Lipitor is a brand name for atorvastatin, a type of medication called a statin that is used to lower cholesterol levels in the blood. According to drugpatentwatch.com [1], the patent for Lipitor expired in 2011, which means that generic versions of atorvastatin are now available. These generic versions are typically less expensive than the brand name drug.
