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.
Ceftriaxone is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking, leading to cell lysis and death.
1-2 g IV/IM every 8 hours; maximum 12 g/day for severe infections.
Adult: 1-2 g IV or IM every 24 hours. Maximum 4 g/day for severe infections.

Approximately 1.8 hours (range 1.2-2.2 h) in normal renal function; prolonged in renal impairment (up to 30-40 h in ESRD)
Terminal half-life 6-9 hours in healthy adults; prolonged to 12-15 hours in elderly and up to 30 hours in severe renal impairment (CrCl <10 mL/min).
Primarily renal (80-90% unchanged via glomerular filtration and tubular secretion); minimal biliary (1-2%); fecal (<1%)
Renal (33-67% unchanged), biliary (40-50% as active drug and metabolites), fecal (minor).
