| Outline of Final Research Achievements |
Topical glucocorticoids are the first-line therapy for chronic dermatitis. We previously reported that long-term topical glucocorticoids exacerbated pruritus in chronic dermatitis model mice. In this study, we clarified that oral dose of histamine H4 receptor antagonist prevented the worsening of pruritus, and additionally suppressed the inflammation. These results indicated that H4 receptor antagonist would be useful for prevention of the exacerbation of pruritus induced by topical glucocorticoids in patients with chronic dermatitis.
