How it Works
Crestor belongs to a class of drugs known as HMG CoA reductase inhibitors, or statins. Statins basically reduce the levels of "bad" cholesterol i.e. low-density lipoprotein(LDL) as well as triglycerides, while increasing the blood levels of good high-density lipoprotein (HDL) cholesterol in the body. Crestor blocks the enzyme HMG-CoA reductase, thereby inhibiting the production of cholesterol in the liver.
