Attorney General Michael Delaney says the state of New Hampshire will get nearly $4 million from British drug maker GlaxoSmithKline as part of the largest health care fraud settlement in US history. Delaney announced New Hampshire’s share of the $3 billion settlement Tuesday, a day after the Justice Department said GlaxoSmithKline PLC will plead guilty to promoting popular antidepressants Paxil and Wellbutrin for unapproved uses. The company also will plead guilty to failing to report some safety problems with diabetes drug Avandia, which was restricted in the United States and banned in Europe after it was found in 2007 to sharply increase the risks of heart attacks and congestive heart failure. In addition to the fine, Glaxo agreed to resolve civil liability for promoting Paxil, Wellbutrin, and other drugs for unapproved uses.
