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.
Child-appropriate drug formulations are mandatory for an efficient and safe drug therapy in children. Since the implementation of supportive legislations development of novel drug formulations has significantly been enforced despite the fact that children are a heterogeneous group of patients with varying needs according to age, maturation and disease. Areas covered: In this review, recent advances and current strategies are evaluated how to overcome the specific hurdles in pediatric drug development. For cardiovascular diseases as an example, EMA's decisions on pediatric investigation plans (PIPs) have been evaluated. New developments with innovative platform technologies such as mini-tablets and orodispersible preparations have been identified indicating a clear shift from liquid preparations to small-sized solid (multiparticulate) or orodispersible dosage forms. Reasons for this shift of paradigm are discussed. Expert opinion: Innovative platform technologies for solid drug dosage forms such as mini-tablets, orodispersible tablets or film preparations will continue to conquer the pharmaceutical market. Still, there are some major issues to be resolved, e.g. how to ensure quality of the new dosage forms and dose accuracy in flexible dosing, but the governmental incentives will continue to accelerate development of pediatric medicines and will bridge the still existing gaps in the near future.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
