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), thereby disrupting peptidoglycan cross-linking.
CEFMAX (cefepime) is a fourth-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically PBP-3 in Gram-negative bacteria and PBP-1a/1b in Gram-positive bacteria, thereby disrupting peptidoglycan cross-linking and leading to cell lysis. It has zwitterionic properties facilitating rapid penetration through Gram-negative outer membranes and is relatively resistant to hydrolysis by many beta-lactamases, including AmpC beta-lactamases.
1-2 g IV every 8 hours. For serious infections, up to 2 g IV every 6 hours.
1-2 g IV/IM every 8-12 hours; maximum 6 g/day.

1.8 hours in normal renal function. Prolonged to 12-24 hours in end-stage renal disease (CrCl <10 mL/min).
2–4 hours in adults with normal renal function; prolonged to 20–40 hours in severe renal impairment (CrCl <10 mL/min).
Renal: 80-90% unchanged by glomerular filtration and tubular secretion. Biliary: minor (<1%). Fecal: negligible.
Primarily renal (80–90% unchanged via glomerular filtration and tubular secretion); biliary/fecal elimination accounts for <5%.
