Randomized Controlled TrialEfficacy and safety of the dipeptidyl peptidase-4 inhibitor, sitagliptin, in patients with type 2 diabetes mellitus inadequately controlled on glimepiride alone or on glimepiride and metformin.
To assess the efficacy and safety of a 24-week treatment with sitagliptin, a highly selective once-daily oral dipeptidyl peptidase-4 (DPP-4) inhibitor, in patients with type 2 diabetes who had inadequate glycaemic control [glycosylated haemoglobin (HbA(1c)) >or=7.5% and

ReviewThe role of angiotensin II type 1 receptor blockers in the prevention and management of diabetes mellitus.
Angiotensin II Receptor blockers (ARBs) are an important addition to the current range of medications available for treating a wide spectrum of diseases including cardiovascular diseases. Coronary heart disease (CHD) is the most common cause of death in the United Kingdom and worldwide. More importantly, the presence of the metabolic syndrome and the likelihood of diabetes mellitus taking on epidemic proportions in the years to come all threaten to maintain the mortality rate due to CHD. This review article focuses on the clinical studies that have helped define the trends in the usage of these agents in the prevention and treatment of diabetes mellitus and its complications and also explores possible mechanisms of action and future developments.

Randomized Controlled TrialTopiramate in the treatment of obese subjects with drug-naive type 2 diabetes.
The aim of this study was to examine the efficacy and safety of topiramate as an adjunct to diet and exercise in drug-naive, obese subjects with type 2 diabetes. ⋯ Topiramate as an add-on treatment to lifestyle improvements produced significant weight loss and improved glucose homeostasis in obese, drug-naive subjects with type 2 diabetes. These treatment advantages should be balanced against the occurrence of adverse events in the CNS.

Randomized Controlled TrialEffect of adding sitagliptin, a dipeptidyl peptidase-4 inhibitor, to metformin on 24-h glycaemic control and beta-cell function in patients with type 2 diabetes.
The aim of this study was to assess the effect of sitagliptin, a dipeptidyl peptidase-4 inhibitor, on 24-h glucose control when added to the regimen of patients with type 2 diabetes who had inadequate glycaemic control on metformin therapy. ⋯ In this study, the addition of sitagliptin 50 mg b.i.d. to ongoing metformin therapy improved 24-h glycaemic control and beta-cell function, and was generally well tolerated in patients with type 2 diabetes.

ReviewDipeptidyl peptidase-IV inhibitors: a major new class of oral antidiabetic drug.
Exploiting the incretin effect to develop new glucose-lowering treatments has become the focus of intense research. One successful approach has been the development of oral inhibitors of dipeptidyl peptidase-IV (DPP-IV). These drugs reversibly block DPP-IV-mediated inactivation of incretin hormones, for example, glucagon-like peptide 1 (GLP-1) and also other peptides that have alanine or proline as the penultimate N-terminal amino acid. ⋯ This review summarizes the major clinical trials with DPP-IV inhibitors as monotherapy and as add-on therapy in patients with type 2 diabetes. The magnitude of HbA(1c) reduction with DPP-IV inhibitors depends upon the pretreatment HbA(1c) values, but there seems to be no change in body weight, and very low rates of hypoglycaemia and gastrointestinal disturbance with these agents. DPP-IV inhibitors represent a major new class of oral antidiabetic drug and their metabolic profile offers a number of unique clinical advantages for the management of type 2 diabetes.
