SGLT2 and DPP4 inhibitors are new effective oral antidiabetic drugs with low risk of hypoglycemia and positive or neutral impact on body weight. These characteristics are substantially different from more widely used sulphonyl-ureas. Current treatment of type 2 diabetes is rather complicated. Moreover, the position of new antidabetics in the guidelines has not yet been clearly defined. Personalised treatment on the basis of molecular markers is still not possible. Therefore, the position of new antidiabetics in the treatment of type 2 diabetes is often determined by clinical experience and subsequently modified by new clinical studies. Currently, doctors are asking which of these modern antidabetics to choose. The following text might help in this decision.
