Basic Information


Sodium hyaluronate is the sodium salt of hyaluronic acid, a glycosaminoglycan found in various connective, epithelial, and neural tissues. Sodium hyaluronate, a long-chain polymer containing repeating disaccharide units of Na-glucuronate-N-acetylglucosamine, occurs naturally on the corneal endothelium, bound to specific receptors for which it has a high affinity. The polyanionic form, commonly referred to as hyaluronan, is a visco-elasticpolymer normally found in the aqueous and vitreous humour. 


Medical uses

Sodium hyaluronate is used as a viscosupplement, administered through a series of injections into the knee, increasing the viscosity of the synovial fluid, which helps lubricate, cushion and reduce pain in the joint. It is generally used as a last resort before surgery and provides symptomatic relief, by recovering the viscoelasticity of the articular fluid, and by stimulating new production from synovial fluid. Use of sodium hyaluronate may reduce the need for joint replacement. Injections appear to increase in effectiveness over the course of four weeks, reaching a peak at eight weeks and retaining some effectiveness at six months, with greater benefit for osteoarthritis than oral analgesics. It may also be effective when used with other joints.

Sodium hyaluronate may also be used in plastic surgery to reduce wrinkles on the face or as a filler in other parts of the body. It may be used in ophthalmology to assist in the extraction of cataracts, the implantation of intraocular lenses, corneal transplants, glaucoma filtration, retinal attachment and in the treatment of dry eyes.

Sodium hyaluronate is also used to coat the bladder lining in treating interstitial cystitis.


Contraindications

Sodium hyaluronate is contraindicated for people who are sensitive to hyaluronate preparations, or when there are infections or skin disease at the injection site.


Adverse effects

Adverse effects are relatively rare when used to treat the joints.

When used in ophthalmological procedures, sodium hyaluronate may cause postoperative inflammation, corneal edema or decompensation, and short-term increases in intraocular pressure.


Mechanism of action

Sodium hyaluronate functions as a tissue lubricant and is thought to play an important role in modulating the interactions between adjacent tissues. Sodium hyaluronate is a polysaccharidewhich is distributed widely in the extracellular matrix of connective tissue in man. It forms a viscoelastic solution in water which makes it suitable for aqueous and vitreous humor inophthalmic surgery. Mechanical protection for tissues (iris, retina) and cell layers (corneal, endothelium, and epithelium) are provided by the high viscosity of the solution. Elasticity of the solution assists in absorbing mechanical stress and providing a protective buffer for tissues. This viscoelasticity enables maintenance of a deep chamber during surgical manipulation since the solution does not flow out of the open anterior chamber. In facilitating wound healing, it is thought that it acts as a protective transport vehicle, taking peptide growth factors and other structural proteins to a site of action. It is then enzymatically degraded and active proteins are released to promote tissue repair. Sodium hyaluronate is being used intra-articularly to treat osteoarthritis.


Physical and chemical properties

Sodium hyaluronate is an ophthalmic agent with viscoelastic properties that is used in joints to supplement synovial fluid.
