CEFMAX vs CEFOTAN 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.
Cefotetan is a cephamycin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting transpeptidation and cross-linking of peptidoglycan. It has broad-spectrum activity against gram-negative and gram-positive bacteria, including anaerobes, and is resistant to beta-lactamases.
1-2 g IV/IM every 8-12 hours; maximum 6 g/day.
1 to 2 g intravenously or intramuscularly every 12 hours for 5 to 10 days. Maximum dose 6 g daily.

2–4 hours in adults with normal renal function; prolonged to 20–40 hours in severe renal impairment (CrCl <10 mL/min).
2.8-3.2 hours in normal renal function; prolonged to 12-30 hours in severe renal impairment (CrCl <10 mL/min).
Primarily renal (80–90% unchanged via glomerular filtration and tubular secretion); biliary/fecal elimination accounts for <5%.
Primarily renal (76-85% unchanged in urine via glomerular filtration and tubular secretion); biliary excretion accounts for <10%, with small amounts in feces.
