Dermoelectroporation®: A New Iontophoresis Concept

From the past.... 
In Iontophoresis  procedures,  it is well known that in order to avoid changes in skin pH, it is necessary to have a two-step procedure.

In the first step, negative ions are introduced into the skin.  In the second step, the polarity is reversed and positive ions are introduced.

At the end of this procedure, the skin pH should be balanced; but some changes in pH may still occur during the treatment, causing skin irritation.

For this reason, it is typically not recommended to perform a microdermabrasion before a traditional Iontophoresis treatment; although  the reduction of the stratum corneum layer, resulting from microdermabrasion, offers faster transdermal drug delivery and higher repeatability. 

 

…To the Future
Mattioli Engineering Labs discovered that by providing a continuous reversed polarity current, controlling the average pulse value, and varying the pulse shape according to the skin’s specific electrical impedance, transdermal delivery of drugs occurs as in classical Iontophoresis, despite the fact that the average current is zero. Moreover macromolecules, like collagen, are transdermally deliverd for the first time ever.

The absence of temporary pH change allows for the use of microdermabrasion before treatment.  Pre-treatment microdermabrasion boosts the transdermal delivery rate and ensures repeatability as a result of the standardization of the thickness and permeability of the stratum corneum.  

The pulse shapes are similar to electroporation pulses, but operate at a much lower energy  and penetrate even under high skin impedance conditions.  For these reasons, Mattioli Engineering named this new patented proprietary technology DERMOELECTROPORATION ®.  

 

University Trials and  Clinical Studies

Studies performed on Dermoelectroporation®by the University of Florence (Italy) labs, evaluated the effects of transdermal delivery of radioactive Lidocaine into the skin.

The study proved that, by using the Dermoelectroporation®  technique,  Lidocaine molecules can be delivered into the dermis after microdermabrasion at a higher rate - applying the same dose - than by using classical Iontophoresis, with no adverse effects.

An exciting new frontier

DERMOELECTROPORATION® technology can be used with approved ionic solutions for Iontophoresis. In addition, the zero average current offers  opportunities for application and use of all types of ionic solutions, due to the absence of electrolytic reactions at the electrodes.
Clinical trials are currently demonstrating the possibility to obtain, for the first time ever, transdermal delivery of macromolecules like collagen; this suggests potential future applications of new types of substances impossible to deliver by classical Iontophoresis.
