BACTOCILL vs NALLPEN
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.
NALLPEN (naloxone) is a competitive opioid receptor antagonist that binds to mu, kappa, and delta opioid receptors, reversing the effects of opioid agonists including respiratory depression, sedation, and hypotension.
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
Terminal elimination half-life is 2.0-3.0 hours; prolonged in renal impairment (up to 24 hours).
Renal: 60-70% unchanged; biliary: 20-30% as active metabolite; fecal: 5-10%
Primarily renal excretion (80-90% unchanged) with minor biliary/fecal elimination (5-10%).
