Abstract

Pharmacokinetics of oxfendazole and its sulfone metabolite were determined in 6 sheep. Oxfendazole achieved mean peak plasma concentrations of 0.76 micrograms/ml at 30 hours after oral administration of oxfendazole (10 mg/kg of body weight), and concentrations were detectable for up to 7 days after administration. Mean peak abomasal concentrations of 3.55 micrograms/ml occurred 20 hours after administration and were detectable up to 9 days after administration. Concentrations of sulfone in plasma and abomasal fluid were generally lower than were those of oxfendazole.
