Dianorm OD 30mg (100 tablets) contains Vildagliptin, a medication used to manage type 2 diabetes. It works by inhibiting the DPP-4 enzyme, which helps increase insulin production and reduce sugar production in the liver, thus lowering blood sugar levels. The OD (Once Daily) formulation allows for convenient once-daily dosing. It helps maintain stable blood sugar levels when combined with a proper diet and exercise regimen.
