Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefazolin is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically PBP1a, PBP1b, PBP2a, PBP2b, PBP2x, PBP3, and PBP4, thereby preventing cross-linking of peptidoglycan chains. This leads to cell lysis and death.
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 8 hours; maximum 12 g/day for severe infections.
75 mg/m² intravenously over 1 hour every 3 weeks.

Approximately 1.8 hours (range 1.2-2.2 h) in normal renal function; prolonged in renal impairment (up to 30-40 h in ESRD)
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 (80-90% unchanged via glomerular filtration and tubular secretion); minimal biliary (1-2%); fecal (<1%)
Primarily renal excretion (70-80% as unchanged drug) with hepatic metabolism contributing to biliary/fecal elimination (20-30%).
