Swallowability of Minitablets among Children Aged 6-23 Months: An Exploratory, Randomized Crossover Study

Minitablets have garnered interest as a new paediatric formulation that is easier to swallow than liquid formulations. In Japan, besides the latter, fine granules are frequently used for children. We examined the swallowability of multiple drug-free minitablets and compared it with that of fine granules and liquid formulations in 40 children of two age groups (n = 20 each, aged 6-11 and 12-23 months). We compared the percentage of children who could swallow minitablets without chewing with that of children who could swallow fine granules or liquid formulations without leftover. The children who visited the paediatric department of Showa University Hospital were enrolled. Their caregivers were allowed to choose the administration method. In total, 37 out of 40 caregivers dispersed the fine granules in water. Significantly more children (80%, 95% CI: 56-94%) aged 6-11 months could swallow the minitablets than those who could swallow all the dispersed fine granules and liquid formulations (22%, 95% CI: 6-47% and 35%, 95% CI: 15-59%, respectively). No significant differences were observed in children aged 12-23 months. Hence, minitablets may be easier to swallow than dispersed fine granules and liquid formulations in children aged 6-11 months.
