CEFACLOR vs CEPHALOTHIN SODIUM W/ DEXTROSE IN PLASTIC CONTAINER
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 antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death. It has bactericidal activity against susceptible gram-positive and some gram-negative bacteria.
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
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
30-60 minutes in normal renal function; prolonged to 2-8 hours in severe renal impairment (CrCl <10 mL/min).
Renal: 60-85% unchanged in urine within 8 hours; biliary/fecal: minor, ~5%
Primarily renal (60-70% unchanged) via glomerular filtration and tubular secretion; minor biliary (5-10%) and fecal (<1%) elimination.
