Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Ceftriaxone inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby interfering with peptidoglycan cross-linking and leading to cell lysis.
