4.1 Target Species

Horses and cattle

4.2 Indications for use, specifying the target species
For the treatment of immature and mature stages of nematodes of the gastro-intestinal and respiratory tracts of cattle and horses including encysted mucosal small redworm larvae in horses.
Panacur has an ovicidal effect on roundworm eggs.
Also effective against cestodes in cattle.
For the treatment of horses infected with adult large strongyles and adult and larval small strongyles.

Strongyloides spp.,
Oesophagostomum spp.,

4.3 Contraindications
Do not use in cases of hypersensitivity to the active substance or to any of the excipients.

4.4 Special warnings for each target species
Care should be taken to avoid the following practices because they increase the risk of development of resistance and could ultimately result in ineffective therapy:
• Too frequent and repeated use of anthelmintics from the same class, over an extended period of time.
• Underdosing, which may be due to underestimation of body weight, misadministration of the product, or lack of calibration of the dosing device.
Suspected clinical cases of resistance to anthelmintics should be further investigated using appropriate tests (e.g. Faecal Egg Count Reduction Test).
Where the results of the test(s) strongly suggest resistance to a particular anthelmintic, an anthelmintic belonging to another pharmacological class and having a different mode of action should be used.
Resistance to benzimidazoles has been reported in gastro-intestinal nematodes in horses.
Therefore, the use of this product should be based on local epidemiological information about susceptibility of the nematodes and recommendations on how to limit further selection for resistance to anthelmintics.

4.5 Special precautions for use
Special precaution(s) for use in animals

As with other anthelmintics, veterinary advice should be sought on appropriate dosing programmes and stock management to achieve adequate parasite control and reduce the likelihood of anthelmintic resistance developing.

Wear suitable protective clothing including impermeable rubber gloves.
Wash hands after use.

Pharmacotherapeutic group:

Benzimidazoles and related substances

ATCvet code:

5.1 Pharmacodynamic properties
Fenbendazole is an anthelmintic belonging to the benzimidazole-carbamate group.
It acts by interfering with the energy metabolism of the nematode.
The anthelmintic affects both adult and immature stages of gastro-intestinal and respiratory nematodes.
This anthelmintic efficacy is based on inhibition of the polymerisation of tubulin to microtubuli.

5.2 Pharmacokinetic properties
Fenbendazole is only partly absorbed after oral administration and is then metabolised in the liver.
The half-life of fenbendazole in serum after oral application of the recommended dose is
10-18 hours in cattle,
21-33 hours in sheep and
     10 hours in pigs.

Fenbendazole and its metabolites are distributed throughout the body but highest concentrations are found in the liver.
The elimination of fenbendazole and its metabolites occurs primarily via the faeces (>90%) and to a smaller extent as well in the urine and milk.
Fenbendazole is metabolised to its sulfoxide, then to sulfone and amines.
