Abstract: Background/objectives: Visceral fat obesity plays an essential role in the clustering of cardiovascular risk factors. This study aimed to clarify the effects of miglitol, α-glycosidase inhibitor, on body weight, fat distribution and cardiovascular risk factors in patients with the metabolic syndrome. Methods and results: One hundred and eleven drug naive patients with the metabolic syndrome were continuously recruited and randomly allocated to a group of life style modification (LSM) alone or a group of LSM with miglitol per os 50mg×3 (LSM+miglitol). After 12weeks of treatment, body weight (5.1%), body mass index (4.9%) and waist circumference were greatly reduced in miglitol group (n=42) than in LSM group (n=43). Plasma levels of insulin and glucose during an oral 75g glucose loading were decreased only in miglitol group. Visceral fat area, determined by abdominal computed tomography, was greatly reduced in miglitol group (baseline 188 vs 12weeks 161cm2, p<0.0001) than in LSM group (184 vs 174cm2, p<0.05). Subcutaneous fat area was reduced only in miglitol group (p<0.001). Systolic blood pressure was reduced in miglitol group (142 vs 133mm Hg, p<0.001), but not in control group (137 vs 134mm Hg). Serum levels of triglyceride, LDL-cholesterol, γ-GTP, and high-sensitive CRP were decreased and adiponectin was increased only in miglitol group. Conclusions: Our results indicated that miglitol showed an anti-obesity potential, which was achieved by reducing abdominal fat accumulation and/or enhanced insulin requirement, and then corrected both the metabolic and hemodynamic aberrations seen in patients with the metabolic syndrome (UMIN Clinical Trial Registry UMIN000007650).
