Pharmacokinetics, Tissue Residues, and Withdrawal Times of Florfenicol in Chukar Partridges (Alectoris chukar).
The aim of this study was to determine pharmacokinetics of florfenicol and its metabolite florfenicol amine after a single (30 mg/kg) intravenous (IV) and oral administration of florfenicol in chukar partridges. It also aimed to investigate tissue residue and withdrawal time of florfenicol after multiple-dose (30 mg/kg, every 24 h for 5 days) oral administration. The research was carried out in two stages: pharmacokinetics and residue. Plasma and tissue concentrations of florfenicol and florfenicol amine were determined by HPLC. The elimination half-life of florfenicol was 5.25 h for IV and 5.44 h for oral. The volume of distribution at a steady state and total body clearance of florfenicol were 0.38 L/kg and 0.07 L/h/kg, respectively, after IV administration. The peak plasma concentration and bioavailability for oral administration were 45.26 ± 4.06 and 51.55%, respectively. After multiple-dose oral administration, the highest concentration was detected in the liver (9.21 μg/g) for florfenicol and in the kidney (0.67 μg/g) for florfeniol amine. The calculated withdrawal period of florfenicol was determined as 6, 3, 4, and 5 days for muscle, liver, kidney, and skin + fat, respectively. These data indicate that a 6-day WT after multiple-dose administration of florfenicol in chukar partridges can be considered safe for human consumption.
期刊介绍:
The Journal of Veterinary Pharmacology and Therapeutics (JVPT) is an international journal devoted to the publication of scientific papers in the basic and clinical aspects of veterinary pharmacology and toxicology, whether the study is in vitro, in vivo, ex vivo or in silico. The Journal is a forum for recent scientific information and developments in the discipline of veterinary pharmacology, including toxicology and therapeutics. Studies that are entirely in vitro will not be considered within the scope of JVPT unless the study has direct relevance to the use of the drug (including toxicants and feed additives) in veterinary species, or that it can be clearly demonstrated that a similar outcome would be expected in vivo. These studies should consider approved or widely used veterinary drugs and/or drugs with broad applicability to veterinary species.
