Abstract
The iontophoresis device for transcutaneous administration of the active principle to the subject comprises electrodes, at least one of which is a consumable electrode formed of an electrochemically consumable material associated either with an insulating support or with a particular electronically conducting support. The single consumable electrode or one of the consumable electrodes holds a limited quantity of electrochemically consumable material, the said limited quantity being chosen so that the quantity of electricity necessary for its electrochemical consumption corresponds to the quantity of electricity necessary for administering the given total quantity of active principle to the subject and the active principle is present at the start of the operation in a quantity greater than the said given total quantity.
