Insights
Pediatric formulation acceptability in Japan showed minor differences compared to Europe, with powders being more favored. These findings are crucial for developing globally appropriate pediatric drug formulations.
Area of Science:
- Pharmaceutical Sciences
- Pediatric Medicine
- Drug Development
Background:
- Global challenge in developing suitable pediatric drug formulations.
- Urgent need for acceptability data to guide the creation of standard pediatric dosage forms.
- Lack of age-appropriate formulations hinders effective pediatric treatment worldwide.
Purpose of the Study:
- Assess the acceptability of various oral dosage forms among pediatric patients in Japan.
- Gather insights into age-appropriate pediatric formulations to support global drug development.
- Compare perceptions of oral formulation acceptability between community and hospital settings.
Main Methods:
- Cross-sectional observational study involving caregivers and nursing staff.
- Face-to-face interviews conducted in community pharmacies and a pediatric hospital.
- Questionnaire assessed acceptability of tablets, capsules, powders, liquids, and orally disintegrating tablets by age.
Main Results:
- Acceptability of oral dosage forms in Japan aligned closely with European guidelines.
- Perceptions of powder formulation acceptability differed between community and hospital settings.
- Hospital nursing staff found powder formulations acceptable from the neonatal period.
Conclusions:
- Caregiver perceptions of oral formulation acceptability in Japan showed minimal divergence from European data.
- Powder dosage forms were perceived as more acceptable in the Japanese context.
- Further global intervention studies are recommended to determine worldwide pediatric formulation preferences.
Background:
The lack of appropriate pediatric formulations is a global issue and information on acceptability is urgently needed to develop standard pediatric formulations. This study aimed to assess perceptions of acceptability of several oral dosage forms among pediatric patients at a community and a pediatric hospital in Japan and collected information about age-appropriate pediatric formulations, aiming to contribute to drug development promotion worldwide.
Methods:
A cross-sectional observational study was performed. A convenience sample of caregivers was recruited from available chain-owned retail pharmacies and inpatient pediatric units. The questionnaire was composed of 3 parts: (1) acceptability of the 5 dosage forms (tablets, capsules, powders, liquids, and orally disintegrating tablet) by age; (2) acceptability of dosage size, amount, and volume by age; and (3) the actual method of administration. Face-to-face interviews were conducted at 3 independent community pharmacies (324 parents) and tertiary care pediatric hospital wards (112 nursing staff). Acceptability scores and acceptable dosages were then determined. The survey was conducted from October 1 to December 1, 2017, for the hospital setting and November 1 to 30, 2017, for the outpatient setting.
Results:
The acceptability of oral dosage forms was roughly similar to the matrix drafted by the European Medical Agency. Differences in perception of the powder forms between communities and hospitals were also observed, with the nursing staff perceiving powder as being acceptable from the neonatal period.
Conclusions:
The difference in caregivers' perception of the acceptability of oral formulations between Japan and Europe was small. The powder form was found to be more acceptable in Japan. Further intervention studies are needed to assess the preferred pediatric formulation worldwide.
