Summary:The present invention relates to methods for conducting controlled environment electrotransport. The methods generally concern control of the ionic environment of the active electrode reservoir, in an electrotransport system. This control may be utilized, for example, to maintain a constant extraneous ion presence, such as pH. It may also be applied in a preferred manner to maintain selected control over the delivery rate of a target species, in time, in the presence of extraneous ions. The present invention also relates to an apparatus that provides electrotransport in a controlled environment. In general the apparatus comprises an electrotransport system including an active electrode reservoir having therein a primary electrode arrangement and a secondary electrode arrangement, with a control arrangement for the selected operation of both. The secondary electrode arrangement, being operated differently from the primary electrode arrangement, is selected for operation to selectively enhance or otherwise modify ion presence in the active electrode reservoir, to achieve application of the general methods described. The apparatus may include a sensor, which will act as feedback to a control system during operation. The present invention also relates to methods and systems involving diffusion type delivery.
