What is Aurizon and who is it for?


Aurizon is an oily suspension for aural use, for the treatment of otitis externa of both bacterial and fungal origin – respectively due to bacteria sensitive to marbofloxacin, and fungi sensitive to clotrimazole. Use of the product should be based on susceptibility testing.


This is a Prescription only medicine (POM-V).

Aurizon is only available with a prescription from your veterinary surgeon.

To check the most up to date information about this product, please read its Summary of Product Characteristics (SPC). It can be viewed here.

What are the active ingredients in Aurizon?


Marbofloxacin: a synthetic anti-infectious bactericidal agent belonging to the fluoroquinolone family that acts by inhibiting DNA gyrase. It exhibits a very broad spectrum of activity against Gram-positive bacteria (in particular Staphylococcus intermedius) and against Gram-negative organisms (Pseudomonas aeruginosa, Escherichia Coli and Proteus mirabilis).

Clotrimazole: an anti-fungal agent that belongs to the imidazole family and which acts by causing changes in membrane permeability, allowing intracellular compounds to leak from the cell and thus inhibiting cellular molecular synthesis. It exhibits a wide spectrum of activity and is aimed, in particular at Malassezia pachydermatis.

Dexamethasone acetate: a synthetic glucocorticoid exhibiting anti-inflammatory and anti-pruritic activity.


Aurizon does not contain an antimicrobial preservative.

Is there any further advice I should know about Aurizon?



Do not administer to dogs suffering from perforation of the tympanic membrane.

Do not administer to dogs with known sensitivity to any of the ingredients.

Do not administer to pregnant or lactating bitches.

Usual adverse reactions associated with corticosteroid drugs may be observed (changes in biochemical and haematological parameters, such as increase of alkaline phosphatase and of aminotransferase, some limited neutrophilia)

Prolonged and intensive use of topical corticosteroid preparations is known to trigger local systemic effects, including suppression of adrenal function, thinning of the epidermis and delayed wound healing.

On rare occasions, the use of this product may be associated with deafness, mainly in elderly dogs and mostly of a transient nature.

Heavy reliance on a single class of antibiotic may result in the introduction of resistance in a bacterial population. It is prudent to reserve fluoroquinolones for the treatment of clinical conditions which have responded poorly, or are expected to respond poorly to other classes of antibiotics.

Before treating with the product, the integrity of the tympanic membrane must be verified.

The external ear canal should be meticulously cleaned and dried before treatment.

Changes in biochemical and heamatological parameters (such as increase of alkaline phosphatase), aminotransferase, some limited neutophilia, eosinopenia, lymphopenia) are observed with three fold the recommended dosage: such changes are not serious and will reverse once treatment has stopped.


Special precautions to be taken by the person administering the product to animals


Wash hands carefully after applying product. Avoid contact with eyes. If the product splashed the eye accidentally, rinse with copious amounts of water.

Persons with known hypersensitivity to compounds in the product should avoid any contact with the product.
