How Vildagliptin Improves Time in Range in T2DM patients ft-Prof. Dr Aravinda Jagadeesha
The increased alpha and beta cell sensitivity to glucose by DPP4 inhibitors modulate not only chronic hyperglycemia but also daily glucose profiles and variability.
In this video, Prof. Dr Aravinda Jagadeesha, a diabetologist and the chairman at Dr. Aravinds Diabetes Centre in Bengaluru, India shares his opinion on the use of Vildagliptin to better the profile of Time in Range in patients with type 2 diabetes mellitus.
The two most widely used gliptins, sitagliptin and vildagliptin, are chemically distinct species with different characteristics of binding to DPP-4. Whereas Sitagliptin is competitive inhibitor, Vildagliptin acts as a substrate for the enzyme forming a reversible covalent complex with the catalytic site of DPP-4 that dissociates slowly, eliciting prolonged DPP-4 inhibition. This raises intact GLP-1 levels, not only after meal ingestion but also in the fasting state, and maintains suppressed glucagon levels and decreased hepatic glucose production overnight. This also results in a better glycemic variability profile.
