CEFMAX vs ROCEPHIN W/ DEXTROSE IN PLASTIC 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 beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
1-2 g IV/IM every 8-12 hours; maximum 6 g/day.
1-2 g IV or IM once daily; maximum 4 g/day. For serious infections, 2 g IV every 12 hours.

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: 6-8 hours in adults with normal renal function; prolonged up to 15 hours in elderly; significantly increased in renal impairment (up to 20-30 hours in ESRD).
Primarily renal (80–90% unchanged via glomerular filtration and tubular secretion); biliary/fecal elimination accounts for <5%.
Renal (33-67% unchanged) and biliary (40-50% unchanged and microbiologically inactive metabolite). Approximately 50% excreted in urine, 50% in feces.
