Orbifloxacin is a synthetic fluoroquinolone antibacterial agent. The bactericidal action of fluoroquinolones is concentration-dependent and results from interference with bacterial DNA gyrase and topoisomerase IV. Since these enzymes are needed for bacterial DNA synthesis and transcription, fluoroquinolones disrupt bacterial replication and lead to bacterial cell death.


Mometasone furoate monohydrate is a topical corticosteroid characterized by a (2’) furoate 17-ester having chlorine at the 9 and 21 positions.


Posaconazole is a broad-spectrum triazole antifungal agent. The mechanism by which triazoles exert fungicidal action involves the selective inhibition of the enzyme lanosterol a C14 demethylase (a microsomal cytochrome P-450- dependent enzyme) involved in ergosterol biosynthesis in yeasts and filamentous fungi.

Systemic absorption of the active ingredients was determined in single-dose radiolabelled studies with14C-orbifloxacin, 3H-mometasone furoate, and 14C-posaconazole contained within the ear drops for dogs formulation and placed into the ear canals of normal beagle dogs. Most of the absorption occurred in the first few days of administration. The extent of percutaneous absorption of topical medications is influenced by many factors including the integrity of the epidermal barrier. Inflammation can increase the percutaneous absorption of drugs.


The effectiveness of dog ear cleaner was evaluated in a placebo-controlled, double-blind, multi-site field study. One hundred and ninety one dogs with naturally occurring clinical otitis externa in dogs associated with both yeast and bacteria were randomly allocated to either POSATEX™

Otic Suspension or placebo ointment. Of the 160 dogs evaluated for effectiveness, 122 were treated with POSATEX™ Otic Suspension and 38 were treated with placebo ointment. Treatments were administered once daily for 7 consecutive days. Assessment of effectiveness was based on improvement in clinical signs at re-evaluation 2-7 days following administration of the last dose.

Compared to the placebo, a significant percent of dogs treated with POSATEX™ Otic Suspension showed improvement in clinical signs (discomfort, erythema, and swelling) caused by otitis externa in dogs associated with one or more of the following organisms:

Malassezia pachydermatis, coagulase positive staphylococci, Pseudomonas aeruginosa, and Enterococcus faecalis.
