Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and causing cell lysis.
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.
1 to 2 g intravenously every 8 to 12 hours; maximum 6 g per day.
500 mg orally every 6 hours for uncomplicated infections; 1 g orally every 6 hours for more severe infections.

Approximately 2 hours in patients with normal renal function; prolonged to 3-5 hours in mild-moderate renal impairment and >20 hours in severe renal impairment (CrCl <10 mL/min).
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)
Primarily renal (80-90% unchanged via glomerular filtration and tubular secretion); biliary/fecal elimination accounts for <10%.
Renal: 80-90% unchanged via glomerular filtration and tubular secretion; biliary/fecal: <5%
