This is a great feat!  Although I should place a caveat that TWICE as effective as this medicine for preventing diabetes is lifestyle modification with diet and exercise (see below for specifics).

Metformin is a medicine that reduces the risk of developing diabetes in “at-risk” adults when compared to taking placebo pills.  This effect is likely effective for up to 10 years.

Who is  “at-risk”?  Those with…

• Elevated fasting glucose (more than 100 on a fasting lab test),
• Hemoglobin A1c test result 5.7-6.4,
• History of gestation diabetes with a pregnancy,
• Obesity (BMI of more than 25),
• Polycystic ovary syndrome,
• Family history of diabetes,
• Hypertension,
• Peripheral Vascular Disease,
• High cholesterol.

Lifestyle modification is harder than taking a pill every day, but may also positively affect many other areas of your life.  This study showed that a modest weight loss of 7% body weight and exercising 150 minutes per week was greatly effective in decreasing the risk of converting to overt diabetes.
