Today’s NY Times carries a front page article about the dangers of Actos and Avandia, two popular diabetes medications. The reason behind the news story is that the FDA has finally required the two companies that make these diabetes drugs to carry a “black box” warning (the strongest labeling warning that can be applied) about the potential for congestive heart failure (overload of fluid in the heart and lungs) in diabetics using these drugs. Is this warning really news? Not to doctors.
I have been to numerous seminars on the use of these two diabetes drugs and have been paid by the companies that manufacture these drugs to educate other health care professionals about the use and hazards of these drugs. Both companies gave all representatives and speakers the strictest instructions regarding their obligation to carefully mention the potential for fluid overload and congestive heart failure associated with the use of these drugs. I know that my colleagues, particularly the cardiologists (heart doctors) and endocrinologists (diabetes doctors), have been acutely aware of this information for years.
Did you know that the type of drugs known as sulfonylureas that have been used to treat diabetes since the 1960’s and remain popular today carry a “black box” warning since the 1970’s about the potential for causing heart disease? This class of drug include Diabinese, Orinase, DiaBeta, Micronase, glyburide, and glipizide. Why are these drugs still in widespread use, and where are the stories notifying the public about this? What’s the big deal about the black box warning on Actos and Avandia?
I think I smell some politics going on. The Commissioner of the FDA, Dr. von Eschenback, was appointed by President Bush in 2005. The harshest critics of the FDA on this issue are the Democrats on the House Panel. Coming out of the woodwork are various “injured” parties who were criticised by company representatives for speaking out against these drugs in 1999. These stories warrant a separate column in The Times today.
Are there real risks to taking Actos and Avandia in the treatment of diabetes. Of course there are, just as there is a real risk of treating diabetes with just about any drug. It is up to the medical profession to remain vigilant and educated about these risks and to balance them with the benefits. Inflammatory front page news stories which create an atmosphere of mistrust and hysteria may serve only narrow political purposes.
