It 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. Atorvastatin was first synthesized in 1985 by Bruce Roth while working at Parke-Davis Warner-Lambert Company (now Pfizer). With 2008 sales of US$12.4 billion, Lipitor was the top-selling branded pharmaceutical in the world. U.S. patent protection was scheduled to expire in June 2011.
