Description
Medical device based on 3% hypertonic saline, pH controlled, and 6% N-acetylcysteine. Indicated to facilitate the fluidification and mechanical removal of mucous and/or mucopurulent secretions stagnant in the nasal cavities (acute, subacute and slow-resolving rhinitis, chronic and muco-crusty rhinitis, vasomotor rhinitis) and in the paranasal sinuses (acute and chronic sinusitis), improving symptoms and the course of acute, subacute and chronic inflammations of the upper airways.
Viscoflu nasal spray fluidifies thick and viscous mucus through the physical/mechanical action of its components:
-Hypertonic sodium chloride solution (buffered): hypertonic saline solutions applied directly to the respiratory mucous membranes draw water by osmosis from the intracellular to the extracellular compartment. In this way, they increase the water content of the mucus lining the epithelium, fluidifying it and facilitating its removal.
N-acetylcysteine: an acetylated variant of the amino acid cysteine, it has mucolytic activity which it exerts by 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 viscosity to mucus, thus depolymerizing them.

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

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

Instructions for use
For proper use, remove the protective cap, tilt your head slightly backwards, gently place the dispenser nozzle at the entrance of the nostril, press the base of the dispenser with two fingers and spray 2-3 consecutive times.
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 picture to be treated.
