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.
Ceftriaxone inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby interfering with peptidoglycan cross-linking and leading to cell lysis.
200 mg orally every 12 hours
1-2 g IV or IM every 24 hours; maximum 4 g/day for serious infections.

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 half-life ~6-8 hours in adults with normal renal function; prolonged to 12-24 hours in neonates and elderly.
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.
Renal (33-67%) and biliary (40-50%); primarily excreted unchanged. Dual elimination: ~50% renal, ~50% biliary/fecal.
