Chemical composition and pharmacological properties

1 ml of Florfenicol 40% contains florfenicol - 400 mg as an active ingredient; as well as benzyl alcohol, methylpyrrolidone as excipients.

Appearance: transparent colorless to greenish-yellow liquid.

Florfenicol 40% belongs to the amphenicols pharmacotherapeutic group. Florfenicol is a derivative of thiamphenicol, in the molecule of which the hydroxyl group is replaced by a fluorine atom, has a bacteriostatic effect against Actinobacillus pleuropneumoniae, Pasteurelia spp., Salmonella choleraesuis, Bordetella bronchiseptica, Haemophilus spp., Staphylococcus s pp., Streptococcus spp., Klebciella pneumoniae, Moraxella bovis, including bacteria that produce acetyltransferase and are resistant to chloramphenicol as well as mycoplasmas M. hyopneumoniae and M. hyorhinis.

After binding to the 50S ribosomal subunit in the protoplasm of a bacterial cell, it blocks the enzyme peptidyltransferase, which leads to inhibition of protein synthesis in sensitive microorganisms at the ribosomal level.

After parenteral administration, florfenicol is rapidly absorbed from the injection site and is distributed into most organs and tissues. Bacteriostatic blood concentrations of florfenicol after a single intramuscular injection persist for at least 48 hours, and at least 100 hours after subcutaneous administration.

Antibiotic is excreted in unchanged form and in the form of metabolites mainly with urine, and, to a lesser extent, with feces.

According to the extent of exposure, Florfenicol 40% belongs to the group of moderately hazardous substances (hazard class 3 according to GOST 12.1.007).

Dosage and administration

Florfenicol 40% is used:

– cattle – at a dose of 1 ml per 20 kg of animal weight intramuscularly twice with an interval of 48 hours, or at a dose of 2 ml per 20 kg of animal weight subcutaneously once;

– pigs – at a dose of 1 ml per 30 kg of animal weight intramuscularly twice with an interval of 48 hours.

The maximum volume for the administration of the drug in one place should not exceed 20 ml for cattle, 5-10 ml for small animals. If the volume of the injected drug is more than specified, it should be administered to animals in several places.

In some animals, a local reaction in the form of edema may occur at the injection site. With increased individual sensitivity of the animal to the components of the drug and the appearance of allergic reactions, the use of the drug is discontinued and symptomatic treatment is carried out.
