CEFEPIME AND DEXTROSE IN DUPLEX CONTAINER vs CEPHALOTHIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefepime is a fourth-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), particularly PBP 3, leading to cell lysis and death. It has activity against both gram-positive and gram-negative bacteria.
Cephalothin is a first-generation cephalosporin that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby blocking peptidoglycan cross-linking. It has activity against gram-positive cocci (e.g., Staphylococcus aureus, Streptococcus pyogenes) and some gram-negative bacilli (e.g., Escherichia coli, Klebsiella pneumoniae).
1-2 g intravenously every 8-12 hours; typical dose 1 g IV q12h for most infections, 2 g IV q8h for severe infections.
1-2 g IV every 4-6 hours; maximum 12 g/day.

Approximately 2 hours in adults with normal renal function; prolonged to 4–8 hours in mild-to-moderate renal impairment and up to 13–30 hours in severe impairment (CrCl <30 mL/min).
0.5-1 hour in patients with normal renal function; prolonged to 2-8 hours in moderate renal impairment (CrCl 30-50 mL/min); up to 20-30 hours in end-stage renal disease; due to rapid elimination, frequent dosing (q4-6h) is required for continuous bactericidal levels.
Primarily renal (≥85% unchanged in urine via glomerular filtration and tubular secretion); biliary/fecal excretion minimal (<1%).
Primarily renal (60-90% unchanged) via tubular secretion and glomerular filtration; minor biliary excretion (less than 5%); hepatic metabolism to desacetylcephalothin (active but less potent) accounts for about 20-30% of dose; fecal elimination negligible.
