GLUCOVANCE is a combination antidiabetic tablet. It contains the active ingredients metformin and glyburide. Metformin works by lowering the amount of glucose produced by the liver, reducing the amount absorbed during meals, and by making the body more sensitive to insulin. Glyburide works by stimulating the pancreas to release additional insulin.
