Brief Summary

To assess the effect and safety of sublingual Dermatophagoides Farinae Drops in adult patients with atopic dermatitis and allergic sensitization to house dust mites.240 adults age 18 to 60 years with atopic dermatitis(Objective Scoring Atopic Dermatitis, Objective SCORAD from 10 to 40) are going to be enrolled in a randomized,double-blind,placebo-controlled study.Sublingual Dermatophagoides Farinae Drops or placebo is given for 9 months in addition to standard therapy.SCORAD,average anesis interval,rescue medicine and DLQI will be recorded.
