avandia

The U.S. Food and Drug Administration announced today that the manufacturer of Avandia (rosiglitazone), a drug used to treat type 2 diabetes, has agreed to add new information to the existing boxed warning in the drug's labeling about potential increased risk for heart attacks.

Avandia, manufactured by GlaxoSmithKline (GSK), Philadelphia, Pa., was approved in 1999 as an adjunct to diet and exercise to improve control of blood sugar levels. Avandia is approved to be used as a single therapy or used in combination with metformin and sulfonylureas, other oral anti-diabetes treatments.
