Randomised double-blind, positive-controlled trial to assess the efficacy of glucosamine/chondroitin sulfate for the treatment of dogs with osteoarthritis.
Thirty-five dogs were included in a randomised, double-blind, positive controlled, multi-centre trial to assess the efficacy of an orally-administered glucosamine hydrochloride and chondroitin sulfate (Glu/CS) combination for the treatment of confirmed osteoarthritis of hips or elbows. Carprofen was used as a positive control. Dogs were re-examined on days 14, 42 and 70 after initiation of treatment. Medication was then withdrawn and dogs were re-assessed on day 98. Response to treatment was based on subjective evaluation by participating veterinarians who recorded their findings at each visit. Dogs treated with Glu/CS showed statistically significant improvements in scores for pain, weight-bearing and severity of the condition by day 70 (P<0.001). Onset of significant response was slower for Glu/CS than for carprofen-treated dogs. The results show that Glu/CS has a positive clinical effect in dogs with osteoarthritis.
