136106.pdf (publisher's version ) (Open Access)INTRODUCTION: Tablets are frequently subdivided to lower the dose, to facilitate swallowing by e.g. children or older people or to save costs. Splitting devices are commonly used when hand breaking is difficult or painful. METHODS: Three techniques for tablet subdivision were investigated: hand breaking, tablet splitter, kitchen knife. A best case drug (paracetamol), tablet (round, flat, uncoated, 500 mg) and operator (24-year student) were applied. Hundred tablets were subdivided by hand and by three devices of each of the following types: Fit & Healthy, Health Care Logistics, Lifetime, PillAid, PillTool, Pilomat tablet splitter; Blokker kitchen knife. The intra and inter device accuracy, precision and sustainability were investigated. The compliance to (adapted) regulatory requirements was investigated also. RESULTS: The accuracy and precision of hand broken tablets was 104/97% resp. 2.8/3.2% (one part per tablet considered; parts right/left side operator). The right/left accuracies of the splitting devices varied between 60 and 133%; the precisions 4.0 and 29.6%. The devices did not deteriorate over 100-fold use. Only hand broken tablets complied with all regulatory requirements. CONCLUSION: Health care professionals should realize that tablet splitting may result in inaccurate dosing. Authorities should undertake appropriate measures to assure good function of tablet splitters and, where feasible, to reduce the need for their use
Ouderen krijgen tablet of capsule moeilijk uit blister : Meerderheid ervaart een probleem met gebruik van geneesmiddelen
Ouderen ondervinden een groot aantal praktische problemen bij het gebruik van geneesmiddelen. Incorrect gebruik van geneesmiddelen kan klinische gevolgen hebben. Dit blijkt uit onderzoek van het Rijksinstituut voor Volksgezondheid en Milieu in samenwerking met de Universiteit Utrecht
Authors' response to the letter from Kalleian Eserian et al
Item does not contain fulltextThis 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. Although publications on hand breaking tablets were not cited for this reason, we are familiar with the conclusions of these publications. This is especially true for the publications that were written by direct colleagues from the department of the corresponding author e.g., Van Santen et al. and Van der Steen et al
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. The paper intends to help industry to better consider the needs of older people during pharmaceutical/clinical medicines development by summarising data on the most relevant topics, providing early suggestions on how to move forward and prompting expert discussions and studies into knowledge gaps. Topics include patient acceptability, (dis)advantages of an administration route, formulation, dosage form, packaging, dosing device and user instruction. While the paper is directed at older people and the pharmaceutical industry, the reflections are also relevant to younger patients with similar disease-related needs and of value to other stakeholders parties, e.g., healthcare professionals, academics, patients and caregivers, as the paper makes clear what can be expected from industry and where collaborative work is needed. This commentary provides an overview of the different steps in the development of the reflection paper, discusses points considered most controversial and/or subject to (multidisciplinary) expert discussions and indicates their value for real world clinical practice
