Special Issue Information

Dear Colleagues,

The development of pediatric drug formulations is challenging since they must be adapted to children’s needs depending on their age, requiring constant dosing adjustments according to their weight and physiological conditions, as well as requiring different administration routes and dosage forms. The lack of specific formulations results in a large use of extemporaneous preparations leading to poor dosing accuracy and the need to develop suitable dosage forms.

Acceptability, namely, the ability and willingness of the patient to use and their caregiver to administer the medicine as intended, is the main issue to consider in the development of pediatric formulations to assure adherence to therapy. Other critical issues are the stability of the formulations and the choice of suitable excipients for a safe and effective treatment.

Original research papers, communication papers and review articles focused on formulation strategies for the development of suitable and effective pediatric formulations are welcome in this Special Issue.

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.

Paediatric infectious diseases contribute significantly to global health challenges. Conventional therapeutic interventions are not always suitable for children, as they are regularly accompanied with long-standing disadvantages that negatively impact efficacy, thus necessitating the need for effective and child-friendly pharmacotherapeutic interventions. Recent advancements in drug delivery technologies, particularly oral formulations, have shown tremendous progress in enhancing the effectiveness of paediatric medicines. Generally, these delivery methods target, and address challenges associated with palatability, dosing accuracy, stability, bioavailability, patient compliance, and caregiver convenience, which are important factors that can influence successful treatment outcomes in children. Some of the emerging trends include moving away from creating liquid delivery systems to developing oral solid formulations, with the most explored being orodispersible tablets, multiparticulate dosage forms using film-coating technologies, and chewable drug products. Other ongoing innovations include gastro-retentive, 3D-printed, nipple-shield, milk-based, and nanoparticulate (e.g., lipid-, polymeric-based templates) drug delivery systems, possessing the potential to improve therapeutic effectiveness, age appropriateness, pharmacokinetics, and safety profiles as they relate to the paediatric population. This manuscript therefore highlights the evolving landscape of oral pharmacotherapeutic interventions for leading paediatric infectious diseases, crediting the role of innovative drug delivery technologies. By focusing on the current trends, pointing out gaps, and identifying future possibilities, this review aims to contribute towards ongoing efforts directed at improving paediatric health outcomes associated with the management of these infectious ailments through accessible and efficacious drug treatments.
