SUPARTZ (P980044) is indicated for treatment of pain in osteoarthritis (OA) of the knee in patients who have failed to respond adequately to conservative non-pharmacologic therapy and simple analgesics, e.g., acetaminophen. SUPARTZ is a sterile, viscoelastic, non-pyrogenic solution (pH of 6.8-7.8) of highly purified, high molecular weight hyaluronic acid (HA) (620 000-1 170 000 daltons). HA, which is extracted from rooster combs, is a polysaccharide containing repeating disaccharide units of glucuronic acid and N-acetylglucosamine. HA is a common constituent of the extracellular matrix of connective tissues. SUPARTZ is supplied sterile in single-use, pre-filled, disposable plastic syringes, each containing 25 mg of HA dissolved in a Phosphate Buffered Saline (PBS) solution (2.5 mL of 1.0% solution).
A sterile viscous/elastic solution or gel (e.g., comprised of hyaluronic acids and their polymeric derivatives) intended to be injected into joints (particularly large, load-bearing joints such as the hip or knee) to help cushion the joint, especially in cases of endogenous synovial fluid reduced viscosity from degenerative disease.
