Properties The main pharmacological action of the active ingredient in nitroxinil is fasciolicidal. The lethal action against Fasciola hepatica has been demonstrated in vitro and in vivo in laboratory animals, and in sheep and cattle. The mechanism of action is due to uncoupling of oxidative phosphorylation. It is also active against triclabendazole-resistant F. hepatica.
It is indicated for the treatment of fascioliasis (infestations of mature and immature Fasciola hepatica) in cattle and sheep. It is also effective, at the recommended dose rate, against adult and larval infestations of Haemonchus contortus in cattle and sheep and Haemonchus placei, Oesophagostomum radiatum and Bunostomum phlebotomum in cattle.
