Effects of Dapagliflozin+Saxagliptin in Addition to Metformin v/s Saxagliptin or Dapagliflozin in Patients With DM2.

Dapagliflozin (Forxiga) currently is approved for the treatment of T2DM (6). Dapagliflozin inhibits SGLT2, promote the excretion of 80-90 grams of glucose per day in the urine, and lower the plasma glucose concentration. This class of drugs has been shown to effectively reduce the HbA1c at all stages of T2DM and can be used in combination of all other anti-diabetic agents including insulin.

Saxagliptin is a highly potent DPP4 inhibitor.In patients with type 2 diabetes, administration of saxagliptin led to inhibition of DPP4 enzyme activity for a 24-hour period.After an oral glucose load,this DPP4 inhibition resulted in a 2- to 3-fold increase in circulating levels of active incretin hormones, including glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), decreased glucagon concentrations and increased glucose-dependent beta-cell responsiveness, which resulted in higher insulin and C-peptide concentrations.The rise in insulin from pancreatic beta-cells and the decrease in glucagon from pancreatic alpha-cells were associated with lower fasting glucose concentrations and reduced glucose excursion following an oral glucose load or a meal.Saxagliptin improves glycaemic control by reducing fasting and postprandial glucose concentrations in patients with type 2 diabetes.
