Viscoflu Hypertonic Saline Nasal Spray is a medical device made from 3% hypertonic saline solution at controlled pH and 6% N-acetylcysteine. It is indicated to facilitate the fluidification and mechanical removal of mucus and/or muco-purulent secretions stagnant inside the nasal cavity (acute, subacute and slow -resolution rhinitis; chronic and muco-crusty rhinitis; vasomotor rhinitis) and inside the paranasal sinuses (acute and chronic sinusitis), improving the symptoms and course of acute, subacute and chronic inflammation of the upper respiratory tract.
