The Minnesota Senior Federation is hoping the lawsuit will be certified as a class-action.
The federal lawsuit names Pfizer, GlaxoSmithKline, Abbott Laboratories, AstraZeneca, Boehringer Ingelheim, Eli Lilly, Merck, Novartis and Wyeth Pharmaceuticals. It claims the companies conspired to try to block the supply of name-brand drugs to Canadian pharmacists that sell to US citizens.
Pfizer says its practices comply with U.S. law and federal regulations. GlaxoSmithKline says it didn't act with other companies. The other defendants either declined to comment or didn't return calls.
The federation says its lawsuit represents a new phase in the group's efforts to make it easier to import drugs at lower Canadian prices.
