MOA. Pioglitazone is a thiazolidinedione antihyperglycemic and a potent peroxisome proliferator-activated receptor-gamma (PPAR [gamma]) agonist used to improve insulin sensitivity in patients with Type II diabetes. Insulin-dependent glucose disposal in skeletal muscle is improved and hepatic glucose production is decreased; both actions contribute to pioglitazone’s glucose-lowering effects.
