Lixisenatide is primarily used in the management of type 2 diabetes. It works by mimicking the action of the incretin hormone GLP-1, which helps regulate blood sugar levels. This medication is often prescribed when other diabetes treatments, such as metformin or sulfonylureas, have not provided adequate control. It is administered via subcutaneous injection, typically once daily before the first meal of the day. By stimulating insulin secretion and suppressing glucagon release, lixisenatide helps lower postprandial blood glucose levels. Additionally, it slows gastric emptying, contributing to a feeling of fullness and potentially aiding in weight management. It is often used in combination with other antidiabetic agents to achieve optimal glycemic control.
