Purdue Pharma, the pharmaceutical company behind OxyContin, has obtained the support of 55 U.S. state and territorial attorneys general for its $7.4 billion opioid settlement, a significant milestone in one of the largest mass tort cases in U.S. history. The agreement seeks to resolve thousands of lawsuits related to the opioid epidemic, which has claimed hundreds of thousands of lives and placed substantial economic burdens on state healthcare systems.
