New insights into the effect of amorolfine nail lacquer.
Despite improvements in antifungal strategies, the outcome of treating onychomycoses often remains uncertain. Several factors account for treatment failure, of which the pharmacokinetics and pharmacodynamics of the antifungal are of importance. The taxonomic nature and ungual location of the fungus cannot be neglected, besides the type of nail and its growth rate. In addition, the biological cycle of the fungus and the metabolic activity of the pathogen likely play a marked influence in drug response. The presence of natural antimicrobial peptides in the nail is also probably a key feature controlling the cure rates. There are many outstanding publications that cover the full spectrum of the field. The purpose of this review is to put in perspective some facets of activity of the topical treatment using amorolfine nail laquer. The antifungal activity of the drug is likely less pronounced in onychomycosis than that expected from conventional in vitro studies. However, the nail laquer formulation should reduce the propensity to form antifungal-resistant spores and limit the risk of reinfection.
