Updated lawsuit teases new details against OxyContin maker

Stamford, Connecticut-based Purdue Pharma has denied the allegations.

In a statement Saturday, the company called Massachusetts' updated complaint "irresponsible and inaccurate," adding that "Purdue and the individual defendants will aggressively defend against these misleading allegations."

OxyContin has been the world's top-selling opioid painkiller, generating billions of dollars for Purdue Pharma. In February, the company announced it was eliminating half of its sales force and would no longer market the drug to doctors.

The company is now defending lawsuits from several states and local governments. Earlier this week, Connecticut Attorney General George Jepsen said the state will be suing Purdue Pharma and several of the company's current and former officials on allegations their marketing of the painkiller helped drive the nation's opioid crisis.

The drugmaker has faced legal challenges over its painkillers before.

In 2007, it agreed to pay $19.5 million to settle lawsuits with 26 states, including Massachusetts, and the District of Columbia that claimed Purdue aggressively marketed OxyContin to doctors while downplaying the risk of addiction. Purdue did not admit wrongdoing as part of that settlement.
