Thermoplastic polyurethanes for the manufacturing of highly dosed oral sustained release matrices via hot melt extrusion and injection molding

Ethylene Vinyl Acetate as Matrix for Oral Sustained Release Multiple-unit Dosage Forms Produced via Hot-melt Extrusion

Hot Melt Extrusion Technique

Various approaches have been adopted to address this including preparation of solid dispersions and solid solutions. Hot-melt extrusion is an efficient technology for producing solid molecular dispersions with considerable advantages over solvent-based processes such as spray drying and co-precipitation. Hot-melt extrusion has been demonstrated to provide sustained, modified, and targeted drug ...

Hot-melt extrusion of polyvinyl alcohol for oral immediate release applications.

The primary purpose of this study was to process partially hydrolyzed PVOH grades (degree of hydroxylation (DH): 33-88%) via HME and to evaluate them as carrier for oral immediate release dosage forms in order to improve the release rate of poorly water soluble drugs (i.e., HCT and CEL) via the formulation of solid dispersions. PVOH grades (DH >70%) were able to solubilize HCT and CEL up to 15%...

Development of extended release matrices of rifampicin using hot melt extrusion technique

Article history: Received on: 12/06/2013 Revised on: 16/09/2013 Accepted on: 17/10/2013 Available online: 31/10/2013 Tuberculosis has metamorphosized over the decades from drug resistant to multidrug resistant to the lethal extensively drug resistant forms lately. With scarce newer anti-TB drugs emerging, there is a pressing need to ameliorate the current treatment therapy by modulating the for...

Hot-Melt Extrusion Technique: A Review

Hot-melt extrusion is one of the most widely applied processing technologies in the plastic, rubber and food industry. Today this technology has found its place in the array of pharmaceutical manufacturing operations. Melt extrusion process are currently applied in the pharmaceutical field for the manufacture of a variety of dosage forms and formulations such as granules, pellets, tablets, supp...
