The most effective systemic treatment in cats with otodectic mange: A critically appraised topic

Otodectic mange is one of the most common ectoparasitic diseases in cats and the most common cause of feline otitis externa. It is particularly prevalent in young cats between 3 and 6 mo of age and is a veterinary concern, especially in catteries, due to its highly contagious nature. Although there is a risk of overdiagnosis if based solely on cerumen, it is not difficult to identify Otodectes cynotis if there is a clinical suspicion in a young cat. Considering the variety of available acaricidal molecules, as well as the need to use the most effective treatment, the present article reviews evidence comparing various types of systemic treatment for otodectic mange in cats.

Isoxazolines (sarolaner, fluralaner, or esafoxolaner) or similar molecules such as tigolaner (a bispyrazole) and macrocyclic lactones (selamectin, eprinomectin, or moxidectin) can lead to parasitological cure and improvement of clinical signs associated with otodectic mange in cats, with rare, mainly cutaneous side effects with mild, autoresolving lesions.

Similarities in the clinical and parasitological efficacy of these substances highlight the need for comparative studies that could allow identification of the most efficacious product.
