Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Cephradine inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting the final transpeptidation step of peptidoglycan synthesis, leading to cell lysis and death. It is a first-generation cephalosporin with bactericidal activity.
Adult: 1-2 g IV or IM every 24 hours. Maximum 4 g/day for severe infections.
500 mg orally every 6 hours for 10 days.

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).
Terminal elimination half-life: 1.2 hours in adults with normal renal function; prolonged to 8-15 hours in severe renal impairment (CrCl <10 mL/min); clinical context: dosing interval adjustment required for renal impairment
Renal (33-67% unchanged), biliary (40-50% as active drug and metabolites), fecal (minor).
Renal excretion of unchanged drug: >90% (glomerular filtration and tubular secretion); biliary/fecal: <1%
