POLYMOX vs PROBAMPACIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Amoxicillin is a bactericidal antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs) and inhibiting transpeptidase activity, leading to cell lysis.
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.
250-500 mg orally every 8 hours or 500-875 mg orally every 12 hours; maximum 4 g/day.
