Primarily fight insulin resistance and reduces hepatic glucose production. Increases muscle, fatty tissue and liver sensitivity to insulin. Intermediate A1C reduction potential (0.5 - 1.4%). Promote hydric retention and weight gain, increasing the risk of heart failure. Also increase the risk of fracture. Recent results of studies such as RECORD and BARI 2D indicate that rosiglitazone does not increase the risk of infarction and CVD. The gene discussed is INS; the disease is Insulin resistance.
