Rosiglitazone, from Hero to Zero.



























In the years that followed the launch of rosiglitazone, there were many papers on its usefulness for patients with diabetes. There were papers that showed the drug’s effectiveness in reducing blood sugar when used alone example and also when used in combination with sulphonylureas example or metformin example . Some other notable trials that showed beneficial effects of rosiglitazone were the DREAM trial and the ADOPT trial. In the DREAM trial investigators showed that rosiglitazone could reduce the development of diabetes in those who had impaired fasting glucose or impaired glucose tolerance while the ADOPT trial showed that rosiglitazone was better than metformin or a sulphonylurea in maintaining glycemic control as monotherapy.
