Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
First-generation cephalosporin that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking.
Cephalexin is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
1-2 g IV/IM every 8 hours; maximum 6 g/day.
250-500 mg orally every 6 hours; maximum 4 g/day.

1.5-2 hours in adults with normal renal function; prolongs significantly in renal impairment (up to 30 hours in anuria).
0.5–1.2 hours in patients with normal renal function (CrCl >50 mL/min); prolonged to >20 hours in ESRD.
Primarily renal (80-90% unchanged by glomerular filtration and tubular secretion); small amounts biliary (<1%) and fecal.
