We report twelve cases receiving on oral therapy of DDS. 9 patients with pemphigus and pemphigoid, which were resistant to systemic corticosteroid therapy and reduction of corticosteroid therapy, were treated orally with DDS (50∼75 mg/day). No side effects were found in the safety assessment except for case No. 5 due to misuse (150 mg/day) for a week. The rate of improvement in this study was 75% (9/12).
