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.
