Naphthyfine is an antifungal agent for external use that belongs to the class allylamines. The mechanism of action is associated with the inhibition of squalene-2,3-epoxidase, which leads to a decrease in the formation of ergosterol, which is part of the cell wall of the fungus.
Active against dermatophytes, such as Trichophyton, Epidermophyton, Microsporum, molds (Aspergillus spp.), yeast fungi (Candida spp., Pityrosporum) and other fungi (for example, Sporothrix schenckii). For dermatophytes and aspergillas naphthyline is fungicidal. Regarding yeast fungi naphthyline shows fungicidal or fungistatic activity, depending on the strain of the microorganism.
Has antibacterial activity against Gram-positive and Gram-negative microorganisms, which can cause secondary bacterial infections.
Has an anti-inflammatory effect, which contributes to the rapid disappearance of symptoms of inflammation, especially itching.
