ScienceDaily (Apr. 29, 2008) — A widely used class of diabetes medications appears to be associated with an increased risk for fractures, according to a new article. “The insulin-sensitizing thiazolidinediones are a relatively new and effective class of oral antidiabetic agents that have gained wide use in clinical conditions characterized by insulin resistance,” the authors write as background information in the article. Two drugs in this category, pioglitazone and rosiglitazone, account for 21 percent of oral diabetes medications prescribed in the United States and 5 percent of those in Europe. Recent studies have suggested that these therapies may have unfavorable effects on bone, resulting in slower bone formation and faster bone loss. Christian Meier, M.D., of University Hospital Basel, Basel, Switzerland, and colleagues studied 1,020 patients with diabetes who had fractures diagnosed at British general practitioners’ offices between 1994 and 2005. For each of those patients, up to four control patients with diabetes who were the same age and sex and had the same physician but did not have fractures were selected, for a total of 3,728 matched controls.
