A transdermal system (1) for the administration of at least two substances through the skin with the aid of an electric current has a reservoir, which comprises a storage layer (2) for the substances, and a transfer means, which may be arranged in the form of a separating layer (3), that is connected to both the reservoir and the patient's skin (5) during administration. The transdermal system also has electrodes (4) which generate a current that transports the substances from the reservoir into the skin (5). In the transdermal system (1) means for the physical separation of the substances are provided that render possible a sequential administration of the substances.
