  1. 1. Improved Molecular Understanding of Lipid-Based Formulations : for Enabling Oral Delivery of Poorly Water-Soluble Drugs

    Författare :Linda C. Alskär; Christel Bergström; Brendan Griffin; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; lipid-based formulation; poorly water-soluble drug; solubility prediction; molecular properties; lipid digestion; precipitation; solid state; intestinal solubilization; in vitro in vivo correlation IVIVC ; coadministration; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : The majority of emerging drug candidates are not suited for conventional oral dosage forms, as they do not dissolve in the aqueous environment of the gastrointestinal (GI) tract. Consequently, a large number of enabling formulation strategies have emerged. LÄS MER

  3. 2. 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

  4. 3. Novel and refined small-scale approaches to determine the intrinsic dissolution rate of drugs

    Författare :Sara B. E. Andersson; Göran Alderborn; Göran Frenning; Peter Langguth; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dissolution; intrinsic dissolution rate; poorly water-soluble compounds; single particle dissolution; solubility; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : Many drugs are administered as crystalline particles compressed into tablets and taken orally. When the tablet reaches the gastrointestinal tract, it disintegrates and the drug particles dissolve in the gastrointestinal fluid. The dissolved molecules are absorbed across the intestinal membranes into the bloodstream to reach their target sites. LÄS MER

  5. 4. Additive Manufacturing and Mesoporous Materials for Pharmaceutical Applications

    Författare :Christos S. Katsiotis; Ken Welch; Jonas Lindh; Maria Stromme; Ryan Donnelly; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive Manufacturing; Fused Deposition Modelling; Semi Solid extrusion; Mesoporous materials; Poorly water soluble drugs; Drug delivery; Teknisk fysik med inriktning mot nanoteknologi och funktionella material; Engineering Science with specialization in Nanotechnology and Functional Materials;

    Sammanfattning : Additive Manufacturing (AM), over the past decade, has evolved into a versatile technology with significant applications in pharmaceutical research. This technology enables the production of drug formulations tailored to individual patients, offering customization in both dosage and dissolution profiles. LÄS MER

  7. 5. Water-swelling tablets based on hydrophobically modified poly(acrylic acid) - Effects of amphiphiles on swelling and drug release

    Författare :Patrik Knöös; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Drug deliver; Controlled release; Hydrophobically modified polymers; Surfactant-polymer interactions; Poorly soluble drug;

    Sammanfattning : An important issue within the pharmaceutical world today is the increasing number of poorly soluble drugs. These often show a low bioavailability and a susceptibility to varying conditions in the intestine. LÄS MER
