CEFADROXIL vs CEFMAX
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.
CEFMAX (cefepime) is a fourth-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically PBP-3 in Gram-negative bacteria and PBP-1a/1b in Gram-positive bacteria, thereby disrupting peptidoglycan cross-linking and leading to cell lysis. It has zwitterionic properties facilitating rapid penetration through Gram-negative outer membranes and is relatively resistant to hydrolysis by many beta-lactamases, including AmpC beta-lactamases.
1-2 g orally once daily or divided into two doses every 12 hours.

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
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).
2–4 hours in adults with normal renal function; prolonged to 20–40 hours in severe renal impairment (CrCl <10 mL/min).
Primarily renal (90-95% unchanged via glomerular filtration and tubular secretion); minor biliary/fecal (<5%).
Primarily renal (80–90% unchanged via glomerular filtration and tubular secretion); biliary/fecal elimination accounts for <5%.
