ABSTRACT

OBJECTIVE@#To observe the efficacy of allergen blocking nasal spray (ABNS) , combined with seawater spray (SS) and myrtol standardized capsules (MSS), in patients with rhinitis sicca.@*METHOD@#Patients diagnosed as rhinitis sicca were randomly divided into 2 groups ABNS+SS group and SS group. In ABNS+SS group, patients used ABNS and SS four times per day and MSS twice per day. In SS group, patients used the same medicine except ABNS. Both group were observed for 14 days. The visual analog scale (VAS) of dryness, the endoscopy evaluation score (EES) and the tolerability of the spray were compared between the 2 groups.@*RESULT@#There were 30 patients included in each group. The VAS and EES were improved in both groups after 2 weeks' treatment. The improvement of VAS and EES in ABNS+SS group was significantly superior to SS group (VAS P < 0.01, EES P < 0.05). There were only 2 patients complaint of slight discomfort when using ABNS, which did not disturb the treatment.@*CONCLUSION@#There is good efficacy of allergen blocking nasal spray (ABNS), combined with seawater spray (SS) and myrtol standardized capsules (MSS), in patients with rhinitis sicca.
