Judge blocks federal funding of human embryonic stem cell research

Rosiglitazone, sold under the trade name Avandia by GlaxoSmithKline, and pioglitazone, sold as Actos by Takeda Pharmaceuticals, belong to the same class of drugs, called TZDs or thiazolidinediones. They help the body use insulin more effectively by boosting the body's sensitivity to the hormone and thus help control blood sugar.

This study has results different from earlier ones that found a greater risk of heart attack among rosiglitazone users compared to patients on other treatments or placebo. In 2007, the Food and Drug Administration decided that the benefits of rosiglitazone outweighed the risks, and it remained on the market although its use decreased significantly. In July 2010, an FDA advisory committee again reviewed numerous studies, including this study, and recommended that rosiglitazone remain on the market, although with additional warnings or restrictions. The FDA has not yet ruled on this latest recommendation.

"Besides its findings that rosiglitazone and pioglitazone have comparable risks, what distinguishes this latest study from other claims-based analyses is its analysis of death records, which include out-of-hospital deaths," Wertz said. The study also followed patients for a longer period of time than some of the earlier research, according to the investigators.

"One of the reasons we embarked on this analysis was to see if there were any differences in effect that we could identify between these two agents," said Mark J. Cziraky, Pharm.D., study co-author, and vice president of research development and operations at HealthCore. "We did not find that with the approach and methods we took within this population."
