The guidelines specifically recommend DPP-4 inhibitors as monotherapy for patients with HbA1c levels between 6.5% and 7.5%, as part of 2-drug combination therapy with metformin in patients with HbA1c levels between 7.6% and 9.0%, and as part of triple combination therapy (eg, with metformin and a TZD) for patients with HbA1c 9.0%.1 The guidelines also note that these agents have low risk for hypoglycemia and no long-term toxicities to date.1 ADA/EASD 2009 guidelines do not consider DPP-4 inhibitors as preferred (ie, tier 1 or tier 2) interventions because at the time of publication, DPP-4 inhibitors were considered too new and their long-term safety was still undetermined.12 However, these guidelines take note of the fact that DPP-4 inhibitors lower HbA1c levels by 0.6%C0.9%, are weight neutral, and are not associated with hypoglycemia when used as monotherapy.12 Emerging role of combination therapy In addition to the emerging role of DPP-4 inhibitors as initial therapy, combination therapy is recommended by AACE/ACE for patients with HbA1c 7.6%.1 When patients are unsuccessful in achieving or sustaining their HbA1c goals with lifestyle intervention and appropriately titrated monotherapy, advancement to dual therapy should be considered.1 The ADA/EASD recommendations also indicate that if lifestyle intervention and the maximum tolerated dose of metformin fail to accomplish or sustain glycemic goals, another medication should be added within 2C3 months of treatment initiation or at any time the target HbA1c is not achieved.12 The treatment algorithm put forward as part of the Banting Lecture by Dr Ralph DeFronzo in 2009 2009 also favored combination therapy for the treatment of T2DM, noting that combination treatment based on the reversal of known pathophysiological defects provides greater potential for the achievement of sustained glycemic control.15 Place in therapy Although metformin continues to be the recommended first-line agent for patients with T2DM, the value of DPP-4 inhibitors is becoming increasingly acknowledged in current treatment algorithms as first-line treatment and second-line treatment options due to their efficacy (including HbA1c control and preferential targeting of PPG) and well-tolerated profile. cannot accomplish glycemic control with a combination of diet and lifestyle changes and metformin, SU, or TZD. analysis provided no evidence of increased CV risk with saxagliptin as monotherapy or in combination with other oral antidiabetic agents.

Scope, aims, and objectives Dipeptidyl peptidase-4 (DPP-4) inhibitors have been added to the armamentarium of traditional antidiabetic medications and are currently recommended by the American Association of Clinical Endocrinologists (AACE)/American College of Endocrinology (ACE) guidelines as an option for initial monotherapy in patients with glycated hemoglobin Phloroglucinol A1c (HbA1c) 6.5%C7.5%, and as part of combination treatment with metformin for patients with type 2 diabetes mellitus (T2DM) and an HbA1c 7.6%.1 Saxagliptin (Onglyza?; Bristol-Myers Squibb Organization, Princeton, NJ, USA; AstraZeneca Pharmaceuticals LP, Wilmington, DE, USA) is usually a once-daily, oral DPP-4 inhibitor that has been submitted for regulatory review in more than 50 countries and is approved in 38 countries, including the United States and member says of the European Union, for patients with T2DM who are unable to maintain glycemic control with diet and exercise alone or on metformin, a sulfonylurea (SU), or a thiazolidinedione (TZD).2 In addition to being well tolerated without increasing the risk of hypoglycemia, saxagliptin produces significant reductions in HbA1c, fasting plasma glucose (FPG), and postprandial glucose (PPG) levels when used as monotherapy and in combination with metformin, SUs (eg, glyburide), and TZDs (eg, pioglitazone or rosiglitazone).2C7 The purpose of this short article is to review the mechanism of action and current clinical evidence on saxagliptin as they relate to the management of patients with T2DM. Methods English language literature searches were conducted. Databases were searched between 1 January 2004 and 9 November 2009, using the search terms saxagliptin OR BMS-477118 and type 2 diabetes.

Thirty-eight of these records were duplicates and were not considered further.
