Abstract

The aim of this study conducted in France was to confirm the efficacy and safety of the oral administration of carprofen (Rimadyl®) at 4 mg/kg once a day during four months in the treatment of clinically chronic osteoarthritis in dogs. One hundred and ten dogs with chronic clinical signs of osteoarthritis were enrolled. The overall severity of the osteoarthritis condition and the clinical signs of osteoarthritis were assessed using visual analogue scales (VAS) on days 0, 5, 30, 60, 90 and 120. During the same visits, owners were asked to perform their own efficacy assessment through the grading of seven parameters using categorical scales. Hematological analyses were performed on days 0 and 120. Clinical blood chemistry evaluations were performed on days 0, 5, 60 and 120. The percentage of dogs showing a positive treatment effect increased from 12% on day 5 to 74% on day 120. The mean VAS scores significantly decreased throughout the study (P ≤0.05). Gastrointestinal undesirable effects likely to be related to carprofen but with no harmful consequences were observed in 5% of treated dogs. No detrimental effects of the treatment on haematological, renal and hepatic parameters were observed. These results show that carprofen at 4 mg/kg once daily can be safely used over a 4 month period in the treatment of osteoarthritis in dogs and provides a steadily increasing improvement of the clinical signs.
