Pharmacodynamics:  Florfenicol is a kind of amphenicol broad-spectrum antibiotics which acts as a bactericide through binding with 50s ribosomal subunit and inhibit protein synthesis. Florfenicol is effective against many Gram positive and negative bacteria. It is also highly sensitive to Pasteurella hemolytica, Pasteurella multocida, and Actinobacillus pleuropneumoniae. Florfenicol’s mechanism is similar to thiamphenicol but stronger. Due to some acetylated modification, some bacteria with drug resistance such as E. coli and Klebsiella pneumoniae may still be sensitive to florfenicol. 

Florfenicol is mainly used on porcine, broilers, and fish bacterial infections such as Pasteurella hemolytica, Pasteurella multocida, and Actinobacillus pleuropneumoniae in bovine and porcine circulatory system. Salmonella spp. can cause typhoid fever, paratyphoid fever, chicken cholera, pullorum disease, and E. coli infection. Fish diseases by Pasteurella, Virbio, Staphylococcus, Aeromonas hydrophila, Enteritis bacteria can cause fish bacterial hemorrhagic septicemia, enteritis, and erythrodermatitis.

Within an hour, the concentration can be of treatment and in one to three hours at its highest peak of concentration with 80% utilization. Florfenicol disperses widely inside animal body and through the circulatory system and mainly dispose by urine with little by feces.
