Lipitor (Atorvastatin calcium tablets) was brought into the market by Pfizer. Atorvastatin belongs to a class of drugs called statin, used for lowering blood cholesterol. The U.S. Food and Drug Administration (FDA) approved Lipitor in 1996. The drug works by blocking HMG-CoA reductase, the enzyme that allows the liver to produce LDL or "bad" cholesterol. It also stabilizes plaque and prevents stroke through its anti-inflammatory and other mechanisms.
Lipitor is prescribed to patients suffering from Dyslipidemia (abnormal amount of lipids like cholesterol and/or fat in the blood) and for prevention of cardiovascular disease.
Women in menopausal age taking Lipitor may be at a much greater risk for Diabetes because of the hormonal changes.
