CEFMAX vs MAXIPIME
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
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 8-12 hours; maximum 6 g/day.
1-2 g IV every 8-12 hours for most indications; maximum 2 g every 8 hours for severe infections.

2–4 hours in adults with normal renal function; prolonged to 20–40 hours in severe renal impairment (CrCl <10 mL/min).
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); biliary/fecal elimination accounts for <5%.
Primarily renal (approximately 80-90% as unchanged drug) via glomerular filtration and tubular secretion; biliary/fecal excretion is minimal (< 1%).
