5.1 Pharmacodynamic properties

Chlorbutol has anti-fungal and anti-bacterial properties. Phenoxyethanol is a bactericide particularly effective against Pseudomonas aeruginosa and can be used topically in the treatment of bacterial infections. The formulation represents complete solution of the 2 active ingredients in a non-aqueous base of propylene glycol with a pine perfume for consumer acceptability, which also helps to indicate which ear has been treated. Propylene glycol is commonly employed as the base in aural products and possesses anti-fungal and ear wax solvent properties. Clinical trials have demonstrated that Otodex Veterinary Ear Drops are effective in the treatment of the ear mite Otodectes cyonotis in the dog and cat although none of the components of Otodex Veterinary Ear Drops has recognised acaricidal activity.
