New Patents of Fixed Combinations of Nasal Antihistamines and Corticosteroids in Allergic Rhinitis

Author(s): Ole D. Wolthers

 

Abstract: During the last few years, fixed combinations of intranasal antihistamines and corticosteroids have been introduced for treatment of allergic rhinitis. The aim of this systematic review was to assess recent patents and clinical evidence for fixed combinations of intranasal antihistamines and intranasal corticosteroids in allergic rhinitis. Data base searches revealed that intranasal combinations of the antihistamine azelastine with the corticosteroids mometasone furoate, ciclesonide and fluticasone propionate, respectively, have been patented. Four randomized, double-blinded, parallelgroup, placebo-controlled, multicenter trials sponsored by the manufacturer evaluated the fixed combination of intranasal azelastine 125µg and fluticasone propionate 50µg administered as one dose per nostril b.i.d. in patients with moderate-tosevere symptomatic allergic rhinitis ≥ 12 years of age. Three of the studies were published as a meta-analysis which found the fixed combination of azelastine and fluticasone propionate statistically significantly more efficacious in reducing baseline total nasal symptom score by 5.7 as compared to azelastine (4.4; P < 0.001), fluticasone propionate (5.1; P < 0.001) and placebo (3.0; P < 0.001). The findings were supported by secondary assessments of scores of specific nasal and ocular symptoms.
