Final answer:
Metformin is used for the maintenance of a person's blood glucose levels, particularly in the treatment of type 2 diabetes, by reducing glucose production in the liver, increasing tissue sensitivity to insulin, and decreasing glucose absorption from the intestines.
Step-by-step explanation:
The therapeutic use of metformin is to maintain a person's blood glucose levels. This medication is commonly prescribed for individuals with type 2 diabetes as a means to control high blood glucose. It works through several mechanisms, such as reducing the amount of glucose the liver produces and released into the bloodstream (known as gluconeogenesis), increasing the sensitivity of body tissues to insulin so that more glucose is taken up from the bloodstream, and reducing the intestinal absorption of glucose, which collectively contribute to lower blood glucose levels.
Metformin may be prescribed as part of a broader diabetes management plan that includes diet and physical activity. This medication has proven to be effective in improving blood glucose levels in those with type 2 diabetes and demonstrates a good safety profile when used as directed under medical supervision.
