RESUMO
INTRODUCTION: Type 2 diabetes mellitus (T2DM) has burdened health systems in the world to the value of 500 billion dollars/year. Dipeptidyl peptidase 4 inhibitors (DPP-4 Inhibitors) have been strongly associated with spending on the treatment of T2DM by the courts in Brazil. The aim of this study was to estimate the most cost-effective DPP-4 Inhibitor for T2DM treatment. A pharmacoeconomic study of cost-effectiveness was performed in a medium-sized municipality in Minas Gerais state, Brazil. METHODS: The data are from legalization in municipal health in 2013. The effectiveness of DPP-4 Inhibitors was measured by the reduction in glycated hemoglobin (A1c). The direct medical costs of drug and adverse drug reactions were identified. With these data, a cost-effectiveness ratio (CER) and construction of the decision tree for sensitivity analysis were performed. RESULTS: The representative of the most effective in reducing A1c gliptins was sitagliptin in combination with metformin, it was able to reduce A1c by 1.16% (1.09 to 1.22, CI 95%). The drug with the lowest cost was linagliptin, with a cost per patient/year of US$ 481.42. Sensitivity analysis performed by the decision tree shows that sitagliptin in association with metformin had the CER of US$ 1,506.75 per patient/year, to reduce A1c by 1%. CONCLUSION: The most cost-effective DPP-4 Inhibitor was sitagliptin with metformin.
