Pharmacokinetic model of florfenicol in turbot ( Scophthalmus maximus ): establishment of optimal dosage and administration in medicated feed
Abstract The pharmacokinetics of florfenicol ( FF ) in turbot ( Scophthalmus maximus ) was studied after single intravenous (10 mg kg −1 ) and oral (100 mg kg −1 ) administration. The plasma concentration–time data of florfenicol were described by an open one‐compartment model. The elimination half‐...

The apparent volume distribution ( V d ) was calculated to be 0.86 L kg −1 and the mean residence time ( MRT iv ) was 30.2 h. Following oral administration, the maximum plasma concentration ( C max ) of 55.4 μg mL −1 was reached at 12 h ( T max ). The absorption constant ( k a ) was 0.158 h −1 . The bioavailability was estimated to be 57.1%. The low bioavailability observed at higher doses was explained by the saturation of the mechanisms of absorption.
