Cefazedone

Cefazedone

Cefazedone is a cephalosporin antibiotic used in the treatment of various bacterial infections. It is a second-generation cephalosporin, which means it was developed after the first generation of cephalosporins and has a broader spectrum of activity.

Mechanism of Action

Cefazedone works by inhibiting the synthesis of the bacterial cell wall. It binds to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall. This binding leads to the inhibition of the third and last stage of bacterial cell wall synthesis, which is ultimately lethal to the bacteria.

Pharmacokinetics

After administration, Cefazedone is well absorbed and widely distributed in the body. It is metabolized in the liver and excreted in the urine. The half-life of Cefazedone is approximately 2 hours.

Clinical Use

Cefazedone is used to treat a variety of bacterial infections, including those caused by Staphylococcus aureus, Streptococcus pneumoniae, and Escherichia coli. It is also used in the prophylaxis of surgical infections.

Side Effects

Common side effects of Cefazedone include nausea, vomiting, diarrhea, and allergic reactions. Serious side effects can include Clostridium difficile associated diarrhea, Stevens-Johnson syndrome, and anaphylaxis.

Resistance

Bacterial resistance to Cefazedone can occur through several mechanisms, including the production of beta-lactamase enzymes, alteration of PBPs, and changes in outer membrane permeability.
