 The purpose of the study is to investigate the effects of atorvastatin Lipitor and rosuvastatin Crestor, United States Food and Drug Administration FDA approved drugs commonly prescribed by doctors to lower cholesterol, on certain functions of platelets cells that cause blood clots, white blood cells cells that are responsible for inflammation, and blood flow regulation by arteries. This is important because we are looking at ways to more effectively prevent atherosclerosis plaque buildup in blood vessels and heart disease. Many studies have demonstrated that these drugs are effective at reducing inflammation and stabilizing plaques. We are interested in better understanding the effects of these medicines on inflammation pain and swelling and the mechanism by which they act.
