Diabetes Mellitus

Prevent/delay development of type 2 diabetes in subjects with impaired glucose homeostasis treated with Acarbose in Primary Care

Trial purpose

The purpose of the study is to determine if the administration of small doses of Acarbose can prevent or delay the appearance of Type 2 Diabetes Mellitus in a population of subjects with prediabetes.

Primary Outcome

  • The principal objective was to determine if the administration of small doses of Acarbose could prevent or delay the appearance of Type 2 DM in a population of subjects with impaired glucose homeostasis.
    date_rangeTime Frame:
    The main criterion for the evaluation of the primary objective was the proportion of diabetic subjects after three years of treatment and another time after three months of wash-out with placebo.
