“…These drugs include alkylating agents such as cyclophosphamide [8,12], folic acid antagonists such as methotrexate [10,13,14,16,17,21], and purine analogues such as azathioprine [2, 3, 6, 7, 10, 11, 18-20, 25, 27], There is little doubt that these immunosuppressive agents usually have a beneficial effect in the treatment of pemphigus and pemphigoid. Most authors recommend the combined administration of a corticosteroid and an immuno suppressive drug, the latter permitting a significant reduction in steroid dosage.…”
