Oxyclozanide is a salicylanilide anthelmintic, used for the treatment and control of fascioliasis in cattle, sheep, and goats. The mechanism of action of oxyclozanide is the uncoupling of oxidative phosphorylation in flukes. It is formulated as an oral drench containing oxyclozanide only or in combination with levamisole hydrochloride or oxfendazole or as a powder to be incorporated in the feed. The recommended doses are 10 to 15 mg oxyclozanide/kg BW for cattle and 15 mg oxyclozanide/kg BW for sheep and goats. The application was amended to exclude sheep milk and goat tissues and milk.

In Vitro Use Guide

Oxyclozanide (5 mg/ml stock solution in DMSO) were tested by broth microdilution and disc diffusion assays in triplicate, adapted from established protocol. Broth microdilution was performed in triplicate in 96-well plates using Müller-Hinton broth (Becton Dickinson and Company, Franklin Lakes, NJ, USA). For testing MIC with daptomycin, the media was supplemented with CaCl2 at a final concentration of 50 μg/ml. The assay volume was 100 μl and twofold serial dilutions were carried out to get Oxyclozanide in the concentration range 0.0625–64 μg/ml. The bacterial concentration was adjusted to an initial OD600 of 0.03. After overnight incubation at 35°C, the absorbance was measured to determine antimicrobial activity. The minimum bactericidal concentration (MBC) was determined by plating 10 μl of culture volume from the MIC assay on Müller-Hinton agar and colony formation was examined after overnight incubation at 35°C. The lowest concentration at which colonies were not observed was regarded as the MBC.
