CEFMAX vs CEFTAZIDIME SODIUM 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.
Ceftazidime inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically PBP3, inhibiting transpeptidase activity and disrupting peptidoglycan cross-linking, leading to cell lysis and death.
1-2 g IV/IM every 8-12 hours; maximum 6 g/day.
1-2 g IV every 8 hours for pseudomonal infections; 500 mg to 1 g IV every 8-12 hours for uncomplicated UTIs.

2–4 hours in adults with normal renal function; prolonged to 20–40 hours in severe renal impairment (CrCl <10 mL/min).
1.5–2.0 hours in normal renal function; prolonged to 15–30 hours in ESRD.
Primarily renal (80–90% unchanged via glomerular filtration and tubular secretion); biliary/fecal elimination accounts for <5%.
Primarily renal (80–90% unchanged via glomerular filtration); biliary/fecal <1%.
