About Metformin
Metformin is the first-line drug used worldwide for the treatment of type 2 diabetes mellitus, and Nigeria is no exception. Sold under popular brand names such as Glucophage, Dialon, and Panfor, Metformin belongs to a class of drugs called biguanides. It works primarily by reducing the amount of glucose (sugar) produced by the liver and by improving the body's sensitivity to insulin, the hormone responsible for moving sugar from the blood into the cells where it is used for energy. Unlike some other diabetes medications, Metformin does not cause weight gain, which is a significant advantage for the many Nigerians managing both diabetes and obesity.
