Chemical structure of Cefpiramide

Cefpiramide is characterized by its beta-lactam ring, which is essential for its antibacterial activity. The chemical structure of cefpiramide allows it to inhibit bacterial cell wall synthesis, leading to cell lysis and death.

Mechanism of Action

Cefpiramide works by binding to penicillin-binding proteins (PBPs) located inside the bacterial cell wall. This binding inhibits the final transpeptidation step of peptidoglycan synthesis, which is crucial for bacterial cell wall integrity. As a result, the bacterium is unable to maintain its cell wall, leading to cell death.

Clinical Uses

Cefpiramide is used to treat a variety of infections, including:

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

Pharmacokinetics

Cefpiramide 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.

Side Effects

Common side effects of cefpiramide include:

• Gastrointestinal disturbances such as nausea and diarrhea
• Allergic reactions, including rash and anaphylaxis
• Hematological effects such as eosinophilia and thrombocytopenia
