CEFEPIME HYDROCHLORIDE vs KEFLEX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bactericidal; inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase and carboxypeptidase activity, leading to cell lysis.
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 every 8-12 hours; for uncomplicated urinary tract infections, 500 mg IV every 12 hours.
250-500 mg orally every 6 hours; maximum 4 g/day.

2-2.3 hours in healthy adults (prolonged to 13-15 hours in severe renal impairment; requires dosage adjustment).
0.5–1.2 hours in patients with normal renal function (CrCl >50 mL/min); prolonged to >20 hours in ESRD.
Primarily renal (≈85% unchanged via glomerular filtration and tubular secretion); biliary/fecal <1%.
Primarily renal (90% or more unchanged via glomerular filtration and tubular secretion); small amounts biliary/fecal (<5%).
