NAFCILLIN SODIUM vs PROBAMPACIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nafcillin exerts bactericidal activity by inhibiting bacterial cell wall synthesis via binding to penicillin-binding proteins (PBPs), thereby disrupting peptidoglycan cross-linking. It is resistant to staphylococcal beta-lactamases.
PROBAMPACIN is a synthetic aminoglycoside antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, causing misreading of mRNA and preventing translocation of peptidyl-tRNA from the A-site to the P-site.
1-2 g IV every 4 hours; or 1-2 g IM every 4-6 hours.
100 mg IV every 12 hours over 30 minutes.

Approximately 0.5 hour (30 minutes) in adults with normal renal function; prolonged to 1-2 hours in neonates or severe renal impairment. Clinically relevant for dosing every 4-6 hours.
4.5 hours (prolonged to 12-18 hours in severe renal impairment)
Primarily renal (30-40% unchanged) and hepatic/biliary elimination. Approximately 10-15% excreted in bile via feces.
Renal: 70% unchanged; biliary/fecal: 20% as metabolites; 10% other
