Abstract

OBJECTIVE: To demonstrate the efficacy, tolerability, and safety of acarbosecompared with placebo in patients with type 2 diabetes inadequatelycontrolled with diet and metformin (2,000 or 2,500 mg/day in divideddoses). RESEARCH DESIGN AND METHODS: This study had a multicenter randomized double-blind placebo-controlled parallel-group comparison design. The trial lasted 31 weeks and consisted of a 1-week screening period, a 6-week placebo pretreatment period, and a 24-week period of acarbose or placebo, with a forced titration from 25–50 mg t.i.d. and a titration of 50–100 mg tid that was based on glucose control. The primary efficacy variable wasthe mean change from baseline in HbAlc. Secondary efficacy variables included mean changes from baseline in fasting and postprandial plasma glucose, serum insulin, and triglyceride levels. RESULTS: The addition of acarbose to patients on background metformin and diet therapy showed a statistically significant reduction in mean HbAlc of 0.65%. There were statistically significant reductions in fasting and postprandial plasma glucose and serum insulin levels compared with placebo. Gastrointestinal side effects were more frequently reported in the acarbose-treated patients. No significant differences in liver transaminase elevations were observed between patients treated with acarbose and those treated with placebo. CONCLUSIONS: The results of this study demonstrate that the addition of acarbose to patients with type 2 diabetes who are inadequately controlled with metformin and diet is safe and generally well tolerated and that it significantly lowers HbAlc and fasting and postprandial glucoseand insulin levels.

  • Association of acarbose to metformin in sub-optimally controlled patients reduced HbA1c by about 0.8-1.0%.

    “However, it has been reported that the association of acarbose to metformin in sub-optimally controlled patients reduced HbA1c by about 0.8-1.0% [38].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
