HMG CoA Reductase Inhibitors

Medications: HMG CoA Reductase Inhibitors | Niacin | Nitroglycerin Sublingual or Spray

Definition

These medications are packaged under the names Mevacor, Pravachol, Zocor, Lipator or Lescol. They block the production of cholesterol within cells, causing the cells to increase specific receptors on their surface that will take up LDL cholesterol particles from the blood. This effect is especially prominent in the liver, which is the organ that largely controls cholesterol in the body. As the number of LDL receptors increases, the levels of total and LDL cholesterol in the blood will go down.
