CEFMAX vs CEFTRIAXONE AND DEXTROSE IN DUPLEX CONTAINER
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.
Ceftriaxone is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting peptidoglycan cross-linking. It has bactericidal activity against a broad range of gram-positive and gram-negative bacteria.
1-2 g IV/IM every 8-12 hours; maximum 6 g/day.
1-2 g intravenously or intramuscularly every 24 hours. Maximum dose: 4 g daily.

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 5.8-8.7 hours in adults, prolonged to 12-24 hours in elderly, and up to 30-72 hours in neonates. No dose adjustment in renal impairment alone; adjust in severe hepatic impairment.
Primarily renal (80–90% unchanged via glomerular filtration and tubular secretion); biliary/fecal elimination accounts for <5%.
Renal (33-67% unchanged) and biliary (up to 40% as unchanged drug and microbiologically inactive metabolites); fecal elimination of unabsorbed drug is minimal. Dose adjustment required in combined renal and hepatic impairment.
