Pharmacokinetic characteristics of florfenicol in green sea turtles (Chelonia mydas) and hawksbill sea turtles (Eretmochelys imbricata) after intramuscular administration
The pharmacokinetics of florfenicol (FFC) in green sea and hawksbill sea turtles were evaluated following intramuscular (i.m.) administration at two different dosages of 20 or 30 mg/kg body weight (b.w.). This study (longitudinal design) used 5 green sea and 5 hawksbill sea turtles for the two dosages. Blood samples were collected at assigned times up to 168 h. FFC plasma samples were analyzed using validated high-performance liquid chromatography equipped with diode array detection. The pharmacokinetic analysis was performed using a non-compartment approach. The FFC plasma concentrations increased with the dosage. The elimination half-life was similar between the treatment groups (range 19–25 h), as well as the plasma protein binding (range 18.59%–20.65%). According to the surrogate PK/PD parameter (T > MIC, 2 μg/mL), the 20 and 30 mg/kg dosing rates should be effective doses for susceptible bacterial infections in green sea and hawksbill sea turtles.
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.
