Molecular Formula: C15H13N3O2S
Melting point: 233℃
Fenbendazole is a white or off-white, crystalline powder, it is odorless and tasteless, and it is insoluble in water but soluble in glacial acetic acid and easy soluble in dimethyl sulfoxide, slightly soluble in methanol, low toxicity, ral LD50 in rats is above 10,000 mg / kg.
1.Sheep: Adults and larvae of Haemachus nematodes, Oerste nematodes, Trichostrongylus sp Be efficient. It has a good repellent effect on Monitzia spp. Large doses are required for flukes, such as 20 mg / kg for 5 days, and the effective rate for Spear-shaped double-lumen trematodes is 100%; 15 mg / kg for 6 days is effective for liver flukes.
2.Cattle: The deworming spectrum of cattle is roughly similar to that of sheep. Higher doses of trematodes are needed, such as 7.5 to 10 mg / kg for 6 days. It has a good effect on adult trematodes and trematodes of cattle.
3.Horses: Fenbendazole has excellent effects on horsetail parasites, adult and larvae of horsetail nematodes, viviparous worms, common round nematodes, toothless roundworms, horse roundworms, and small roundworms.
4.Pigs: Fenbendazole has a good insect repellent effect on adult and larvae of Ascaris suum, red roundworm, esophageal mouth nematode. It was also used for 3 days at 3mg / kg, which also had a significant killing effect on C. elegans.
5.Dogs and cats: The oral administration of 25mg / kg in dogs has obvious effects on hookworms, hairworms, and roundworms. 50mg / kg can be used for 14 days to kill the larvae of Ascaris canis during the transition period; it can almost drive out ascaris for 3 days. Cats are treated for 3 days and are effective against cats, hookworms, and roundworms.
6.Wild Animals: For deer infected with Oerste nematodes, Coopers nematodes, N. elegans, Trichostrongylus, hairy head nematodes, and pulmonary filariasis, oral administration of 5 mg / kg for 3 to 5 days is possible. In addition, it is also certain for Monitzia effect. For various carnivorous raptors that are severely infected with avian tapeworms, sawtooth nematodes, capillary nematodes, and flukes, 25 mg / kg for 3 consecutive days.
1.Fenbendazole has a high anthelmintic activity against gastrointestinal nematodes and larvae.
2.Fenbendazole has a strong repellent effect on roundworms, nematodes, roundworms, cysticercosis, and liver flukes
3.Fenbendazole can against gastrointestinal worms, larvae, networms, flukes, tapeworms and eggs.
