title: Changes in glitazone use among office-based physicians in the U.S., 2003-2009.
abstract: OBJECTIVE
  Little is known regarding recent changes in glitazone use.
  
  
  METHODS
  Interrupted time series analyses of nationally representative office-visit data using IMS Health's National Disease and Therapeutic Index.
  
  
  RESULTS
  From 2003 through 2005, glitazone use increased steadily. From February 2005 to January 2007, rosiglitazone use decreased by 16% (95% CI -20 to -11) annually; pioglitazone use increased at an annual rate of 14% (9-18). During a period of Food and Drug Administration (FDA) advisories, rosiglitazone use declined sharply from 0.42 million monthly treatment visits (February 2007) to 0.13 million monthly visits (May 2008). Pioglitazone use remained stable, accounting for approximately 5.8 million physician visits (77% of all glitazone use) where a treatment was used during the final 12 months of observation.
  
  
  CONCLUSIONS
  The combined effect of scientific publications, advisories, and media exposure was associated with a substantial decrease in rosiglitazone use. Despite a class-level FDA advisory, pioglitazone use was not similarly affected.
