OxyContin maker Purdue Pharma LP filed for bankruptcy protection Sunday night, succumbing to pressure from more than 2,600 lawsuits alleging the company helped fuel the deadly U.S. opioid epidemic.

Purdue's board met Sunday evening to approve the long-expected bankruptcy filing, which the company is pursuing to restructure under terms of a proposal to settle the widespread litigation.

Purdue, which filed for Chapter 11 protection in a federal bankruptcy court in White Plains, New York, reached a tentative deal to resolve lawsuits with 24 states and five U.S. territories, as well as lead lawyers for more than 2,000 cities, counties and other plaintiffs, the company said.
