MeasureTime frame
Main Objective: to compare the respective effects of vildagliptin and sitagliptin, as a regulation strategy attempting to stabilize glucose excursions over 24 hours, on oxidative stress and proinflammatory cytokines implicated in the atherosclerotic process, in patients with type 2 diabetes poorly controlled with metformin therapy.;Secondary Objective: none;Primary end point(s): nitrotyrosine and proinflammatory cytokines reduction
