Also Known As: Pioglitazone, Actos, Glustin, Zactos

Pioglitazone is a prescription drug of the class thiazolidinedione (TZD) with hypoglycemic (antihyperglycemic, antidiabetic) action. Pioglitazone is marketed as trademarks Actos in the USA, Canada, the UK and Germany, Glustin in Europe,"Glizone" and "Pioz" in India by Zydus CND and USV respectively and Zactos in Mexico by Takeda Pharmaceuticals. Actos was the tenth-best selling drug in the U.S. in 2008, with sales exceeding $2.4 billion. Its cardiovascular safety profile compares favorably with rosiglitazone (Avandia), which was withdrawn after concerns about an increased risk of cardiac events. However, pioglitazone has subsequently been found to be associated with bladder tumors and has been withdrawn in some countries.

Pioglitazone is used for the treatment of diabetes mellitus type 2 (previously known as non-insulin-dependent diabetes mellitus, NIDDM) in monotherapy and in combination with a sulfonylurea, metformin, or insulin. Pioglitazone has also been used to treat non-alcoholic steatohepatitis (fatty liver), but this use is presently considered experimental.[6] Pioglitazone has also been found to reduce the risk of conversion from prediabetes to diabetes mellitus type 2 by 72%.
