Lipitor is the brand name for atorvastatin, which is a medication used to lower cholesterol levels in the blood. Atorvastatin is the generic name for Lipitor, and it is available in the market as a generic medication. Therefore, Lipitor is not the only generic option available for atorvastatin. There are other generic versions of atorvastatin available in the market, which are approved by the FDA and are available at a lower cost than the brand name Lipitor. These generic versions are also considered to be equally effective and safe as the brand name medication [1][2][3].
