Commentary on the EMA reflection paper on the pharmaceutical development of medicines for use in the older population.

Older people are often affected by impaired organ and bodily functions resulting in multimorbidity and polypharmacy, turning them into the main user group of many medicines. Very often, medicines have not specifically been developed for older people, causing practical medication problems for them like limited availability of easy to swallow formulations, easy to open packaging and dosing instructions for enteral administration. In 2020, the European Medicines Agency (EMA) published a reflection paper 'Pharmaceutical development of medicines for use in the older population', which discusses how the emerging needs of an ageing European population can be addressed by medicines regulation.

Developing patient-centric medicines for older people: Reflections from the draft EMA paper on the pharmaceutical development of medicines for use in the older population.

Increased global longevity requires a re-evaluation of current structures in society to adapt to the consequential demographic shift. As (very) old people are prone to impaired human organ and body functions resulting in, for example, multimorbidity, polypharmacy, hospitalisation and problems in medication management, it is increasingly acknowledged that re-evaluations should include the suitability of pharmaceutical patient care as one of the cornerstones of public health. Following the 2011 European Medicines Agency (EMA) Geriatric Strategy, in 2017 the EMA published the draft "Reflection paper on the pharmaceutical development of medicines for use in the older population".

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.

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.

The development of a test battery to assess the hand-eye functions relevant in predicting easy and accurate tablet subdivision in older people: A pilot study.

Aims: Tablets may be subdivided for dose adaptations or to ease swallowing. The handling is common in older patients but can be difficult and inaccurate. Currently, it is not known which hand-eye functions determine the ability of older people to break tablets by hand and to do so with acceptable ease and accuracy.

Achieving appropriate medication for older adults: A multidimensional perspective.

Achieving appropriate medication is a multidimensional process. Current research on polypharmacy mainly focuses on drug appropriateness, but little is devoted to what determines the ongoing challenge. The authors, with their diverse clinical, pharmaceutical and regulatory backgrounds, offer a narrative review on the causes of inappropriate polypharmacy and how to avoid it.

The mechanisms of pharmacokinetic food-drug interactions - A perspective from the UNGAP group.

The simultaneous intake of food and drugs can have a strong impact on drug release, absorption, distribution, metabolism and/or elimination and consequently, on the efficacy and safety of pharmacotherapy. As such, food-drug interactions are one of the main challenges in oral drug administration. Whereas pharmacokinetic (PK) food-drug interactions can have a variety of causes, pharmacodynamic (PD) food-drug interactions occur due to specific pharmacological interactions between a drug and particular drinks or food.

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.

[Oral drops: unsafe or unwieldy method of administration?].

The Netherlands Medicines Evaluation Board (MEB) was recently informed about a serious pipamperone overdose in a 6-year-old boy, which happened because the boy was given the medication in streams rather than in drops. This article describes the use of drops in pharmaceutical patient care and explains why the MEB has maintained marketing authorization for the product on the basis of currently available information. The MEB urgently requests the healthcare professional groups to report all problems concerning drug use to the Netherlands Pharmacovigilance Centre Lareb, and the Portal for Patient Safety; this is the only way in which it can be verified whether incidental medication errors are actually, and continue to be, incidental.

Actual versus recommended storage temperatures of oral anticancer medicines at patients' homes.

Background: Substantial quantities of unused medicines are returned by patients to the pharmacy each year. Redispensing these medicines would reduce medicinal waste and health care costs. However, it is not known if medicines are stored by patients as recommended in the product label.

Patients' appropriateness, acceptability, usability and preferences for pharmaceutical preparations: Results from a literature review on clinical evidence.

Patients play an important role in achieving the desired therapeutic outcomes, as they are frequently responsible for their own medication management. To facilitate drug administration and overcome medication issues, the patients' needs and preferences should be considered in the pharmaceutical drug product design. With the aim to evaluate the current state of evidence for patient appropriateness, acceptability, usability and preference for aspects of this design, a literature search was performed.

Defining Patient Centric Pharmaceutical Drug Product Design.

The term "patient centered," "patient centric," or "patient centricity" is increasingly used in the scientific literature in a wide variety of contexts. Generally, patient centric medicines are recognized as an essential contributor to healthy aging and the overall patient's quality of life and life expectancy. Besides the selection of the appropriate type of drug substance and strength for a particular indication in a particular patient, due attention must be paid that the pharmaceutical drug product design is also adequately addressing the particular patient's needs, i.

Paediatric Drug Development and Formulation Design-a European Perspective.

The availability of licensed paediatric drugs is lagging behind those for adults, and there is a lack of safe formulations in suitable doses that children are able and willing to take. As a consequence, children are commonly treated with off-label or unlicensed drugs. As off-label and unlicensed drug use are associated with a greater risk for harm than on-label drug use, a range of global initiatives have been developed to realize "better" medicines for children.

Regulatory incentives to ensure better medicines for older people: From ICH E7 to the EMA reflection paper on quality aspects.

Ageing comes with an increased propensity in the alteration of human organ and body functions, which can e.g. result in multi-morbidity, frailty, polypharmacy, altered medication safety and/or efficacy, and problems with the practical use of medicines in a real world setting.

Safe and effective pharmacotherapy in infants and preschool children: importance of formulation aspects.

Safe and effective paediatric pharmacotherapy requires careful evaluation of the type of drug substance, the necessary dose and the age-appropriateness of the formulation. Generally, the younger the child, the more the attention that is required. For decades, there has been a general lack of (authorised) formulations that children are able to and willing to take.

Methods of administering oral formulations and child acceptability.

Introduction: Children may be unable or unwilling to swallow medicines. In order to avoid or accommodate any such problems, parents may decide to administer medicines other than intended. The aim of this study was to investigate how parents administered four oral placebo formulations to infants and preschool children and how the applied methods correlated with child acceptability.

Practical problems with medication use that older people experience: a qualitative study.

Objectives: To identify the practical problems that older people experience with the daily use of their medicines and their management strategies to address these problems and to determine the potential clinical relevance thereof.

Design: Qualitative study with semistructured face-to-face interviews.

Setting: A community pharmacy and a geriatric outpatient ward.

Authors' response to the letter from Kalleian Eserian et al.

This letter is a response to the comments of Kalleian Eserian et al. on our study relating to the accuracy, precision and sustainability of six tablet splitters and a kitchen knife as an alternative to breaking paracetamol 500mg tablets by hand. We would like to inform the readers of International Journal of Pharmaceutics that our study focused on splitting tablets with a mechanical tool rather than breaking tablets by hand.

Results from a preliminary review of scientific evidence for appropriateness of preparations, dosage forms and other product design elements for older adult patients.

The aging population and the growing multimorbidity of the major patient population as well as the advanced (pharmaco)therapeutic treatment options are increasing the complexity of independent drug therapy management and administration. The increased complexity may have an impact on drug adherence (including any need for patients initiated coping strategies), and consequently on the safety and efficacy of the medicine. To overcome adherence issues caused by the design of the medicine, it is crucial that developers consider the age appropriateness of the medicine (route of administration, dosage form, excipients in the composition, frequency of dosing) in meeting patients' needs to manage their therapy without the support of a care giver.

Oral medicines for children in the European paediatric investigation plans.

Introduction: Pharmaceutical industry is no longer allowed to develop new medicines for use in adults only, as the 2007 Paediatric Regulation requires children to be considered also. The plans for such paediatric development called Paediatric Investigation Plans (PIPs) are subject to agreement by the European Medicines Agency (EMA) and its Paediatric Committee (PDCO). The aim of this study was to evaluate the key characteristics of oral paediatric medicines in the PIPs and the changes implemented as a result of the EMA/PDCO review.

The accuracy, precision and sustainability of different techniques for tablet subdivision: breaking by hand and the use of tablet splitters or a kitchen knife.

Introduction: Tablets are frequently subdivided to lower the dose, to facilitate swallowing by e.g. children or older people or to save costs.

Acceptability of different oral formulations in infants and preschool children.

Objective: Liquid medicines are easy to swallow. However, they may have disadvantages, such as a bad taste or refrigerated storage conditions. These disadvantages may be avoided by the use of oral solid medicines, such as powders or tablets.
