1. A pharmaceutical reservoir electrode for use in iontotherapeutic delivery of a pharmaceutical which is ionized and is contained therein, comprising:

  • a) a housing for said electrode;

    b) a first chamber which contains an electrolytic solution to permit said iontotherapeutic delivery to take place and having present therein ion exchange granules which inhibit increased ionic content through ion generation in the electrode in the first chamber as the iontotherapeutic process takes place;

    c) an electrical terminus to contact electrically the electrolytic solution contained in said first chamber;

    d) a second chamber for receiving a unit dose of said ionized pharmaceutical, ande) a permselective membrane separating said first and second chambers, said membrane characterized by having pores with sufficiently low permeability to inhibit substantial passage of said ionized pharmaceutical present in said second chamber into said first chamber, said permselective membrane being substantially free of ion exchange sites.
