Nonwoven fabric membrane for topical use on the skin, comprising polymeric nanofibers and an active agent comprised in an amount from 25 to 80% by weight with respect to the total weight of the nonwoven fabric membrane, wherein a) the active agent is soluble in a suitable biocompatible solvent system, b) the membrane is capable of releasing the active agent immediately when it comes into contact with an amount equal to or greater than 70% of the total weight of the active agent in a period of 30 minutes after contacting the membrane with an appropriate amount of the biocompatible solvent system in which the active agent is completely solubilized, and c) the total content of the active agent is disposed externally to the polymeric nanofibers of the membrane. |
