PATIENTS WITH HEPATIC IMPAIRMENT
- Use caution and monitor patient closely. Do not administer if AST > 2.5 times the upper level of normal.
- Rosiglitazone is a thiazolidinedione antidiabetic agent which improves insulin sensitivity by lowering blood glucose level without increasing pancreatic insulin secretion. It is dependent on the presence of insulin. Rosiglitazone is a potent agonist for the peroxisome proliferator-activated receptor-gamma, which in turn regulates the transcription of insulin-responsive genes involved in the control of glucose production, transport and utilization.
