Pharmacological properties

АТСvet: QJ01 - antibacterials for systemic use. QJ01BA90 - Florfenicol.

Florfenicol is a synthetic broad-spectrum antibiotic, a thiamphenicol derivative. The antibiotic is effective against Pasteurella spp., Actinobacillus pleuropneumoniae, Bordetella bronchiseptica, Salmonella spp., Escherichia coli, Proteus spp., Haemophilus spp., Staphylococcus spp., Streptococcus spp., Shigella spp., Klebsiella spp., Enterobacter spp., Aeromonas salmonicida, Campylobacter spp., Edwardsiella ictaluri, Edwardsiella tarda, Flexibacter spp., Yersinia pseudotuberculosis, Vibrio spp., as well as mycoplasma (Mycoplasma spp.). The mechanism of action consists in inhibition of microbial cell peptidyl transferase enzyme activity, particularly – in the area of 70S ribosomes.

After oral administration, florfenicol is well absorbed (up to 90%) from digestive tract and distributed in organs and tissues, reaching concentrations of 4-8 μg/g in lungs, heart, pancreatic gland, skeletal muscles and spleen. Relatively high concentrations are present in bile, kidneys, small intestine and urine. Half-life of florfenicol makes 2.6-3.2 hours on average. It is primarily excreted renally unchanged through glomerular filtration, as well as in bile, being inactivated through formation of chelate compounds, then they are excreted in feces.
