Summary

The lack of appropriate pediatric formulations compromises adherence and the effectiveness of oral treatment in children, mainly due to the splitting of adult tablets and low sensory acceptability. This observational, analytical, and cross-sectional study aims to evaluate the acceptability of a novel pediatric dosage form consisting of placebo chewable tablets produced by 3D printing, with a focus on palatability and feasibility for dose personalization. Children and adolescents aged 3 to 18 years receiving care at the Nutrition Outpatient Clinic of the Hospital da Criança de Brasília José Alencar will be invited to participate. The study will be conducted in two stages. In the first stage, acceptability of a bear-shaped chewable tablet will be assessed, as well as preference among different flavors. In the second stage, preference for chewable tablets with or without xylitol will be investigated, in addition to dysgeusia associated with diseases or chronic medication use. Acceptability will be measured using a 5-point facial hedonic scale, evaluator observation, and age-appropriate questionnaires. The study is expected to identify the most accepted flavors and sweetness intensities, as well as to evaluate the acceptability of the 3D-printed dosage form, contributing to the development of safer, more attractive, and personalized pediatric medicines.
