Bilastine for the treatment of allergic rhinoconjunctivitis and urticaria: results from an international Delphi study

Abstract

Background: Second-generation oral H1-antihistamines, including bilastine, represent the emerging treatments of allergic rhinitis (including rhinoconjunctivitis) and chronic urticaria in both adults and children. This study analyses available evidence supporting the use of bilastine amongst second-generation antihistamines for the symptomatic treatment of allergic rhinitis and urticaria in adults and children. Methods: Consensus amongst experts from 17 countries on the ideal treatment of rhinitis and urticaria, and the specific role of bilastine was measured by means of a modified Delphi process. A total of 12 statements were voted on by the experts using a five-point Likert scale (1 = strongly disagree; 2 = disagree; 3 = undecided; 4 = agree; 5 = strongly agree). The definition of consensus was set at a minimum of 80% concordance for 4+5 scores (agree or strongly agree). Results: All proposed statements reached consensus, with a concordance of ≥98% for five statements and ≥96% for seven. Conclusions: The wide consensus obtained for the proposed statements suggests a prominent role for bilastine in the management of allergic rhinitis and urticaria.
