Introduction: Potentially harmful excipients (PHEs) for children have been reported and the need for information collection has been advocated. However, studies on the actual occurrence of adverse events are limited. This study investigated the quantitative exposure of PHEs via injection and their association with adverse events in children under 2 years of age. Materials and Methods: As a single-center observational study, children aged 0–23 months received injectable drugs from April 1, 2018, to March 31, 2023 were included. Information on PHE exposure and adverse events after administration were extracted from medical records. Sodium benzoate, benzyl alcohol, ethanol, glycerol, lactose, polyethylene glycol paraben, polysorbate, propylene glycol, sorbitol, sucrose, sulfite, and thimerosal were selected as PHEs. Results and Discussion: 6265 cases, 333,694 prescriptions, and 368 drugs (264 ingredients) were analyzed. The median age was 0.63 years (interquartile range [IQR] 0.1–1.1). 72,133 prescriptions, 132 drugs and 99 ingredients contained PHE; 2,961 cases exposed to PHE and 1825 cases exceeding permitted daily exposure. The drug with the highest number of exposure cases was hydroxyzine, and the highest number of prescriptions was heparin (both drugs contain benzyl alcohol). In association between adverse events and PHE exposure, higher doses in cases of adverse event occurrence were found in benzyl alcohol, glycerol, polyethylene glycol, and polysorbate exposed cases. Among thimerosal-exposed cases, "developmental delay" was more frequent in exposed cases, but the causal relationship was unknown. Further investigation is needed to clarify the relationship between adverse events and PHE exposure. Additionally, more precise information on PDE for pediatrics including neonates is necessary.

Sulfamethoxazole trimethoprim (ST) combinations are used to prevent infection in immunocompromised patients. In pediatric patients, conventional ST combination tablets (cTab) are large and granules are not preferred due to their rough and bitter taste in the mouth. Since a new formulation of smaller tablets (sTab, 1 cTab = 1-gram granules = 4 sTab) was approved, a study regarding the usability of sTab in pediatric patients was conducted. Children who started taking sTab of the ST combination at our hospital between August 2021 and August 2022 were included. Using an anonymous questionnaire, the dosage of ST combinations, the child's response (3-point visual scale: positive, neutral, or negative), preparation and administration time, and method of taking the drug were asked. Twenty-two patients (median age: 11.0 years) receiving cTab. Median (range) number of tablets per dose was 1 (0.5–1.5) tablet, and was 4 tablets (1.0–4.0) after switching to sTab. Twenty patients (median age: 5.0 years) receiving granules. Median (range) single dose was 0.75 (0.2–2.0) gram, and was 2.0 (1.0–4.0) tablets after switching to sTab. Post-dose reactions were positive in 5, neutral in 7, and negative in 10 cases for cTab, and positive in 1, neutral in 7, and negative in 12 cases for granules. After switching to sTab, 9, 13 and 0 cases, and 10, 9 and 1 cases were positive, neutral, and negative, respectively. Median preparation and administration times were decreased after switching to sTab in both cTab and granules groups. The frequency of dosage manipulations was also decreased. The switch to sTab improved acceptability, and decreased burden of administration, suggesting that sTab is a user-friendly formulation in pediatric medications. [ABSTRACT FROM AUTHOR]

Background: Powders for oral solutions and suspensions (POS) are commonly used as pediatric oral medicines worldwide, except for Japan. Although global pediatric formulation development accelerates POS importation to Japan without any formulation change, oral solid multiparticulates remain to be the preferred pediatric forms in the country. This study aimed to evaluate the acceptance situation of four typical POS form products (mycophenolate mofetil, sildenafil citrate, valganciclovir hydrochloride, and voriconazole) that were recently approved in Japan. Methods: A questionnaire on four products was completed by pharmacists in 29 children's hospitals with more than 100 beds each, between November and December of 2019. The questionnaire has six items on (#1) type of institution, (#2) formulary status, (#3) dispensing practice, (#4) reasons why POS form(s) were not selected as hospital formulary, (#5) advantages and disadvantages of POS form, and (#6) opinions for POS form. Results: Of the 29 institutions, 7 (24%), 9 (31%), 4 (13%), and 10 (34%) institutions used POS of mycophenolate mofetil, sildenafil citrate, valganciclovir hydrochloride, and voriconazole, respectively. Reasons for not using these products were dispensed drug loss, formulation issues, and management issues in the pharmaceutical department and pediatric ward. Pharmacists preferred drug compounding such as tablet crushing and capsule opening to POS form use. Conclusions: POS forms might be an unsuitable formulation for the current hospital settings in Japan. Thus, appropriate dosage forms that reflect the current clinical settings are necessary.

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. [ABSTRACT FROM AUTHOR]

Administration devices are crucial for the correct dosing of medicines to children. In countries outside Japan, oral droppers and syringes are reported to be preferred for the administration of oral liquid medicines to neonates and infants, whilst spoons and cups are more frequently used for older children. However, in Japan the majority of oral medicines are powders and the use of dosing devices in each pediatric age group is not well known. This study was performed as an observational anonymous questionnaire survey on devices for oral medicines in children aged 10 to less than 18 years and parents/caregivers on behalf of children aged from birth to less than 18 years. The results from 336 respondents showed that powders were most frequently prescribed in children aged less than 10 years old followed by liquids. Unlike previous reports, droppers were most frequently used in patients less than 12 months old, while household spoons were most frequently used in older children. Oral syringes were perceived as easy to use, which was in line with previous studies. Further cross-regional multi-countries study for establishment the guidelines on the choice of device will be needed. [ABSTRACT FROM AUTHOR]

Antibiotics are among the most commonly prescribed drugs in children. Adherence to the treatment with these drugs is of the utmost importance to prevent the emergence of resistant bacteria, a global health threat. In children, medicine acceptability is likely to have a significant impact on compliance. Herein we used a multivariate approach, considering simultaneously the many aspects of acceptability to explore the drivers of oral antibiotic acceptability in children under twelve, especially in toddlers and in preschoolers. Based on 628 real-life observer reports of the intake of 133 distinct medicines, the acceptability reference framework highlighted the influence of many factors such as age and sex of patients, previous exposure to treatment, place of administration, administration device, flavor agent in excipients and active pharmaceutical ingredient. These findings from an international observational study emphasize the multidimensional nature of acceptability. Therefore, it is crucial to consider all these different aspects for assessing this multi-faceted concept and designing or prescribing a medicine in order to reach adequate acceptability in the target population.
