CEFOTAN vs DOCEFREZ
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.
Docetaxel binds to beta-tubulin, promoting microtubule assembly and inhibiting depolymerization, resulting in cell cycle arrest at G2/M phase and apoptosis.
1-2 g IV/IM every 12 hours for 5-10 days; up to 6 g/day for severe infections.
75 mg/m² intravenously over 1 hour every 3 weeks.

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.
Terminal elimination half-life is 4.5-6.0 hours in patients with normal renal function; prolonged to 12-24 hours in severe renal impairment (CrCl <30 mL/min).
Primarily renal (unchanged); ~88% excreted in urine within 24 hours. Biliary/fecal elimination is negligible (<1% as metabolites).
Primarily renal excretion (70-80% as unchanged drug) with hepatic metabolism contributing to biliary/fecal elimination (20-30%).
