Positive CBD results in treating canine OA pain

The study – by Matthew Halpert’s group at Baylor College of Medicine in Houston – also showed that presenting the drug within a lecithin-based liposome improved bioavailability, allowing the use of a much lower dose, reducing the likely cost and potential risks of long-term treatment.

Double-blind trial

Dr Halpert’s study recruited 20 dogs owned by clients of Sunset Animal Hospital in Houston to receive either 20mg/day or 50mg/day of pure CBD, or the liposomal CBD at 20mg/day in a four-week placebo-controlled, double-blind trial.

Saying the results were encouraging, he added: “Nine of the 10 dogs in the high CBD dose and liposomal CBD groups showed benefits that remained for two weeks after the treatment stopped.”

No detectable changes occurred in either the low dose “naked” CBD or the control group.

Pain index

The improvements were detected by team vet Shonda Wesson in her assessment of signs of pain when the dogs were walking, running and lying down.

Her findings showed good agreement with the owners’ evaluation using the Helsinki Chronic Pain Index – a validated quality of life tool for measuring treatment response in dogs with OA.
