CEFACLOR vs ULTRACEF
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.
Cefadroxil, a first-generation cephalosporin, inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and disrupting peptidoglycan cross-linking, leading to cell lysis. It is bactericidal against susceptible organisms.
250-500 mg orally every 8 hours
250 mg orally every 6 hours or 500 mg orally every 12 hours for uncomplicated urinary tract infections; 1 g orally every 12 hours for complicated urinary tract infections.

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
0.5–1.2 hours in normal renal function; prolonged to 2–4 hours in severe renal impairment (CrCl <10 mL/min).
Renal: 60-85% unchanged in urine within 8 hours; biliary/fecal: minor, ~5%
Approximately 90% of an oral dose is excreted unchanged in urine via glomerular filtration and tubular secretion; less than 1% is excreted in feces via biliary elimination.
