Chitosan‐based spray‐dried solid dispersions of apigenin in a 3D printable drug delivery system

Journal of Applied Polymer Science, Volume 142, Issue 1, January 5, 2025.
Schematic representation of chitosan‐based apigenin spray‐dried solid dispersions (SDSDs) preparation. Abstract This study aims to develop chitosan‐based apigenin (AGN) spray‐dried solid dispersions (SDSDs) within a 3D pill. AGN SDSDs were prepared using 1:1 (AC1), 1:1.5 (AC2), and 1:2 (AC1) apigenin/chitosan weight ratios.
