The hyaluronic acid sodium widely exists in the Animal tissue intercellular substance and the eye vitreous body, the main physiological function is guarantees Shui Runhua and the osmotic pressure mediation. The hyaluronic acid sodium through increases the solution viscosity extension medicine in the eye surface dead time, enhances the medicine the biological exploitability, reduces the medicine cross-eye the irritating quality, increases the drop eye fluid the lubricating ability and comfortableness. The hyaluronic acid sodium and the eye organization have the very good biological compatibility, may use in many kinds of drop eye fluid or the ocular region nursing fluid. The anti-SARS antibacterial, the alleviation ocular region is weary; The treatment eye does the eye dry sickness; The increase hyaluronic acid sodium increases the drop eye fluid the lubricating ability and comfortableness.
A, containing sodium hyaluronate drops the eye under normal conditions, the natural existence of hyaluronate constitute a layer of mulch to corneal endothelial surface, animal and human corneal endothelial are combined with HA. Contains sodium hyaluronate drugs can be a long time to attach to the surface of the eye, eye tissue on drugs lasting and effective absorption. This makes the antibacterial effects of anti-inflammatory drugs can be fully effective, the local growth of harmful bacteria could not, in the eradication of the infection and eliminating local stimulation has an important significance.
B, sodium hyaluronate for dry eye treatment researchers visited the hyaluronate water retention. Find sodium hyaluronate can enhance the performance of corneal surface, thus increasing corneal moisturizer. Therefore, sodium hyaluronate drops can also be used for the treatment of dry eye. Sodium hyaluronate solution is available through the inhibition of the tear film of various ocular drying rupture ease symptoms. Researchers used tear film stability as an argument, 12 volunteers for the determination of the tear film break time, the concentration of sodium hyaluronate-effect relationship. Results show that the concentration of sodium hyaluronate solution 0.1% at least, in order to effectively mitigate dry eye symptoms.
