Alpha-glucosidase inhibitors have been available for clinical use for about 20 years. They have shown reasonably good efficacy comparable to other oral blood glucose lowering drugs and in some parts of the world are the most commonly prescribed oral diabetes medication, especially in Asian countries. Unlike as has been observed with some other blood glucose lowering agents, however, no adverse signals of potential cardiovascular harm have emerged in relation to their use. On the contrary, significant beneficial cardiovascular outcome results have been observed in the post-hoc analyses of randomised placebo-controlled trials with the alpha-glucosidase inhibitor acarbose. Targeting mainly postprandial hyperglycaemia, alpha-glucosidase inhibitors favourably affect several cardiovascular risk factors, such as obesity, hypertension and high glycaemic variability with little to no risk for hypoglycaemia. Furthermore, acarbose favourably affects endothelial dysfunction and carotid intima media thickening in humans and, in animal models, improves cardiac interstitial fibrosis and hypertrophy of cardiomyocytes. The ultimate determination of the cardiovascular effects of alpha-glucosidase inhibitors in terms of clinical outcomes awaits the results of ongoing long-term, randomised, placebo-controlled trials.

We evaluated the effects of an alpha-glucosidase inhibitor, voglibose, on cardiovascular events in patients with a previous myocardial infarction (MI) and impaired glucose tolerance (IGT).. This prospective, randomized, open, blinded-endpoint study was conducted in 112 hospitals and clinics in Japan in 3000 subjects with both previous MI and IGT receiving voglibose (0.6 mg/day, n = 424) or no drugs (n = 435) for 2 years. The Data and Safety Monitoring Board (DSMB) recommended discontinuation of the study in June 2012 after an interim analysis when the outcomes of 859 subjects were obtained. The primary endpoint was cardiovascular events including cardiovascular death, nonfatal MI, nonfatal unstable angina, nonfatal stroke, and percutaneous coronary intervention/coronary artery bypass graft. Secondary endpoints included individual components of the primary endpoint in addition to all-cause mortality and hospitalization due to heart failure.. The age, ratio of males, and HbA. Although voglibose effectively treated IGT, no additional benefits for cardiovascular events in patients with previous MI and IGT were observed. Voglibose may not be a contributing therapy to the secondary prevention in patients with MI and IGT.. Clinicaltrials.gov number: NCT00212017.

In this study we examined the effects of switching α-glucosidase inhibitors (α-GI) from acarbose or voglibose to miglitol on glucose fluctuations and circulating concentrations of cardiovascular disease risk factors, such as soluble adhesion molecules (sE-selectin, sICAM-1 and sVCAM-1), a chemokine monocyte chemoattractant protein (MCP)-1, plasminogen activator inhibitor-1, and fatty acid-binding protein 4, in type 2 diabetic patients for 3 months.. We enrolled 47 Japanese patients with type 2 diabetes, with HbA1c levels with 7.26 ± 0.5 % (mean ± standard deviation), and who were treated with the highest approved dose of acarbose (100 mg/meal) or voglibose (0.3 mg/meal) in combination with insulin or sulfonylurea. Patients' prior α-GIs were switched to a medium dose of miglitol (50 mg/meal), and the new treatments were maintained for 3 months. Thirty-five patients who completed the 3-month study and provided serum samples were analyzed.. The switch to miglitol for 3 months did not affect HbA1c, fasting glucose, triglycerides, total-cholesterol or C-reactive protein levels, or result in any adverse events. Glucose fluctuations were significantly improved by the change in treatment (M-value: 10.54 ± 4.32 to 8.36 ± 2.54), while serum protein concentrations of MCP-1 (525.04 ± 288.06-428.11 ± 163.78 pg/mL) and sE-selectin (18.65 ± 9.77-14.50 ± 6.26 ng/mL) were suppressed.. Our results suggest that switching from acarbose or voglibose to miglitol for 3 months suppressed glucose fluctuations and serum protein levels of MCP-1 and sE-selectin in type 2 diabetic Japanese patients, with fewer adverse effects.

The detrimental effects of a sedentary lifestyle and poor dietary habits are having a significant negative impact on health statistics, with obesity and its attendant risks becoming a major problem in most developed nations, including Japan. Interventions which prevent or delay the development of type 2 diabetes have the potential to reduce the morbidity and mortality associated with the disease and, as a consequence, related healthcare costs. The study conducted to assess whether alpha-glucosidase inhibitor, voglibose could prevent type 2 diabetes developing in high-risk Japanese subjects with impaired glucose tolerance (IGT). 1,780 eligible subjects received standard diet and exercise therapy, and 897 were randomised to receive voglibose and 883 placebo. The study was planned for treatment to be continued until participants developed type 2 diabetes [primary endpoint; determined by bi-annual oral glucose tolerance tests (OG'Ts) as well as fasting blood glucose measured every 3 months] or normoglycaemia or for a minimum of 3 years, subject to the findings of an interim analysis. The interim analysis significantly favoured voglibose and end-of-study report involves individuals treated for an average of 48.1 weeks. Subjects treated with voglibose had a significantly lower risk for the progression to type 2 diabetes than placebo (50/897 vs 106/881: hazard ratio 0.595). Also, significantly more subjects in the voglibose group achieved normoglycaemia compared with those in the placebo group (599/897 vs 454/881: hazard ratio 1.539). Voglibose, in addition to standard care with diet and exercise, was effective in preventing the progression of IGT to type 2 diabetes and in increasing the proportion of individuals with normoglycaemia in high-risk Japanese subjects with IGT.
