Cefuzonam

An article about the antibiotic Cefuzonam

Cefuzonam

Cefuzonam is a cephalosporin antibiotic used in the treatment of various bacterial infections. It belongs to the class of beta-lactam antibiotics and is known for its broad-spectrum activity against both Gram-positive and Gram-negative bacteria.

Mechanism of Action

Cefuzonam works by inhibiting bacterial cell wall synthesis. It binds to penicillin-binding proteins (PBPs) located inside the bacterial cell wall, which leads to the interruption of peptidoglycan synthesis. This results in the weakening of the cell wall and ultimately causes bacterial cell lysis and death.

Pharmacokinetics

Cefuzonam is administered via intravenous or intramuscular injection. It is well-distributed throughout the body and achieves therapeutic concentrations in various tissues and fluids. The drug is primarily excreted unchanged in the urine, making it effective for treating urinary tract infections.

Clinical Uses

Cefuzonam is indicated for the treatment of a variety of infections, including:

• Respiratory tract infections
• Urinary tract infections
• Skin and soft tissue infections
• Intra-abdominal infections

Side Effects

Common side effects of Cefuzonam include:

• Gastrointestinal disturbances such as nausea and diarrhea
• Allergic reactions, including rash and pruritus
• Injection site reactions

Serious side effects are rare but may include anaphylaxis and Clostridium difficile infection.

Resistance

Bacterial resistance to Cefuzonam can occur through various mechanisms, such as the production of beta-lactamases that degrade the antibiotic, alterations in PBPs, and changes in bacterial permeability. Resistance is a growing concern and underscores the importance of appropriate antibiotic stewardship.
