Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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).
Ceftriaxone is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
1-2 g IV every 4-6 hours; maximum 12 g/day.
1-2 g IV or IM once daily; maximum 4 g/day. For serious infections, 2 g IV every 12 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.
Terminal elimination half-life: 6-8 hours in adults with normal renal function; prolonged up to 15 hours in elderly; significantly increased in renal impairment (up to 20-30 hours in ESRD).
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.
Renal (33-67% unchanged) and biliary (40-50% unchanged and microbiologically inactive metabolite). Approximately 50% excreted in urine, 50% in feces.
