Delaware Attorney General Matt Denn on Friday sued a contingent of leading pharmaceutical manufacturers, distributors and pharmacies in an effort to hold them liable for their alleged role in the state's opioid epidemic.

The 124-page complaint accuses the companies, including Purdue Pharma Inc., CVS Health Corp. and Walgreens Boots Alliance Inc., of using deceptive marketing tactics to increase opioid sales and allowing painkillers to be used for unapproved purposes.

The suit, filed in Delaware Superior Court's Complex Commercial Litigation Division, seeks compensatory damages to reimburse the state for the cost of battling the crisis through health care, the criminal justice system, social services, welfare and education systems.
