Abstract

|
Objectives: This study aimed to compare effects on glycemic control and weight loss between the metformin/dapagliflozin
combination and the metformin/sitagliptin combination in type 2 diabetic patients.
Methods: This study retrospectively reviewed the medical records, from January 1st 2015 to March 31st 2016, of type 2 diabetic patients who were older than 18 and were prescribed with dapagliflozin or sitagliptin in combination with metformin. Hemoglobin A1c (HbA1c) levels and weights were measured every 3 months.
Results: The dapagliflozin group showed a greater decrease in HbA1c levels after 3 months (-0.75% vs. 0.01%, P<0.001), 6 months (-0.36% vs. 0.08%, P=0.029), and 9 months (-0.53% vs. 0.08%, P=0.046) compared to the sitagliptin group. Also, the
dapagliflozin group showed a greater significant decrease in the rate of change in HbA1c levels after 3 months (-0.09 vs. 0.01, P<0.001), 6 months (-0.04 vs. 0.01, P=0.031), 9 months (-0.07 vs. 0.02, P=0.029), and 12 months (-0.05 vs. 0.05, P=0.047). Furthermore, the dapagliflozin group showed a greater decrease in amount of weight change after 3 months (-2.46 kg vs. 0.37 kg, P<0.001), 6 months (-3.02 kg vs. 0.13 kg, P<0.001), and 9 months (-2.27 kg vs. 0.50 kg, P=0.002). Finally, the dapagliflozin group showed a greater decrease in the rate of change in weight after 3 months (-3.10% vs. 0.52%, P<0.001), 6 months (-3.83% vs. 0.21%, P<0.001), 9 months (-2.84% vs. 0.79%, P=0.002), and 12 months (-4.91% vs. 0.44%, P<0.001).
Conclusions: It was concluded that dapagliflozin is more effective than sitagliptin for type 2 diabetic patients.
