Mechanism

Ceftaroline fosamil, a cephalosporin antibiotic, exhibits pharmacology similar to penicillins, acting as a beta-lactam to inhibit bacterial cell wall synthesis. It specifically targets penicillin-binding proteins (PBPs), which are enzymes crucial for the transpeptidation step in peptidoglycan cross-linking. This interference compromises the structural integrity of the bacterial cell wall, leading to osmotic instability and subsequent cell lysis.
