Excipients:

For the full list of excipients, see section 6.1

Tablet

Brown spiked, round flavoured tablets, quadrisect.

The tablets can be divided into equal halves and quarters.

Dogs

Treatment of dermatomycoses due to the following dermatophytes:

• Microsporum canis,

• Microsporum gypseum,

• Trichophyton mentagrophytes.

Do not administer to animals with liver failure.

Do not administer to animals with known hypersensitivity to the active substance or to any of the excipients.

Treatment with ketoconazole suppresses testosterone concentrations and increases progesterone concentrations and may affect breeding effectiveness in male dogs during and for some weeks after treatment.

Although rare, repeated use of ketoconazole may induce cross-resistance to other azoles.

Treatment of dermatophytosis should not be limited to treatment of the infected animal(s). It should also include disinfection of the environment, since spores can survive in the environment for long periods of time. Other measures such as frequent vacuuming, disinfection of grooming equipment and removal of all potentially contaminated material that cannot be disinfected will minimize the risk of re-infection or spread of infection.

Combination of systemic and topical treatment is recommended.

In case of long term treatment administration, liver function should be closely monitored. If clinical signs suggestive of liver dysfunction develop, treatment should be discontinued immediately.

People with known hypersensitivity to the active ingredients should avoid the contact of the skin and mucosae with the veterinary medicinal product.

In case of accidental ingestion, seek medical advice immediately and show the package leaflet or the label.

Wash hands after use.

Part (half/quarter) tablets should be stored in the original blister and be used for the next administration. Keep the blister in the outer carton to prevent access by children.

In rare cases, neurological symptoms (apathy, ataxia, tremors), hepatic toxicity, vomiting, anorexia and/or diarrhoea may be observed at standard doses.

Ketoconazole has anti-androgen and anti-glucocorticoid effects; it inhibits the conversion of cholesterol to steroid hormones such as testosterone and cortisolin a dose dependent and time-dependent manner. See also section 4.4 for effects in male breeding dogs.

Studies in laboratory animals have shown evidence of teratogenic and embryotoxic effects.

The safety of the product has not been established in pregnant or lactating bitches.

Use is not recommended during pregnancy.

Do not administer with antacids and/or H2-receptor antagonists (cimetidine/rantidine) or proton pump inhibitors (e.g. omeprazole) as the absorption of ketoconazole may be modified (absorption requires an acid environment).

Ketoconazole is a substrate and potent inhibitor of cytochrome P450 3A4 (CYP3A4). It may decrease the elimination of drugs metabolized by CYP3A4, thereby altering their plasma concentrations. Inducers of cytochrome P450 may increase the rate of metabolism of ketoconazole. Relevant veterinary interactions include cyclosporines, macrocyclic lactones (ivermectin, selamectin, milbemycin), midazolam, cisapride, amlodipine, fentanyl, macrolides (clarithromycin erythromycin), digoxin, anticoagulants and phenobarbital.

Ketoconazole inhibits the conversion of cholesterol to cortisol and may thus affect trilostane / mitotane dosing in dogs concurrently being treated for hyperadrenocorticism.

10 mg of ketoconazole per kg body weight daily, by oral administration. This corresponds to 1 tablet per 20 kg body weight daily.

It is recommended to sample the animal once a month during treatment and to stop antifungal administration after two negative cultures. When mycological follow up is not possible, treatment should be continued for an adequate period of time to ensure mycological cure.If lesions persist after 8 weeks of treatment, medication should be re-evaluated by the responsible veterinarian.

To be administered preferably together with food, in order to maximise absorption.

Tablets can be divided into equal halves or quarters to ensure accurate dosing. Put the tablet on a flat surface, with its scored side facing up and the convex (rounded) side facing the surface.

Equal Halves: With the tip of the thumbs, exert a slight vertical pressure on both sides of the tablet to break it into halves.

Equal quarters: With the tip of a thumb, exert a slight vertical pressure on the middle of the tablet to break it into quarters.

In cases of overdose the following effects may be seen: anorexia, vomiting, pruritus, alopecia and increase of hepatic alanine aminotransferase (ALT) and alkaline phosphatase (ALP).

Not applicable.

Pharmacotherapeutic group:Systemic antimycotics, imidazole derivatives.

ATCVet code:QJ02AB02

Ketoconazole is an antifungal agent with a wide spectrum, derived from imidazole-dioxolane, which exerts a fungistatic and sporicidal effect on dermatophytes in dogs.

Ketoconazole widely inhibits the cytochrome P450 system. Ketoconazole modifies the permeability of membranes of fungi, and inhibit specifically the synthesis of ergosterole, which is an essential component of the cellular membrane of fungi, principally by inhibiting the enzyme cytochrome P450 14-alpha-demethylase (P45014DM).

Ketoconazole has anti-androgen and anti-glucocorticoid effects; it inhibits the conversion of cholesterol to steroid hormones such as testosterone and cortisol. It produces this effect through inhibition of cytochrome P450 enzymes involved in the synthesis.

Through inhibition of CYP3A4, metabolism of many drugs is decreased and their in-vivobioavailability increased.

Ketoconazole inhibits p-glycoprotein efflux pumps and may increase the oral absorption and tissue distribution of other medicines, e.g. prednisolone.

After oral administration, peak plasma levels of 22 – 49 µg/ml (mean 35 µg/ml) are obtained within 1.5 to 4.0 hours (mean 2.9 hours).

Ketoconazole is bound to the albumin fraction of plasma proteins. Ketoconazole is metabolised by the liver into several inactive metabolites. It is excreted predominantly into bile and to a lesser extent into urine. The terminal elimination half-life ranged between 3 and 9 hours (mean 4.6 hours).
