Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cephalothin is a first-generation cephalosporin with bactericidal activity by inhibiting bacterial cell wall synthesis via binding to penicillin-binding proteins (PBPs).
Cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking.
1-2 g IV every 4-6 hours; maximum 12 g/day.
1-2 g IV/IM every 8-12 hours; maximum 6 g/day.

Terminal elimination half-life: 0.5-1.0 hour in adults with normal renal function. In anuria, prolonged to 2.5-8 hours. Dose adjustment required for CrCl <50 mL/min.
Terminal elimination half-life is 1.5-2 hours; prolonged to 3-5 hours in moderate renal impairment (CrCl 30-50 mL/min) and up to 10-20 hours in severe impairment (CrCl <10 mL/min); dosing adjustment required for CrCl <50 mL/min.
Primarily renal (60-90% unchanged via glomerular filtration and tubular secretion). Minor biliary excretion (1-5%). Fecal elimination negligible.
Approximately 80-90% renal excretion as unchanged drug via glomerular filtration and tubular secretion; 10-20% biliary/fecal elimination.
