The available treatments for oral candidosis have proved to be more effi cacious with the use of new and known antifungal drugs. The success of these is directly related to the correct diagnosis, identifi cation, and correction of etiological factors and the commitment of the patient. In the absence of some of these factors, the antifungal therapy results only in a brief relief from disease, triggering relapses. This chapter presents the main drugs used in the treatment of oral and oropharyngeal candidosis, their functioning in the human body, and their mechanism of action in the destruction of the pathogenic agent.
