis Regression) study. In this study baseline IMT thickness (0.7 mm) of patients was within normal range. Therefore only two years observation was too short to demonstrate anti-atherogenic effects of ezetimibe. SEAS(Simvastatin and Ezetimibe in Aortic Stenosis) trial examined effects of combination therapy with ezetimibe and statin in patients with aortic stenosis. Combination therapy could not inhibit progression of aortic stenosis. However, events of ischemic heart disease, especially CABG were significantly decreased only in combination group. Statin was not reported to reduce CVD(cardiovascular disease) in moderate to severe CKD patients. In SHARP(Study of Heart and Renal Protection) study, patients with severe renal disease were allocated either for statin alone group or combination therapy group with statin and ezetimibe. Combination therapy significantly decreased non-hemorrhagic stroke by 25 % compared with statin alone group in severe CKD and HD(hemodialysis) patients. Ezetimibe has unique lipid lowering profile increasing HDL-C concomitant with decreasing LDL-C and TG. Ezetimibe should be initiated first in patients with insulin resistant metabolic syndrome. Ezetimibe should be combined with statin to reduce not only LDL-C but RLP-C(remnant like lipoprotein particle choletserol) in type IIb dyslipidemia.

Hyperlipidemia is a risk factor for atherosclerosis. Raised low-density lipoprotein cholesterol (LDL-C) and lipoprotein(a) levels are severe risk factors for atherosclerosis. The role of high-density lipoprotein cholesterol (HDL-C) is controversial. Total cholesterol, LDL-C, HDL-C, triglycerides and lipoprotein(a) levels should be determined in a fasting state. The basis of treating hyperlipidemia remains diet, physical exercise and weight reduction. Olive oil and nuts have been shown to be beneficial. Statins remain first line drug treatment. Further treatment options are ezetimibe, bile acid sequestrants, fibrates and fish oil. Side effects of statins include myopathies and, as shown during the last years, also an increased risk of diabetes mellitus. In patients with statin-related myopathies first results of a gene analysis have been published showing a means of predicting which statin can be administered at which dose for the individual patient with least risk of side effects. Most convincing data have been shown for simvastatin. Patients with renal insufficiency have been shown to have a raised cardiovascular risk. In the SHARP Study the combination of simvastatin plus ezetimibe was effective in reducing cardiovascular events in patients with severe renal insufficiency (especially before dialysis but also in dialysis dependent patients). Important aspects of treating patients with chylomicronemia syndrome are illustrated. Treating young patients with hyperlipidemia as primary prevention remains problematic.
