An iontophoresis device includes active and counter electrode assemblies.
The active electrode assembly includes an active electrode element and at
least two laterally spaced active agent reservoirs. The active electrode
assembly may also include an outermost ion selective membrane caching an
active agent and a further active agent carried by an outer surface of
the outermost ion selective membrane. The active electrode assembly may
also include an electrolyte reservoir storing electrolyte and an inner
ion selective membrane positioned between the electrolyte reservoir and
the active agents. The active electrode may also include an inner
withdrawable sealing liner between the electrolyte reservoir and the
active agents. An outer release liner may protectively cover or overlay
the further active agent and/or outer surface prior to use. The active
electrode assembly may also include a blister pack of at least two
hydrating agent blisters to selectively hydrate dehydrated active agent.
