The Effect of Capsaicin Spray in Nasal Hyperreactivity

ABSTRACT

Capsaicin, a nonenamide derived from Capsicum plants, has proven to be useful in patients with vasomotor rhintitis. In this study, we estimated the effects of 10-5 M capsaicin spray in patients with hypersensitive rhinitis. The drug was given 3 times per day for 3 days to each patient by means of a spray delivered to the nasal mucosa. Patient's symptom score was recorded by the same physician. We repeated this method after 1 week, 2 week, 4week, 8week, 12week, 16week and recorded their symptom score. As a result, the mean symptom score involving nasal obstruction, sneezing, rhinorrhea and itching was remarkably reduced by capsaicin spray. The present findings suggest that capsacine spray is a good therpheutic method for hypersensitive rhinitis patients.
