To assess the impact of oral cannabidiol (CBD) administration in addition to standard antiepileptic remedy on seizure frequency in dogs with idiopathic epilepsy.

Design and style:

Randomized blinded controlled clinical trial.


26 client-owned dogs with intractable idiopathic epilepsy.


Dogs have been randomly assigned to a CBD (n = 12) or placebo (14) group. The CBD group received CBD-infused oil (two.five mg/kg [1.1 mg/lb], PO) twice day-to-day for 12 weeks in addition to current antiepileptic treatment options, and the placebo group received noninfused oil beneath the similar circumstances. Seizure activity, adverse effects, and plasma CBD concentrations have been compared in between groups.


two dogs in the CBD group created ataxia and have been withdrawn from the study. Immediately after other exclusions, 9 dogs in the CBD group and 7 in the placebo group have been integrated in the evaluation. Dogs in the CBD group had a important (median adjust, 33%) reduction in seizure frequency, compared with the placebo group. Even so, the proportion of dogs regarded as responders to remedy (≥ 50% lower in seizure activity) was related in between groups. Plasma CBD concentrations have been correlated with reduction in seizure frequency. Dogs in the CBD group had a important enhance in serum alkaline phosphatase activity. No adverse behavioral effects have been reported by owners.


Even though a important reduction in seizure frequency was accomplished for dogs in the CBD group, the proportion of responders was related in between groups. Offered the correlation in between plasma CBD concentration and seizure frequency, more investigation is warranted to decide irrespective of whether a greater dosage of CBD would be powerful in minimizing seizure activity by ≥ 50%.
