Teneligliptin is a medication used to treat type 2 diabetes mellitus. It belongs to a class of drugs called dipeptidyl peptidase-4 (DPP-4) inhibitors. Teneligliptin works by inhibiting the enzyme DPP-4, which helps to increase the levels of incretin hormones in the body. These hormones stimulate the release of insulin from the pancreas and inhibit the release of glucagon, resulting in lower blood sugar levels. Teneligliptin is typically taken orally in the form of tablets, usually once daily. It is often used in combination with other diabetes medications and lifestyle changes such as diet and exercise to improve blood sugar control in patients with type 2 diabetes. Common side effects of teneligliptin may include headache, upper respiratory tract infections, and nasopharyngitis. If you experience severe or persistent side effects, contact your doctor promptly. It’s important to use teneligliptin as directed by a healthcare provider and to follow up regularly for monitoring and adjustment of treatment as needed.
