What is Euflexxa

EUFLEXXA is a gel-like, elastic, sterile product containing natural, highly purified hyaluronan (hye-a-loo-ROE-nan), (also known as sodium hyaluronate). Hyaluronan is a natural substance found in the body and is present in particularly high amounts in joint tissues and in the fluid that fills the joints. The body’s own hyaluronan acts like a lubricant and a shock absorber in the joint, and is needed for the joint to function properly. Osteoarthritis is a condition that involves the wearing down of cartilage (the protective covering on the ends of your bones).

In osteoarthritis, there may not be enough hyaluronan, and there may be a decrease in the quality of the hyaluronan in joint fluid and tissues.

EUFLEXXA comes in pre-filled syringes containing 2 ml (about half a teaspoon) of product. EUFLEXXA is given by injection directly into the knee joint.

What is Euflexxa Used For

EUFLEXXA is used to relieve knee pain due to osteoarthritis. It is used for patients who do not get enough relief from simple pain medications such as acetaminophen or from exercise and physical therapy.

What are the Benefits of Euflexxa

A clinical study involving 321 patients between the ages of 50 and 80 years of age with knee pain due to osteoarthritis was performed in Germany. The study investigated the safety and effectiveness of EUFLEXXA. The patients were placed in one of two groups. One group was given an injection of EUFLEXXA into one or both knee joints once a week for 3 weeks. The second group was given an injection of another commercially available hyaluronan once a week for 3 weeks.

Pain, stiffness and function of the knee joint and patients’ and doctors’ judgment of the success of treatment were measured for 12 weeks. Patients with osteoarthritic knee joint pain, who had not obtained pain relief with other medications, experienced pain relief from the EUFLEXXA injections into the knee joint, similar to those patients who received injections of the other hyaluronan.
