BACTOCILL vs SPECTROBID
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.
Spectrobird (bacampicillin) is a prodrug of ampicillin, a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
250-500 mg orally every 6 hours or 1-2 g intravenously every 4-6 hours
400 mg orally twice daily or 200 mg orally four times daily for 10-14 days. For acute exacerbations of chronic bronchitis: 400 mg orally twice daily for 10 days.
