  1. iontophoresis, ionic medication, iontotherapy, electromotive drug administration, EMDA(noun)

    therapy that uses a local electric current to introduce the ions of a medicine into the tissues


  1. iontophoresis(Noun)

    A treatment in which electrodes are put in contact with tissue and a voltage is applied in order to introduce an ionized medication


  1. Iontophoresis

    Iontophoresis, also called electromotive drug administration, is a technique using a small electric charge to deliver a medicine or other chemical through the skin; essentially it is an injection without a needle. The technical description of this process is a non-invasive method of propelling high concentrations of a charged substance, normally a medication or bioactive agent, transdermally by repulsive electromotive force using a small electrical charge applied to an iontophoretic chamber containing a similarly charged active agent and its vehicle. One or two chambers are filled with a solution containing an active ingredient and its solvent, also called the vehicle. The positively charged chamber, called the anode, will repel a positively charged chemical, whereas the negatively charged chamber, called the cathode, will repel a negatively charged chemical into the skin. Iontophoresis is well classified for use in transdermal drug delivery. Unlike transdermal patches, this method relies on active transportation within an electric field. In the presence of an electric field electromigration and electroosmosis are the dominant forces in mass transport. These movements are measured in units of chemical flux, commonly µmol/cm²h.

U.S. National Library of Medicine

  1. Iontophoresis

    Therapeutic introduction of ions of soluble salts into tissues by means of electric current. In medical literature it is commonly used to indicate the process of increasing the penetration of drugs into surface tissues by the application of electric current. It has nothing to do with ION EXCHANGE; AIR IONIZATION nor PHONOPHORESIS, none of which requires current.
