Introduction: A medicine's acceptability is likely to have significant impact on pediatric adherence. The importance is underlined in EMA and FDA guidance on this topic where investigation of acceptability is stated as a regulatory expectation. Demonstrating acceptability can be challenging given there is no globally recognized definition and no standardized testing methodology or assessment criteria. Palatability and swallowability are generally recognized as important elements of acceptability, and this work proposes a definition of acceptability using these elements to give a composite endpoint for acceptability for pediatric subjects across all age ranges. Methods: This composite acceptability endpoint is based on validated assessment methods for swallowability and palatability in children of different age groups using different galenic placebo formulations, in line with criteria proposed by EMA for assessing acceptability in children from newborn to 18 years of age. Data from two studies investigating mini-tablets, oblong tablets, orodispersible films, and syrup were analyzed to establish the validity, expediency, and applicability of the suggested composite acceptability assessment tool. Results: The new composite endpoint is an efficient and suitable way to distinguish preferences of oral formulations: Mini-tablets and oblong tablets had significantly better acceptability than syrups and orodispersible films. Conclusion: Since the suggested acceptability criteria takes both swallowability and palatability into account as composite endpoint, it is highly sensitive to detect acceptability differences between oral formulations. It is a well-defined valid approach, which meets regulatory requirements in an appropriate and comprehensive manner and may in future serve as a pragmatic, standardized method to assess and compare acceptability of pediatric formulations with active substances.

Palatability and swallowability in the pediatric population are perceived as true challenges in the oral administration of medication. Pediatric patients have high sensitivity to taste and reduced ability to take solid dosage forms, which can often lead to a poor therapeutic compliance. It is crucial to find new strategies to simplify the oral administration of drugs to children. The present paper reports the development of a new hydrogel vehicle adapted to the pediatric population. Several polymers with similar properties were selected and adjustments were made to obtain the desired characteristics of the final product. The developed formulations were studied for organoleptic properties, rheology, mucoadhesion properties, preservative efficacy, and stability. Physical and chemical compatibilities between the vehicle and several drugs/medicines, at the time of administration, were also studied. Six final formulations with different polymers, odor, and color were chosen, and no known interactions with medications were observed. The proposed new oral vehicles are the first sugar-free vehicle hydrogels designed to make the intake of oral solid forms a more pleasant and safer experience for pediatric patients.

To ensure optimal, reliable treatment, it is necessary to investigate the efficacy, safety and the optimal dose of drug substances and to develop suitable age-specific pharmaceutical formulations for the different paediatric age groups due to a lack of evidence-based therapeutic options for children. While WHO recommends the use of solid dosage forms in general, European Medicines Agency (EMA) requires evidence for the suitability of these dosage forms in the targeted age group. This review aims to summarize and discuss the data obtained in acceptability studies on the suitability of coated and uncoated mini-tablets in children of different ages in comparison to a sweet syrup considered as gold standard. The predefined outcome parameters 'acceptability' and 'capability to swallow' of the two different mini-tablet formulations (uncoated and film-coated) were statistically significantly higher than that of the syrup.

The article discusses the industry-based survey performed by the Global Alliance for Pediatric Therapeutics in February 2013 to assess current industry practices evaluating the palatability and swallowability of pediatric oral solid dosage forms. The survey looked into areas where regulatory guidance is necessary. Six research-based pharmaceutical companies and American Academy of Pediatrics members participated in the survey.

The article investigates the tools used to evaluate the palatability and swallowability of pediatric oral dosage forms and determines a correlation between palatability and treatment adherence. Papers in the English language published from January 2008 to March 2013 were referenced for the study, with 137 citations and 27 articles utilized for assay. Limited evidence was found on the two's association.

Aim:The aim of the study was to investigate the swallow ability and the patient preferences of tablets and capsules with different sizes, shapes, surfaces and colours. Method: Patients were asked to swallow tablets with different surface and size, while tablets with different shape and colour were visually assessed. They were asked to indicate their preferences. Results: Gelatine capsules were found easier to swallow than tablets and coated tablets were found easier than uncoated normal tablets. The preferred colour was white both for tables and capsules, and the most disliked colours were purple tablets and brown capsules. The preferred shape was strongly arched circular for small tablets, oval for medium sized and big tablets. The difficulty to swallow tablets increased with increasing size. Conclusion: According to the results of this study, the ideal tablet is small and white, strongly arched circular and coated. If the amount of drug requires a bigger tablet, the preferred fomat is oblong or oval with a coating. In general capsules were preferred over tablets. [ABSTRACT FROM AUTHOR]

Purpose: Medicine acceptability, which is of the utmost importance for vulnerable patients’ adherence, is driven by both user and product characteristics. Herein, a novel multivariate approach integrating the many aspects of acceptability is used to discriminate positively and negatively accepted medicines in the older population.Methods: An observational study was carried out in eight hospitals and eight nursing homes to collect a large set of real-life data on medicines uses in older patients (≥65 years). Mapping and clustering explored these multiple observational measures and summarised the main information into an intelligible reference framework. Resampling statistics were used to validate the model’s reliability.Results: A three-dimensional map and two clusters defining acceptability profiles, as positive or negative, emerged from the 1079 evaluations. Factors of interest (medicines, user features…) were positioned on the map at the barycentre of their evaluations and assigned to an acceptability profile. Focusing on patients’ ability to swallow, we have highlighted the tool’s efficacy in demonstrating the impact of user features on medicine acceptability.Conclusions: This multivariate approach provides a relevant judgement criterion for this multi-dimensional concept. Facilitating the choice of the most appropriate dosage form to achieve optimal acceptability in a targeted population, this tool is of real potential to improve clinical decisions.
