Assessment Of A Marine Polysaccharide For Use As Excipient In Pharmaceutical Hot-Melt Extrusion, Qing Ye

Theses

Pharmaceutical Hot Melt Extrusion (HME) is currently investigated by both industry and academia as a method for manufacturing solid oral dosages with improved bioavailability of poorly-water soluble active pharmaceutical ingredients (APIs) and control drug release of water-soluble APIs. Although HME is traditionally utilizing synthetic polymers to produce such dosages, biopolymers constantly gain ground by virtue of renewability, biocompatibility and in some cases biodegradability. In this work, the possibility of using Keltone, a marine polysaccharide derived from brown seaweed, as a polymeric excipient for pharmaceutical HME is explored. Keltone is insoluble in acidic pH and soluble in basic pH, therefore making …

Dispersion And Dissolution Kinetics Of Api Particles In Pharmaceutical Hot Melt Extrusion, Wang Zhan

Theses

Pharmaceutical Hot Melt Extrusion (HME) is essentially a special case of polymer compounding. The elementary steps involved in traditional plastics melt processing are handling of particulates, melting, dispersive and distributive mixing, devolatilization and stripping, and finally pressurization and pumping. However, for pharmaceutical HME, the dissolution of the API (Active Pharmaceutical Ingredient) is an additional and very important elementary step, along with the melting of the polymeric excipient that precedes it, and mixing which accelerates the dissolution process. A major concern in pharmaceutical HME is the thermal degradation of the API. To avoid overexposure of API to heat while ensuring complete …

Warp & Weft, Maggie Pinke

Theses

There are two distinct directional strands used in weaving, the warp and the weft. Weaving functions as a rich metaphor for language and story telling, stretching across time and cultures. Like both photography and spoken language, it contains an assumption of memory and the ephemeral. Cloth wears thin with use, while images on paper, though temporarily captured, fade with time, and voices disappear once spoken. Building a body of work that examines created and recovered experience through text and image has allowed me to take the necessary steps backward and discover links between events and places previously unexplored.
