Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefotaxime is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically PBP-1A and PBP-3, leading to cell lysis and death.
Cephalothin is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death. It has bactericidal activity against susceptible gram-positive and some gram-negative bacteria.
1-2 g IV/IM every 8 hours; maximum 12 g/day for severe infections.
1-2 g IV every 4-6 hours; maximum 12 g/day.

Terminal elimination half-life is 0.9-1.5 hours in adults with normal renal function; prolonged to 2.5-10 hours in renal impairment (CrCl <20 mL/min). In neonates, half-life is 3-6 hours.
30-60 minutes in normal renal function; prolonged to 2-8 hours in severe renal impairment (CrCl <10 mL/min).
Renal (50-60% unchanged), biliary (5-10%), with approximately 20-30% metabolized to desacetylcefotaxime (also renally eliminated). Total renal elimination of parent drug and metabolite accounts for >80%.
Primarily renal (60-70% unchanged) via glomerular filtration and tubular secretion; minor biliary (5-10%) and fecal (<1%) elimination.
