Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cephradine 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.
Cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and autolysin activation, leading to cell lysis.

Terminal elimination half-life 0.5–1.5 hours (normal renal function); prolonged to 6–15 hours in severe renal impairment (CrCl <10 mL/min).
Terminal elimination half-life: 0.5-1 hour (normal renal function); prolonged to 2-3 hours in anuria. Clinically, dosing every 6 hours is recommended.
Primarily renal (≥90% unchanged via glomerular filtration and tubular secretion); minor biliary/fecal (<10%).
Renal: 70-80% unchanged via glomerular filtration and tubular secretion; biliary: minimal (<5%); fecal: <1%.
