Compared to single-unit dosage forms, oral multiparticulate drug-delivery systems (e.g. pellets, granules) offer biopharmaceutical advantages in terms of a more even and predictable distribution and transportation in the gastrointestinal tract. There are different pelletization and granulation techniques available to prepare drug loaded spherical particles or granules. Extrusion Spheronization ...
The aim of this study was to develop a multilayer (core/coat) dosage form via co-extrusion, the core providing sustained drug release and the coat immediate drug release. In this study polymers were selected which can be combined in a co-extruded dosage form. Several thermoplastic polymers were hot-melt extruded and evaluated for processability and macroscopic properties (surface smoothness, di...
Introduction: The formation mechanism for regions of chaotic terrain on Europa is the subject of much debate. Several models have been proposed to account for these disrupted areas of Europa's surface including melting through the ice shell by a concentrated heat source in the underlying ocean [1,2], coalescence of solid-state diapirs [3], extrusion of warm ice onto the surface [4], and melting...
