In medicine, thiazolidinediones are "thiazoles with two keto oxygens. Members are insulin-sensitizing agents which overcome insulin resistance by activation of the peroxisome proliferator activated receptor gamma (PPAR-gamma)."[1] Thiazolidinediones are used for the treatment of diabetes mellitus type 2. Examples in include rosiglitazone and pioglitazone.

Effectiveness

The initial choice of anti-diabetic drug has been compared in a randomized controlled trial which found "cumulative incidence of monotherapy failure at 5 years of 15% with rosiglitazone, 21% with metformin, and 34% with glyburide."[2]

Pioglitazone, an insulin sensitizer, may reduce atherosclerosis compared to sulfonylureas which are insulin secretagogues.[3]

Adverse effects

Cardiac

Rosiglitazone may increase risk of death from cardiovascular causes.[4]

Rosiglitazone had more weight gain and edema.[2] Thiazolidinediones may increase the risk of heart failure.[5]

Fractures

Long term use of thiazolidinediones may double the risk of fractures in women.[6]
