Based on the research status and division issues of drug packaging, the work aims to study the tablet division packaging through service design methodology and inclusive design principles to improve the inclusivity of tablet division packaging. To address the safety, convenience, and compatibility issues of tablet division packaging in medication needs of divided dose, patient interviews were conducted to understand their current medication status and needs. Personas and journey maps of service design methodology were used to construct different user models and explore touchpoints, pain points and opportunities. Finally, the inclusive design of divided blister packaging was carried out according to the touchpoints, and it was evaluated by control test, usability scale and user satisfaction questionnaire. Through the service design method, the dose demand of patients taking tablets in the whole process was explored. The deduced divided dose blister packaging design was more inclusive, which could meet the dose demand of patients taking tablets and improve the satisfaction of their medication experience. This study can effectively address the tablet division needs of patients and improve their medication experience satisfaction based on the inclusive design principles and of service design methodology, which provides practical evidence for the development of inclusive design in drug packaging.
