Active Iontophoresis
One active iontophoresis patch will be applied once at the baseline clinical visit. The iontophoresis patches are called Activapatch intellidose 2.5.
Activapatch intellidose 2.5 using active Iontophoresis
Iontophoresis is a drug delivery system that uses electromigration and electro-osmosis to move charged molecules. Electromigration is the movement of ions across the skin by an electrical field. Positive ions move away from a cathode (positive charge) and towards an anode (negative charge). Negative ions move away from an anode and towards a cathode. Electro-osmosis is the volume movement of positive ions away from the opposite charge. Since skin is negatively charge, positively charged ions penetrate deep in the tissue from the negatively charged skin. 4 The use of iontophoresis was incorporated into medicine in efforts to increase the penetration of medications and avoid injection procedures. Dexamethasone sodium phosphate 4 mg/mL vial will be used in the study. Using a syringe, 2 cc of dexamethasone will be drawn and poured onto the designated medication site on the iontophoresis patch. Once the medication is poured, the patch will be applied on the skin and turned on.
Dexamethasone
Dexamethasone sodium phosphate 4 mg/mL vial will be used in the study. Using a syringe, 2 cc of dexamethasone will be drawn and poured onto the designated medication site on the iontophoresis patch. Once the medication is poured, the patch will be applied on the skin and turned on.
Inactive Iontophoresis
One inactive iontophoresis patch will be applied once at the baseline clinical visit. The iontophoresis patches are called Activapatch intellidose 2.5.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Subjects with diagnosed plaque-type psoriasis that is stable.
* Similar psoriasis plaques found on each limb and/or different sides of the trunk.
* Willingness to attend all scheduled visits and complete the study.
* Ability to understand and sign an informed consent form.
Exclusion Criteria
* Change in the use of systemic therapy in psoriasis within 4 weeks prior to applying iontophoresis patches (to allow time for washout).
* Use of topical therapy (including coal tar, salicylic acid, topical corticosteroids, vitamin D, vitamin A, urea) or recent phototherapy for psoriasis within 2 weeks prior to applying iontophoresis patches (to allow time for washout).
* Pregnancy or breast feeding women.
* Any other condition, in the judgement of the investigator, would put the subject at unacceptable risk to participate.
