Pharmaceutical The US Justice Department is investigating Abbott Laboratories‘ sales and marketing activities for its anti-seizure drug Depakote (divalproex), its third top-selling drug, the US health care major revealed in a regulatory filing. It said that the US Attorney for the Western District of Virginia is seeking to determine whether Abbott‘s marketing activities violated civil or criminal laws, including the Federal False Claims Act, the Food and Drug Cosmetic Act, and the Anti-Kickback Statute "in connection with Medicare and/or Medicaid reimbursement to third parties."Abbott spokeswoman Adelle Infante said the company is cooperating with the investigation, but declined further comment. Sales of Depakote, which is approved to treat bipolar disorder and seizures and to prevent migraine headaches, have been declining recently due to generic competition. They plunged 70% to $354 million for the first nine months of 2009, having reached annual revenues of around $1 billion previously. 9 November 2009
