What Is It?

• Active ingredient: Ciclopirox, an antifungal agent that works by binding to the cell membrane of fungi and inhibiting the production of ergosterol, a key component of fungal cell walls.
• Formulation: Cream, gel, or suspension (the “suspension” form is typically a finely dispersed powder in a liquid base, making it easy to apply to irregularly shaped skin or nail surfaces).
