Mechanism of action

Neomycin works by irreversibly binding to the bacterial 30S ribosomal subunit, disrupting the translation of mRNA into proteins and ultimately causing bacterial cell death. As an oral formulation, it is poorly absorbed from the gastrointestinal tract and acts locally within the gut, making it useful for reducing intestinal bacterial flora. This mechanism makes it effective for pre-operative bowel sterilization and treatment of certain gastrointestinal infections.
