Dapagliflozin and saxagliptin tablets for adults with type 2 diabetes.

Saxagliptin (a dipeptidyl peptidase-4 inhibitor, DPP-4i) and dapagliflozin (a sodium-glucose cotransporter type 2 inhibitor, SGLT2i) improve glucose control in type 2 diabetes (T2D) through different potentially complementary mechanisms, thus offering the opportunity for a combined therapy. Area covered: The characteristics of the saxagliptin/dapagliflozin combination are analysed, focusing on: 1) pharmacokinetic and pharmacodynamic properties; 2) efficacy and safety in phase III trials with concurrent and sequential add-on therapy; and 3) potential use in clinical practice, including in special populations (cardiovascular disease, heart failure, chronic kidney disease, elderly). Expert commentary: Conclusions drawn from clinical trials investigating combination with the separate drugs are considered to apply to the fixed-dose combination (FDC) that demonstrates bioequivalence. Dual saxagliptin/dapagliflozin therapy is more potent than either monotherapy and can be used as an initial combination or a stepwise sequential approach. Dual therapy is generally well tolerated and may be used in special populations, with some limitations because of the presence of dapagliflozin. However, the latter may offer some advantages because of multiple effects attributed to SGLT2i. The best place of this dual combination for the management of T2D and the profile of patients who will make the most of this combined therapy remains to be defined.
