Used primarily as an antifungal agent in topical medications, it effectively treats skin infections such as athlete's foot, jock itch, and ringworm. It works by inhibiting fungal cell growth, specifically targeting the synthesis of ergosterol, a key component of fungal cell membranes. Due to its long-lasting activity and ability to penetrate skin layers, it is often preferred for once-daily application. Its formulation in creams and gels allows for localized treatment with minimal systemic absorption, reducing the risk of side effects.
