Amorolfine hydrochloride is the first morpholine antifungal agent useful in the topical
treatment of onychomycosis. Mechanistically, it appears to inhibit two stages of the
ergosterol biosynthetic pathway, which is necessary for fungal cell viability. Active
against a broad spectrum of fungi, amorolfiie hydrochloride is particularly effective
against yeasts such as Histoplasma capsulatum, dermatophytes and dematiaceous fungi.
