Abstract:
A method for testing the ability of an iontophoretic reservoir-electrode to deliver a medicament, the method comprising:providing an iontophoretic reservoir-electrode having a contact surface, said iontophoretic reservoir-electrode including an electrical connection and a reservoir including an ionized medicament; providing another electrode; providing a separation medium having the property of allowing a transport of an amount thereinto of said ionized medicament under the influence of an applied electric current flowing therethrough compared to a transport of an amount of said ionized medicament thereinto in the absence of said applied electric current in a ratio greater than one; placing said contact surface of said iontophoretic reservoir-electrode including said ionized medicament in electrical contact with said separation medium; placing said separation medium in electrical contact with said another electrode; applying a sufficient electrical potential between said iontophoretic reservoir-electrode including said ionized medicament and said another electrode so that a preselected current flows through said separation medium for a preselected time thereby transporting at least a portion of said ionized medicament into said separation medium; and determining an amount of said ionized medicament in said separation medium.
