Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefaclor, a second-generation cephalosporin, inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death. It exhibits bactericidal activity against susceptible organisms.
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.
250 mg orally every 8 hours; for severe infections, 500 mg orally every 8 hours.
1-2 g IV/IM every 8 hours; maximum 12 g/day for severe infections.

Terminal elimination half-life: 0.6-0.9 hours in adults with normal renal function. Prolonged to 2-3 hours in end-stage renal disease. Half-life does not increase significantly with hepatic impairment.
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.
Primarily renal: 80-90% of unchanged drug excreted by glomerular filtration and tubular secretion within 8 hours. Biliary excretion accounts for <5%; fecal elimination negligible.
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%.
