CEFACLOR vs VELOSEF
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.
Cephalosporin antibiotic; inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking.
250-500 mg orally every 8 hours
250-500 mg orally every 6 hours or 1-2 g intramuscularly/intravenously every 6-12 hours for moderate to severe infections.
None Documented

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
1-2 hours (normal renal function); prolonged to 10-30 hours in severe renal impairment (CrCl <10 mL/min)
Renal: 60-85% unchanged in urine within 8 hours; biliary/fecal: minor, ~5%
Primarily renal (80-90% unchanged via glomerular filtration and tubular secretion); small biliary/fecal (5-10%)
Category A/B
