Amorolfine hydrochloride is primarily used as an antifungal agent, particularly in the treatment of fungal infections of the nails and skin. It is commonly applied topically in the form of creams, gels, or nail lacquers to treat conditions such as onychomycosis (fungal nail infections) and cutaneous mycosis (fungal skin infections). The compound works by inhibiting the synthesis of ergosterol, an essential component of fungal cell membranes, thereby disrupting their growth and leading to their eventual death. Its effectiveness against a broad spectrum of fungi, including dermatophytes, yeasts, and molds, makes it a versatile option for managing fungal infections. Regular application is recommended for optimal results, especially in nail infections, which may require prolonged treatment due to the slow growth of healthy nails.
