One hundred ten subjects whose medications were not changed during the observation period were investigated as the full analysis set to assess the effectiveness. The subjects were divided into two groups: non-elderly subjects (n=72) of<65 years of age and elderly subjects (n=38) of≥65 years of age.Results: Although the body weight and HbA1c, AST, ALT and γ-GTP levels were significantly reduced in both the non-elderly and elderly subjects, blood pressure, eGFR and urinary protein excretion were only significantly decreased in the non-elderly subjects. The hemoglobin, hematocrit and serum HDL-cholesterol levels were significantly elevated in both groups. The change in eGFR showed a significant positive association with the change in blood pressure. The change in urinary protein excretion tended to be correlated with the change in blood pressure.Conclusion: Although renoprotective effects might be limited, empagliflozin can safely and effectively improve metabolic parameters, even in elderly subjects.Keywords: sodium-glucose cotransporter 2 inhibitor, empagliflozin, type 2 diabetes mellitus, elderly, renoprotection, renal impairment
