Antidiabetic medications are drugs used to manage and control blood sugar levels in individuals with diabetes. They help improve the body's response to insulin or increase insulin production, which is crucial for regulating glucose levels in the bloodstream. There are several classes of antidiabetic medications, including metformin, sulfonylureas, and GLP-1 receptor agonists. Each class works differently, targeting various aspects of glucose metabolism. Proper use of these medications, along with lifestyle changes like diet and exercise, can significantly improve the quality of life for those living with diabetes.
