BACTOCILL vs VEETIDS '250'
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
BACTOCILL (nafcillin) is a penicillinase-resistant penicillin that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting transpeptidation and autolysin inhibitors. Active against Staphylococcus aureus and other gram-positive bacteria.
VEETIDS '250' is an oral cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), particularly PBP-3, thereby disrupting peptidoglycan cross-linking and leading to cell lysis.
250-500 mg orally every 6 hours or 1-2 g intravenously every 4-6 hours

0.5-0.8 hours; prolonged to 2-4 hours in severe renal impairment
2-3 hours in adults with normal renal function; prolonged to 24-40 hours in anuria/end-stage renal disease, requiring dose adjustment.
Renal: 60-70% unchanged; biliary: 20-30% as active metabolite; fecal: 5-10%
Primarily renal (≥90% as unchanged drug) via glomerular filtration and tubular secretion; minor biliary/fecal (<5%).
