Crestor belongs to a group of medicines called HMG - CoA reductase inhibitors (also known as “statins’). CRESTOR is used to lower high levels of blood fats which are called lipids, usually when changes to diet and exercise have failed to do this. CRESTOR, in addition to diet, lowers “bad” cholesterol (LDL - C) and increases “good” cholesterol (HDL - C) in the blood. In adult patients who have an increased risk of cardiovascular disease, CRESTOR has been shown to reduce non - fatal heart attacks, non - fatal strokes and procedures such as stents and bypass surgery for heart disease.
