CEFADYL vs CEPHRADINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bactericidal; inhibits cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and autolysin activation.
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.
1-2 g IV/IM every 6 hours for moderate to severe infections; maximum 12 g/day.
250-500 mg orally every 6 hours; 500 mg to 1 g intramuscularly or intravenously every 6 hours. Maximum: 4 g/day.

30-60 minutes in adults with normal renal function; prolonged to 10-20 hours in end-stage renal disease. Requires dose adjustment for CrCl <30 mL/min.
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).
Renal: 90-95% unchanged via glomerular filtration and tubular secretion. Biliary: <1%. Fecal: minimal.
Primarily renal (≥90% unchanged via glomerular filtration and tubular secretion); minor biliary/fecal (<10%).
