ABSTRACT:
An electrotransport apparatus using dispersed ion exchange material (19,93) is disclosed. The ion exchange material (19,93) may be dispersed in either the donor electrode assembly (10), the counter electrode assembly (10) or both electrode assemblies. The dispersed ion exchange material (93) comprises mobile ionic species (C2) and substantially immobile ionic species (P). The dispersed ion exchange material (93) is consumed during electrotransport of drug or agent (A) in an electrotransport process in which substantially no species which compete with the drug or agent for electrotransport are generated. Electrotransport devices exhibiting reduced polarization are also disclosed.
