CEFOXITIN vs FORTAZ
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefoxitin is a cephamycin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), particularly PBP-1 and PBP-3, thereby inhibiting the final transpeptidation step of peptidoglycan synthesis. This leads to cell lysis and death. It is resistant to beta-lactamases produced by many Gram-negative and Gram-positive bacteria.
Inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting peptidoglycan cross-linking, leading to cell lysis.
1-2 g IV every 6-8 hours; maximum 12 g/day.
1-2 g IV/IM every 8-12 hours; maximum 6 g/day for serious infections.

Clinical Note
moderateCefoxitin + Probenecid
"The serum concentration of Probenecid can be increased when it is combined with Cefoxitin."
Clinical Note
moderateCefoxitin + Picosulfuric acid
"The therapeutic efficacy of Picosulfuric acid can be decreased when used in combination with Cefoxitin."
Clinical Note
moderateWarfarin + Cefoxitin
"Warfarin may increase the anticoagulant activities of Cefoxitin."
Clinical Note
moderatePhenprocoumon + Cefoxitin
Terminal elimination half-life is approximately 0.7–1.1 hours (mean 0.8 h) in adults with normal renal function, extending to 5–10 hours in severe renal impairment (CrCl <10 mL/min).
2 hours (normal renal function); prolonged to 12-20 hours in ESRD
Renal excretion of unchanged drug accounts for approximately 85% of elimination; biliary excretion is minimal (<1%); fecal elimination is negligible.
Primarily renal (80-90% unchanged) via glomerular filtration and tubular secretion; 5-10% biliary/fecal
