CEFEPIME IN PLASTIC 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. It demonstrates broad-spectrum activity against gram-positive and gram-negative bacteria, including Pseudomonas aeruginosa.
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 for moderate to severe infections; up to 2 g every 8 hours for severe infections or febrile neutropenia.
1-2 g IV every 4-6 hours; maximum 12 g/day.

2.0–2.3 hours in adults with normal renal function; prolonged to 13–26 hours in end-stage renal disease.
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.
Renal: approximately 85% of the dose excreted unchanged in urine; biliary/fecal: less than 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.
