Abstract
Bilastine, a second-generation antihistamine, is approved in Europe for the treatment of allergic rhinoconjunctivitis and urticaria in adults and children aged ≥ 6 years. Pharmacokinetic data for children aged 6–11 years were extracted post hoc from a study in which children (2–11 years) with allergic rhinoconjunctivitis or urticaria received oral bilastine (10 mg/day). Maximum plasma concentration (Cmax) and area under the plasma concentration curve (AUC) data were compared with adult pharmacokinetic data from seven clinical studies (bilastine 20 mg/day). Safety data for children aged 6–11 years were extracted post hoc from a phase III randomized controlled trial of children (2–11 years) with allergic rhinoconjunctivitis or chronic urticaria receiving once-daily bilastine 10 mg or placebo for 12 weeks. Exposure and Cmax values were similar for children (6–11 years) and adults: median pediatric/adult ratios for AUC0–24 and Cmax were 0.93 and 0.91, respectively. There was no significant difference in the incidence of treatment-emergent adverse in children (6–11 years) receiving bilastine 10 mg or placebo.Conclusion: Pharmacokinetic and safety analyses in children aged 6–11 years support the suitability of the pediatric dose of bilastine 10 mg and confirm that the safety profiles of bilastine and placebo are similar.What is Known:• Bilastine, a second-generation antihistamine, is approved in Europe for the treatment of allergic rhinoconjunctivitis and urticaria in adults (20 mg/day) and children aged ≥ 6 years (10 mg/day).• An ontogenic model based on adult data and pharmacokinetic/pharmacodynamic simulations supported the selection of a bilastine dose of 10 mg/day in children aged 2–11 years. Bilastine 10 mg/day was shown to have a safety profile similar to that of placebo in a large phase III randomized clinical trial in children aged 2–11 years.What is New:• As bilastine is approved in Europe for children aged ≥6 years, the current study reports the results of two post hoc analyses of pharmacokinetic and safety data in children aged 6–11 years.• Analysis of pharmacokinetic and safety data in children aged 6–11 years supports the suitability of the pediatric dose of bilastine 10 mg and confirms that its safety profile is similar to that of placebo.
Highlights
Bilastine is a second-generation non-sedating and non-brain penetrating antihistamine which is approved in Europe for the treatment of allergic rhinoconjunctivitis and urticaria in adults and children aged ≥ 6 years with a body weight ≥ 20 kg [1,2,3,4,5,6]

Summary
Bilastine is a second-generation non-sedating and non-brain penetrating antihistamine which is approved in Europe for the treatment of allergic rhinoconjunctivitis and urticaria in adults and children aged ≥ 6 years with a body weight ≥ 20 kg [1,2,3,4,5,6]. As bilastine is approved in Europe for children aged 6 years or over, the current study reports the results of two post hoc analyses of PK and safety data. A post hoc analysis of safety data in the same age group was conducted These data were obtained from a phase III, placebo-controlled, randomized, controlled trial of bilastine 10 mg/day for the treatment of children with allergic rhinoconjunctivitis or chronic urticaria [5]
