Demonstrating Evidence of Acceptability: The “Catch-22” of Pediatric Formulation Development
European Paediatric Formulation Initiative workshop report: Improving the administration of oral liquid medicines in paediatrics using dosing syringes and enteral accessories
Accurate dosing of the right medicine to the right patient is a key element of safe and efficacious pharmacotherapy, yet prone to technical challenges and human error when dosing involves the administration of small volumes of liquid medicines. For this reason, the topic has gained increased attention over the last decade from multiple stakeholder parties e.g. academia, hospital pharmacy, the medical device and pharmaceutical industry, and regulatory agencies. It is now well acknowledged that spoons and cups are not suitable for the measurement of small volumes of oral liquid medicines and that syringes are a better alternative, but syringes for parenteral use should not be used for oral dosing in order to avoid accidental parenteral delivery of oral products. However, dosing accuracy of very small volumes of liquid medicines to young children, and especially pre-term neonates, is still not sufficiently ensured. A workshop was organised in 2018 by the European Paediatric Formulation Initiative to reflect on current status and challenges (first part) and possible strategies to improve the present situation (second part). A voting system (n = 24) was used to consider the most favourable solutions. The harmonisation and/or standardisation of the technical design of oral syringes (including e.g. female/male connection) was considered a key priority
Age-Related Medicine
A meeting organised by the Academy of Pharmaceutical Sciences focussed on the challenges of developing medicines for older adults. International experts discussed the complexity introduced by polypharmacy and multiple morbidities and how the risk–benefit ratio of a medicine changes as an individual ages. The way in which regulatory authorities are encouraging the development of age-appropriate medicines was highlighted. Examples were provided of the difficulties faced by the older population with some medicinal products and suggestions given as to how the pharmaceutical scientist can build the requirements of the older population into their development of new medicines, as well as improvements to existing ones
Opportunities for changes in the drug product design to enhance medication safety in older people:Evaluation of a national public portal for medication incidents
AIMS: Medication safety requires urgent attention in hospital pharmacy. This study evaluated the medication‐related problems/errors as reported to the Dutch medication incident registry and disseminated for information to pharmacists. Through analysis by an expert panel we aimed to better understand which problems could have been mitigated by the drug product design. Additionally, the (wider) implications of the problems for current hospital/clinical practice were discussed. METHODS: Items were extracted from the public Portal for Patient Safety. Items were included if relevant for older people and connected with the drug product design and excluded if they should reasonably have been intercepted by compliance to routine controls or well‐known professional standards in pharmaceutical care. To explore any underreporting of well‐known incidents, it was investigated if different medication‐related problems could be observed in a regional hospital practise over a 1‐month period. For 6 included items (cases), the implications for hospital/clinical practise were discussed in an expert panel. RESULTS: In total, 307 items were identified in the Portal for Patient Safety; all but 14 were excluded. Six cases were added from daily hospital practice. These 20 cases commonly related to confusing product characteristics, packaging issues such as the lack of a single unit package for an oncolytic product, or incorrect or incomplete user instructions. CONCLUSION: Medication registries provide important opportunities to evaluate real‐world medication‐related problems. However, underreporting of well‐known problems should be considered. The product design can be used as an (additional) risk mitigation measure to support medication safety in hospital practice

Microparticle surface layering through dry coating: impact of moisture content and process parameters on the properties of orally disintegrating tablets
Objectives: The aim of this study was to investigate the influence of process parameters during dry coating on particle and dosage form properties upon varying the surface adsorbed moisture of microcrystalline cellulose (MCC), a model filler/binder for orally disintegrating tablets (ODTs).
Methods: The moisture content of MCC was optimised using the spray water method and analysed using thermogravimetric analysis. Microproperty/macro-property assessment was investigated using atomic force microscopy, nano-indentation, scanning electron microscopy, tablet hardness and disintegration testing.
Key findings: The results showed that MCC demonstrated its best flowability at a moisture content of 11.2% w/w when compared to control, comprising of3.9% w/w moisture. The use of the composite powder coating process (without air) resulted in up to 80% increase in tablet hardness, when compared to the control. The study also demonstrated that surface adsorbed moisture can be displaced upon addition of excipients during dry processing circumventing the need for particle drying before tabletting.
Conclusions: It was concluded that MCC with a moisture content of 11% w/w provides a good balance between powder flowability and favourable ODT characteristics
Oral medicine acceptance in infants and toddlers: measurement properties of the caregiver-administered Children’s acceptance tool (CareCAT)
BACKGROUND: Developing age-appropriate medications remains a challenge in particular for the population of
infants and toddlers, as they are not able to reliably self-report if they would accept and consequently take an oral
medicine. Therefore, it is common to use caregivers as proxies when assessing medicine acceptance. The outcome
measures used in this research field differ and most importantly lack validation, implying a persisting gap in
knowledge and controversy in the field. The newly developed Caregiver-administered Children’s Acceptance Tool
(CareCAT) is based on a 5-point nominal scale, with descriptors of medication acceptance behavior. This crosssectional
study assessed the measurement properties of the tool with regards to the user’s understanding and its
intra- and inter-rater reliability.
METHODS: Participating caregivers were enrolled at a primary healthcare facility where their children (median age
6 months) had been prescribed oral antibiotics. Caregivers, trained observers and the tool developer observed and
scored on the CareCAT tool what behavior children exhibited when receiving the medicine (n = 104). The videorecords
of this process served as replicate observations (n = 69). After using the tool caregivers were asked to
explain their observations and the tool descriptors in their own words. The tool’s reliability was assessed by
percentage agreement and Cohen’s unweighted kappa coefficients of agreement for nominal scales.
RESULTS: The study found that caregivers using CareCAT had a satisfactory understanding of the tool’s descriptors.
Using its dichotomized scores the tool reliably was strong for acceptance behavior (agreement inter-rater 84–88%,
kappa 0.66–0.76; intra-rater 87–89%, kappa 0.68–0.72) and completeness of medicine ingestion (agreement inter-rater
82–86%, kappa 0.59–0.67; intra-rater 85–93%, kappa 0.50–0.70).
CONCLUSIONS: The CareCAT is a low-cost, easy-to-use and reliable instrument, which is relevant to assess acceptance
behavior and completeness of medicine ingestion, both of which are of significant importance for developing
age-appropriate medications in infants and toddlers
Association between culture and the preference for, and perceptions of, 11 routes of medicine administration: A survey in 21 countries and regions
Medicines can be taken by various routes of administration. These can impact the effects and perceptions of medicines. The literature about individuals' preferences for and perceptions of the different routes of administration is sparse, but indicates a potential influence of culture. Our aim was to determine: (i) any association between one's culture and one's preferred route of medicine administration and (ii) individual perceptions of pain, efficacy, speed of action and acceptability when medicines are swallowed or placed in the mouth, under the tongue, in the nose, eye, ear, lungs, rectum, vagina, on the skin, or areinjected. A cross-sectional, questionnaire-based survey of adults was conducted in 21 countries and regions of the world, namely, Tunisia, Ghana, Nigeria, Turkey, Ethiopia, Lebanon, Malta, Brazil, Great Britain, United States, India, Serbia, Romania, Portugal, France, Netherlands, Japan, South Korea, Hong Kong, mainland China and Estonia, using the Inglehart–Welzel cultural map to ensure coverage across all cultures. Participants scored the pain/discomfort, efficacy, speed of onset and acceptability of the different routes of medicine administration and stated their preferred route. Demographic information was collected. A total of 4435 participants took part in the survey. Overall, the oral route was the most preferred route, followed by injection, while the rectal route was the least preferred. While the oral route was the most preferred in all cultures, the percentage of participants selecting this route varied, from 98% in Protestant Europe to 50% in the African-Islamic culture. A multinomial logistic regression model revealed a number of predictors for the preferred route. Injections were favoured in the Baltic, South Asia, Latin America and African-Islamic cultures while dermal administration was favoured in Catholic Europe, Baltic and Latin America cultures. A marked association was found between culture and the preference for, and perceptions of the different routes by which medicines are taken. This applied to even the least favoured routes (vaginal and rectal). Only women were asked about the vaginal route, and our data shows that the vaginal route was slightly more popular than the rectal one
Personalised dosing: Printing a dose of one's own medicine
© 2015 Elsevier B.V. All rights reserved. Ink-jet printing is a versatile, precise and relatively inexpensive method of depositing small volumes of solutions with remarkable accuracy and repeatability. Although developed primarily as a technology for image reproduction, its areas of application have expanded significantly in recent years. It is particularly suited to the manufacture of low dose medicines or to short production runs and so offers a potential manufacturing solution for the paradigm of personalised medicines. This review discusses the technical and clinical aspects of ink-jet printing that must be considered in order for the technology to become widely adopted in the pharmaceutical arena and considers applications in the literature
