Description
Medical device based on 3% hypertonic saline, with controlled pH, and 6% N-acetylcysteine. Indicated to facilitate the liquefaction and mechanical removal of mucous and/or mucopurulent secretions stagnant in the nasal cavities (acute, subacute and slowly resolving rhinitis, chronic and muco-crusted rhinitis, vasomotor rhinitis) and in the paranasal sinuses (acute and chronic sinusitis), improving the symptoms and course of acute, subacute and chronic inflammation of the upper airways.
Viscoflu nasal spray thins thick, sticky mucus through the physical/mechanical action of its components:
- Hypertonic sodium chloride solution (buffered) : Hypertonic saline solutions applied directly to the respiratory mucosa draw water from the intracellular to the extracellular compartment by osmosis. They thus increase the water content of the mucus lining the epithelium, liquefying it and facilitating its removal.
N-acetylcysteine : An acetylated variant of the amino acid cysteine, it possesses mucolytic activity through direct contact with mucus. This activity depends on the presence of sulfhydryl radicals in the molecule, capable of breaking the disulfide bonds of mucoproteins that give mucus viscosity by depolymerizing them.

Composition
N-acetylcysteine, sodium chloride; excipients: sodium hydroxide, sodium edetate, purified water.

A 30 ml bottle contains:
N-acetylcysteine	1.8 g
Sodium chloride	0.9 g

How to use
For correct use, remove the protective cap, tilt your head slightly back, gently position the spray nozzle at the entrance of your nostril, press the base of the nozzle with two fingers and spray 2-3 times in a row.
Clean the dispenser and replace the protective cap. Shake well before use.
The recommended dose is 2-3 sprays per nostril, two or three times a day, for no more than 10 consecutive days, depending on the clinical condition being treated. The treatment may be repeated several times throughout the year, but use of the product should be interrupted for at least one week between each treatment. Use the product within 2 months of first opening.
