Actos and Avandia News

A large study from British Columbia, Canada is pointing to an increased fracture risk with thiazolidinediones (TZDs), used in the treatment of type 2 diabetes [1]. The study, which reviewed fracture risk in more than 84 000 patients receiving either rosiglitazone (Avandia, GlaxoSmithKline) or pioglitazone (Actos, Takeda) vs a sulfonylurea, found that both men and women are at increased risk of broken bones when taking a TZD and hints that pioglitazone may be more strongly associated with fracture risk. Two years ago, the FDA requested that a warning on fracture risk be added to the pioglitazone labeling.

The study appears in the August 10/24, 2009 issue of the Archives of Internal Medicine.

"Larger observational studies are needed, and fracture data from clinical trials need to be fully published so that fracture risks can be known with greater certainty," Dr Colin R Dormuth (University of British Columbia, Vancouver) and colleagues write.

Dormuth et al point out that the research linking fractures to TZD use has not been entirely consistent, with some trials (but not all) suggesting different effects for the two commercially available TZDs and others pointing to a different degree of risk according to gender.
