Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Cephalexin is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting peptidoglycan cross-linking, leading to cell lysis.
1-2 g IV every 4-6 hours; maximum 12 g/day.
500 mg orally every 6 hours for uncomplicated infections; 1 g orally every 6 hours for more severe infections.

30-60 minutes in normal renal function; prolonged to 2-8 hours in severe renal impairment (CrCl <10 mL/min).
Terminal elimination half-life: 0.5-1.0 hour (normal renal function); prolonged to 10-20 hours in severe renal impairment (CrCl <10 mL/min)
Primarily renal (60-70% unchanged) via glomerular filtration and tubular secretion; minor biliary (5-10%) and fecal (<1%) elimination.
Renal: 80-90% unchanged via glomerular filtration and tubular secretion; biliary/fecal: <5%
