HIDE SMILES / InChI
Rafoxanide is a halogenated salicylanilide used as a fasciolicide in cattle, sheep, goats, and horses. It is also active against nematodes, and the sheep nasal bot fly. Rafoxanide acts as by uncoupling oxidative phosphorylation of flukes, including reduced ATP levels, decreased glycogen content and accumulation of succinate.

Sample Use Guides

The recommended dose range from 5 to 15 mg/kg bw is generally administered by oral gavage or by intra-ruminal route.
Route of Administration: Oral
In Vitro Use Guide
Flukes recovered from infected sheep were maintained in laboratory conditions in warm (37 deg-C) Hedon-Fleig saline and used within one hour of recovery. Rafoxanide tested in a concentration range of 0.01 to 1000 micro-g/mL as the commercial solutions, and in ethanol, dimethyl sulphoxide and Tween 80. Rafoxanide demonstrated faciolicide activity and a dose-response relationship. The motility of Fasciola hepatica was monitored by means of an isometric transducer connected to a high-speed pen recorder
