Sitagliptin, a novel orally-active clipeptidyl-peptidase (DPP-4) inhibitor has been introduced into type 2 diabetes therapy. Sitagliptin inhibits the degradation of glucagon-like peptide-1 (GLP-1) and gastric inhibitory polypeptide (GIP), as well as that of other regulatory peptides important for glucose homeostasis. It reduces haemoglobin A1c (HbA1c), fasting and postprandial glucose by glucose-dependent stimulation of insulin secretion and inhibition of glucagon secretion. Sitagliptin is weight neutral. Indirect measures show a possible improvement of beta-cell function. Sitagliptin does not cause hypoglycemia when compared to metformin or placebo. Metformin, which has a different unique mechanism, has been used in type 2 diabetes for approximately 50 years. Metformin improves insulin resistance and is the first-line anticliabetic drug in use today. The combination of a DPP-4 inhibitor with metformin allows a broad and complementary spectrum of antidiabetic actions. This combination does not increase the risk of hypoglycaemia nor does it promote weight gain, an adverse effect of various other oral antidiabetic combinations. This article gives an overview of the data available on the combined anticliabetic effects
