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), blocking transpeptidation, and activating autolytic enzymes.
Cephalexin 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.
1-2 g IV/IM every 8-12 hours; maximum 12 g/day for severe infections.
250-500 mg orally every 6 hours; maximum 4 g/day.

Terminal elimination half-life is approximately 0.6-1.2 hours in adults with normal renal function. In neonates, it is prolonged (2-6 hours). In renal impairment, half-life extends significantly (up to 15-30 hours in anuria), requiring dose adjustment.
0.5–1.2 hours in patients with normal renal function (CrCl >50 mL/min); prolonged to >20 hours in ESRD.
Primarily renal: approximately 60-80% of the dose is excreted unchanged in urine via glomerular filtration and tubular secretion. Small amounts are eliminated in bile (<10%) and feces (<1%).
Primarily renal (90% or more unchanged via glomerular filtration and tubular secretion); small amounts biliary/fecal (<5%).
