Currently, the compressed tablet and its oral administration is the most popular drug delivery modality in medicine. The accurate porosity and tensile strength characterization of a tablet design is vital for predicting its performance such as disintegration, dissolution, and drug-release efficiency upon administration as well as ensuring its mechanical integrity.
This study focuses on understanding the physicochemical principles for the preparation of high drug-loaded microgranules with a desired size distribution and mechanical properties. Mesalamine was selected as a model drug, and microgranulation was performed using an extruder and a conical screen mill.
