PROBAMPACIN vs PROSTAPHLIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Prostaphlin (oxacillin) is a penicillinase-resistant penicillin that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically PBP1 and PBP3, leading to inhibition of transpeptidation and cell lysis. It is resistant to staphylococcal beta-lactamases.
100 mg IV every 12 hours over 30 minutes.
250-500 mg IM or IV every 4-6 hours for moderate to severe infections. For oral use: 250-500 mg every 6 hours on empty stomach.
