ABSTRACT
The aim of this study is to prepare acetaminophen sustained-release tablets by hot melt extrusion 3D printing technology based on the concept of "Quality by Design" (QbD). Firstly, the failure mode and effect analysis (FMEA) was used to determine the critical process parameters (CPPs), then full-factor experimental design was used to analyze the critical quality attributes (CQAs) and to establish the design space. The results showed that the content of plasticizer, the path spacing and the shell numbers are independent variable for the experimental design. The design space was concluded to be plasticizer content 9%, and the shell number 3-5, the path spacing 1.05-1.2 mm. In this study, 3D printing technology was used to prepare acetaminophen sustained-release tablets in accordance with the concept of QbD, which improved the durability of the process and ensured the uniform and controllable quality of the preparation and also provided experimental basis for personalised medicine.
