RESUMO
BACKGROUND: There are few licensed options for the treatment of canine sarcoptic mange. OBJECTIVE: To evaluate the efficacy of fluralaner in dogs with sarcoptic mange infestation. ANIMALS: Seventeen dogs with a diagnosis of Sarcoptes scabiei based on positive skin scrapings. METHODS: A single dose of oral fluralaner was administered according to the manufacturer's instructions. Assessments of pruritus and lesions were performed every 7 days for 1 month. RESULTS: By Day 14 post-treatment, skin scrapings from all dogs were negative for mites. At the beginning of the study there was a negative correlation between body weight of the subject and pruritus [Pearson correlation coefficient (PCC) = -0.396, P = 0.007] and a positive correlation between pruritus and lesion severity (PCC 0.755, P = 0.0001). Significant decreases in lesion size and pruritus were observed within the first 14-21 days, respectively, and improvement in these parameters continued until the end of the study at Day 28. CONCLUSION: Fluralaner was effective in eliminating scabies mites within 14 days and significantly resolved the clinical signs associated with sarcoptic mange within 21 days after a single dose.
