A group of seven drug plans has filed a class action lawsuit against Pfizer Inc., claiming the company used off-label promotion of atorvastatin (Lipitor) to boost sales. According to New York-based Grant & Eisenhofer, P.A., the securities litigation firm representing the group, the plaintiffs contend that Pfizer's physician and hospital marketing materials have misrepresented treatment protocols established by the National Cholesterol Education Program's Adult Treatment Panel III (ATP III), and that the drug was approved by the FDA only for use in accordance with ATP III.
