Lipitor (atorvastatin) is in a group of drugs called HMG CoA reductase inhibitors, or statins. Atorvastatin 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).
rnLipitor is used to treat high cholesterol. Lipitor is also used to lower the risk of stroke, heart attack, or other heart complications in people with type 2 diabetes, coronary heart disease, or other risk factors.
rnLipitor is used in adults and children who are at least 10 years old.
