Pharmacologic Category

Synthetic, broad-spectrum antifungal agent in the allylamine class; appears to have both fungistatic and fungicidal activity. Exhibits antifungal activity by selectively inhibiting the enzyme squalene epoxidase in a dose-dependent manner which results in a reduced synthesis of ergosterol, the primary sterol within the fungal membrane, and increased squalene in cells.
