【Veterinary drug name】

Product Name: Florfenicol powder

Chinese Pinyin: Fubennikao Fen

【Main ingredient】 Florfenicol

【Characters】This product is white or white-like powder.

【Pharmacological action】 

Pharmacodynamics Florfenicol is a broad spectrum antibiotic in the amidol class, a bacteriosuppressor, which acts by binding with the ribosome 50S subunit to inhibit the synthesis of bacterial proteins. It has strong antibacterial activity against a variety of gram-positive and Gram-negative bacteria. Pasteurella hemolyticus, Pasteurella multocida and actinobacillus pleuropneumoniae were highly sensitive to florfenicol. In vitro, the antimicrobial activity of florfenicol against many microorganisms is similar or stronger than that of sulfenicol, and some bacteria that are resistant to aminools due to acetylation, such as Escherichia coli and Klebsiella pneumoniae, may still be sensitive to florfenicol.

It is mainly used for the bacterial diseases of pigs, chickens and fish caused by sensitive bacteria, such as Pasteurella hemolyticus, Pasteurella multocida and actinobacillus pleuropneumoniae caused by bovine and pig respiratory diseases. Typhoid fever and paratyphoid fever caused by salmonella, chicken cholera, chicken white dysentery, escherichia coli, etc. Fish Pasteurella, Vibrio, staphylococcus aureus, hydroomonas, enteritis and other bacteria caused by fish bacterial septicemia, enteritis, erythroderma and so on.

Pharmacokinetics The absorption of florfenicol is rapid, and the therapeutic concentration can be reached in the blood after about 1 hour, and the peak blood concentration can be reached in 1 to 3 hours. The bioavailability is over 80%. Florfenicol is widely distributed in animals and can cross the blood-brain barrier. It is mainly excreted in the urine in its original form, and a small amount is excreted in the stool.
