Brief Summary
The purpose of this study is to investigate the effects of the two lipid -lowering drugs, ezetimibe and simvastatin, on lipid metabolism in humans. In specific, the study will investigate in blood cells whether the enzyme that controls cholesterol synthesis, HMG-CoA reductase, and the receptor that takes up cholesterol from the blood, the LDL receptor, are changed during treatment with the aforementioned drugs.
