Galvus (vildagliptin) is an oral antidiabetic medication used to treat type 2 diabetes. It belongs to a class of medications called dipeptidyl peptidase-4 (DPP-4) inhibitors. Galvus works by increasing the levels of incretin hormones in the body, which helps to lower blood sugar levels by stimulating the pancreas to produce insulin and reducing the amount of sugar produced by the liver.
