Doctors claim Glaxo dismissed worries on Avandia

In 2007, after news broke that the diabetes drug Avandia was linked to a high risk of heart attacks, reports that the drug's maker had tried to stifle safety questions from a prominent Duke University researcher years earlier provoked a furor. Now it turns out that the Duke researcher wasn't alone in suggesting a tie to heart problems. A doctor from a small Maryland hospital linked Avandia to congestive heart failure in 2000, but the drug's maker, GlaxoSmithKline PLC, rejected her warning and tried to make her stop talking about it with other doctors and hospitals.
