CEFAZOLIN AND DEXTROSE vs KEFLEX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bactericidal agent inhibiting bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking, leading to cell lysis. Dextrose provides osmotic diuresis and energy source.
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 12 g/day.
250-500 mg orally every 6 hours; maximum 4 g/day.

1.8 hours (prolonged to 20-40 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.
Renal (80-90% unchanged via glomerular filtration and tubular secretion); biliary/fecal (<5%)
