Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefpodoxime proxetil is a prodrug that is de-esterified in vivo to cefpodoxime, a third-generation cephalosporin antibiotic. It inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation, and disrupting peptidoglycan cross-linking, leading to cell lysis. It has broad-spectrum activity against Gram-positive and Gram-negative bacteria.
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.

Terminal elimination half-life of cefpodoxime is 2.2-2.8 hours in healthy adults; prolonged to 5.9-9.8 hours in moderate renal impairment (CrCl 10-30 mL/min) and up to 13-14 hours in severe impairment (CrCl <10 mL/min).
30-60 minutes in normal renal function; prolonged to 2-8 hours in severe renal impairment (CrCl <10 mL/min).
Renal excretion of unchanged drug (29-33%) and fecal/biliary elimination of inactive metabolites; 80% of radiolabeled dose recovered in urine and feces over 8 days.
Primarily renal (60-70% unchanged) via glomerular filtration and tubular secretion; minor biliary (5-10%) and fecal (<1%) elimination.
