Cidofovir

Cidofovir, also known as Vistide™, is a newer anti-viral drug originally developed for a different indication and now appearing to have value in the treatment of laryngeal papillomatosis. It is increasingly used as an adjunctive, off-label treatment for human papillomavirus infection in the larynx – that is, recurrent respiratory papillomatosis (RRP) or laryngeal papillomatosis.
