KINETIC DISPOSITION OF TRICLABENDAZOLE IN BUFFALO COMPARED TO CATTLE

Concentrations of triclabendazole sulfoxide and its sulfone metabolite in plasma were measured in buffalo and cross-bred cattle after single intraruminal administration of triclabendazole at two different doses . Plasma concentrations of both metabolites were significantly lower i n buffalo than cattle at both doses, which resulted in a smaller area under the concentration-time curve, a lower concentration maximum and a lower relative bioavailability, Thus, the recommended doses of 12 mg /kg body weight for the treatment of bubaline fascioliasis may not be valid for buffalo because of the substantially lower uptake of the dru g in this species.
