Outcome Measures

Primary Outcomes (1)

  • Change in mean amplitude of glycemic excursion(MAGE) for 12 weeks(12weeks - 0 week).

    To compare the effect of vildagliptin based treatment for 12 weeks on glycemic variability with sulfonylurea using continuous glucose monitoring system(CGMS).

    0 week and 12 weeks

Secondary Outcomes (1)

  • Change from baseline in oxidative stress markers and inflammatory markers at 12 weeks. Change from baseline in endothelial cell function at 12 weeks.

    0 week and 12 weeks
