[Pharmacology and Toxicology]
Sodium hyaluronate is a natural polymer compound, which is an important component of tissue matrix. It has good viscoelasticity and has a protective effect on cornea. Combined with fibronectin, it promotes the connection and extension of corneal epithelial cells and accelerates corneal wound healing. In addition, sodium hyaluronate molecules have strong hydrophilic ability and lubrication, which can stabilize the tear film, prevent keratoconjunctival dryness and reduce the friction of eye tissue, and relieve the discomfort symptoms of dry eye.
[Pharmacokinetics]
After 14C-labeled 0.1 sodium hyaluronate eye drops are instilled in rabbits, strong radioactivity can be detected in conjunctiva, external eye muscle and sclera within 0.5h, with the strongest radioactivity in conjunctiva, weak radioactivity can be detected in cornea, retina and choroid, while no radioactivity can be detected in aqueous humor, iris, ciliary body, crystal and vitreous. The radioactivity of the conjunctiva dropped below the threshold after 24h. Healthy people were given 0.1 sodium hyaluronate eye drops on the first day of monocular eyes, and were changed to 0.5 sodium hyaluronate eye drops on the second day, 1 drop once, 5 times a day, and continued to use sodium hyaluronate eye drops on the third to ninth days, 13 times a day, for 7 consecutive days. The concentration of sodium hyaluronate in serum was determined at the beginning of the drop, on the third day, the ninth day and the tenth day, and all of them were below the detection limit (10?g/ml), which was the same as that of the drop.
