Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cephapirin sodium is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), primarily PBP1 and PBP3, thereby inhibiting transpeptidation and disrupting peptidoglycan cross-linking, leading to cell lysis mediated by autolytic enzymes.
Ceftriaxone is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking, leading to cell lysis and death.
500 mg to 1 g IM or IV every 6 hours.
Adult: 1-2 g IV or IM every 24 hours. Maximum 4 g/day for severe infections.

0.5-1.0 hours; prolonged to 2-5 hours in renal impairment, requiring dose adjustment.
Terminal half-life 6-9 hours in healthy adults; prolonged to 12-15 hours in elderly and up to 30 hours in severe renal impairment (CrCl <10 mL/min).
Renal: 80-90% unchanged via glomerular filtration and tubular secretion; biliary/fecal: <5%.
Renal (33-67% unchanged), biliary (40-50% as active drug and metabolites), fecal (minor).
