  1. Kombiglyze XR


Saxagliptin and metformin combination is used with diet and exercise to treat high blood sugar (glucose) levels in patients with type 2 diabetes. Saxagliptin helps to control blood sugar levels by making the pancreas gland release more insulin. It also signals the liver to stop producing sugar when there is too much sugar in the blood. Metformin reduces the absorption of sugar from the stomach, reduces the release of stored sugar from the liver, and helps your body use sugar better. This medicine does not help patients who have insulin-dependent or type 1 diabetes.

This medicine is available only with your doctor's prescription.

This product is available in the following dosage forms:

  • Tablet, Extended Release
