Drug nanocomposites and amorphous solid dispersions (ASDs) are two major formulation platforms used for the bioavailability enhancement of BCS Class II drugs. The major drawback of nanocomposites is their inability to attain high drug supersaturation during in vitro (<50% relative supersaturation) and in vivo dissolution. On the other hand, formulating an amorphous solid dispersion (ASD) with high drug loading (>20%) that releases drug rapidly, while generating and maintaining high supersaturation over at least three hours is challenging. The goal of this thesis is to develop a fundamental understanding of the impact of anionic surfactants–polymers on in vitro drug release from nanocomposites and ASDs, while addressing the above challenges. To achieve this goal, the following objectives are set: (1) compare griseofulvin …50%>

Electronic Theses and Dissertations
New drug product development is a time consuming and costly process. One of the significant challenges is the poor aqueous solubility of many active pharmaceutical ingredients (APIs). Among those techniques, hot-melt extrusion(HME) is optimal for pharmaceutical solid dispersion development because of it free of using an organic solvent, easy scale up, and suitable for continuous processing with ensured optimal quality control.
