Clinical Observation of Azelastine Combined with Fluticasone in the Treatment of Allergic Rhinitis / 中国药房

ABSTRACT

OBJECTIVE:To observe the effectiveness and safety of azelastine combined with fluticasone in the treatment of allergic rhinitis(AR). METHODS:A total of 135 AR patients were selected from 3 hospitals during Jan. 2015-Jul. 2016, and divided into azelastine group,fluticasone group and drug combination group according to random number table,with 45 cases in each group. On the basis of decongestant Oxymetazoline hydrochloride spray,azelastine group was given Azelastine hydrochloride nasal spray,1 spray each nostril,morning and night;fluticasone group was given Fluticasone propionate nasal spray,1 spray each nostril,morning and night;drug combination was given Azelastine hydrochloride nasal spray combined with Fluticasone propionate nasal spray,with the same usage and dose. Three groups were treated for consecutive 30 d. Total nasal symptom score (TNSS) and total ocular symptom score (TOSS) decline indexes,nasal minimal cross-sectional area (NMCA),total nasal resistance(TNR)and the occurrence of ADR were compared among 3 groups. RESULTS:Some pa-tients were withdrawal from the trial;finally,127 patients were included in full analysis set,and 130 patients were included in safety set. After treatment,TNSS decline index of drug combination group was significantly higher than azelastine group and fluticasone group,with statistical significance(P0.05). Before treatment, 3 groups suffered from nasal ventilation disorder to different extents,but there was no statistical significance in TNR or NMCA among 3 groups(P>0.05). After treatment,NMCA and TNR at 75,150 Pa of 3 groups were significantly lower than before,and TNR of drug combination group was significantly lower than azelastine group and fluticasone group,with statisti-cal significance(P0.05). There was no statistical significance in the incidence of ADR among 3 groups(P>0.05). CONCLUSIONS:Both azelastine and fluticasone can effec-tively relieve nasal symptom as well as improve nasal ventilation disorder in AR patients;therapeutic efficacy of drug combi-nation is better than single drug,and it doesn't increase the incidence of ADR.
