Trusted by veterinarians all around the US
Synovetin OA has been used by 100s of veterinarians and helped 1000s of dogs regain their joyful, pain-free mobility. These results are consistent with clinical studies of dogs with mild, moderate, and severe elbow arthritis. 70% to 90% of these dogs responded positively to treatment based on both veterinarian and pet owner evaluations.*1
*Response can vary depending on the severity of the osteoarthritis.
A unique way to treat dog joint pain
Synovetin OA is a targeted treatment that uses microscopic radiotherapeutic particles to reduce inflammation inside the joint. Once there, it targets and safely eliminates harmful inflammatory cells that cause arthritis pain, destroy cartilage, and cause the disease to worsen. This same treatment approach has been safely and effectively used for decades to treat arthritis in people in countries around the world.

In the joint fluid of an arthritic joint, inflammatory cells drive pain and progression of the disease. Inflammation is the source of pain–where it begins. The inflammatory cells in inflamed joints produce substances that cause even more inflammation and damage to the joint. This is called “the vicious cycle of inflammation” and if left untreated, it causes ongoing inflammation, pain, and damage to the cartilage that lines the joint.
In most cases, you should begin to see improvement in your dog’s mobility within a few weeks, depending on the severity of arthritis. Some dog owners see results almost immediately, while in other instances of severe arthritis, it can be up to 2 months. This improvement should continue over time as Synovetin OA works inside the joint to reduce inflammation.
Synovetin OA is a treatment that consists of microscopic particles of the unique isotope tin-117m. These targeted particles emit a form of mild radiation energy that inactivates the harmful cells causing inflammation within the joint and the tissues surrounding the joint (called the synovium) and that drive the loss of cartilage. This activity helps to restore joint health and provides very long lasting pain relief without the systemic side effects that can commonly occur with daily and monthly dog arthritis drugs.
Synovetin OA is administered directly into the arthritic joint where it remains and works locally to eliminate inflammation–the driver of pain and progression of arthritis. It does not travel through the dog’s body and therefore causes no systemic side effects. This is in contrast to pain drugs such as daily NSAIDs or monthly injections, which are metabolized systemically in the dog’s body and have known, significant side effects.
