Cronus Pharma has officially launched Florfinasone Otic, a new medication formulated to treat otitis externa in dogs. The product, which is approved for use specifically in canines, is now available to veterinary providers across the United States.
Why it matters
Otitis externa is a common and painful condition for dogs that often requires precise medication to address underlying yeast and bacterial components. This new option provides veterinarians with an additional tool to manage these infections using a combination of active ingredients.
The medication is approved under ANADA #200-848 and contains 16.6 mg/mL florfenicol, 14.8 mg/mL terbinafine, and 2.2 mg/mL mometasone furoate. It is distributed in cartons containing ten single-use 1mL dropperettes.

The details
Florfinasone Otic targets canine otitis externa by addressing susceptible Malassezia pachydermatis yeast and Staphylococcus pseudintermedius bacteria.

The Home Front
This release follows the standard regulatory path established by the FDA's Abbreviated New Animal Drug Application (ANADA) process, which streamlines the approval of generic animal medications. The expansion of such treatments reflects a broader industry trend toward providing more targeted pharmaceutical options for common household pet health issues.
If your dog is showing signs of ear discomfort, consult your veterinarian to determine if this new medication is appropriate for their specific diagnosis. Never use medication intended for other animals or human use on your dog, as this product is strictly formulated for canine ear health.
The takeaway
Effective management of canine ear infections requires professional diagnosis and the use of approved, targeted therapies. Discuss specific treatment options with your vet to ensure your dog receives the correct dosage and formulation for their condition.
