Pharmacology
Pharmacodynamics
Florfenicol is a broad-spectrum antibiotic of amide alcohols and is a bacteriostatic agent. It acts by binding to the 50 S subunit of the ribosome to inhibit bacterial protein synthesis. It has strong antibacterial activity against a variety of Gram-positive bacteria and Gram-negative bacteria. Pasteurella hemolyticus, Pasteurella multocida and Actinobacillus pleuropneumoniae are highly sensitive to florfenicol. The antibacterial activity of florfenicol against many microorganisms in vitro is similar to or stronger than that of thiamphenicol. Some bacteria resistant to amide alcohols due to acetylation, such as Escherichia coli and Klebsiella pneumoniae, may still be resistant to fluorobenzene Nico is sensitive. It is mainly used for the bacterial diseases of pigs, chickens and fish caused by sensitive bacteria, such as the respiratory diseases of cattle and pigs caused by Pasteurella hemolyticus, Pasteurella multocida and Actinobacillus pleuropneumoniae. Salmonella caused by typhoid fever and paratyphoid fever, chicken cholera, chicken pullorum, colibacillosis, etc.; fish bacterial sepsis caused by fish pasteurella, vibrio, Staphylococcus aureus, hydrophila, enteritis, etc. Enteritis, red skin disease, etc.
Pharmacokinetics
Florfenicol is absorbed rapidly by oral administration, and the therapeutic concentration can be reached in the blood after about 1 hour, and the peak blood concentration can be reached within 1 to 3 hours. The bioavailability is over 80%. Florfenicol is widely distributed in animals and can penetrate the blood-brain barrier. It is mainly excreted in urine in its original form, and a small amount is excreted in feces.
Medicine interactions
1. Macrolides and lincosamides have the same target of action as this product, both of which are combined with the 50 S subunit of the bacterial ribosome, and can produce mutual antagonism when used in combination.
2. It may antagonize the bactericidal activity of penicillin or aminoglycoside drugs, but it has not been proven in animals.
Function and Use
Amido alcohol antibiotics. Used for bacterial diseases caused by Pasteurella and Escherichia coli.
