METHODS: Sixty-five quail were given an I/V and I/M dose of florfenicol at 30 mg/kg bodyweight (BW). A two-period sequential design was used, with a wash-out period of 2 weeks between the different routes of administration. Concentrations of florfenicol in plasma were determined using high-performance liquid chromatography (HPLC). RESULTS: A naive pooled data analysis approach for the plasma concentration-time profile of florfenicol was found to fit a non-compartmental open model. After I/V administration, the mean residence time (MRT), mean volume of distribution at steady state (V(ss)), and total body clearance of florfenicol were 12.0 (SD 0.37) h, 8.7 (SD 0.22) L/kg, and 1.3 (SD 0.08) L/h/kg, respectively. After I/M injection, the MRT, mean absorption time (MAT), and bioavailability were 12.3 (SD 0.37) h, 0.2 (SD 0.02) h, and 79.1 (SD 1.79)%, respectively. CONCLUSIONS: The time for the concentration of florfenicol to fall below the probable effective concentration of 1 mu g/ml of approximately 10 h is sufficient for the minimum inhibitory concentration needed for many bacterial isolates. Further pharmacodynamic studies in quail are needed to evaluate a suitable dosage regimen.en10.1080/00480169.2009.64734info:eu-repo/semantics/closedAccessPharmacokineticflorfenicolquailplasmabioavailabilityArticle57638839119966901Q1WOS:000273349900014Q2
