摘要： A reservoir electrode assembly of the present invention for an iontophoretic drug delivery device includes an electrode and a hydrophilic reservoir situated in electrically conductive relation to the electrode. The hydrophilic reservoir is formed from a bibulous hydrophilic cross-linked polymeric material having a first surface and a second surface that is adhesively adherent to the electrode. The first surface of the polymeric material is releasably adhesively adherent when applied to an area of a patient's skin. The polymeric material has a cohesive strength forms an adhesive bond with a bond strength between the second surface of the polymeric material to the electrode that is greater than the cohesive strength of the polymeric material. Additionally, an adhesive bond strength of the first surface of the polymeric material to the applied area of the patient is less than the cohesive strength of the polymeric material so that upon removal of the reservoir assembly of the invention from the applied area of the patient, substantially no polymeric material remains on the applied area and the hydrophilic reservoir remains substantially intact and adhesively adherent to the electrode.

摘要： A method for testing the ability of an iontophoretic reservoir-electrode to deliver a medicament includes providing an iontophoretic reservoir-electrode with a contact surface having a shape, a suitable electrical connection and a hydrated bibulous reservoir containing an ionized medicament. The method further includes providing another electrode operating a at preselected polarity opposite to the preselected polarity of the medicament reservoir-electrode. The method further includes providing a separation medium having the property of allowing passage therein to of ions of one charge. The separation medium is positioned between the reservoir electrode with the ionized medicament and the another electrode. The method also includes applying a sufficient electrical potential between the iontophoretic reservoir-electrode containing the ionized medicament and the another iontophoretic reservoir-electrode so that a current flows through the separation medium for a preselected time thereby transporting a quantity of the ionized medicament into the separation medium. The method then includes determining an amount of the ionizable medicament in the separation medium.
