舍曲林, known as Saxagliptin, is a medication used to manage type 2 diabetes. It works by increasing the levels of incretin hormones, which help regulate blood sugar levels. By inhibiting the enzyme DPP-4, it allows the body to produce more insulin when needed and reduces the amount of glucose released by the liver. This drug is typically prescribed alongside diet and exercise to improve glycemic control. Common side effects may include upper respiratory infections and headaches. Patients should consult their healthcare provider for personalized advice and to understand potential interactions with other medications.
