BACKGROUND: Lanoconazole (LCZ) is a topical antifungal agent clinically used to treat fungal infections such as tinea pedis. LCZ has not only antifungal effects but also anti-inflammatory effects, which have the potential to provide additional clinical benefits. However, the characteristic features of the inhibitory effects of LCZ on skin inflammation remain unclear.
OBJECTIVE: We evaluated the inhibitory effects of topical application of LCZ, and compared the effects of LCZ with those of other antifungal agents including liranaftate, terbinafine and amorolfine.
METHODS: Each antifungal agent was topically applied on 12-O-tetradecanoylphorbol-13-acetate-induced irritant dermatitis and 2,4,6-trinitrophenyl chloride-induced contact dermatitis in mice (BALB/c). The ear thickness, myeloperoxidase activity and inflammatory mediator contents were evaluated.
RESULTS: LCZ dose-dependently suppressed 12-O-tetradecanoylphorbol-13-acetate-induced irritant dermatitis, suppressed the production of neutrophil chemotactic factors such as keratinocyte-derived chemokine and macrophage inflammatory protein-2, and inhibited neutrophil infiltration to the inflammation site. Moreover, 1% LCZ reduced the ear swelling in mice with 2,4,6-trinitrophenyl chloride-induced contact dermatitis in accordance with the inhibition of interferon-γ production. The inhibitory potency of LCZ on these types of dermatitis in mice was stronger than that of other types of antifungal agents.
CONCLUSION: The anti-inflammatory effects of LCZ were exerted through the inhibition of inflammatory mediator production. These effects may contribute to the relief of dermatitis symptoms in patients with tinea pedis.
