Clinical evaluation of amitraz for treatment of canine scabies.

Abstract

A liquid concentrate formulation of amitraz (Mitaban: Upjohn) was used to topically treat 181 dogs with scabies, at an active drug level of 250 ppm, or 10.6 ml of concentrate in 2 gal water. After the dogs were clipped and bathed, the diluted medication was applied and allowed to dry on the animal. All treated dogs were clinically improved and 97.8% cured after a single treatment; 3 dogs required 2 treatments and 1 dog 3 treatments. Otodectes cynotis and Cheyletiella yasguri in several dogs were also cleared after 1 treatment. Mild, transient sedation occurred in 12.4% of treated dogs, with transient vomiting, increased appetite and diarrhea in less than 1%.
