EUFLEXXA® is a treatment to help relieve knee pain due to osteoarthritis (OA) and is used by thousands of people to help manage OA knee pain and stay active. Containing 1% fermentation-derived sodium hyaluronate, EUFLEXXA is intended for intra-articular injection into the knee. Both EUFLEXXA, and sodium hyaluronate are manufactured in our facilities in Be'er Tuvia.


Sodium hyaluronate (NaHA) is a naturally occurring polysaccharide, ubiquitous in nature and chemically identical in all species, which is found in the synovial fluid surrounding knee and other joints, in the vitreous and aqueous humor of the eye, in skin and in other organs. BTG’s NaHA is a highly purified, high molecular weight preparation, and, in contrast to other NaHA products extracted from avian sources, is produced using an efficient and proprietary bacterial fermentation process.


EUFLEXXA® has regulatory approval in more than 30 countries, and is marketed in North America, Europe and Asia. In Israel, the product is marketed under the trade name Arthrease® by Ferring Pharmaceuticals Ltd.
