Treprostinil Iontophoresis in Systemic Sclerosis Digital UlcErations. A Proof of Concept Study

Summary

The study is conducted to confirm the good tolerance of a continuous cathodal iontophoresis of the treprostinil hydrogel administered during 10 days on the pulp of the finger of healthy volunteer and on the ischemic digital ulcerations of Systemic Sclerosis patients, particularly to estimate the cutaneous tolerance of the procedure and the effect on the blood pressure.
