Virbac has launched Cortotic, a corticosteroid-only treatment for the clinical signs associated with canine otitis externa, without an antimicrobial.

Cortotic contains hydrocortisone aceponate (HCA), a diester glucocorticosteroid to reduce inflammation.

In a clinical field study, published in Veterinary Dermatology, Cortotic was shown to be as effective in treating acute otitis as a fixed-combination product containing a corticosteroid, an antibiotic and an antifungal, with an equivalent improvement of clinical and cytological scores1.

A secondary reduction of bacterial and yeast overgrowth was demonstrated and a concomitant treatment with an antimicrobial was unnecessary.

The product was shown to provide rapid relief from clinical signs, pruritus and pain1.

Virbac says the lipophilic nature of the HCA diester provides enhanced penetration into the skin, a reservoir effect and low plasma availability for high local activity with reduced systemic secondary effects2.

Chris Newark, Product Manager at Virbac said: "With Cortotic we’re excited to offer clinicians the ability to reduce antimicrobial usage when treating otitis externa in dogs, whilst offering the same efficacy as a fixed-combination product.

"The product’s easy administration also makes it an attractive choice for pet owners with 94% of owners stating that they would choose to use Cortotic again3".

Cortotic is presented in an ear spray device with atraumatic cannula, which delivers a fine mist spray for even application.

Dosing is 2 pumps per application, whatever the dog’s size, once a day for 7-14 days.
