Crestor 20 mg Tablet 10 belongs to the statin class of medications, which reduces bad cholesterol (low-density lipoprotein-LDL) and glyceride levels, lowering the risk of future heart attack and stroke. When there is an excess of the unhealthy balance of cholesterol in the blood, high cholesterol, also known as hyperlipidemia or dyslipidemia, occurs.
