Paromomycin is a broad spectrum aminoglycoside antibiotic produced by Streptomyces rimosus var. paromomycinus. The in vitro and in vivo antibacterial action of paromomycin closely parallels that of neomycin.
- Mechanism of action
Paromomycin inhibits protein synthesis by binding to 16S ribosomal RNA. Bacterial proteins are synthesized by ribosomal RNA complexes which are composed of 2 subunits, a large subunit (50s) and small (30s) subunit, which forms a 70s ribosomal subunit. tRNA binds to the top of this ribosomal structure. Paramomycin binds to the A site, which causes defective polypeptide chains to be produced. Continuous production of defective proteins eventually leads to bacterial death.
Target Actions Organism A30S ribosomal protein S10 inhibitorThermus thermophilus (strain HB8 / ATCC 27634 / DSM 579) A16S ribosomal RNA inhibitorEnteric bacteria and other eubacteria - Absorption
Poorly absorbed after oral administration, with almost 100% of the drug recoverable in the stool.
