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), inhibiting peptidoglycan cross-linking.
1-2 g IV every 4-6 hours; maximum 12 g/day.
1-2 g IV/IM every 8 hours for moderate to severe infections; maximum 12 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.
1.5-2 hours in adults with normal renal function; prolonged to 20-30 hours in end-stage renal disease (CrCl <10 mL/min).
Primarily renal (60-90% unchanged via glomerular filtration and tubular secretion). Minor biliary excretion (1-5%). Fecal elimination negligible.
Renal: 80-90% unchanged via glomerular filtration and tubular secretion. Biliary/fecal: minimal (<5%).
