The Introductction of Fenbendazole


Fenbendazole is an organic compound with the molecular formula C15H13N3O2S, which is a white or off-white powder, odorless and tasteless. It is soluble in dimethyl sulfoxide, slightly soluble in methanol, insoluble in water and dissolved in glacial acetic acid.


Fenbendazole is a broad-spectrum benzimidazole anthelmintic, effective against gastrointestinal parasites.
Fenbendazole has a strong structural affinity for the microtubule proteins of the worm, and by affecting cellular transport and energy metabolism, it serves to prevent the polymerization of microtubules, ultimately leading to disruption of worm cell integrity and energy transport functions. It has high anthelmintic activity not only against roundworms, hookworms, whipworms, some cestodes and roundworms, but also against some bronchial tree and lung parasites (catarrhal lungworms and pulmonary schistosomes).


Usage and dosage:
It is effective against gastrointestinal and respiratory nematodes in poultry. At 8mg/kg daily dose for 6 days, it is highly effective against chicken roundworms, capillary nematodes and tapeworms. It is effective against turkey roundworm at a dose of 350mg/kg, but if fed at 45mg/kg for 6 days, it will eliminate all the turkey roundworm, heterocyst nematodes and closed capillary nematodes. The best deworming regimen for pheasants, partridges, grouse, geese and ducks is 60mg/kg of feed for 6 days. For domestic pigeons naturally infected with closed capillary nematodes and pigeon roundworms, 100mg/kg mixed feed for 3-4 days, the efficiency is nearly 100%.
【Usage and dosage】 10-50mg per kg body weight of pigeon for one time internal use.
【Rest period】14 days for cattle and sheep, 3 days for pigs, 5 days for milk abandonment.


The Application & Function of Fenbendazole

Fenbendazole is a new broad-spectrum veterinary anthelmintic. It is suitable for removing adult and larvae of gastrointestinal nematodes in cattle, horses, pigs and sheep, with the advantages of broad anthelmintic spectrum, low toxicity, good tolerance, good palatability and wide safety range.


Fenbendazole anthelmintic. Broad-spectrum, high-efficiency, low-toxicity, anti-parasitic drug. It has a strong anthelmintic effect on parasites such as roundworms, nematodes, cestodes, cysts and liver fluke, and not only kills worms, but also has a great effect on migrating larvae which are harmful to liver, lung and intestine.


Fenbendazole is a benzimidazole anthelmintic, which not only has high anthelmintic activity against adult nematodes and larvae of gastrointestinal tract, but also has good effect on reticulonematodes, lamellipodia and cestodes, and has strong ovicidal effect.
