Metformin and Its Impact on the Substances Associated With NO Production in Prediabetes Patients.

Summary

This study evaluates the effect of different doses of metformin on the function of endothelium in people with pre-diabetes. One group of the patients will receive metformin in dose: 1500 mg, the second one will receive 3000 mg/day. The parameters from healthy volunteers will be taken only at the study beginning to compare the test results with the parameters from patients with pre-diabetes. This group will be not treated with metformin (no intervention)
