Pharmacology

Sodium hyaluronate is a polysaccharide which functions as a tissue lubricant. It is widely used in ophthalmic surgery because it forms a viscoelastic solution in water which makes it a suitable substitute for aqueous and vitreous humour.

Hyalgun 0.2% is administered by intra-articular injection. A treatment cycle consists of five injections given at weekly intervals. Some patients may experience benefit with three injections given at weekly intervals. Inject the full 2 ml in one knee only. If treatment is bilateral, a separate injection should be used for each knee.

The drug is contraindicated in patients with known hypersensitivity to hyaluronate preparations. Intra-articular injections are contraindicated in cases of past and present infections or skin diseases in the area of the injection site.
