A third-generation parenteral cephalosporin antibiotic with potent activity against Pseudomonas aeruginosa and other gram-negative pathogens, used for serious hospital-acquired infections including pneumonia, bacteremia, and meningitis. It is a cornerstone antibiotic in treating gram-negative infections in immunocompromised patients. Resistance can emerge, and susceptibility testing is recommended.

آلية العمل

Disrupts bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting the final transpeptidation step of peptidoglycan synthesis. The resulting cell wall defects cause osmotic instability and bacteriolysis.
