Indications for use, specifying 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 cattle it is active against the following species:
Roundworms: Ostertagia, Haemonchus, Trichostrongylus, Nematodirus, Oesophagostomum, Bunostomum, Cooperia, and Strongyloides spp.
It is usually effective against inhibited larvae of Cooperia and Ostertagia,
Lungworms: Dictyocaulus viviparus,
Tapeworms: Moniezia spp.,
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), Chabertia and Oesophagostomum
It is usually effective against inhibited larvae of Ostertagia,
Lungworms: Dictyocaulus filaria,
Tapeworms: Moniezia spp.,
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
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 Albenil 2.5% 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.
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 (if any).
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 a different pharmacological class and having a different mode of action should be used.
Resistance to benzimidazoles (which includes albendazole) has been reported in Teladorsagia Haemonchus, Cooper and Trichostrongylus species in small ruminants in a number of countries, including the EU. Resistance to albendazole has been reported in Cooperia and Teladorsagia species 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.
Special precautions for use
(i) Special precautions for use in animals
Care must be taken not to damage the pharyngeal region when dosing, particularly in sheep. Do not administer other cobalt and selenium supplements concurrently with this product unless specifically advised by your veterinary surgeon.
Not to be diluted or mixed with other products.
Avoid the introduction of contamination during use.
Intensive use or misuse of anthelmintics can give rise to resistance. To reduce the risk, dosing programmes should be discussed with a veterinary surgeon.
The product should only be used in areas where deficiencies of selenium and cobalt are likely to occur. In cases of doubt, consult a veterinary surgeon.
(ii) Special precautions to be taken by the person administering the veterinary medicinal product to animals
Wash hands after use.
Avoid direct contact with the product.
Wear suitable 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 effected area with soap and water. If irritation persists, seek medical attention.
Adverse reactions
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.
Interactions
None known

Pharmacological particulars
Pharmacotherapeutic group: A broad spectrum multi-purpose anthelmintic
ATC vet 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 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. 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.
