Pharmaceutical giant GlaxoSmithKline Plc was the drug industry's top ad spender in 2006, relentlessly hawking its asthma and diabetes potions, but some important info did not make it into the
company's campaigns.
For instance, Glaxo knew its Avandia diabetes pill could cause heart and circulatory complications problems eight years ago when it won federal approval, but the
concerns weren't really disseminated until late last month, when the Cleveland Clinic Foundation reported it has a 43% higher risk of heart attacks than other drugs.
Glaxo had its own,
similar data that Avandia raised the risk of heart attacks by 31% and while it gave the information to U.S. regulators and put it on its Web site last year -- amid more than 2,000 studies -it didn't
make much noise about it.
The company claims the heart-risk studies, including its own, are flawed. "Why would you publicize it?," says Glaxo Chief Executive Officer Jean-Pierre
Garnier. "We don't publicize every submission we make to the Food and Drug Administration."
