iontophoresis

Therapeutics A type of transcutaneous drug delivery in which electric current is applied to the skin to enhance absorption of large polar or hydrophilic molecules and peptides–eg, insulin, and control therapeutic delivery. See Transcutaneous drug delivery. Cf Phonophoresis.

iontophoresis (īon´tōfôrē´sis),

n the application, by means of an appropriate electrode, of a galvanic current to an ionizable agent in contact with a surface to hasten the movement into the tissue of the ion of opposite charge to that of the electrode. See also ionization.

Therefore, iontophoresis was chosen for this study based on three major advantages over passive diffusion: (1) control of penetration can be linked to drug flux by the magnitude of the electrical current; (2) lag times are reduced or removed, making drug action more rapid; and (3) time of administration can be controlled by removal of the iontophoresis patch, which cannot be easily accomplished by topical formulations.
