1. 1. Molecular Mechanisms Influencing the Performance of Amorphous Formulations for Poorly Water-Soluble Drugs

   Författare :Khadijah Edueng; Christel Bergström; Denny Mahlin; Michael Hageman; Uppsala universitet; []
   Nyckelord :Amorphous formulation; crystallisation; supersaturation; glass-forming ability; physical stability; glass stability; spray-dried solid dispersion; dissolution; promiscuous glass former; poorly-soluble drug; solid-to-solid; solution-mediated; particle-associated; Farmaceutisk vetenskap; Pharmaceutical Science;

   Sammanfattning : Crystallisation is a concern for amorphous formulation because it compromises the solubility-enhancing benefit gained from amorphisation. Traditionally, amorphous formulation had been designed primarily based on trial-and-error approach. LÄS MER

   Sammanfattning : ZSM-5 is an aluminosilicate zeolite with high Si/Al ratio with suitable properties for catalysis, ion exchange, adsorption and membrane applications. The main goal of this thesis was to study the growth of ZSM-5 zeolite crystals from inexpensive natural sources of silica and alumina, as well as n-butylamine (NBA) as a low-cost structure directing agent.
