Used primarily as an antifungal agent in the treatment of dermatological infections such as athlete's foot, jock itch, and ringworm. It is effective against a broad spectrum of fungi including dermatophytes, yeasts, and molds. Commonly formulated in creams, sprays, and powders for topical application. Its mechanism involves inhibition of ergosterol synthesis, disrupting fungal cell membrane integrity. Also found in some nail lacquers for onychomycosis treatment due to its keratin affinity and deep tissue penetration.
