Cartrophen Vet

Cartrophen Vet (100mg/mL of pentosan polysulfate sodium or PPS) is a treatment for osteoarthritis (OA, also known as degenerative joint disease or DJD) and related musculoskeletal disorders in dogs. It provides pain relief by acting on the pathology within the joint that causes pain and lameness. Cartrophen Vet has many sites of action within the underlying processes of the arthritis disease which helps maintain joint health including preserving joint cartilage. It is therefore classified as a disease modifying osteoarthritis drug (DMOAD).

Cartrophen Vet is a prescription only, injectable, polysulfated polysaccharide of plant origin.

Cartrophen Vet will benefit acute through to chronic OA due to the progressive nature of this disease. Early intervention with Cartrophen Vet in acute injuries will maximise the restoration of normal connective tissue function.

Cartrophen Vet is a treatment, which has activity that works to correct the underlying metabolism of the OA. By re-balancing the metabolic processes it preserves joint health and subsequently provides relief from the clinical signs of OA. Cartrophen Vet’s changes to the disease are evident in its long-term effects. Benefits are received well beyond the treatment period of 4 weeks with repeat treatments in some cases at one-year intervals.

With 20% of dogs over one year of age suffering from OA and 60% of lameness in the horse related to OA, Cartrophen Vet and DMOAD represent the rational approach to the medical treatment of OA.
