Pharmaceutical Formulation Development Utilizing Hot Melt Extrusion And Other Techniques For Development Of Immediate And Controlled Release Dosage Forms, Noorullah Naqvi Mohammed

Electronic Theses and Dissertations

Hot melt extrusion (HME) was evaluated as a processing technology for the manufacture of immediate as well as controlled release formulations for oral delivery of two model compounds. For immediate release applications lower molecular weight grades of Hydroxypropyl cellulose polymers, EF and ELF, were utilized as carrier matrices to form solid solutions of a poorly soluble compound, Ketoprofen (KPR). Thermal characterization techniques were used to confirm thermal stability, miscibility and setting up processing conditions for extrusion. Extruded matrices were pelletized to be filled into pellets or further milled and compressed into tablets. Pellets exhibited a carrier dependent release with ELF …
