What are the active ingredients in Surolan?


Miconazole nitrate is a synthetic imidazole derivative with a pronounced antifungal activity and a potent activity against Gram-positive bacteria. Miconazole selectively inhibits the synthesis of ergosterol, which is an essential component of the membrane of yeasts and fungi.

Polymyxin B sulfate is a polypeptide antibiotic with bactericidal activity against Gram-negative bacteria. It binds to phospholipids in the cytoplasmic membrane, whereby the membrane permeability is disturbed. This results in lysis of the bacteria.

Prednisolone acetate is a glucocorticoid with strong anti-inflammatory activity which results from its reduction of the permeability of capillaries and vascular proliferation and from the inhibition of fibroblast action.

After topical application of miconazole nitrate, virtually no systemic absorption takes place through the skin or mucus membranes.

Systemic absorption of prednisolone on normal or abraded skin is minimal. Absorption of polymyxin B via the skin is also negligible. Excretion is almost completely via the kidneys.

Is there any further advice I should know about Surolan?



Do not use in animals with perforated ear drums since Polymyxin B is known to be a potential ototoxic agent.


Special warnings for each target species


As the product is a prescription only medicine, treatment should be closely supervised by a veterinary practitioner.


Special precautions for use in animals


For external use only.

Due to likely variability (time, geographical) in the occurrence of resistance of bacteria for Polymyxin B, bacteriological sampling and susceptibility testing are recommended.


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


Do not handle the product if you are allergic to the ingredients in the product.

Accidental spillage on the skin should be washed off immediately with soap and water. Wash hands after use.

Corticosteroids may produce irreversible effects in the skin. They can be absorbed and may have harmful effects, especially with frequent and extensive contact or in pregnancy. Always wear single use disposable gloves when applying the product to animals.


Adverse reactions


Long-term use of topical steroids may cause skin thinning and delay wound healing.


Use during pregnancy and lactation


Corticosteroids are not recommended for use in pregnant animals.


Overdose (symptoms, emergency procedures, antidotes), if necessary


The product is applied topically. No toxic side effects have been observed after accidental intake by licking.
