CEFACLOR vs CEPHALOTHIN SODIUM
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), disrupting peptidoglycan cross-linking.
Cephalothin is a first-generation cephalosporin with bactericidal activity by inhibiting bacterial cell wall synthesis via binding to penicillin-binding proteins (PBPs).
250-500 mg orally every 8 hours
1-2 g IV every 4-6 hours; maximum 12 g/day.

Terminal elimination half-life: 0.5-1 hour; prolonged to 2-3 hours in renal impairment
Terminal elimination half-life: 0.5-1.0 hour in adults with normal renal function. In anuria, prolonged to 2.5-8 hours. Dose adjustment required for CrCl <50 mL/min.
Clinical Note
moderateCefaclor + Probenecid
"The serum concentration of Probenecid can be increased when it is combined with Cefaclor."
Clinical Note
moderateCefaclor + Picosulfuric acid
"The therapeutic efficacy of Picosulfuric acid can be decreased when used in combination with Cefaclor."
Clinical Note
moderateWarfarin + Cefaclor
"Warfarin may increase the anticoagulant activities of Cefaclor."
Clinical Note
moderatePhenprocoumon + Cefaclor
Renal: 60-85% unchanged in urine within 8 hours; biliary/fecal: minor, ~5%
Primarily renal (60-90% unchanged via glomerular filtration and tubular secretion). Minor biliary excretion (1-5%). Fecal elimination negligible.
