Iontophoresis is useful in laboratory experiments, especially in neuropharmacology. [5] Transmitter molecules naturally pass signals between neurons.By microelectrophoretic techniques, including microiontophoresis, neurotransmitters and other chemical agents can be artificially administered very near living and naturally functioning neurons, the activity of which can be simultaneously recorded.
Iontophoresis is similar to sonophoresis as it is a method for transdermal drug delivery but does so by applying a voltage gradient across the skin. Since there are differences in pathways between iontophoresis and sonophoresis, a combination of these two methods allows for greater enhancement. [ 2 ]
A medical professional administering nose drops Instillation of eye drops. A topical medication is a medication that is applied to a particular place on or in the body. Most often topical medication means application to body surfaces such as the skin or mucous membranes to treat ailments via a large range of classes including creams, foams, gels, lotions, and ointments.

Galvanic treatment in the beauty industry has been described since at least the 1970s [15] and earlier. [13] Sometimes called galvanism, the treatment aims to improve the skin in two ways: (1) cleansing: a process called desincrustation, and (2) nourishing the skin condition, through an electro-chemical process [16] called iontophoresis [17] (also called ionisation). [18]
Sweating is induced by pilocarpine iontophoresis. [3] At the test site, an electrode is placed over gauze containing pilocarpine and electrolyte solution that will not interfere with the sodium and chloride measurement. A second electrode (without pilocarpine) will be placed at another site and a mild electric current will draw the pilocarpine ...
A direct current (DC) incremental voltage under 4 volts is applied on the anode. This DC, through reverse iontophoresis, induces a voltage on the cathode and generates a current (of an intensity less than 0.3 mA) between the anode and the cathode, related to electro-active ions from sweat reacting with the electrodes.
1. Illustration of electrophoresis. 2. Illustration of electrophoresis retardation. Electrophoresis is the motion of charged dispersed particles or dissolved charged molecules relative to a fluid under the influence of a spatially uniform electric field.
Another concern is that incorrectly applied arrays could leave foreign material in the body. Although there is a lower risk of infection associated with microneedles, the arrays are more fragile than a typical hypodermic needle due to their small size and thus have a chance of breaking off and remaining in the skin.
