CEFPODOXIME PROXETIL vs CEPHALOTHIN SODIUM
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 with bactericidal activity by inhibiting bacterial cell wall synthesis via binding to penicillin-binding proteins (PBPs).
200 mg orally every 12 hours
1-2 g IV every 4-6 hours; maximum 12 g/day.

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).
Terminal elimination half-life: 0.5-1.0 hour in adults with normal renal function. In anuria, prolonged to 2.5-8 hours. Dose adjustment required for CrCl <50 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 (60-90% unchanged via glomerular filtration and tubular secretion). Minor biliary excretion (1-5%). Fecal elimination negligible.
