Iontophoresis potentially may be a good alternative to improved delivery of corticosteroids.
Study Investigators propose to use iontophoresis to increase dexamethasone delivery into
thick psoriasis plaques. The primary purpose of this study is to assess whether dexamethasone
sodium phosphate iontophoresis is an effective local therapy for psoriasis. The objective of
the study is to determine the efficacy of dexamethasone sodium phosphate iontophoresis for
psoriasis.
