Antifungal agents used for deep-seated mycotic infections.

The main antifungal agents used for deep-seated mycotic infections are the broad-spectrum antifungal drug amphotericin B, the narrow-spectrum agent flucytosine, and the newer broad-spectrum agents miconazole and ketoconazole. Amphotericin B remains the cornerstone of antifungal therapy. For the treatment of cryptococcal meningitis, the current recommendation is for the combined use of amphotericin B and flucytosine. 2-Hydroxystilbamidine is used only in indolent cases of blastomycosis; however, this condition is usually treated with amphotericin B. Clinical experience with the newer agents is limited. Not all patients from whom fungal agents have been isolated require treatment; the extent of the fungal infection should be determined, when possible, for evaluation of the need for treatment.
