Using Noltrex®Vet for the Standardbred Racehorse

Note:  June 13, 2022 – Nucleus ProVets is aware of the proposed HISA regulations regarding the timelines for use of polyacrylamide hydrogels.  To discuss these regulations further please contact our Veterinary Director, Craig T. Roberts, DVM, at

Medication rules, a long career span, and frequent competitions mean that the Standardbred racehorse requires the highest level of attention to their joint health. Joint injections should be predictable and planned events, not last-minute problems at a critical time in a racing career. Similarly, unreliable responses to joint therapy are a major source of frustration when a training program is built on dependability.

Initially considered a therapy to use when all else failed, Noltrex®Vet’s dependable results in these impossible situations has led to more veterinarians using it earlier in the management of joint conditions. Adding it to a joint management protocol often minimizes the frequency that other therapies require to reliably maintain an athlete over time.

For long duration joint lubrication in horses, use Noltrex®Vet.

  • Noltrex®Vet is not a drug
  • Fewer injections reduce the risk of complications from repeated injections
  • Noltrex®Vet is reabsorbed safely by your horse’s body, leaving no residue
  • Any joint can potentially benefit from Noltrex®Vet
  • Horses with Cushing’s Syndrome (PPID), metabolic issues, gastric ulcers (EGUS), or prior laminitis can all be treated safely with Noltrex®Vet


Hear why veterinarians and owners consider Noltrex®Vet an invaluable tool for managing joint conditions in standardbred racehorses.

  • “After reviewing the research on polyacrylamide gels, I was anxious to try this innovative product. Now, with great results in some difficult cases (and many more over the years), I continue to use Noltrex®Vet as a necessary tool in my practice.”

    John Hennessey, DVMHennessey Equine, Rockwood, Ontario
  • We had a 10-year-old Standardbred who was out of work as a pacer under saddle with bilateral stifle injury. He had been lame for 2 years. Repeated steroid and HA injections provided 4 weeks of relief at most. In the summer of 2016 our veterinarian recommended injecting Noltrex®Vet into both stifles. He was so young and talented we felt we had nothing to lose. He went on to go sound and back to work and quickly returned to the winner circle!””
