摘要：
The invention concerns a transdermal delivery system for controlled dispensing of an active substance to and through a porous surface. A certain amount of fluid comprising at least one active substance and at least one solvent is dispensed into an administration reservoir. In the administration reservoir the at least one solvent is separated from the administration reservoir by a solvent recovery means such that the active substance achieves a certain level on an interface device which is permeable for the one active substance. Thereby the active substance is absorbable via diffusion from the interface device by a porous surface to be treated.
