Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ceftazidime inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically PBP3, thereby disrupting peptidoglycan cross-linking and leading to cell lysis. It is a third-generation cephalosporin with broad-spectrum activity against Gram-negative bacteria, including Pseudomonas aeruginosa.
Cephalothin is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and autolysin activity, leading to cell lysis and death.
