Jentin Met Tab is a diabetic management medicine. Sitagliptin and metformin HCl are the two main active components in each tablet. Sitagliptin works by raising the body's levels of incretin hormones, which aid with blood sugar regulation. Metformin HCl works by boosting the insulin sensitivity of muscle and fat cells and reducing the quantity of glucose produced by the liver. These two substances act together to improve glycemic management and lower blood sugar levels. Individuals who have been unable to achieve adequate glycemic control through diet and exercise alone are frequently prescribed the medication. The medicine should be taken as directed by the doctor.
