The present study was designed to investigate pharmacokinetics of levofloxacin following single dose intravenous and oral administration at the dose rate of 10 mg/kg of body weight and to evaluate safety after repeated administration (10 mg/kg) of levofloxacin at 12 hours interval for 14 days in layer birds. Drug concentration in serum was determined using High Performance Liquid Chromatography (HPLC). Following intravenous administration, the serum drug concentration-time curves were analyzed by non-compartmental approach.enVeterinary PharmacologyStudyThesis
