In this study, 60 patients with type 2 diabetes were randomly divided into group A or group B after stable glucose control. Flash Glucose Mornitoring(FGM) will be used in patients with two groups. Patients in group A were given sitagliptin and metformin for the first two weeks, and then were treated with acarbose and metformin for the second two weeks. FGM was used to monitor glycemic variations during the whole four weeks. The opposite therapy was true for patients in group B.
The aim of the study is to compare the FGM glycemic profiles in patients with type 2 diabetes mellitus treated with sitagliptin and acarbose.
