  1. 1. Pharmaceutical Nanocomposites : Structure–Mobility–Functionality Relationships in the Amorphous State

    Författare :Joel Hellrup; Denny Mahlin; Göran Alderborn; László Fábián; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; amorphous; pharmaceutical composites; solid state; structure; molecular mobility; spray-drying; freeze-drying; moisture sorption; physical stability; compression; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : Amorphous materials are found in pharmaceutical formulations both as excipients and active ingredients. Indeed, these formulations are becoming an essential strategy for incorporating drugs into well-performing solid dosage forms. LÄS MER

  2. 2. Confidence Predictions in Pharmaceutical Sciences

    Författare :Staffan Arvidsson McShane; Ola Spjuth; Wesley Schaal; Lars Carlsson; Ernst Ahlberg; Stefan Kramer; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; machine learning; QSAR; Conformal prediction; Venn-ABERS; Probabilistic machine learning; Machine learning; Maskininlärning; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : The main focus of this thesis has been on Quantitative Structure Activity Relationship (QSAR) modeling using methods producing valid measures of uncertainty. The goal of QSAR is to prospectively predict the outcome from assays, such as ADMET (Absorption, Distribution, Metabolism, Excretion), toxicity and on- and off-target interactions, for novel compounds.

  3. 3. Application of Artificial Gel Antibodies for the Detection and Quantification of Proteins in Biological Fluids

    Författare :Nasim Ghasemzadeh; Fred Nyberg; Dom M. Desiderio; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmaceutical biochemistry; Farmaceutisk biokemi; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : The molecular-imprinting method has previously been used for the synthesis of artificial gel antibodies, highly selective for various proteins. In present study, we have synthesized artificial gel antibodies against haemoglobin, albumin and different forms of growth hormone with the aim to develop a simple and rapid procedure to measure the concentration of these protein biomarkers in samples of clinical interest.

  4. 4. Process-induced disorder of pharmaceutical materials : Mechanisms and quantification of disorder

    Författare :Samaneh Pazesh; Göran Alderborn; Jonas Berggren; Niklas Sandler; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Milling; Comminution; Powder flow; Amorphisation; Raman spectroscopy; Atomic force microscopy; Plastic stiffness; Elastic stiffness; Pharmaceutical Science; Farmaceutisk vetenskap;

    Sammanfattning : One of the most important prerequisites in the drug development is to attain a reproducible and robust product in terms of its nature, and its chemical and physical properties. This can be challenging, since the crystalline form of drugs and excipients can be directly transformed into the amorphous one during normal pharmaceutical processing, referred to as process-induced amorphisation or process-induced disorder.

  5. 5. Preparation of Pharmaceutical Powders using Supercritical Fluid Technology : Pharmaceutical Applications and Physicochemical Characterisation of Powders

    Författare :Sitaram Velaga; Johan Carlfors; Kristiina Järvinen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; Supercritical fluid; Gas Anti-Solvent; SEDS; Crystallisation; Particle design; Polymorphs; Dry powder inhalation; Solid-state behaviour; Therapeutic proteins; Precipitation; Stability; Recombinant human growth hormone hGH ; Galenisk farmaci; Pharmaceutics; Galenisk farmaci;

    Sammanfattning : The main aim of the thesis was to explore the potential of supercritical fluid (SF) techniques in the field of drug delivery. In particular, the relatively recently developed solution-enhanced dispersion by supercritical fluids (SEDS) technology has been employed in the preparation of particles/powders. LÄS MER
