What treatment medications help prevent type 2 diabetes?

  • As described previously, metformin (Glucophage) has been shown in the DPP trial to prevent the development of diabetes in some people with impaired glucose tolerance. While not quite as effective as intensive lifestyle change, metformin decreased the rate of progression from 29% in the placebo group to 22%.
  • The American Diabetes Association has recommended metformin for the prevention of diabetes in very high-risk individuals.
    • High-risk individuals are those under 60 years of age or who are obese, or women with a history of gestational diabetes who have impaired fasting glucose (IFG), impaired glucose tolerance (IGT), or hemoglobin A1C levels of 5.7% to 6.4%, in whom lifestyle interventions fail to improve control of glucose levels.
  • Acarbose (Precose), a drug designed to reduce small intestinal absorption of carbohydrates has been used with some success as well and is licensed for diabetes prevention in some countries. The STOP NIDDM trial showed that in about 1400 patients with impaired glucose tolerance, acarbose significantly reduced progression to diabetes compared to placebo. However, the occurrence of gastrointestinal side effects have limited the use of this drug for some people.
