Frequently Asked Questions about Amorolfine

**Q: What is the mechanism of action of Amorolfine?** A: Amorolfine works by inhibiting the enzyme sterol 14α-demethylase, which is crucial for ergosterol biosynthesis in fungal cell membranes. This disruption in ergosterol production leads to the accumulation of toxic sterol precursors, ultimately causing fungal cell death.

**Q: What are the common formulations of Amorolfine?** A: Amorolfine is commonly available as a 5% nail lacquer and a 0.25% cream for topical application. The nail lacquer is primarily used for treating fungal nail infections (onychomycosis).

**Q: Is Amorolfine approved for use in the United States?** A: No, Amorolfine is not currently approved by the FDA for use in the United States. It is, however, available in many European countries and Japan for the treatment of fungal infections.

**Q: What types of fungal infections can Amorolfine treat?** A: Amorolfine is effective against various fungal infections, particularly those caused by dermatophytes and Candida species. It is most commonly used to treat onychomycosis (fungal nail infections) and some superficial skin infections.
