Within this image, a profound question mark takes shape. It is constructed by various tablets, each distinguished by its unique size and shape. This visual metaphor delves into the complexities of patient-centric drug development for older adults and geriatric patients. The tablets, with their varied dimensions, artfully convey the nuanced impact of size and shape on swallowability, visual perception, handling, and consequently on the overarching aspect of patient acceptability.

This composition covers a critical healthcare question, revolving around the design of solid oral dosage forms tailored to the needs and challenges of aging individuals. The question mark draws attention to the multifaceted dimensions of patient acceptability. It serves as a visual narrative, stimulating discussion on optimizing medication design for increased patient convenience and adherence in the aging demographic. To get closer to an answer to this question of appropriate tablet sizes and shapes for older adults and geriatric patients a clinical study was performed within the scope of AGePOP. Applying the knowledge gained from this study will allow for the design of patient-centric drug products tailored to the needs of the main group of medication users.
