Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cephalexin is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting peptidoglycan cross-linking, leading to cell lysis.
Bactericidal antibiotic that inhibits cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically inhibiting transpeptidase activity, leading to cell lysis.
500 mg orally every 6 hours for uncomplicated infections; 1 g orally every 6 hours for more severe infections.
250 mg orally every 6 hours for adults with normal renal function.

Terminal elimination half-life: 0.5-1.0 hour (normal renal function); prolonged to 10-20 hours in severe renal impairment (CrCl <10 mL/min)
1.2-1.5 hours in normal renal function; prolonged in renal impairment (up to 10-20 hours in ESRD)
Renal: 80-90% unchanged via glomerular filtration and tubular secretion; biliary/fecal: <5%
Primarily renal (80-90% unchanged by glomerular filtration and tubular secretion); remainder biliary/fecal (<10%)
