Crestor (rosuvastatin) belongs to a a group of drugs called HMG CoA reductase inhibitors, or “statins.” Rosuvastatin reduces levels of “bad” cholesterol (low-density lipoprotein, or LDL) and triglycerides in the blood, while increasing levels of “good” cholesterol (high-density lipoprotein, or HDL).
Crestor is used to lower cholesterol and triglycerides (types of fat) in the blood and to slow the build-up of plaque (fatty deposits) in your blood vessels. Crestor is also used to lower the risk of stroke, heart attack, and other heart complications in certain people with diabetes, coronary heart disease, or other risk factors.
