Fortum (500mg) 1 Vial Injection

Ceftazidime is a beta-lactam antibiotic that belongs to the third-generation cephalosporin class. Its primary mechanism of action is inhibiting bacterial cell wall synthesis, leading to cell lysis. Ceftazidime specifically binds to and inhibits penicillin-binding proteins (PBPs), which are essential for cross-linking peptidoglycan strands during cell wall formation. By disrupting these PBPs, ceftazidime weakens the bacterial cell wall, resulting in osmotic instability and ultimately causing bacterial death. This antibiotic has a broad spectrum of activity against both Gram-positive and Gram-negative bacteria, including Pseudomonas aeruginosa, making it effective in treating various infections.
