Type 2 diabetes mellitus and obesity are associated with increased cardiovascular risk. While lifestyle interventions such as medical nutrition therapy and appropriately prescribed physical activity remain cornerstones of disease prevention and treatment, most patients with type 2 diabetes will eventually require pharmacotherapy for glycemic control. Fortunately, many of these patients are able to achieve desired glycemic targets with the use of currently available antihyperglycemic agents. Both not-for-profit disease-specific organizations and healthcare specialty societies have provided guidance about the appropriate selection of these therapies. Type 2 diabetes treatment guidelines and algorithms have been developed, taking into account a combination of evidence-based information and expert opinions, with various groups offering diverse glucose goals and approaches to hyperglycemia management. Virtually all recognize that type 2 diabetes is a multifaceted disease, necessitating an integrated yet individualized approach to patient care. © 2010. Source

Objective: To review available data on the efficacy and safety of bromocriptine-QR (BQR) and to consider its role in the management of Type 2 diabetes mellitus (T2DM). Methods: Published literature reporting the efficacy and safety of BQR in the treatment of T2DM was reviewed, including peer-reviewed abstracts and poster presentations. Results: BQR is an oral hypoglycemic agent with a novel mechanism of action that appears to involve enhancement of morning central nervous system (CNS) dopaminergic activity, resulting in improved insulin sensitivity and reduced hepatic glucose output. Adjunctive treatment with BQR in the dosing range of 1.6 to 4.8 mg/d may result in a mean (95% confidence interval [CI]) reduction in glycated hemoglobin (A1c) levels of 0.69% (0.97%, 0.41%). Treatment with BQR appears to be associated with minimal intrinsic risk of hypoglycemia, and does not appear to be associated with clinically significant adverse effects on weight, triglycerides, free fatty acids, or blood pressure. Conclusion: The favorable cardiovascular risk profile of BQR suggests that it may be useful in the treatment of patients with T2DM with a history of cardiovascular disease (CVD) or who have significant risk factors for CVD. However, knowledge of the efficacy and safety of BQR is limited by the relatively small clinical trials database. As a result, there is currently insufficient information on the safety and efficacy of adjunctive BQR in T2DM patients being treated with several common diabetes regimens (e.g., thiazolidinediones, insulin).

OBJECTIVE - To evaluate efficacy and safety of switching from twice-daily exenatide to once-daily liraglutide or of 40 weeks of continuous liraglutide therapy. RESEARCH DESIGN AND METHODS - When added to oral antidiabetes drugs in a 26-week randomized trial (Liraglutide Effect and Action in Diabetes [LEAD]-6), liraglutide more effectively improved A1C, fasting plasma glucose, and the homeostasis model of β-cell function (HOMA-B) than exenatide, with less persistent nausea and hypoglycemia. In this 14-week extension of LEAD-6, patients switched from 10 μg twice-daily exenatide to 1.8 mg once-daily liraglutide or continued liraglutide. RESULTS - Switching from exenatide to liraglutide further and significantly reduced A1C (0.32%), fasting plasma glucose (0.9 mmol/l), body weight (0.9 kg), and systolic blood pressure (3.8 mmHg) with minimal minor hypoglycemia (1.30 episodes/patient-year) or nausea (3.2%). Among patients continuing liraglutide, further significant decreases in body weight (0.4 kg) and systolic blood pressure (2.2 mmHg) occurred with 0.74 episodes/patient-year of minor hypoglycemia and 1.5% experiencing nausea. CONCLUSIONS - Conversion from exenatide to liraglutide is well tolerated and provides additional glycemic control and cardiometabolic benefits. © 2010 by the American Diabetes Association. Source

The two classes of incretin-related therapies, dipeptidyl peptidase-4 (DPP-4) inhibitors and glucagon-like peptide-1 receptor agonists (GLP-1 RAs), have become important treatment options for patients with type 2 diabetes. Sitagliptin, saxagliptin, vildagliptin and linagliptin, the available DPP-4 inhibitors, are oral medications, whereas the GLP-1 RAs-twice-daily exenatide, once-weekly exenatide and once-daily liraglutide-are administered subcutaneously. By influencing levels of GLP-1 receptor stimulation, these medications lower plasma glucose levels in a glucose-dependent manner with low risk of hypoglycaemia, affecting postprandial plasma glucose more than most other anti-hyperglycaemic medications. Use of GLP-1 RAs has been shown to result in greater glycaemic improvements than DPP-4 inhibitors, probably because of higher levels of GLP-1 receptor activation. GLP-1 RAs can also produce significant weight loss and may reduce blood pressure and have beneficial effects on other cardiovascular risk factors. Although both classes are well tolerated, DPP-4 inhibitors may be associated with infections and headaches, whereas GLP-1 RAs are often associated with gastrointestinal disorders, primarily nausea. Pancreatitis has been reported with both DPP-4 inhibitors and GLP-1 RAs, but a causal relationship between use of incretin-based therapies and pancreatitis has not been established. In clinical trials, liraglutide has shown efficacy and tolerability and resulted in certain significant benefits when compared with exenatide and sitagliptin. © 2012 Blackwell Publishing Ltd. Source

Purpose: Optimizing glycemic control in patients with type 2 diabetes mellitus (T2DM) not controlled with ≥ 1 oral antidiabetes drugs (OADs) is challenging. Many therapeutic options exist; however, data comparing the effectiveness of different strategies are lacking for the management of patients with T2DM. Our study aim was to provide comparative data on efficacy and hypoglycemia when initiating insulin glargine (glargine) versus alternative treatment options (not including the newest antidiabetes agents, glucagon-like peptide [GLP]-1 receptor agonists, dipeptidyl peptidase [DPP]-4 inhibitors or sodium-glucose linked transporter [SGLT]-2 inhibitors) in insulin-naive patients with T2DM who remained uncontrolled with OADs. Methods: Patient-level data were pooled from 9 randomized controlled trials of ≥ 24 weeks duration with comparable patient populations. The effect of adding glargine was compared with intensification of lifestyle interventions or OADs, addition of neutral protamine Hagedorn (NPH) insulin, insulin lispro, premixed insulin, or all comparators pooled, on patient glycated hemoglobin (HbA1c) level, fasting plasma glucose level, weight, and hypoglycemia. Results: A greater proportion of patients achieved a target HbA1c level ≤ 7.0% with glargine treatment than with pooled comparators, intensification of OADs, or lifestyle interventions; there was no difference when compared with NPH, premixed, or insulin lispro use. The rate for reported hypoglycemic events was lower for glargine use than for pooled comparators or other insulins, but higher compared with intensification of lifestyle interventions or OADs. When stratified by baseline HbA1c level, efficacy/target attainment with glargine use was better than for pooled comparators across all HbA1c strata; OAD intensification, when baseline HbA1c level was ≥ 8.0%; and premixed insulin if baseline HbA1c level was < 8.0%; but similar to other insulins for all other categories. The incidence of reported hypoglycemia was less frequent with glargine use than other insulins, but more frequent than intensification of lifestyle interventions or OADs. Conclusion: When adequate glycemic control is not achieved using OADs in patients with T2DM, initiating insulin glargine is generally less likely to elicit hypoglycemia than initiating NPH, premixed, or prandial insulins, and the benefit–risk balance supports initiating insulin rather than intensification of OAD therapy when baseline HbA1c level is ≥ 8.0%. © Postgraduate Medicine.
