Purdue Pharma’s negotiations to settle thousands of lawsuits over the company’s role in the opioids crisis have turned into a standoff between members of the Sackler family, who own the company, and a group of state attorneys general over how much the family should pay and whether it can continue selling drugs abroad.

The Sacklers are deep in negotiations that, if finalized, would force them to give up ownership of Purdue, the company widely blamed for the onset of the opioid epidemic with its aggressive marketing of the prescription painkiller OxyContin. But they want to keep selling OxyContin and other drugs abroad for as many as seven more years, through another company they own, Mundipharma, based in Cambridge, England.

Some attorneys general, particularly in wealthier states like New York, Massachusetts and Connecticut, are resisting that and other issues related to the foreign business.

“Connecticut demands that the Sacklers and Purdue management be forced completely out of the opioid business, domestically and internationally, and that they never be allowed to return,” s aid Attorney General William Tong of Connecticut .
