A randomized, blinded, placebo-controlled study was conducted to assess the efficacy of a new 0.025% budesonide leave-on-conditioner (Barazone) in controlling the clinical signs of canine atopic dermatitis (AD). Twenty-nine dogs with AD were randomly allocated to receive 3 weeks of once-weekly treatment with either Barazone or Placebo and then were crossed-over to receive the alternative treatment for a further 3 weeks. At the start and end of each treatment phase, referring veterinarians performed a dermatological and general physical examination on each dog, assigned a Lesional Score, collected blood for haematological and biochemical analyses and rated the dog's overall tolerance to the preceding treatment. Owners assessed their dog's level of pruritus and quality of life (QoL) daily, using visual analogue scales labelled with behavioural descriptors. Barazone improved skin lesions (P = 0.02) and QoL (P < 0.001) and reduced pruritus (P ≤ 0.002) compared with treatment with Placebo. There were no significant differences in the tolerance scores and only minor differences in the general physical examination findings and haematological and biochemical parameters between dogs receiving Barazone or Placebo. This study demonstrated that Barazone, applied once weekly at 1 g/kg for 3 weeks, was an efficacious treatment for the control of the clinical signs of AD in dogs.
