CEFADROXIL vs CEFZIL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefadroxil is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting transpeptidase activity and disrupting peptidoglycan cross-linking.
Cefprozil inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting peptidoglycan cross-linking.
1-2 g orally once daily or divided into two doses every 12 hours.
500 mg orally twice daily for 10 days; for uncomplicated skin infections, 250 mg twice daily or 500 mg once daily.

Terminal elimination half-life 1.1-1.5 hours in normal renal function; prolonged to 20-30 hours in end-stage renal disease (CrCl <10 mL/min).
Clinical Note
moderateCefadroxil + Probenecid
"The serum concentration of Probenecid can be increased when it is combined with Cefadroxil."
Clinical Note
moderateCefadroxil + Picosulfuric acid
"The therapeutic efficacy of Picosulfuric acid can be decreased when used in combination with Cefadroxil."
Clinical Note
moderateWarfarin + Cefadroxil
"Warfarin may increase the anticoagulant activities of Cefadroxil."
Clinical Note
moderatePhenprocoumon + Cefadroxil
1.2-1.5 hours in healthy adults; prolonged in renal impairment (e.g., up to 6-8 hours in severe renal failure)
Primarily renal (90-95% unchanged via glomerular filtration and tubular secretion); minor biliary/fecal (<5%).
Renal: 80-91% unchanged in urine; biliary/fecal: minimal (<5%)
