Lipitor

FILE - In this June 14, 2011 file photo, the drug Lipitor is displayed at Medco Health Solutions Inc., in Willingboro, N.J. Lipitor, the best-selling drug ever, was viewed as such an also-ran that it almost didn't make it into patient testing. But Lipitor reigned for nearly a decade as the top-selling drug. It's set to be toppled after getting its first generic rivals four weeks ago. (AP Photo/Matt Rourke, File)
