Here is a start, please add more:

An unit of PurduePharma, The PurdueFrederick Company, Inc. ("PurdueFrederick"), pleaded guilty in 2007 to misbranding OxyContin by falsely claiming that it was less addictive, less likely to be abused and diverted, and less likely to result in dependence and withdrawal than other painkillers. Additionally, PurduePharma and PurdueFrederick agreed to pay more than $600 million, of which more than $100 million was paid to resolve civil False Claims Act liability for willfully inducing the filing of false claims for OxyContin to Federal healthcare programs.

In connection with the resolution, PurduePhara and the Office of Inspector General of the Department of Health and Human Services agreed into a five-year Corporate Integrity Agreement (OIG-HHS).The corporate integrity agreement was closed by OIG-HIS in January 2013.
