Sitagliptin - DPP4i
Sitagliptin inhibits dipeptidyl peptidase-4 (DPP-4), an enzyme that breaks down incretin hormones, thereby increasing insulin secretion and reducing glucagon in response to meals.
Sitagliptin inhibits dipeptidyl peptidase-4 (DPP-4), an enzyme that breaks down incretin hormones, thereby increasing insulin secretion and reducing glucagon in response to meals. Used for Type 2 diabetes mellitus as monotherapy or in combination with other antidiabetic agents.

Mechanism of action
DPP-4 inhibitors work by prolonging the action of endogenous GLP-1 and GIP, which are incretin hormones released after nutrient intake. By blocking their degradation, sitagliptin enhances glucose-dependent insulin secretion and suppresses glucagon secretion, leading to improved glycemic control. This mechanism is glucose-dependent, meaning it primarily works when blood glucose is elevated, reducing hypoglycemia risk.
