Rosiglitazone (roe" si gli' ta zone) an insulin sensitizing agent that improves glucose control in patients with type 2 diabetes. Like other thiazolidinediones, it is thought to act by engagement of PPAR-? receptors which induce multiple genes involved in glucose and fatty acid metabolism. In clinical trials, rosiglitazone was found to lower blood glucose and HbA1c levels and had additive effects with the sulfonylureas and metformin.

Rosiglitazone was approved for use in the United States in 1999. While the initial thiazolidinedione – troglitazone – had been associated with high rates of serum aminotransferase elevations and multiple reports of severe liver injury and death from acute liver failure, rosiglitazone was associated with a lower rate of ALT elevations and with only rare instances of clinically apparent liver injury. Rosiglitazone is approved as an adjunct to diet and exercise in the glycemic control of patients with type 2 diabetes.
