| Popis: | Bilastine is a non-sedating H1 antihistamine indicated for the treatment of allergic rhinoconjunctivitis and urticaria. The aim of this trial was to assess the bioequivalence of three novel pediatric oral formulations of bilastine. An open label, randomized, four-treatment-period, four-sequence, crossover, single-center study was conducted in 23 healthy volunteers. Each subject received four single doses of bilastine under fasting conditions: a 10-mg orodispersible tablet (DT1), a 10-mg oral solution (SOL), a 10-mg orodispersible tablet without water (DT2dry), and a 10-mg orodispersible tablet with water (DT2water, reference formulation). Blood samples were collected during 72 h with a washout period of at least 7 days. Bilastine maximum plasma concentration (Cmax) and area under the plasma concentration–time curve between 0 to t time (AUC0−t) were calculated to assess bioequivalence. Tolerability was evaluated throughout the study. The three oral pediatric formulations tested were bioequivalent to the reference formulation as determined by the ratio test/reference of the geometric mean and their 90% confidence intervals (between 0.80 and 1.25) for the Cmax, AUC0−t and AUC0−∞. Bilastine was well tolerated when administered indistinctly as an orodispersible tablet or as an oral solution. The three oral pediatric formulations tested were found to be bioequivalent to the reference formulation. All formulations were well tolerated.
