July 30, 2007 -- An FDA advisory panel said Monday the diabetes drug Avandia
should remain on the U.S. market, despite widespread concerns that it raises
the risk of heart attacks.
Experts overwhelmingly expressed confidence that the drug, also called
rosiglitazone, boosts the risk of heart attack and other dangerous heart
problems. But they then voted 22-1 to urge the FDA to allow continued sales to
But those continued sales are likely to carry significant new warnings about
who can safely use Avandia. Several experts said the FDA should consider either
stark new "black box" warnings on Avandia or other restrictions that
could limit its availability in patients with heart disease.
"We certainly sent I think a clear signal that there's going to be
changes in the way this is promoted ... and certainly in how physicians use this
drug," Clifford Rosen, MD, the panel's leader, said after the decision.
The decision came despite calls from some FDA officials to pull Avandia from
the U.S. market.
"A wrong decision will cost thousands of lives," said David Graham,
MD, an FDA safety officer who urged Avandia be removed.
But officials from GlaxoSmithKline, Avandia's manufacturer, pointed out that
no studies had shown that patients taking Avandia were more likely to die of
heart problems than those taking another drug or a placebo.

mortality," said Ronald Krall, MD, the company's chief medical officer.

of medicine at the University of New Mexico School of Medicine and a member of
the advisory panel.
Avandia is an oral medication used by patients with type 2 diabetes to help
control blood sugar. Millions of patients have taken Avandia, as well as a
similar drug called Actos, or pioglitazone.
