Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Docetaxel binds to beta-tubulin, promoting microtubule assembly and inhibiting depolymerization, resulting in cell cycle arrest at G2/M phase and apoptosis.
Cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and autolysin activation, leading to cell lysis.
75 mg/m² intravenously over 1 hour every 3 weeks.
1-2 g IV/IM every 4-6 hours; maximum 12 g/day.

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).
Terminal elimination half-life: 0.5-1 hour (normal renal function); prolonged to 2-3 hours in anuria. Clinically, dosing every 6 hours is recommended.
Primarily renal excretion (70-80% as unchanged drug) with hepatic metabolism contributing to biliary/fecal elimination (20-30%).
Renal: 70-80% unchanged via glomerular filtration and tubular secretion; biliary: minimal (<5%); fecal: <1%.
