Atorvastatin, marketed by Pfizer as a calcium salt under the trade name Lipitor, is a member of the drug class known as statins, used for lowering blood cholesterol.
Atorvastatin also stabilizes plaque and prevents strokes through anti-inflammatory and other mechanisms. Like all statins, atorvastatin works by inhibiting HMG-CoA reductase, an enzyme found in liver tissue that plays a key role in production of cholesterol in the body.
