  1. 21. 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. 22. Advanced Methods for Evaluation of the Performance of Complex Drug Delivery System

    Författare :Caroline Alvebratt; Christel Anna Sofia Bergström; Maria Strömme; Caitriona O'Driscoll; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amorphous solid dispersion; coadministration; digestion; dissolution; drug absorption; enabling formulation; in vitro assay; lipid-based formulation; mesoporous carrier; supersaturation; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : Low oral bioavailability of drugs originating from poor aqueous solubility is a common issue in drug development. Various enabling formulations have been presented to circumvent this limitation, many making use of supersaturation. In these, the drug is delivered to the gastro-intestinal lumen in a high energy state e.g. LÄS MER

  4. 23. 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. 24. Pharmacometric tools to support translational drug development

    Författare :Rami Ayoun Alsoud; Ulrika S. H. Simonsson; Michael Lyons; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; drug development; pharmacometrics; pharmacokinetics; pharmacodynamics; non-linear mixed effect models; tuberculosis; dose selection; interspecies scaling; pediatric trials; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : The use of model-informed drug development has been shown to save significant costs and improve decision making early in the drug development process. The work in this PhD thesis aimed to employ pharmacometric tools to support translational drug development from the preclinical to the late clinical stages. LÄS MER

  7. 25. Garnishing the smorgasbord of pharmacometric methods

    Författare :Henrik Bjugård Nyberg; Andrew Hooker; Johannes Schropp; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacometrics; pharmacokinetics; saddle points; nonidentifiability; modelling and simulation; tuberculosis; ethionamide; bioequivalence; model-integrated evidence; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : The smorgasbord of methods that we use within the field of pharmacometrics has developed steadily over several decades and is now a well-laid-out buffet. This thesis adds some garnish to the table in the form of small improvements to the handling of certain problems. LÄS MER
