  1. 1. Engineering of Pharmaceutical Particles Modulation of Particle Structural Properties, Solid-State Stability and Tabletting Behaviour by the Drying Process

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jonas Berggren; Göran Alderborn; Graham Buckton; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; particle engineering; microcrystalline cellulose pellets; intragranular porosity; convective drying; tabletting behaviour; spray-dried composite particles; amorphous lactose; PVP; heat and moisture-induced crystallisation; glass transition temperature; Galenisk farmaci; PHARMACY Pharmaceutics; FARMACI Galenisk farmaci; galenisk farmaci; Pharmaceutics;

    Abstract : Relationships between stresses during the drying process, particle structural and functional properties, and particle engineering by the drying process were addressed in this thesis. In the first part, the importance of the drying phase and the effect of the drying rate on the intragranular porosity of microcrystalline cellulose pellets were investigated. READ MORE
