Hyaluronic acid (HA) is a mucopolysaccharide composed Of repeated
disaccharide units of glucuronic acid and N~acetylglucosamine.
The commercial HA is commonly a sodium form, called Sodium hyaluronate.
HA is widely presents in the extracellular matrix of animal tissues and vitreous
humor. Its main physiological function is water retention and lubrication.
HA has unique physicochemical properties and physiological functions.
It has been widely applied in the pharmaceutical industry. HA can be used as
viscoelastic materials in intraocular lens implantation and as fillers in articular
surgery against osteoarthritis, rheumatoid arthritis etc. It is also used as medium
in eye drops extensively. Furthermore, HA is helpful in preventing post~surgery
conglutination and improving wound healing. The compound as a result of its
reaction to other medicine may play a role of sustained release, thus achieving
the purpose of targeted and timed release. With the development of medical
science, HA will become more and more useful in the field of medicine.
