CEFEPIME IN PLASTIC CONTAINER vs KEFLEX
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.
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 intravenously every 8-12 hours for moderate to severe infections; up to 2 g every 8 hours for severe infections or febrile neutropenia.
250-500 mg orally every 6 hours; maximum 4 g/day.

2.0–2.3 hours in adults with normal renal function; prolonged to 13–26 hours in end-stage renal disease.
0.5–1.2 hours in patients with normal renal function (CrCl >50 mL/min); prolonged to >20 hours in ESRD.
Renal: approximately 85% of the dose excreted unchanged in urine; biliary/fecal: less than 1%.
Primarily renal (90% or more unchanged via glomerular filtration and tubular secretion); small amounts biliary/fecal (<5%).
