Efficacy and safety of metformin-sitagliptin combination for the treatment of patients with diabetes mellitus and obesity

Abstract

Aim. To elucidate therapeutic effect of metformin-sitaglitin combination on the dynamics of indices of insulin resistance and functional activity of pancreaticbeta-cells, lipid metabolism and body weight in patients with type 2 diabetes mellitus (DM2) and obesity. Materials and methods. The study included 32 patients treated by a combination of metformin (500-2550 mg/day) and sitagliptin (100 mg) for18 weeks. Standard parameters of carbohydrate and lipid metabolism, body mass index (BMI), blood adiponectin and leptin levels were measured, indices of insulin resistance and functional activity of pancreatic beta-cells were calculated. Results. Therapy with metformin-sitagliptin combination ensured compensation of fasting and postprandial hyperglycemia, reduced HbA1c level, increasedfunctional activity of beta-cells, decreased peripheral insulin resistance and BMI, had beneficial effect on lipid metabolism and hormonalactivity of adipose tissue. Conclusion. Metformin-sitagliptin combination can be recommended as a clinically efficacious modality for the treatment of patients with diabetesmellitus and obesity.
