Glymidine sodium is primarily used in the field of medicine as an oral antidiabetic agent. It helps in managing blood sugar levels in individuals with type 2 diabetes by stimulating insulin secretion from the pancreas. This makes it effective in controlling hyperglycemia, especially when dietary changes and exercise alone are insufficient. Additionally, it is sometimes combined with other antidiabetic medications to enhance its efficacy. Glymidine sodium is particularly useful for patients who may not respond well to other hypoglycemic drugs, offering an alternative treatment option. However, its use requires careful monitoring to avoid potential side effects such as hypoglycemia.
