What is Galvumet?

Galvumet is a combination of two medicines, vildagliptin and metformin, in a single tablet.  It is used to treat type 2 diabetes. Galvumet helps to control the blood glucose level by making the pancreas produce more insulin and less glucagon (effect of vildagliptin) and also by helping the body to make better use of the insulin it produces (effect of metformin). In New Zealand Galvumet is available as tablets. Read more about type 2 diabetes
