Strongyles, horse

Phenothia2ine [58-37-7] (thiodiphenylamine) is used orally against intestinal nematodes of mminants and horses. It is used with occasional gastrointestinal upset, hemolytic processes, and photosensitivity. It is used routinely at low concentrations on horse farms to suppress the egg production of intestinal parasites (strongyles) and thus limit pasture contamination and transmission (4).

In horses, piperazine eliminates adult worms of small strongyles and P. equorutnin in more than 90% of the animals, but is less effective against S. vulgaris, S. edentatus and O.equi. The recommended dose of the drug is 90 mg (base)/kg administered orally as citrate, phosphate or adipate salts.
