Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefuroxime inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting the final transpeptidation step of peptidoglycan synthesis, leading to cell lysis.
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.
750 mg to 1.5 g intramuscularly or intravenously every 8 hours; for severe infections, 1.5 g intravenously every 6 to 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.

1.2-1.6 hours in adults with normal renal function (Clcr >80 mL/min); prolonged to 10-20 hours in end-stage renal disease (Clcr <10 mL/min).
0.5–1.2 hours in normal renal function; prolonged to 2–4 hours in severe renal impairment (CrCl <10 mL/min).
Primarily renal (80-90% unchanged via glomerular filtration and tubular secretion); biliary/fecal <10%.
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.
