Januvia is considered as a DPP-4 inhibitor that is established to work among patients with type 2 diabetes by inhibiting the inactivation of hormones called incretin. With Januvia, the concentrations of these active intact hormones are heightened and improved, resulting in prolonged and upgraded activities of these hormones. Reduced incretin inhibition improves insulin production and lower release of glucagon in a way that is associated with concentrations of glucose. These effects potentially increase control over blood sugar, which is supported by a significant decrease in glycosylated hemoglobin. This is how Januvia operates to maintain and stabilize type 2 diabetes.
