CEFOTAN vs TAZICEF
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 is a third-generation cephalosporin that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically PBP-3, leading to cell lysis and death.
1-2 g IV/IM every 12 hours for 5-10 days; up to 6 g/day for severe infections.
2 g intravenously every 8 hours for serious infections; 1 g intravenously every 8 hours for uncomplicated infections.

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.
2 hours (prolonged to 4-12 hours in renal impairment; anuria: 20-30 hours).
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 and tubular secretion); biliary/fecal <10%.
