Is cortisone iontophoresis possible?

A Chantraine, J P Ludy, D Berger

    Archives of Physical Medicine and Rehabilitation
    |January 1, 1986
    PubMed
    Summary

    This study investigated steroid iontophoresis for epidermal medication. Findings indicate that corticosteroids do not effectively migrate through the skin using iontophoresis, questioning its therapeutic efficacy.

    Area of Science:

    • Pharmacology
    • Dermatology
    • Physical Chemistry

    Background:

    • Iontophoresis is utilized for epidermal drug delivery, with corticosteroids frequently employed.
    • No prior scientific studies have validated the effectiveness of corticosteroid iontophoresis.
    • This research addresses the lack of evidence regarding steroid penetration via iontophoresis.

    Purpose of the Study:

    • To investigate the transcutaneous migration of corticosteroids using iontophoresis.
    • To evaluate the efficacy of steroid iontophoresis for epidermal medication delivery.
    • To provide scientific evidence on the effectiveness of this drug delivery method.

    Main Methods:

    • Paper electrophoresis was used to determine the electrophoretic mobility of six water-soluble corticosteroids.
    • An in vitro model with human skin separated two solutions under ionization.
    • In vivo studies involved four rabbits and 188 human patients undergoing steroid iontophoresis.

    Main Results:

    • Electrophoretic mobility of tested corticosteroids was characterized.
    • In vitro experiments with a two-cylinder model and human skin showed no steroid migration.
    • In vivo studies in rabbits and patients failed to demonstrate transcutaneous corticosteroid movement.

    Conclusions:

    • The study failed to provide evidence for the transcutaneous migration of corticosteroids via iontophoresis.
    • Results question the effectiveness of steroid iontophoresis as a method for epidermal drug delivery.
    • Further research may be needed to explore alternative methods for effective corticosteroid skin penetration.
