Ceftiofur[edit]

Ceftiofur is a cephalosporin antibiotic used in veterinary medicine. It is a third-generation cephalosporin that is effective against a broad spectrum of Gram-positive and Gram-negative bacteria. Ceftiofur is commonly used to treat respiratory infections in cattle, swine, and horses.

Mechanism of Action[edit]

Ceftiofur works by inhibiting bacterial cell wall synthesis. It binds to penicillin-binding proteins (PBPs) located inside the bacterial cell wall, which are essential for the cross-linking of the peptidoglycan layer. This inhibition leads to the weakening of the cell wall and eventually causes bacterial cell lysis and death.

Pharmacokinetics[edit]

Ceftiofur is administered via intramuscular or subcutaneous routes. After administration, it is rapidly absorbed into the bloodstream and distributed throughout the body. Ceftiofur is metabolized in the liver to desfuroylceftiofur, which retains antibacterial activity. The drug and its metabolites are primarily excreted in the urine.

Clinical Uses[edit]

Ceftiofur is used to treat a variety of bacterial infections in animals, including:

Bovine respiratory disease (BRD) in cattle
Swine respiratory disease (SRD) in pigs
Equine respiratory infections in horses

It is also used to treat foot rot and acute metritis in cattle.

Safety and Side Effects[edit]

Ceftiofur is generally well-tolerated in animals. However, some animals may experience mild side effects such as swelling at the injection site, diarrhea, or allergic reactions. It is important to follow the prescribed dosage and withdrawal times to ensure food safety in animals intended for human consumption.

Resistance[edit]

The use of ceftiofur, like other antibiotics, can lead to the development of antibiotic resistance. It is crucial to use ceftiofur judiciously and in accordance with veterinary guidelines to minimize the risk of resistance.

-'''Ceftiofur''' is a broad-spectrum, third-generation [[cephalosporin]] antibiotic, primarily used in veterinary medicine. It is effective against a wide range of gram-positive and gram-negative bacteria, making it a valuable drug for treating various bacterial infections in animals. Ceftiofur is notable for its ability to combat bacteria that produce beta-lactamase, an enzyme that confers resistance to many other beta-lactam antibiotics.

+[[File:Ceftiofur.png|thumb|right|Chemical structure of Ceftiofur]]
-Ceftiofur works by inhibiting the synthesis of the bacterial cell wall. It binds to penicillin-binding proteins (PBPs) located inside the bacterial cell wall, disrupting the final transpeptidation step of peptidoglycan synthesis. This inhibition leads to the weakening of the cell wall and eventually causes cell lysis and death of the bacterium. The drug's action is bactericidal, meaning it directly kills bacteria.

+'''Ceftiofur''' is a [[cephalosporin]] antibiotic used in veterinary medicine.

Ceftiofur is commonly used to treat respiratory infections in cattle, swine, and horses.
-The pharmacokinetic properties of ceftiofur vary among different animal species. After administration, ceftiofur is rapidly metabolized to desfuroylceftiofur, its active metabolite. This metabolite retains the antibacterial activity of the parent compound. Ceftiofur can be administered via intramuscular, subcutaneous, or intravenous routes, depending on the animal species and the severity of the infection. The drug is primarily excreted through the kidneys.
-==Clinical Uses==
+== Mechanism of Action ==
-Ceftiofur is used in a variety of animal species, including cattle, swine, sheep, goats, dogs, and horses. It is indicated for the treatment of respiratory diseases, such as bacterial pneumonia, caused by susceptible strains of bacteria. In cattle, it is also used for the treatment of acute bovine respiratory disease (ABRD) and foot rot. In swine, ceftiofur is effective in treating bacterial swine respiratory disease.

+Ceftiofur works by inhibiting bacterial [[cell wall]] synthesis. It binds to penicillin-binding proteins (PBPs) located inside the bacterial cell wall, which are essential for the cross-linking of the [[peptidoglycan]] layer. This inhibition leads to the weakening of the cell wall and eventually causes bacterial cell lysis and death.
-As with all antibiotics, the use of ceftiofur can lead to the development of resistance. Bacteria may develop mechanisms to inactivate the drug, alter the drug's target site, reduce drug accumulation, or modify the metabolic pathway to bypass the drug's effect. Responsible use of ceftiofur, including adherence to prescribed dosages and treatment durations, is essential to minimize the risk of resistance development.
-==Safety and Side Effects==
+== Pharmacokinetics ==
-Ceftiofur is generally well tolerated in animals. However, as with any medication, side effects can occur. These may include injection site reactions, such as swelling or pain. Allergic reactions are rare but can happen and may manifest as rash, pruritus, or more severe symptoms requiring immediate veterinary attention.
-==Regulatory Status==
+Ceftiofur is administered via [[intramuscular injection|intramuscular]] or [[subcutaneous injection|subcutaneous]] routes. After administration, it is rapidly absorbed into the bloodstream and distributed throughout the body. Ceftiofur is metabolized in the liver to desfuroylceftiofur, which retains antibacterial activity. The drug and its metabolites are primarily excreted in the urine.
-The use of ceftiofur and other antibiotics in food-producing animals is regulated to ensure food safety. Withdrawal times, the period between the last administration of the antibiotic and the time when the animal can be legally slaughtered for food, are established to prevent antibiotic residues in meat. Regulatory agencies, such as the U.S. Food and Drug Administration (FDA), monitor the use of antibiotics in animals to safeguard human health.
-==Conclusion==
+== Clinical Uses ==
-Ceftiofur is a critical antibiotic in veterinary medicine, offering effective treatment against a broad range of bacterial infections in animals. Its use, however, must be judicious to prevent the development of antibiotic resistance, which can compromise its efficacy and the efficacy of related antibiotics in both veterinary and human medicine.
