The aim of the present investigation was to understand the swelling behaviour of HPMC and PEO-based matrices and to evaluate the impact of porosity on the swelling kinetics. It was noticed that the HPMC has higher swelling rates but both undergo diffusion oriented swelling mechanism.

Amorphous solid dispersions (SDs) are considered as one of the most effective strategies for the formulation of poorly water-soluble compounds. The active compound is dispersed in an inert carrier composed of a polymer and active excipients. Since the drug is amorphous, there is typically an increase in apparent solubility as well as dissolution rate. Various methods are employed for manufacturing of SDs, nevertheless, hot-melt extrusion (HME) has become one of the most common process techniques
