Louisiana filed several lawsuits accusing pharmaceutical giant CVS of abusing customer information and using its market position to drive up drug costs and unfairly undermine independent pharmacies, the state’s attorney general said Tuesday.

Attorney General Liz Murrill began investigating CVS after the company sent out mass text messages to thousands of residents June 11 to lobby against legislation that took aim at its business structure. The texts warned that medication costs could go up and all CVS pharmacies in the state would close.

The lawsuits were filed Monday. Two other lawsuits allege that CVS artificially inflates prices for consumers and independent pharmacies. CVS has denied any wrongdoing. — Associated Press
