What is metformin and how does it work?

Metformin is an oral medicine used to treat type 2 diabetes by helping to regulate blood sugar levels. It works by decreasing the amount of sugar produced by the liver, delaying absorption of sugar by the stomach and intestines and also helps the body to better utilise the lower amount of insulin produced by people with type 2 diabetes. Metformin is the most widely used type 2 diabetes treatment in the world. Metformin is also known under brand names such as Glucophage®, Glucophage® SR, Metsol® and Bolamyn® SR. Metformin tablets are not recommended for type 1 diabetes, please seek professional advice from your doctor for type 1 treatment options.

How does metformin achieve the desired blood sugar levels?

Metformin is biguanide which is a term used for oral type 2 diabetes medicine used to prevent glucose being produced in the liver. Bigguanides improve the human body’s sensitivity to insulin and decrease the sugar levels absorbed by the intestines. They do this by preventing the production of glucose from the liver, food and increasing its uptake by the body tissue.
