CEFAZOLIN AND DEXTROSE vs CEPHALOTHIN SODIUM
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.
Cephalothin is a first-generation cephalosporin with bactericidal activity by inhibiting bacterial cell wall synthesis via binding to penicillin-binding proteins (PBPs).
1-2 g IV/IM every 8 hours; maximum 12 g/day.
1-2 g IV every 4-6 hours; maximum 12 g/day.

1.8 hours (prolonged to 20-40 hours in severe renal impairment, CrCl <10 mL/min)
Terminal elimination half-life: 0.5-1.0 hour in adults with normal renal function. In anuria, prolonged to 2.5-8 hours. Dose adjustment required for CrCl <50 mL/min.
Renal (80-90% unchanged via glomerular filtration and tubular secretion); biliary/fecal (<5%)
Primarily renal (60-90% unchanged via glomerular filtration and tubular secretion). Minor biliary excretion (1-5%). Fecal elimination negligible.
