Metformin and vildagliptin is a fixed-dose combination medication used in the management of type 2 diabetes mellitus, particularly when monotherapy with either component alone does not provide adequate glycemic control. Metformin is a biguanide that decreases hepatic glucose production and improves insulin sensitivity, while vildagliptin is a dipeptidyl peptidase-4 (DPP-4) inhibitor that increases incretin levels, thereby enhancing glucose-dependent insulin secretion.
Pharmacokinetics
Pharmacokinetic parameters reported for healthy adult subjects after a single oral dose of fixed-dose metformin/vildagliptin tablets (typically 50 mg vildagliptin + 1000 mg metformin).
