HUNTER 22

DESCRIPTION

Fenbendazole is a broad spectrum benzimidazole anthelmintic used against gastrointestinal parasites including roundworms, hookworms, whipworms, the taenia species of tapeworms, pinworms, aerulostrongylus, paragonimiasis, strongyles and strongyloides.

In cattle and sheep, fenbendazole is active against Dictiocaulus viviparous and also against 4th stage larvae of Ostertagia spp. Fenbendazole also has an ovicide action.Fenbendazole acts by disrupting the the formation of microtubuli by binding to tubulin in the parasitic intestinal cells, preventing absorption of glucose. Fenbendazole is poorly absorbed after oral administration, reaching max after 20 hours in ruminants and more rapidly in monogastics. It is metabolized by the liver, and excreted within 48 hours in the faeces, and only 10% in the urine.
