  1. 1. Characterization of parameters influencing intracellular bioavailability and prediction of intracellular drug exposure

    Författare :Andrea Treyer; Per Artursson; Gert Fricker; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intracellular drug bioavailability; unbound drug concentration; drug disposition; ADME; drug transport; drug metabolism membrane partitioning; phospholipid; drug-drug interaction; antisense oligonucleotide; cell-penetrating peptide; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : This thesis work investigates factors influencing intracellular drug disposition. An experimental method for measurement of intracellular bioavailability (Fic), was used throughout. Fic is defined as the ratio between the unbound drug concentration inside the cell and the compound concentration in the cell exterior. LÄS MER

  3. 2. Proteomics-informed analysis of drug disposition in the human liver and small intestine

    Författare :Christine Wegler; Per Artursson; Pär Matsson; Tommy B Andersson; Manthena Varma; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; proteomics; protein concentration; drug disposition; drug transport; drug metabolism; human small intestine; human liver; human hepatocytes; human liver microsomes; inter-individual variability; drug clearance; obesity; prediction model; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : Orally administered drugs are absorbed in the intestine and generally metabolized in the liver. Therefore, understanding factors determining drug distribution and elimination in these tissues is important. LÄS MER

  4. 3. Proteomic and Functional Analysis of In Vitro Systems for Studies of Drug Disposition in the Human Small Intestine and Liver

    Författare :Magnus Ölander; Per Artursson; Pär Matsson; Edward L. LeCluyse; Volker Lauschke; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; proteomics; drug disposition; ADMET; drug transport; drug metabolism; hepatotoxicity; small intestine; liver; caco-2; human hepatocytes; cryopreservation; apoptosis; liver zonation; non-parenchymal cells; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : To reach the bloodstream, an orally administered drug must be absorbed through the small intestine and avoid extensive clearance in the liver. Estimating these parameters in vitro is therefore important in drug discovery and development. LÄS MER

  5. 4. Antidepressant drug effects in vivo: Focus on pharmacokinetic and pharmacodynamic responses in different experimental paradigms

    Författare :Cecilia Wikell; Avdelningen för klinisk kemi och farmakologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; portacaval shunt; pharmacokinetics; pharmacodynamics; hepatic encephalopathy; enantiomers; drug safety; drug disposition; citalopram; antidepressants; brain microdialysis; behaviour; venlafaxine; Pharmacological sciences; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi;

    Sammanfattning : Pharmacokinetic and pharmacodynamic activities of the antidepressants venlafaxine (VEN) and citalopram (CIT) were investigated in the portacaval shunted (PCS) rat, a model of chronic hepatic encephalopathy (HE), and normal/control rats. The levels of VEN in serum and brain were higher in PCS rats than in controls after a single injection and chronic treatment with VEN (10 mg/kg). LÄS MER

  7. 5. Biopharmaceutical Evaluation of Intra-arterial Drug-Delivery Systems for Liver Cancer : Investigations in healthy pigs and liver cancer patients

    Författare :Elsa Lilienberg; Hans Lennernäs; Erik Sjögren; Niklas Axén; Helen M. Burt; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; in vivo release; drug delivery systems; local delivery; drug disposition; doxorubicin; hepatocellular carcinoma; transarterial chemoembolization; transarterial chemotherapy infusion; Pharmaceutical Science; Farmaceutisk vetenskap;

    Sammanfattning : There are currently two types of intra-arterial drug-delivery system (DDS) in clinical use in the palliative treatment of primary liver cancer. The chemotherapeutic drug doxorubicin (DOX) can be formulated into a drug-in-lipiodol emulsion (LIPDOX) or a microparticulate drug-eluting bead system (DEBDOX). LÄS MER
