Abstract

The study was carried out to determine the biodisposition kinetics of ciprofloxacin in sheep model in Department of Pharmacology, Bangladesh Agricultural University. Healthy sheep of both sexes (n=65) were divided into 13 groups, each consists of five and given a single dose of ciprofloxacin @ 5 mg/kg bwt intramuscularly .Blood sample was collected from each group of sheep at 0, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 6, 8, 10 and 12 hours interval respectively. Serum concentration of ciprofloxacin was determined by spectrophotometric method. The pharmacokinetic parameters were measured by single compartment open model and first order kinetics. The peak concentration of ciprofloxacin was 3.56±0.15mg/ ml, absorption half-life and biological half-life were 0.0846±1.79 and 1.75±0.15 h respectively. The apparent volume of distribution was found 35.54 mg/liter. The absorption rate constant was 8.188h-1, MRT was 2.647h-1 and total body clearances were found 16.88 h-1. These result suggested that a dose of 5 mg/kg bwt provides maximum plasma concentration and is effective in the control of many infectious diseases of sheep.

Key words: Plasma pharmacokinetics, ciprofloxacin, sheep
