Description: Pioglitazone is as a potent and highly selective agonist for the peroxisome proliferator activated receptor-γ (PPAR-γ). Activation of these receptors promotes the production of gene products involved in lipid and glucose metabolism. It also improves insulin response to target cells w/o increasing the pancreatic secretion of insulin.
