Gliclazide modified release (MR) belongs to the class of medications called oral hypoglycemics. It is used for the control of blood glucose in people with type 2 diabetes. It is used when diet, exercise, and weight reduction have not been found to control blood glucose well enough without medication. Gliclazide MR increases the amount of insulin released by the pancreas and helps the body use insulin more efficiently.
