Oklahoma Attorney General Mike Hunter is suing more than a dozen U.S. drug manufacturers.
The lawsuit names Purdue Pharma, Inc., Allergan PLC, Cephalon, Inc., Teva Pharmaceuticals USA, Inc., and Janssen Pharmaceuticals, Inc. among other companies. It was filed in Cleveland County District Court Friday morning.
The suit argues the companies were "deceptive" and "misleading" when marketing opioids to Oklahoma doctors, by exaggerating the drugs’ effectiveness and downplaying the danger of opioid addiction.
