Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefazolin is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically PBP1a, PBP1b, PBP2a, PBP2b, PBP2x, PBP3, and PBP4, thereby preventing cross-linking of peptidoglycan chains. This leads to cell lysis and death.
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.
1-2 g IV/IM every 8 hours; maximum 12 g/day for severe infections.
