GENERIC NAME: sodium hyaluronate (hyaluronan) intra-articular injection
BRAND NAME: Hyalgan, Supartz, Euflexxa, Orthovisc
DRUG CLASS AND MECHANISM: Hyaluronic acid is a natural chemical that is found in almost all species of animal and in various parts of the human body. It works as a biological lubricant, reducing friction between adjacent tissues. It is present in high amounts in joints and synovial fluid (the fluid that fills the knee joint).
Sodium hyaluronate is used for the treatment of pain due to osteoarthritis of the knee in patients who do not get adequate relief from simple pain medicines or from exercise and physical therapy. It is administered by injection directly into the knee joint (intra-articular injection).
The exact mechanism by which sodium hyaluronate products work is not known. The synovial fluid in the knees helps lubricate and cushion our joints during movement. Sodium hyaluronate is the major component in the synovial fluid. People with osteoarthritis do not have enough hyaluronic acid in their synovial fluid. It is thought that sodium hyaluronate injection helps restore synovial fluid, thereby reducing some of the pain and discomfort associated with osteoarthritis.
The first sodium hyaluronate injection was approved in the US in 1997.
PRESCRIBED FOR: Sodium hyaluronate is used for the treatment of pain due to osteoarthritis of the knee in patients who do not get adequate relief from simple pain medicines (for example, acetaminophen [Tylenol and others]) or from exercise and physical therapy.
