Legend®
(hyaluronate sodium)
First and only FDA-approved hyaluronic acid joint therapy currently available for both intravenous and intra-articular administration.
Details
LEGEND Injectable Solution is indicated in the treatment of joint dysfunction of the carpus or fetlock in horses due to non-infectious synovitis associated with equine osteoarthritis. Equine osteoarthritis can happen in any age and any discipline due to everyday wear and tear. It is permanent and can lead to early retirement and quality-of-life issues in horses.
The active ingredient in LEGEND, hyaluronic acid (HA), decreases the presence of inflammatory mediators in the joint, improves synovial fluid quality, and reduces the degree of lameness. These improvements are seen whether LEGEND is administered by intravenous (I.V.) or intra-articular (I.A.) injection. LEGEND hyaluronate sodium injectable is sterile, pyrogen-free and FDA-approved.
Not for use in humans. Keep this and all other drugs out of reach of children. The safety of LEGEND has not been evaluated in breeding stallions or in breeding, pregnant or lactating mares. LEGEND 4 mL and LEGEND Multi-Dose Injectable Solution are administered by intravenous injection only.
