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.
Cefepime is a fourth-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby disrupting peptidoglycan cross-linking. It has enhanced activity against Gram-negative bacteria due to rapid penetration through the outer membrane and low affinity for β-lactamases.
1-2 g IV/IM every 8 hours; maximum 12 g/day for severe infections.
1-2 g IV every 8-12 hours for most indications; maximum 2 g every 8 hours 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 elimination half-life is approximately 2-2.5 hours in adults with normal renal function; extends to 8-12 hours in moderate renal impairment (CrCl 30-60 mL/min) and up to 20-24 hours in severe impairment (CrCl < 30 mL/min).
Primarily renal (80-90% unchanged via glomerular filtration and tubular secretion); minimal biliary (1-2%); fecal (<1%)
Primarily renal (approximately 80-90% as unchanged drug) via glomerular filtration and tubular secretion; biliary/fecal excretion is minimal (< 1%).
