Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefazolin, a first-generation cephalosporin, inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting peptidoglycan cross-linking and autolytic enzyme inhibition.
Cephalothin is a first-generation cephalosporin that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby blocking peptidoglycan cross-linking. It has activity against gram-positive cocci (e.g., Staphylococcus aureus, Streptococcus pyogenes) and some gram-negative bacilli (e.g., Escherichia coli, Klebsiella pneumoniae).

1.5-2 hours in adults with normal renal function; prolonged to 10-30 hours in ESRD (CrCl <10 mL/min); anephric patients up to 40 hours.
0.5-1 hour in patients with normal renal function; prolonged to 2-8 hours in moderate renal impairment (CrCl 30-50 mL/min); up to 20-30 hours in end-stage renal disease; due to rapid elimination, frequent dosing (q4-6h) is required for continuous bactericidal levels.
Primarily renal (80-96% unchanged within 24 hours via glomerular filtration and tubular secretion); minimal biliary (<1%) and fecal (<1%).
Primarily renal (60-90% unchanged) via tubular secretion and glomerular filtration; minor biliary excretion (less than 5%); hepatic metabolism to desacetylcephalothin (active but less potent) accounts for about 20-30% of dose; fecal elimination negligible.
