New antifungal agents.

This article, rather than presenting an overview of all available antifungal agents, has provided an update on new information about older agents, as well as evolving information about new agents, including those currently undergoing clinical trials. Among the azoles, ketoconazole will continue to be used as a major antifungal agent in dermatology, but one must keep up with its side effects and drug interactions. The place of the new triazole fluconazole in the treatment of cutaneous fungal infections needs to be clarified by additional controlled studies. Other agents on the horizon which are still undergoing investigation include itraconazole, which should be especially useful for dermatophyte (including tinea unguium) and candidal infections, sporotrichosis, and unusual infections such as aspergillosis and phaeohyphomycosis; and terbinafine, a member of the new class of antifungals called allylamines, which is an orally and topically active fungicidal agent that should be very useful for all types of dermatophyte infections. Research continues into the effectiveness of members of other classes of antifungals, including piritetrate, cilofungin, and amorolfine. In the 1990s, dermatologists should have safer, more effective antifungal agents for treating cutaneous fungal infections.
