Feasibility of AquasolveTM HPMC-AS Lg via Hot-melt Extrusion: Effect of Pressurized CO2 on Physico-mechanical Properties
… hot-melt extrusion, and to examine the effect of pressurized carbon dioxide (P-CO2) on the physico-mechanical properties of Efavirenz (EFA)-loaded extrudates (EXT). EFA is as a poorly water-soluble drug and HPMC-AS LG was chosen as a carrier for this study. To optimize the process parameters and …

Synthesis of Functionalized Sustainable Polyesters via Controlled Ring-opening Polymerization of O-carboxyanhydrides
… complex at room temperature in the absence of pressurized CO2 (Chapter 6). Kinetic studies showed that the first stage of the process, ring-opening polymerization of the O-carboxyanhydrides, exhibited zero-order kinetics, suggesting that the polymerization rate was independent of monomer …

Development and Characterization of Sustained-Release Formulations via Novel Hot Melt Extrusion Techniques
… Part of this research project focus on injecting pressurized carbon dioxide (P-CO2) gas during the HME process. These combined techniques have an additional advantage of being adaptable and portable to a hot melt extruder instrument. The use of HME alongside with other techniques (P-CO2 or co …
