Abstract
The hydrophilic penetration agents customarily used for the transcutaneous penetration of active ingredients are, surprisingly, found to improve the penetration of antifungal agents through the nails. A corresponding dermatological composition contains at least one antifungal agent chosen, in particular, from among those of the allylamine family, such as terbinafine-HCl and naftifine-HCl; at least one hydrophilic penetration agent chosen, in particular, from among the glycols, glycol monoethers, glycol diethers, dimethylsulphoxide, caprolactam, dimethylisosorbide, isopropylidene glycerol, dimethylimidazolidinone, ethyl lactate, the polyoxyethylenated C.sub.8 -C.sub.10 glycerides, polyethylene glycol 20 glyceryl laurate and dimethylacetamide; and a water-alcohol solvent medium which dissolves the said antifungal agent(s) and in which the said penetration agent(s) is (or are) at least partially miscible.
