Used primarily in the treatment of fungal skin infections such as athlete’s foot, jock itch, and ringworm. It works by inhibiting the synthesis of ergosterol, a vital component of fungal cell membranes, leading to cell death. Due to its potent antifungal activity and long residence time in the skin, it is effective with once-daily application. Commonly formulated in creams and lotions for topical use, it shows efficacy against dermatophytes, yeasts, and molds. Its strong skin penetration allows for shorter treatment durations compared to other antifungals.
