4 CLINICAL PARTICULARS
4.1 Target Species Cattle and sheep
4.2 Indications for use, specifying the target species
Albex 2.5% is 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 Tapeworm: 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
Albex 2.5% is ovicidal and will kill fluke and roundworm eggs, thus reducing pasture contamination.
4.3 Contraindications
Do not use in cases of known hypersensitivity to the active ingredient.
4.4 Special warnings for each target species
Not for use in sheep producing milk for human consumption.
Cattle suffering from severe lung damage due to heavy lungworm infestation may continue to cough for some weeks after infection. Intensive use or misuse of anthelmitics can give rise to resistance. To reduce this risk, dosing programmes should be discussed with your veterinary surgeon. Care must be taken not to damage the pharyngeal region when dosing, particularly in sheep.
4.5 Special precautions for use
Special precautions for use in animals
Not to be diluted or mixed with other products.
Avoid the introduction of contamination during use.

Direct contact with the skin should be kept to a minimum. Wear suitable protective clothing including impermeable rubber gloves. Wash hands after use.
4.6 Adverse reactions (frequency and seriousness)
None known.
4.7 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.

5 PHARMACOLOGICAL or IMMUNOLOGICAL PROPERTIES
Albex 2.5% is 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.
