How Istamet Tablet ER works
Istamet XR 500 Tablet is a combination of two medicines: sitagliptin and metformin. Sitagliptin helps your pancreas produce more insulin, facilitates effective use of insulin by the body, and reduces excess sugar that your liver makes. Metformin is a biguanide that lowers glucose production in the liver, delays glucose absorption from the intestines, and increases the body's sensitivity to insulin. Together, they provide better control of blood sugar.
