FDA: Popular Diabetes Drug Linked to Heart Attacks
The U.S. FDA announced today that it will significantly restrict the use of the diabetes drug Avandia (rosiglitazone) to patients with Type 2 diabetes who cannot control their diabetes on other medications. These new restrictions are in response to data that suggest an elevated risk of cardiovascular events, such as heart attack and stroke, in patients treated with Avandia, according to the FDA website.
“The FDA is taking this action today to protect patients, after a careful effort to weigh benefits and risks,” said FDA Commissioner Margaret A. Hamburg, M.D. “We are seeking to strike the right balance to support clinical care.”
Avandia, manufactured by GlaxoSmithKline (GSK), is in a class of drugs known as thiazolidinediones, or TZDs. It is intended to be used in conjunction with diet and exercise to improve glucose (blood sugar) control in patients with Type 2 diabetes mellitus.
Current users of Avandia who are benefiting from the drug will be able to continue using the medication if they choose to do so. Doctors will have to attest to and document their patients’ eligibility; patients will have to review statements describing the cardiovascular safety concerns associated with this drug and acknowledge they understand the risks.
“Allowing Avandia to remain on the market, but under restrictions, is an appropriate response, given the significant safety concerns and the scientific uncertainty still remaining about this drug,” said Janet Woodcock, M.D., director of the FDA’s Center for Drug Evaluation and Research.
