What is the primary function of glucophage (Metformin)?

The primary function of Glucophage (Metformin) is to reduce blood sugar levels, primarily in individuals with type 2 diabetes. Metformin works mainly by decreasing hepatic glucose production and enhancing insulin sensitivity, which leads to improved glucose uptake by the tissues. This results in lower overall blood glucose levels.

While enhancing insulin action is one part of Metformin's mechanism—effectively making the body's own insulin work more efficiently—its most predominant and clinically recognized effect is the significant reduction in blood glucose levels.

The other options, such as stimulating insulin production or increasing glucose absorption in the intestine, do not accurately reflect Metformin's primary role. Metformin does not stimulate insulin secretion from the pancreas, which is a function seen with other diabetic medications. Additionally, it does not increase glucose absorption; instead, it contributes to lowering blood glucose levels through mechanisms that improve insulin sensitivity.
