Lipitor, known generically as Atorvastatin Calcium tablets, are a type of cholesterol-lowering medicine called a statin, which block an enzyme in the liver that the body uses to make cholesterol.
Lipitor can lower the risk for heart attack, stroke, certain types of heart surgery, and chest pain in patients who have heart disease or risk factors for heart disease such as age, smoking, high blood pressure, low HDL, or family history of early heart disease.
Pfizer has filed the lawsuit against the Indian drug maker in December 2009 for blocking generic copies of Lipitor which infringe Pfizer’s patent for the tablets to be expire in 2017.
