E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
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. |
Valutare gli effetti del vildagliptin e del sitagliptin sia sullo stress di ossidativo che sullo stato infiammatorie, in pazienti con diabete tipo 2, in scarso controllo metabolico con metformina, in base alle escursioni glicemiche giornaliere |
