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), inhibiting transpeptidation and disrupting peptidoglycan cross-linking. This leads to cell lysis and death, primarily in actively dividing bacteria.
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.
For uncomplicated infections: 1-2 g IV every 8 hours. For severe infections: up to 2 g IV every 4 hours. Administered as an IV infusion over 30-60 minutes.
1-2 g IV/IM every 8-12 hours; maximum 6 g/day.

1.8 hours (normal renal function); prolonged to 10-30 hours in severe renal impairment (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% unchanged via glomerular filtration and tubular secretion; biliary/fecal: <1%
Primarily renal (80–90% unchanged via glomerular filtration and tubular secretion); biliary/fecal elimination accounts for <5%.
