Tris-NAC is an ear and skin flush containing two highly synergistic and innovative active substances that break down bacterial and fungal biofilms. Tris-EDTA has an antibacterial action and helps prevent the formation of new biofilm, while N-Acetylcysteine breaks down existing biofilm. It can be used before applying medicated drops when bacterial resistance is a concern. Tris-NAC can be used in conjunction with Otodine® and products from the Peptivet range to help manage ear cases.  Clean the ear first with Otodine. For use in dogs and cats.
