چکیده

The comparative pharmacokinetic profile of cefquinome was studied in sheep and goats following repeated intramuscular (IM) administrations of 2 mg/kg body weight. Cefquinome concentrations in serum were determined by microbiological assay technique using Micrococcus luteus (ATCC 9341) as test organism. Following intramuscular injection of cefquinome in sheep and goats, the disposition curves were best described by two-compartment open model in both sheep and goats. The pharmacokinetics of cefquinome did not differ significantly between sheep and goats; similar intramuscular dose rate of cefquinome should therefore be applicable to both species. On comparing the data of serum levels of repeated intramuscular injections with first intramuscular injection, it was revealed that repeated intramuscular injections of cefquinome have cumulative effect in both species sheep and goats. The in vitro serum protein-binding tendency was 15.65% in sheep and 14.42% in goats. The serum concentrations of cefquinome along 24 h after injection in this study were exceeding the MICs of different susceptible microorganisms responsible for serious disease problems. These findings indicate successful use of cefquinome in sheep and goats.

Influence of the injection site on the pharmacokinetics of cefquinome following intramuscular injection in piglets.

The aim of the present study was to investigate the influence of different injection sites, i.e., the neck area and thigh muscle, on the pharmacokinetics of cefquinome in piglets following intramuscular (i.m.) injection. Cross-bred (Landrace × Duroc × Yorkshire) piglets were administered the same dose of cefquinome (2 mg/kg body weight) via intravenous injection and intramuscular injection into...

Pharmacokinetics, dosage regimen and in vitro plasma protein binding of intramuscular levofloxacin in buffalo calves

The pharmacokinetics of levofloxacin following its single intramuscular administration (3 mg/kg) was investigated in six male buffalo calves. Peak plasma level of 2.95 ± 0.13μg/ml was observed at 1 h and the drug level above MIC90  in plasma was detected up to 12 h of administration. The bioavailability was 68.1 ± 5.4% and levofloxacin was bound to the plasma proteins to the extent of 19.1 ± 1....
