What is vancomycin-oral, and how does it work (mechanism of action)?

Oral vancomycin is a glycopeptide antibiotic that is used for the treatment of Clostridium difficile diarrhea and staphylococcal enterocolitis. Vancomycin is a bactericidal antibiotic (it kills bacteria) that exerts its effects by preventing bacteria from forming cell walls, which they need to survive. Vancomycin is only effective against gram-positive bacteria.

Oral vancomycin is poorly absorbed, and ingestion does not result in significant levels of drug in the body. Therefore, oral vancomycin is limited to the treatment of infections that are limited to the gastrointestinal tract such as diarrhea that is associated with the overgrowth of C. difficile.

Vancomycin is excreted in human milk after intravenous administration. However, oral administration of vancomycin does not result in significant levels of drug in the blood, and it is not known if vancomycin is excreted in breast milk after oral administration.
