The primary objective of equine joint therapy should be to block the further release of inflammatory mediators while decreasing the effect of the mediators already released.
Legend delivers proven efficacy
In field studies, overall clinical improvement was judged to be excellent or good in 90% of the cases treated intravenously with Legend and 96 % of those treated intra-articularly with Legend.1
Legend reduces joint inflammation and the resulting pain and lameness by decreasing the production and release of inflammatory mediators.
The interleukin-1-driven production and release of prostaglandin and also the protein count in synovial fluid is decreased for 45 days following intravenous injection, indicating a beneficial effect long after intravenous administration. 2
Legend is pure Hyaluronic Acid (HA)
HA stimulates endogenous HA production.
HA administration stimulates synoviocytes to produce endogenous high-molecular-weight HA.3
HA provides a physical barrier.
HA contributes to the steric exclusion of plasma components and leukocytes. 2
HA decreases the presence of inflammatory mediators.
HA decreases the interleukin-1-driven production and release of prostaglandin E2. PgE2 causes cartilage destruction.4 HA scavenges oxygen-derived free radicals.5
Legend is micro-filtered for purity
Derived naturally through a unique biofermentation process developed by Bayer, Legend is pure hyaluronic acid. After biofermentation, Legend is purified through a 12-step microfiltration process to remove impurities and foreign proteins. Foreign proteins increase the potential for joint flares.
Treat noninfectious synovitis with the proven performance of Legend:
The only FDA-approved joint therapy for both intravenous and intra-articular administration, so you can choose the treatment method to meet the horse's needs. Produced through biofermentation and purified though a 12-step microfiltration process to help reduce the presence of foreign proteins. Legend reduces joint inflammation and the resulting pain and lameness by decreasing the production and release of inflammatory mediators.2 Legend is backed by extensive independent university studies and Bayer research. Up to three weekly intravenous doses of Legend will treat all affected fetlocks and carpi of the horse.
