  1. 6. Pharmacokinetic drug-drug interactions in the management of malaria, HIV and tuberculosis

    Författare :Doaa Elsherbiny; Ulrika Simonsson; Mats Karlsson; Lars Ståhle; Uppsala universitet; []
    Nyckelord :Pharmacokinetics Pharmacotherapy; Pharmacokinetics; Drug-drug interactions; Cytochrome P-450; Artemisinin antimalarials; Nevirapine; Lopinavir; Rifampicin; NONMEM; Farmakokinetik Farmakoterapi;

    Sammanfattning : Malaria, Human Immunodeficiency Virus (HIV) and tuberculosis (TB) are global health problems having their worst situation in sub-Saharan Africa. Consequently, concomitant use of antimalarial, antiretroviral and antitubercular drugs may be needed, resulting in a potential risk of drug-drug interactions. LÄS MER

  2. 7. Renal dysfunction in orthopaedic surgery - with special reference to drug effects in the elderly

    Författare :Görel Nergelius; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthopaedics; Surgery; protein HC; IgG; albumin; pharmacokinetics; diclofenac; clearance; elderly; penicillin; isoxazolyl; tubular; glomerular; arthroplasty; exercise; traumatology; Kirurgi; ortopedi; traumatologi; Anaesthesiology; intensive care; Anestesiologi; intensivvård;

    Sammanfattning : Total hip replacement (THR) is a common procedure, generally performed in elderly persons. Previous studies indicated that the use of isoxazolyl penicillins could induce a transient post-operative renal dysfunction in these patients. LÄS MER

  3. 8. Chemotherapy in Childhood Acute Lymphoblastic Leukemia : In vitro cellular drug resistance and pharmacokinetics

    Författare :Britt-Marie Frost; Henrik Schröder; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstetrics and gynaecology; cytotoxicity; drug resistance; pharmacokinetics; Acute lymphoblastic leukemia; childhood; in vitro assay; vincristine; doxorubicin; Down`s syndrome; CHS 828.; Obstetrik och kvinnosjukdomar; Obstetrics and women s diseases; Obstetrik och kvinnosjukdomar; pediatrik; Pediatrics;

    Sammanfattning : The aims of the studies described in this thesis were to investigate the pharmacokinetics of and cellular resistance to chemotherapy as causes of treatment failure in childhood acute lymphoblastic leukemia (ALL).Leukemic cells from 370 children with newly diagnosed ALL were tested by the Fluorometric Microculture Cytotoxicity Assay to measure their resistance to each of ten standard cytotoxic drugs.

  4. 9. In vivo Pharmacokinetics of Two New Thrombin Inhibitor Prodrugs : Emphasis on Intestinal and Hepatobiliary Disposition and the Influence of Interacting Drugs

    Författare :Elin Matsson; Hans Lennernäs; Lars Knutson; Ulf Eriksson; Kim Brouwer; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Direct thrombin inhibitors; prodrugs; ximelagatran; AZD0837; erythromycin; ketoconazole; drug-drug interactions; hepatobiliary transport; biliary clearance; ATP-binding cassette; ABC transporters; solute carriers; SLC transporters; CYP3A4; Biopharmacy; Biofarmaci; Biopharmaceutics; Biofarmaci;

    Sammanfattning : Biliary excretion is an important elimination route for many drugs and metabolites. For such compounds, it is important to know the extent of excretion and drug exposure in the bile, e.g., for the risk assessment of drug interactions, liver toxicity and the effects of genetic variants.

  5. 10. Deposition and absorption of inhaled drugs

    Författare :Eva Bondesson; Malmö Klinisk fysiologi och nuklearmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tomografi; radiologi; Klinisk fysiologi; medical instrumentation; tomography; radiology; Clinical physics; technetium-99m; radionuclide imaging; radioactive aerosol; powder inhaler; pharmacokinetics; mucociliary clearance; lung deposition; gamma scintigraphy; inhalation; deposition modelling; drug absorption; absorption enhancer; aerosol; medicinsk instrumentering; Physiology; Fysiologi;

    Sammanfattning : Main objectives of this thesis were to evaluate a gamma scintigraphic method used to quantify drug aerosol deposition in the lung, to investigate the influence of two aerosol inhalation parameters on the distribution of inhaled dry powder within the airways, to assess pulmonary absorption kinetics and bioavailability of an inhaled hydrophilic solute in relation to site of deposition, and to assess the influence of a surface active agent (sodium taurocholate, a bile salt) on the deposition and absorption of an inhaled hydrophilic solute. Repeated planar gamma scintigraphy was found to provide the same information on total pulmonary drug deposition as an independent method that involved assessments of urinary drug recovery after blockage of gastrointestinal drug absorption when all of the critical parts of the methodological procedures were accurately and meticulously executed.
