Gylan® Ultradex is a sterile 0.3% aqueous sodium hyaluronate solution with 2% dexpanthenol, free of preservatives.
The active substance, highly purified sodium hyaluronate, is produced by bacterial fermentation. Sodium hyaluronate is a physiological polysaccharide compound found both in eye tissues and in other human tissues and fluids.
A specific physicochemical property of sodium hyaluronate molecules is their strong ability to bind water molecules. Its aqueous solution (GYLAN) has the necessary viscosity and strong adhesive properties, effectively moisturizing the eye surface.
The solution also contains provitamin B5 (dexpanthenol), which has high water-binding capacity, further moisturizing the eyes and enhancing the hydration effect of sodium hyaluronate. Dexpanthenol also has anti- inflammatory and wound-healing properties, supporting faster regeneration of the eyes after trauma and surgery.
When applied, Gylan® Ultradex forms a thin, even film on the corneal epithelium, protecting the eyes from dryness, irritation, and inflammation of the anterior eye surface. The protective film acts instantly and provides long-term protection from dryness, burning, foreign body sensation, and irritation caused by computer work, air conditioning, or environmental factors. The precorneal tear film formed after instillation remains stable for a long time, is not washed away by blinking, and does not impair visual acuity.
Adequate eye surface hydration with Gylan® Ultradex helps normalize physiological processes and accelerates healing after trauma and surgery. Gylan® Ultradex effectively and rapidly relieves symptoms of dry eye syndrome of varying severity: eliminates foreign body sensation, burning, and stinging, reduces fatigue from intense visual strain, relieves discomfort, and helps maintain healthy eyes.
For regular contact lens wear, the use of Gilan® Ultradex is recommended, as it provides prolonged eye hydration due to its action being identical to natural tear fluid. The solution makes wearing hard or soft contact lenses more comfortable without depositing on the lens surface.
Gilan® Ultradex contains no preservatives, thus avoiding undesirable toxic effects on eye tissues and is well tolerated even with long-term use.
It provides longer-lasting effects due to the higher sodium hyaluronate content and increased solution viscosity (9.0–25.0 mPa·s).
Thanks to the special dropper design, the solution remains sterile throughout its shelf life after opening. Sterility after opening is ensured by the dropper’s construction — a special spring prevents solution from returning into the bottle from the remaining content after instillation, thereby avoiding contact with external solution. A sterilizing multilayer filter membrane in the air channel of the dropper further ensures sterility.
