  1. 6. Developmental Aspects of Drug Transport Across the Blood-Brain Barrier

    Författare :Jörgen Bengtsson; Margareta Hammarlund-Udenaes; Ann-Cathrin Engwall; Sven Björkman; Elizabeth C.M. de Lange; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood-brain barrier; development; active transport; tight junction proteins; microdialysis; recovery; morphine; nitrofurantoin; Bcrp; microarray; real-time PCR; in vitro; in vivo; LC-MS MS; Biopharmacy; Biofarmaci; Pharmacokinetics and Drug Therapy; Farmakokinetik och läkemedelsterapi;

    Sammanfattning : The developmental aspect of drug transport across the blood-brain barrier (BBB) was investigated. Microdialysis was used to study unbound morphine BBB transport at different ages in sheep. An in vitro study was performed to find differentially expressed genes in brain capillary-rich fractions of the brain in rats of different ages. LÄS MER

  3. 7. Translational Aspects of Blood-Brain Barrier Transport and Brain Distribution of Drugs in Health and Disease

    Författare :Sofia Gustafsson; Margareta Hammarlund-Udenaes; Stina Syvänen; Irena Loryan; Danica Stanimirovic; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood-brain barrier; Neurovascular unit; Pharmacokinetics; Neurodegenerative disease; Drug transport; Brain tissue binding; Positron emission tomography; Brain regions; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : A high unmet medical need in the area of CNS diseases coincides with high failure rates in CNS drug development. Efficient treatment of CNS disease is constrained by limited entrance of drugs into the brain owing to the blood-brain barrier (BBB), which separates brain from blood. LÄS MER

  4. 8. Monitoring of antiepileptic drugs using microdialysis : methodological and clinical aspects

    Författare :Martin Lindberger; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : In therapeutic monitoring of antiepileptic drugs (AEDs) the level of unbound drug at the sampling site should ideally equal the unbound concentration at receptor sites. Microdialysis enables direct sampling of the unbound drug concentration and avoids some of the difficulties encountered with ex vivo protein binding. LÄS MER

  5. 9. Microdialysis as a tool in pharmacokinetic-pharmacodynamic studies investigating the brain distribution and effect delay of morphine and morphine-6-glucuronide

    Författare :Marcel René Bouw; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; FARMACI; PHARMACY; FARMACI; Biopharmaceutics; biofarmaci;

    Sammanfattning : The microdialysis technique was developed as a tool for studying the pharmacokinetic and pharmacodynamicrelationships of morphine and morphine-6-glucronide (M6G). Concentrations of unbound drug in blood andbrain were monitored in order to elucidate the origin of the observed delay in antinociceptive effect in rats. LÄS MER

  7. 10. In vitro Pharmacodynamics of Antifungal Agents in the Treatment of Candida Infections

    Författare :Anders Lignell; Jan Sjölin; Elisabeth Löwdin; Mats Kalin; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amphotericin B; antagonism; Candida; human serum; inhibition; interaction; in vitro; kinetic model; pharmacodynamics; pharmacokinetics; posaconazole; protein binding; voriconazole; Infectious diseases; Infektionssjukdomar; Infektionssjukdomar; Infectious Diseases;

    Sammanfattning : Pharmacodynamic studies are important for the optimal use of antimicrobial agents. Combination antifungal therapy may be one method to improve outcome in invasive Candida infections. LÄS MER
