[Naftifin--laboratory and clinical experience with a new antimycotic from the allylamine group]

The authors evaluated the effectiveness of naftifin on a broad spectrum of 42 types of agents causing mycoses. Using the microdilution method, the authors assessed minimal inhibiting concentrations (MIC) of this antimycotic agent in 107 clinical isolates. Naftifin displayed a selective antifungal activity: excellent sensitivity was found in dermatophytes (MIC 90% = 0.39 mg.l-1), Aspergillae were medium sensitive (MIC = 0.09-12.5 mg.l-1). The majority of yeasts and filamentous fungi from the group of Zygomycetes was resistant to naftifin. The therapeutic results in 57 subjects with dermatomycoses corresponded to the results of in vitro tests of the antimycotic agent. Most successful as treatment of dermatophytoses at extra-intertriginous sites and treatment of pityriasis versicolor; manifestation of candidoses were not affected. The commercial preparation used--Fetimin cream--is considered by the authors a suitable alternative of hitherto used local antimycotics, in particular preparations from the azole series.
