Purdue Pharma, the drug-maker owned by the billionaire Sackler family, has reached a $270m settlement in a lawsuit which claimed its opioids contributed to the deaths of thousands of people.
The deal with Oklahoma is the first settlement the US firm has struck amid some 2,000 other lawsuits it is facing linked to its painkiller OxyContin.
Purdue is one of three companies named in the claim that alleged they used deceptive practices to sell opioids.
Purdue Pharma declined to comment.
