This study introduces a novel additive manufacturing method for creating personalized medicine doses. The process precisely formulates crystalline solid dispersions (CrySoD) with customizable drug strengths for tailored pharmaceutical therapy.
Area of Science:
- Pharmaceutical Manufacturing
- Personalized Medicine
- Materials Science
Background:
- Flexible solid dosage manufacturing is crucial for personalized medicine.
- Current platforms require advanced precision dosing capabilities.
Purpose of the Study:
- To develop a solution-based additive manufacturing platform for individualized solid dosage forms.
- To demonstrate precise dose control using a model-informed algorithm.
Main Methods:
- Utilized additive manufacturing to create crystalline solid dispersions (CrySoD).
- Employed evaporative antisolvent crystallization of warfarin sodium isopropanol (WS-IPA) within a polymer matrix (PEG).
- Controlled critical process parameters (temperature, concentration, antisolvent composition).
Main Results:
- Achieved precise dosing in increments as small as 0.2 mg.
- Manufactured WS-IPA CrySoD capsules meeting key performance metrics (dissolution) comparable to commercial tablets (Coumadin®).
- Successfully obtained the commercial crystalline solid form of WS-IPA.
Conclusions:
- The study provides a generalizable proof-of-concept for a model-informed solid dosage formulation platform.
- This approach enables process intensification for personalized pharmaceutical therapy.
- Results support further research in personalized drug substances, regulatory science, and technoeconomic analysis.
