CEFEPIME HYDROCHLORIDE vs CEFMAX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bactericidal; inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase and carboxypeptidase activity, leading to cell lysis.
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 8-12 hours; for uncomplicated urinary tract infections, 500 mg IV every 12 hours.
1-2 g IV/IM every 8-12 hours; maximum 6 g/day.

2-2.3 hours in healthy adults (prolonged to 13-15 hours in severe renal impairment; requires dosage adjustment).
2–4 hours in adults with normal renal function; prolonged to 20–40 hours in severe renal impairment (CrCl <10 mL/min).
Primarily renal (≈85% 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%.
