Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Binds to penicillin-binding proteins (PBPs) in bacterial cell wall, inhibiting peptidoglycan cross-linking, leading to cell lysis and death.
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 8-12 hours; severe infections: up to 2 g every 6-8 hours; maximum 12 g/day.
250-500 mg orally every 6 hours; maximum 4 g/day.

1.5-2 hours; prolonged to 10-30 hours in severe renal impairment (CrCl <10 mL/min)
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), with biliary/fecal elimination being minor (<10%)
Primarily renal (90% or more unchanged via glomerular filtration and tubular secretion); small amounts biliary/fecal (<5%).
