Sterile otic solution for dogs and cats containing Tris-EDTA and N‑Acetylcysteine (NAC) to support biofilm disruption and enhance the effectiveness of topical ear treatments. Tris-EDTA acts against bacteria within biofilms and increases membrane permeability, while NAC has mucolytic action that weakens the biofilm matrix. Well tolerated and non-ototoxic, this ready-to-use 120 ml bottle includes a syringe for dosing. Use by instilling into the ear canal and massaging the base of the ear, or apply to skin until fully soaked, repeating as needed or per veterinary guidance.
