Alogliptin is a potent and highly selective inhibitor of DPP-4, >10,000-fold more selective for DPP-4 than other related enzymes including DPP-8 and DPP-9. Alogliptin improves glycaemic control via a glucose-dependent mechanism, whereby insulin release is enhanced and glucagon levels are suppressed when glucose levels are high.

Pioglitazone effects may be mediated by a reduction of insulin resistance. Pioglitazone appears to act via activation of specific nuclear receptors (peroxisome proliferator activated receptor gamma) leading to increased insulin sensitivity of liver, fat and skeletal muscle cells in animals. Treatment with pioglitazone has been shown to reduce hepatic glucose output and to increase peripheral glucose disposal in the case of insulin resistance.
