What is the purpose of the medication metformin?

The purpose of metformin is to manage type 2 diabetes by lowering blood sugar levels. Metformin belongs to the class of medications known as biguanides and is primarily prescribed to improve insulin sensitivity and reduce glucose production in the liver. It helps to enhance the uptake of glucose by the muscles and decreases the absorption of glucose from the gastrointestinal tract, leading to lower blood sugar levels in individuals with type 2 diabetes. This mechanism not only aids in glycemic control but also often contributes to weight stability or modest weight loss, which can be beneficial for patients with this condition.

This therapeutic action makes metformin a cornerstone treatment for type 2 diabetes, distinguishing it from options focused on conditions unrelated to blood glucose management.
