Treatment of autoimmune disorders with oral interferon

Abstract

Autoimmune disorders are treated by the administration of human interferon, particularly IFN-α or IFN-β, at a dosage of from about 0.01 to about 5 IU/lb./day such that the interferon is held in contact with the patient's oral and pharyngeal mucosae. The interferon is administered in a solid dosage form, e.g., a saliva-dissolvable lozenge.
