CLINICAL PARTICULARS
Target Species
Cattle, Sheep
Indications for use, specifying the target species
A broad spectrum multi-purpose anthelmintic for the control of mature and developing immature forms of gastrointestinal roundworms, lungworms, tapeworms and adult liver fluke in cattle and sheep. The product is also ovicidal against fluke and roundworm eggs.
In cattleit is active against the following species:
Roundworms: Teladorsagia (Ostertagia), Haemonchus, Trichostrongylus, Nematodirus, Oesophagostomum, Bunostomum, Cooperia, and Strongyloidesspp.
It is usually effective against inhibited larvae of Cooperiaand Ostertagia,
Lungworms: Dictyocaulus viviparus,
Tapeworms: Monieziaspp.,
Adult liver fluke: Fasciola hepatica.
In sheep it is active against benzimidazole-susceptible strains of the following species:
Roundworms: Ostertagia, Haemonchus, Trichostrongylus, Nematodirus (including N. battus), Chabertiaand Oesophagostomum
It is usually effective against inhibited larvae of Ostertagia,
Lungworms: Dictyocaulus filaria,
Tapeworms: Monieziaspp.,
Adult liver fluke: Fasciola hepatica.
The product is ovicidal and will kill fluke and roundworm eggs, thus reducing pasture contamination.
The product also contains selenium and cobalt as nutritional supplements.
Contra-indications
Known hypersensitivity to the active ingredient.
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 bodyweight.
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 (which includes albendazole) has been reported in Teladorsagia, Haemonchus, Cooperia and Trichostrongylusspecies in small ruminants in a number of countries including the EU. Resistance to albendazole has been reported in Cooperiaand Teladorsagiaspecies in cattle in developed countries such as New Zealand. Therefore the use of this product should be based on local (regional, farm) epidemiological information about susceptibility of nematodes and recommendations on how to limit further selection for resistance to anthelmintics.
Selenium and cobalt are included as nutritional supplements and are not intended to be used therapeutically. Administration of ionophores to lambs has been shown to enhance selenium bioavailability. Concurrent administration of ionophores and Benzimole 25 mg/ml SC may therefore lead to an increased risk of selenium toxicity.
Cattle suffering from severe lung damage due to heavy lungworm infestation may continue to cough for some weeks after treatment.
Special precautions for use
Special precautions for use in animals
Do not administer other cobalt and selenium supplements concurrently unless advised by you veterinary surgeon. Not to be diluted
Special precautions for the person administering the veterinary medicinal product to animals
Direct contact with the skin should be kept to a minimum. Wear suitable protective clothing including impermeable rubber gloves. In the event of accidental eye exposure, flush eye thoroughly with running water. If irritation persists, seek medical attention. In the event of accidental skin exposure, wash the affected area with soap and water. If irritation persists, seek medical attention. Wash hands after use.
Adverse reactions (frequency and seriousness)
None known.
Use during pregnancy, lactation or lay
Do not dose ewes at the 'fluke and worm' dose rate, (7.5 mg/kg), during tupping or for 1 month after removing the rams. Can be safely used during lactation. The use of the product in breeding bulls or pregnant cattle is not expected to interfere with their reproductive performance.
Interaction with other medicinal products and other forms of interaction
None known.
Amounts to be administered and administration route
To ensure administration of a correct dose, body weight should be determined as accurately as possible; accuracy of the dosing device should be checked
For oral administration.

PHARMACOLOGICAL PROPERTIES
Pharmacodynamic properties
ATCVet Code: QP52AC11
A broad spectrum multi-purpose anthelmintic for the control of mature and developing immature forms of gastrointestinal roundworms, lungworms, tapeworms and adult liver fluke in cattle and sheep. The product is also ovicidal against fluke and roundworm eggs.
Benzimidazoles have also been shown to inhibit the fumarate reductase system of helminths and impair energy production.
The selenium and cobalt in this product are trace elements of use as nutritional supplements.
Pharmacokinetic particulars
Benzimidazoles bind to nematode tubulin, a protein necessary for the formation and viability of microtubules. This occurs primarily in absorptive intestinal cells resulting in the absence of microtubules in the intestinal cells of the nematode, with the result that these cells cannot absorb nutrients, thus causing a consequent reduction in glycogen and effective starvation of the parasites. Structural differences have been shown to exist between tubulin from mammalian and helminth sources, resulting in the preferential toxicity of albendazole to the helminth and not to the host.
