CEFOTAN vs TAZIDIME
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefotetan is a cephamycin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting peptidoglycan cross-linking, and activating autolytic enzymes.
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/IM every 12 hours for 5-10 days; up to 6 g/day for severe infections.
1 to 2 g IV/IM every 8 hours; maximum 6 g/day.

Terminal elimination half-life: 4.5 hours (intravenous). In patients with renal impairment (CrCl <30 mL/min), half-life extends to approximately 20–30 hours, requiring dose adjustment.
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).
Primarily renal (unchanged); ~88% excreted in urine within 24 hours. Biliary/fecal elimination is negligible (<1% as metabolites).
Primarily renal (80-90% unchanged via glomerular filtration), biliary/fecal <5%.
