Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cephapirin sodium is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), primarily PBP1 and PBP3, thereby inhibiting transpeptidation and disrupting peptidoglycan cross-linking, leading to cell lysis mediated by autolytic enzymes.
Docetaxel binds to beta-tubulin, promoting microtubule assembly and inhibiting depolymerization, resulting in cell cycle arrest at G2/M phase and apoptosis.
500 mg to 1 g IM or IV every 6 hours.
75 mg/m² intravenously over 1 hour every 3 weeks.

0.5-1.0 hours; prolonged to 2-5 hours in renal impairment, 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).
Renal: 80-90% unchanged via glomerular filtration and tubular secretion; biliary/fecal: <5%.
Primarily renal excretion (70-80% as unchanged drug) with hepatic metabolism contributing to biliary/fecal elimination (20-30%).
