CEFOXITIN IN PLASTIC CONTAINER vs TAZIDIME
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefoxitin inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically PBP1a, PBP1b, and PBP2, thereby inhibiting transpeptidation and leading to cell lysis. It is a cephamycin antibiotic resistant to beta-lactamase hydrolysis due to a 7-alpha-methoxy group.
Ceftazidime inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and disrupting peptidoglycan cross-linking.
1-2 g IV every 6-8 hours; maximum 12 g/day
1 to 2 g IV/IM every 8 hours; maximum 6 g/day.

Terminal elimination half-life: 0.7-1.5 hours (approximately 45-90 minutes); prolonged to 2-6 hours in moderate renal impairment (CrCl 30-50 mL/min) and up to 10-20 hours in severe renal impairment (CrCl <10 mL/min).
Clinical Note
moderateCeftazidime + Probenecid
"The serum concentration of Probenecid can be increased when it is combined with Ceftazidime."
Clinical Note
moderateCeftazidime + Picosulfuric acid
"The therapeutic efficacy of Picosulfuric acid can be decreased when used in combination with Ceftazidime."
Clinical Note
moderateWarfarin + Ceftazidime
"Warfarin may increase the anticoagulant activities of Ceftazidime."
Clinical Note
moderatePhenprocoumon + Ceftazidime
1.9 hours (range 1.5-2.8 hours); prolonged in renal impairment (up to 20 hours in ESRD).
Renal: 85-95% unchanged via glomerular filtration and tubular secretion; biliary: <2%; fecal: trace.
Primarily renal (80-90% unchanged via glomerular filtration), biliary/fecal <5%.
