Which drug is classified as a Dipeptidyl Peptidase-4 Inhibitor?

Sitagliptin is classified as a Dipeptidyl Peptidase-4 (DPP-4) inhibitor, which is a type of medication used primarily for the management of type 2 diabetes. DPP-4 inhibitors work by blocking the enzyme DPP-4, which leads to increased levels of incretin hormones. These hormones are important for regulating blood sugar levels, as they stimulate insulin secretion in response to meals and reduce the amount of glucose produced by the liver.

By inhibiting DPP-4, sitagliptin helps to improve glycemic control, making it an effective option for patients who are unable to achieve adequate control with diet and exercise alone or who require additional therapy in combination with other antidiabetic medications. It is important to understand the function and mechanism of DPP-4 inhibitors in diabetes management, as this class of drugs can play a significant role in personalized patient care.

In contrast, options like Metformin belong to a different class of antidiabetic medications called biguanides, which primarily work by improving insulin sensitivity and decreasing glucose production in the liver. Glimepiride is a sulfonylurea that stimulates insulin secretion from the pancreas. Carbamazepine is an anticonv
