Mallinckrodt Plc’s Questcor Pharmaceuticals Inc. faces a multistate antitrust investigation, according to a Texas attorney general’s office letter revealing that state’s participation in the probe.
The inquiry may expand on existing investigations by federal prosecutors and regulators. Texas said that, as of last month, it “anticipated being involved” in the multistate case, according to the June 12 letter, a response to a freedom of information request in May.
