Special Issue Information

Dear Colleagues,

The field of pharmaceutics continually evolves to meet the unique needs of diverse populations, including pediatrics, geriatrics, and veterinary medicine. The demand for customized pharmaceutical solutions tailored to specific requirements is continually rising. From developing age-appropriate formulations for children to addressing the complexities of medication management in the elderly, and catering to the distinct physiological characteristics of animals, the pursuit of innovation in customized pharmaceutics remains a challenge. Advances in the field comprise, for example, nanotechnology, 3D printing and taste-masking technologies for enhanced palatability. This Special Issue aims to explore the latest developments in this dynamic field, emphasizing the importance of addressing the diverse needs of pediatric, geriatric, and veterinary patients through innovative pharmaceutical approaches.

Background/Aims: This preference study aimed to identify the maximum number of mini-tablets of two different sizes that children and adolescents would be willing to take, and parents, nurses, and pediatricians would be willing to administer to children and adolescents. Methods: A total of 336 participants (24 per cohort) were stratified into 14 cohorts: Acutely and chronically sick children/adolescents aged 6–<12 years (y) and 12–<18 y, parents of acutely and chronically sick children/adolescents aged 0–<2 y, 2–<6 y, 6–<12 y, and 12–<18 y, nurses, and pediatricians. After participants were shown seven different numbers of 2 and 3 mm mini-tablets, they were asked to assess the maximum number acceptable for short-, middle-, and long-term treatment using cohort-specific questionnaires. Results: Within all groups and treatment durations, the specified maximum accepted number of 2 mm mini-tablets was higher than the number of 3 mm mini-tablets. The maximum number of mini-tablets acceptable to the participants increased with increasing age of the children and ranged from 40–500 (30–400) for the 2 mm (3 mm) mini-tablets. With increasing duration of treatment, a lower maximum number of mini-tablets was considered tolerable. Chronically sick children were willing to take higher numbers of mini-tablets than acutely sick children. The maximum accepted numbers of mini-tablets specified by pediatric patients, parents, and healthcare professionals were similar for each age group; however, pediatricians consistently specified slightly higher numbers of mini-tablets than parents and nurses. Conclusions: The study demonstrated that even a high number of mini-tablets would be well-accepted by children during middle- or long-term treatment. Full article

Background/Objectives: This study focused on developing an organic solvent-free formulation of phytantriol-based cubosomes for nifedipine delivery. It assessed the physicochemical properties and in vitro administration performance in pediatric nasogastric tubes and preliminarily evaluated toxicity in a brine shrimp lethality model. Methods: The nanocarrier formulation was characterized in terms of the particle size and drug release properties and was compared with extemporaneous formulations prepared using nifedipine tablets in flow rate tests through pediatric feeding tubes. The recovery efficiency was evaluated across different tube sizes and rinsing volumes. A preliminary toxicity study was conducted using a brine shrimp lethality model. Results: Compared with nifedipine tablets, the nanocarrier formulation demonstrated favorable physicochemical properties, including controlled release and superior flow rates, in the pediatric tubes. Full recovery of the nifedipine content was achieved with the nanocarrier formulation, whereas extemporaneous formulation of the nifedipine recovery depended on the tube dimensions and rinsing protocols. Conclusions: Compared with the traditional formulations, the nanocarrier formulation represents a promising alternative for administering nifedipine via pediatric feeding tubes, offering an enhanced administration recovery.

Background/Objectives: Medicine acceptability is crucial for paediatric drug development, yet its assessment remains challenging due to the multifaceted nature of sensory attributes like taste, smell, and mouthfeel. Traditional methods of acceptability evaluation often involve complex questionnaires and lack standardisation, leading to difficulties in a comparative analysis across studies. This study aimed to develop a simplified, standardised approach for assessing medicine acceptability introducing the Net Promoter Score (NPS) framework to derive a Medicine Acceptability Score (MAS). Methods: A retrospective analysis was conducted using taste assessment data from nine paediatric formulations across four studies. The MAS was calculated by identifying an optimal range for categorising participant responses, which encapsulated diverse sensory attributes into a single metric. Validation was performed across various age groups and different formulations to test the reliability and discriminatory power of MAS. Results: The MAS effectively discriminated between acceptable and unacceptable formulations, providing a practical tool for formulation development. Conclusions: The MAS offers a novel, standardised metric for evaluating paediatric medicine acceptability, addressing key limitations of traditional methods. Future studies are recommended to refine the MAS model through the establishment of benchmark scores for chronic and acute medications, thereby standardising acceptability assessment of medicines across the pharmaceutical industry.

Three-dimensional printing technology is transforming pharmaceutical manufacturing by shifting from conventional mass production to additive manufacturing, with a strong emphasis on personalized medicine. The integration of bioinks and AI-driven optimization is further enhancing this innovation, enabling drug production with precise dosages, tailored drug-release profiles, and unique multi-drug combinations that respond to individual patient needs. This advancement is significantly impacting healthcare by accelerating drug development, encouraging innovative pharmaceutical designs, and enhancing treatment efficacy. Traditional pharmaceutical manufacturing follows a one-size-fits-all approach, which often fails to meet the specific requirements of patients with unique medical conditions. In contrast, 3D printing, coupled with bioink formulations, allows for on-demand drug production, reducing dependency on large-scale manufacturing and storage. AI-powered design and process optimization further refine dosage forms, printability, and drug release mechanisms, ensuring precision and efficiency in drug manufacturing. These advancements have the potential to lower overall healthcare costs while improving patient adherence to medication regimens. This review explores the potential, challenges, and environmental benefits of 3D pharmaceutical printing, positioning it as a key driver of next-generation personalized medicine. Full article
