Questionnaire Study to Investigate the Preferences of Children, Parents, and Healthcare Professionals for Different Formulations of Oral Medicinal Products.

Since the acceptability of a medicine can significantly impact therapeutic outcomes, this study aimed to determine and compare the preferences of children, parents, and healthcare professionals for the most commonly used pediatric oral medicine formulations (syrup, mini-tablets, oblong tablets, round tablets) addressing all pediatric age groups, 0-<18 years (y). This survey study employed sex-, age-, and participant group-adapted questionnaires for eight cohorts of participants, i.e., children 6-<12 y, adolescents 12-<18 y, parents of children in four age groups (0-<2 y, 2-<6 y, 6-<12 y, and 12-<18 y), nurses, and pediatricians. Descriptive statistics were used for data analysis. In the age groups 0-<2 y and 2-<6 y, mini-tablets were preferred over syrup by all participants. In the age group 6-12 y, solid dosage forms were also preferred over syrup by all participants. In the age group 12-<18 y, healthcare professionals preferred solid dosage forms over syrup. Parents preferred higher amounts of mini-tablets and syrup compared to round and oblong tablets, while adolescents' preferences did not differentiate between these formulations. Based on the study results and in contrast to current practice, it is suggested to consider solid dosage forms for future age-appropriate medicinal products already for younger age groups.

Dosage Forms Suitability in Pediatrics: Acceptability of Antibiotics in a German Hospital.

Although drug acceptability can have a significant impact on patient adherence in pediatric therapy, data are limited, even for common therapeutic areas. We present the second part of an acceptability study conducted at the University Children's Hospital Düsseldorf, Germany. The study investigated the acceptability of most commonly used antibiotics in a pediatric hospital setting. The researchers used the acceptability reference framework to score the acceptability of five antibiotics based on 150 real-life observer reports of medicine intake. Four antibiotics assessed in this study were formulated as preparations for injection (ampicillin, ampicillin/sulbactam, ceftriaxone, and gentamicin) and one as a powder for oral liquid suspension (co-amoxiclav). All the antibiotics formulated as preparations for injection were rated negatively due to high rates of negative reactions (80%), the use of restraint (51%), the use of extra devices (99%), and long preparation and administration times (100%). The antibiotic formulated as a powder was significantly more well accepted. The study concluded that there is a lack of appropriate formulations for antibiotics for use in children. These findings are important in improving knowledge on acceptability drivers and might help in formulating and prescribing better medicines for children. The study highlights the need for healthcare professionals to have knowledge about the acceptability of different products to select the best-adapted product for each patient.

Young patients' involvement in a composite endpoint method development on acceptability for paediatric oral dosage forms.

BACKGROUND: In line with the European Paediatric Regulation, the European Medicines Agency (EMA) asks for investigation of a medicine's acceptability in paediatric medicines development. A standardised acceptability testing method combining the outcome of "swallowability" and "palatability" assessments to a "composite endpoint on acceptability" was recently developed. Before this method's suitability for selection of the most acceptable drug formulation of a new medicine for children can be broadly recommended, the acceptance and relevance of such established acceptability needs the critical review and input from young patients with understanding of the medicines development methodology. The benefit of involving patients in drug product development, clinical research and innovation is well established. METHODS: During a focus group meeting with the KIDS Barcelona (young people advisory group, age 16-23 years) the suitability of the "composite endpoint on acceptability" methodology was assessed. Via electronic questionnaires the importance of involving patients in the medicines development and in the acceptability method development was investigated. Questions on how best to determine palatability and swallowability were asked. The relevance of all EMA-listed acceptability elements was assessed via coloured and numbered stickers and questionnaires. RESULTS: The results showed that the involvement of young people in the medicines and acceptability method development was rated high. The group worked out that a 5-point smiley Likert Scale is preferred for assessing acceptability by 6-11 year old patients, while a Visual Analogue Scale is preferred for collecting adolescents' opinion. The ranking of the EMA-listed acceptability elements showed that palatability and swallowability are the most relevant parameters, while colour of the medicine was rated as least relevant. These results, established face-to-face, were confirmed in a repeat of the ranking through an electronic questionnaire, completed by the participants individually and remotely, 5 weeks later. CONCLUSION: This work reinforced the need and value to involve young people in the medicines lifecycle, and specifically in this acceptability method development. As next step other focus group meetings with more young people from different European countries are planned.

Before a new medicine is authorized, its acceptability by children must be investigated according to law. An acceptability testing method combining the outcomes of "swallowability" and "palatability" assessments was recently developed. During a focus group meeting with KIDS Barcelona (young people advisory group, age 16­23 years) their opinion on the suitability of the method and the relevance of patient engagement in the medicines development process were assessed with paper-based and electronic questionnaires. Questions on how best to determine palatability and swallowability were asked. The importance of different elements that typically affect acceptability was rated. The order of relevance of those listed acceptability elements was assessed using coloured and numbered stickers and questionnaires. The results showed that the involvement of young people in the medicines and acceptability method development was rated high. The group worked out that a 5-point smiley Likert Scale that allows for marking a choice between total agreement and total disagreement is preferred for assessing acceptability by 6­11 year old patients. A Visual Analogue Scale (scale consisting of a 10 cm long line on which a mark has to be placed at the desired position, between total agreement and total rejection) is preferred for collecting adolescents' (12­18 years) opinion. The ranking of acceptability elements showed that palatability and swallowability of a new medicine are the most relevant parameters, and colour the least. The clarity of the outcome reinforced the benefit of involving young people in the development of medicines relevant for children.

Evaluating the Acceptability, Swallowability, and Palatability of Film-Coated Mini-Tablet Formulation in Young Children: Results from an Open-Label, Single-Dose, Cross-Over Study.

Mini-tablets are advantageous over liquid formulations in overcoming challenges related to stability, taste, and dosage. This open-label, single-dose, cross-over study investigated the acceptability and safety of drug-free, film-coated mini-tablets in children aged 1 month-6 years (stratified: 4-6 years, 2-<4 years, 1-<2 years, 6-<12 months, and 1-<6 months), and their preference for swallowing either a high quantity of 2.0 mm or a low quantity of 2.5 mm diameter mini-tablets. The primary endpoint was acceptability derived from swallowability. The secondary endpoints were investigator-observed palatability, acceptability as a composite endpoint derived from both swallowability and palatability, and safety. Of 320 children randomized, 319 completed the study. Across all tablet sizes, quantities and age groups, acceptability rates based on swallowability were high (at least 87%). Palatability was rated as "pleasant/neutral" in 96.6% of children. The acceptability rates as per the composite endpoint were at least 77% and 86% for the 2.0 mm and 2.5 mm film-coated mini-tablets, respectively. No adverse events or deaths were reported. Recruitment in the 1-<6-months group was stopped early due to coughing-evaluated as "choked on" in three children. Both 2.0 mm and 2.5 mm film-coated mini-tablets are suitable formulations for young children.

Patient-centric drug product development: Acceptability across patient populations - Science and evidence.

The 6th APV (Arbeitsgemeinschaft für Pharmazeutische Verfahrenstechnologie e.V., The International Association for Pharmaceutical Technology) Winter Conference took place in Salzburg (Austria) from January 19-20, 2023. This conference was dedicated to advance patient-centric drug development across all dosage forms, indications and patient populations and was organized by the APV PaCeMe IN Task Force. The topic was chosen due to emerging evidence and increasing regulatory requirements to consider patient needs and capabilities in drug product development. It is well acknowledged that acceptability of a drug product and its dosage form is a fundamental aspect of patient centric drug product design which can directly impact adherence and intended use, hence effectiveness and safety. Despite the requirement to proof acceptability within the drug development program, respective methods to determine and compare the degree of acceptability of different dosage forms and drug product designs are still limited.

Acceptability of multiple coated mini-tablets in comparison to syrup in infants and toddlers: a randomised controlled study.

OBJECTIVES: Drug treatment of children is often limited to liquid formulations or manipulation of adult solid oral dosage forms because of the lack of age-appropriate formulations, concerns around particle aspiration and paediatric acceptability. Recent research revealed that the administration of mini-tablets has substantial advantages in improving dose accuracy and avoiding issues related to drug stability, storage conditions, potentially toxic excipients and taste masking (especially effective when the mini-tablets are coated). Most trials were performed with single and multiple uncoated mini-tablets. This study here aimed to investigate young children's acceptability and swallowability of multiple coated placebo mini-tablets compared with glucose syrup. DESIGN: This clinical trial was conducted as a single-centre randomised cross-over study. SETTING: Prospective cross-over study performed at the Children's University Hospital Düsseldorf. PATIENTS: This study was conducted on 50 children in five age groups from 1 to <6 years. INTERVENTIONS: An age-adapted amount of 16-28 mini-tablets and 3-6 mL syrup was administered in randomised order. MAIN OUTCOME MEASURES: Acceptability and swallowability of multiple coated mini-tablets and syrup. RESULTS: In all age groups, administration of multiple coated mini-tablets and syrup showed good acceptability (mini-tablets 80%-100%, syrup 90%-100%) and swallowability (mini-tablets 30%-70%, syrup 20%-80%) without any clinically meaningful difference. This is consistent with results from large studies with uncoated mini-tablets. CONCLUSION: Multiple coated mini-tablets are a suitable age-appropriate alternative to liquid formulations in the paediatric population. No safety concerns with the use of coated mini-tablets were observed in the study. TRIAL REGISTRATION NUMBER: DRKS00010395.

Acceptability, Swallowability, Palatability, and Safety of Multiple Film-Coated Mini-Tablets in Children Aged ≥2-<7 Years: Results of an Open-Label Randomised Study.

This single-centre, open-label, randomised, parallel-group study assessed the acceptability, swallowability, palatability, and safety of film-coated, 3 mm diameter mini-tablets in children aged ≥2-<7 years. In total, 300 participants were randomised (2:2:1:1) to receive a single oral administration of 16 (group A) or 32 (group B) mini-tablets with soft food or 16 (group C) or 32 (group D) mini-tablets with water. Children in each group were stratified by age group (2-<3 years; 3-<4 years; 4-<5 years; 5-<6 years; and 6-<7 years). Groups C and D were pooled for statistical analyses. The rates of acceptability (swallowed ≥80% of the mini-tablets with or without chewing), swallowability (swallowed all mini-tablets without chewing or any leftover), and palatability (positive/neutral responses) were ≥80.0%, ≥42.0%, and ≥82.0%, respectively, across the study groups. No marked differences were observed between groups or across age groups. No adverse events or issues of clinical relevance with deglutition were reported. Mini-tablets taken with soft food or water provide a suitable method for administering medicines to children aged ≥2-<7 years. This study was registered in the German Clinical Trial Register (No. DRKS00024617).

A Composite Endpoint for Acceptability Evaluation of Oral Drug Formulations in the Pediatric Population.

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.

Dosage Forms Suitability in Pediatrics: Acceptability of Analgesics and Antipyretics in a German Hospital.

Although medicine acceptability is likely to have a significant impact on the patient's adherence in pediatrics and therefore on therapy success, there is still little data even for common therapeutic areas. For analgesics/antipyretics, healthcare professionals face a wide variety of products and need knowledge to select the best adapted product for each patient. We investigated acceptability of those products most used at the University Children's Hospital Düsseldorf, Germany. Based on 180 real-life observer reports of medicine intake, we used the acceptability reference framework to score acceptability of six distinct medicines. Both ibuprofen and paracetamol tablets, mainly used in adolescents, were positively accepted. This was not the case for the solution for injection of metamizole sodium. Regarding syrups, mainly used in children under 6 years of age, ibuprofen flavored with strawberry and provided with an oral syringe was positively accepted, while paracetamol flavored with orange and provided with a measuring cup was not. Suppository appeared to be an alternative to oral liquids in infants and toddlers with palatability and administration issues. Differences appeared to be driven by dosage forms and formulations. These findings improve knowledge on acceptability drivers and might help formulating and prescribing better medicines for children.

Exploring Acceptability Drivers of Oral Antibiotics in Children: Findings from an International Observational Study.

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.

Acceptability of small-sized oblong tablets in comparison to syrup and mini-tablets in infants and toddlers: A randomized controlled trial.

OBJECTIVE: There is limited evidence for the acceptability of various drug formulations holding the potential to improve medicines administration to children. Suitable formulations need to meet the requirements of pediatric patients. Previous studies have demonstrated the acceptance of mini-tablets. Oblong tablets may carry more active ingredient content per unit than mini-tablets and could be an important alternative when the drug substance requires administration of higher doses. The primary objective was to demonstrate non-inferiority of acceptability of oblong tablets in comparison to 3 ml glucose syrup in children aged 1 to 5 years. Secondary objectives were investigation of acceptability, swallowability and palatability of mini-tablets, oblong tablets and glucose syrup in children between 1 and 5 years. METHODS: An open, randomized, single dose two-way cross-over design in two parallel study arms was applied. 280 children were stratified to one of five age groups and randomized to receiving one oblong tablet (2.5 × 6 mm) in comparison either to 3 ml glucose syrup or to three mini-tablets (2 × 2 mm). Acceptability and swallowability were assessed according to pre-defined evaluation criteria. The application of the formulations was video documented to evaluate the palatability. RESULTS: As primary objective, non-inferiority was observed regarding acceptability of the oblong tablet compared to syrup in all age groups (84.4% vs 80.1%, difference 4,29% points with 95% CI of -3.00%,11.57%). For swallowability, superiority of the oblong tablet compared to syrup could be shown (74.5% vs. 53.2%, difference 21.26% points, 95% CI of 11.29%, 31.23%). Regarding palatability, <10% of children demonstrated unpleasant reaction after intake of the oblong tablet or mini-tablets as graded by both raters, however, in contrast up to 40% of children after intake of syrup. CONCLUSION: Oblong tablets are a promising, safe alternative to liquid drug formulations and administration of multiple mini-tablets in children.

Acceptability of an orodispersible film compared to syrup in neonates and infants: A randomized controlled trial.

OBJECTIVES: Reliable pediatric pharmacotherapy in all age groups requires the availability of age-appropriate drug administration. Orodispersible films (ODF) are a promising pediatric oral dosage form. ODFs would meet relevant targets: one dosage form matching the full range of pediatric patients, a minimum of non-toxic excipients, a stable drug formulation easily to be produced. However, there is a lack of reliable data on ODFs' acceptability, swallowability and palatability, especially in young children. The primary objective was to demonstrate non-inferiority in acceptability of a drug-free ODF in comparison to glucose syrup in children aged below one year. Secondary objectives were swallowability and palatability of the two formulations. STUDY DESIGN: The study was performed in an open, randomized, two-way cross-over design with three age groups: 2-28 days, 29 days-5 months, 6-12 months. 150 children (N = 50 per age group) were randomized to the order of receiving the ODF (2 × 3 cm) and age-adapted amounts of glucose syrup (0.5-3 mL). Deglutition and swallowing were assessed according to predefined evaluation criteria. The application of the formulations was documented by video to evaluate the palatability. RESULTS: The primary objective was confirmed: Non-inferiority of the acceptability of an ODF compared to syrup was demonstrated, even superiority of the ODF was shown (p < 0.0001). The secondary endpoints demonstrated positive results including the superior swallowability of the ODF in comparison to syrup (p < 0.0001). The palatability assessments were in favor of the ODF. CONCLUSION: ODFs are a promising and safe alternative to liquid formulations, even for children of very young ages.

Drug Formulations: Standards and Novel Strategies for Drug Administration in Pediatrics.

Child-appropriate drug formulations are a prerequisite of successful drug therapy in children. Efficacy and safety must be given for the active pharmaceutical ingredient, but safety also for the used excipients, components of primary packaging materials, and devices. We are presently experiencing exciting times for pediatric drug development, stimulated by previous governmental incentives in both the European Union and the United States. The most important advances in pediatric drug formulation development are reviewed and evaluated in this article. Scientific publications and recent industry strategies indicate a clear shift from liquid dosage forms to novel solid dosage forms. Solid formulations are usually composed from excipients generally regarded as safe, whereas many liquid formulations contain excipients such as preservatives, antioxidants, or taste-masking agents that raise concerns. Further, some recent clinical studies on swallowability, acceptability, and preference indicate superiority for small-sized tablets, so-called mini-tablets, over conventional liquids. In general, multiparticulate solid dosage forms could partly replace the liquids and provide more stable and cheaper alternatives to existing drug products or new developments. Dispersible solid drug dosage forms like orodispersible tablets, mini-tablets and films are even better opportunities for efficient and safe use in pediatrics. Novel measuring and administration devices may facilitate the handling and drug administration of these modern drug dosage forms. Combination products (drug-device combinations) can easily be linked with new e-health technologies in near future to further improve pediatric drug therapy.

Acceptability of Multiple Uncoated Minitablets in Infants and Toddlers: A Randomized Controlled Trial.

OBJECTIVES: To assess the acceptability and swallowability of several minitablets when administered as a unit dose compared with an equivalent dose of syrup in children aged 6 months to 5 years. STUDY DESIGN: The acceptability and swallowability of multiple drug-free minitablets in comparison with glucose syrup was assessed in 372 children of 2 age groups (186 in age group 1 [6-23 months of age] and 186 in age group 2 [2-5 years of age]) in a randomized, 3-way, single administration cross-over study. Age group 1 received 25 minitablets, 100 minitablets, and 5 mL syrup. Age group 2 received 100 minitablets, 400 minitablets, and 10 mL syrup. RESULTS: Superiority was demonstrated in age group 1 for acceptability (25 minitablets, P < .017; 100 minitablets, P < .0001) and swallowability (25 minitablets and 100 minitablets, both P < .0001) compared with syrup. In age group 2, noninferiority of acceptability was found only for 400 minitablets (P < .0003), not for 100 minitablets. Subgroup analysis revealed a strong sequential effect. For swallowability, noninferiority could be demonstrated for 100 minitablets (P < .01) but not for 400 minitablets. CONCLUSIONS: Administration of ≥25 minitablets is well-tolerated, feasible, and safe in children aged from 6 months, and was superior to the equivalent dose of syrup. Children aged >1 year accept ≤400 minitablets even better than the equivalent dose of syrup. Minitablets open the perspective for introducing small-sized solid drug formulations for all children, thus, further shifting the paradigm from liquid toward small-sized solid drug formulations.

Acceptability of Mini-Tablets in Young Children: Results from Three Prospective Cross-over Studies.

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.

Acceptability of Uncoated Mini-Tablets in Neonates--A Randomized Controlled Trial.

OBJECTIVE: To evaluate the suitability of drug-free solid dosage forms (2 mm mini-tablets) as an alternative administration modality in neonates in comparison with syrup. STUDY DESIGN: A total of 151 neonates (inpatients; aged 2-28 days; median 4 days) were recruited. An open, randomized, prospective cross-over study was conducted to compare the acceptability and swallowability of 2 mm uncoated mini-tablets compared with .5 mL syrup. RESULTS: All neonates (N = 151) accepted the uncoated mini-tablet as well as the syrup (both formulations 100%; 95% CI 97.6%-100.0%; primary objective). The level of swallowability of uncoated mini-tablets was not inferior (P < .0001), in fact even higher (difference in proportions 10.0%; 95% CI 1.37%-19.34%; P = .0315) compared with syrup. Both pharmaceutical formulations were well tolerated, and in none of the 151 neonates, serious adverse events occurred; particularly none of the neonates inhaled or coughed in either of the formulations. CONCLUSIONS: The administration of uncoated mini-tablets proved to be a valuable alternative to syrup for term neonates. Our data on neonates close the age gap of prior findings in toddlers and infants: uncoated mini-tablets offer the potential of a single formulation for all age groups. These findings further shift the paradigm from liquid toward small-sized solid drug formulations for children of all age groups, as the World Health Organization proposes.

Favorable acceptance of mini-tablets compared with syrup: a randomized controlled trial in infants and preschool children.

OBJECTIVE: To evaluate acceptability of 2 mm solid dosage forms (mini-tablets) as an alternative administration modality in young children in comparison with syrup. STUDY DESIGN: Three hundred six pediatric in- and outpatients aged 6 months-5 years (51 in each of 6 age groups) were recruited. An open, randomized cross-over study was conducted to compare acceptability and capability to swallow 2 mm uncoated or coated mini-tablets vs 3 mL syrup. RESULTS: In the overall patient population of 306 children, the acceptability of uncoated mini-tablets was superior to syrup (difference in proportions 14.8%, 95% CI 10.2-19.4; P < .0001). In line with this finding, the level of capability to swallow was higher for uncoated mini-tablets compared with syrup as well (difference in proportions 12.3%, 95% CI 5.4-19.3; P = .0008). All 3 pharmaceutical formulations were well tolerated, and none of the 306 children inhaled or coughed because of the syrup or the uncoated mini-tablet; only 2 of the 306 children (both in age group 0.5-1 year) coughed because of the coated mini-tablet, in both cases without clinical relevance. CONCLUSIONS: Mini-tablets are a valuable alternative to syrup for children 6 months-6 years of age and are more acceptable compared with liquid formulation. Regulatory bodies such as Food and Drug Administration and European Medicine Agency are encouraged to take our data into account for guideline updates and future drug approval processes.

Acceptance of uncoated mini-tablets in young children: results from a prospective exploratory cross-over study.

OBJECTIVE: To explore the acceptance of uncoated drug-free mini-tablets 2 mm in diameter in children aged 0.5-6 years and their ability to swallow the mini-tablets. METHODS: 60 children aged 0.5-6 years (10 subjects per year of life) were enrolled in our prospective, open random, two-way cross-over exploratory pilot study. The children were administered either an uncoated drug-free mini-tablet 2 mm in diameter with a beverage of their choice or 3 ml of glucose syrup 15% followed by the other formulation. Deglutition was visually assessed for the two different dosage forms using a predefined criteria list. RESULTS: The study hypothesis was that children would accept the liquid formulation better than the solid mini-tablets. Surprisingly, the authors found that the acceptance of the mini-tablets, defined as immediate swallowing or chewing first with subsequent swallowing, was higher or at least equal to that of the syrup. Very young children (6-12 months) were fully capable of swallowing the mini-tablets and may even accept them better than the sweet liquid formulation. Some children aged between 2 and 4 years chewed the tablets before swallowing, but still accepted them quite well. The acceptance rate of the mini-tablets in the different age groups was much higher than expected. CONCLUSIONS: Uncoated mini-tablets seem to be a very promising alternative to liquid formulations and could be used at an earlier age in paediatric drug therapy than previously anticipated.
