Antidiabetics, Dipeptidyl Peptidase IV Inhibitors

Incretin hormones are part of an endogenous system involved in the physiologic regulation of glucose homeostasis. They increase insulin release and decrease glucagon levels in the circulation in a glucose-dependent manner. DPP-4 degrades numerous biologically active peptides, including the endogenous incretins GLP-1 and glucose-dependent insulinotropic peptide (GIP). DPP-4 inhibitors prolong the action of incretin hormones.

Sitagliptin (Januvia)

Sitagliptin demonstrates selectivity for DPP-4 and does not inhibit DPP-8 or DPP-9 activity in vitro at concentrations approximating those from therapeutic doses. Sitagliptin can be used as a monotherapy or in combination with metformin or a thiazolidinedione. It is given once daily and is weight neutral.

Saxagliptin (Onglyza)

Saxagliptin inhibits DPP-4 and thereby increases concentrations of GLP-1 and GIP, which stimulate insulin release in response to increased blood glucose levels following meals. This action enhances glycemic control. Saxagliptin is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus.

Linagliptin (Tradjenta)

Linagliptin is a DPP-4 inhibitor that increases and prolongs incretin hormone activity. It is indicated for adults with type 2 diabetes mellitus, along with diet and exercise, to lower blood glucose levels. It may be used as monotherapy or in combination with other common antidiabetic medications, including metformin, sulfonylurea, or pioglitazone; it has not been studied in combination with insulin.

Alogliptin (Nesina)

Selective dipeptidyl peptidase-4 (DPP-4) inhibitor; slows inactivation of incretin hormones (eg, GLP-1, GIP), thereby reducing fasting and postprandial glucose concentrations in a glucose-dependent manner
