**6.4 Solid dispersion extrusion**

The method entails incorporating a solid dispersion of the drug into a melted polymer solution to load the medication. To make a solid dispersion, the medication is dissolved in a suitable liquid solvent and then added to a melt of a suitable polymer that is attainable below 70°C without removing the liquid solvent. Finally, the dyes are used to form the solid dispersions into films [65].
