FDA:No elevated risk of heart attack or death in patients on Avandia

Image
The U.S. Food and Drug Administration today announced it is requiring the removal of certain restrictions on prescribing and use of the diabetes drug Avandia (rosiglitazone) to reflect new information regarding the cardiovascular risk of the medicine. Today’s actions are consistent with the recommendations of expert advisory committees. Results from the Rosiglitazone Evaluated for Cardiovascular Outcomes and Regulation of Glycemia in Diabetes (RECORD) clinical trial showed no elevated risk of heart attack or death in patients being treated with Avandia when compared to standard-of-care diabetes drugs. These data do not confirm the signal of increased risk of heart attacks that was found in a meta-analysis of clinical trials first reported in 2007. In addition to Avandia, rosiglitazone is available in combination with other diabetes medications, including metformin under the brand name Avandamet and glimepiride under the brand name Avandaryl.  http://www.fda.gov/Ne
