  1. 1. Intracellular unbound drug concentrations : Methodology and application for understanding cellular drug exposure

    Författare :André Mateus; Per Artursson; Pär Matsson; José A. G. Morais; Jeff Krise; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intracellular unbound drug concentrations; free drug; drug binding; drug transport; drug accumulation; cellular drug response; drug target engagement; Pharmaceutical Science; Farmaceutisk vetenskap;

    Sammanfattning : Most known drug targets and metabolizing enzymes are located inside cells. Interactions with these proteins are determined by intracellular unbound drug concentrations. Assessing intracellular drug exposure is technically challenging, but essential for predicting pharmacokinetic, pharmacological, and toxicological profiles of new drugs. LÄS MER

  2. 2. In Vivo Active Drug Uptake and Efflux at the Blood-Brain Barrier : With Focus on Drug Transport Interactions

    Författare :Muhammad Waqas Sadiq; Margareta Hammarlund-Udenaes; Sven Björkman; N. Joan Abbott; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood-brain barrier; Active uptake transport; Microdialysis; P-glycoprotein; Drug interactions; Species differences; Pharmacokinetics; Pharmacodynamics; NONMEM; Pharmaceutical Science; Farmaceutisk vetenskap;

    Sammanfattning : The blood-brain barrier (BBB) controls the movement of substances into and out of the brain. The tight junctions between endothelial cells and energy dependent transporters in the BBB influence rate and extent of drug distribution to the brain. LÄS MER

  3. 3. 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

  4. 4. Drug interaction surveillance using individual case safety reports

    Författare :Johanna Strandell; Staffan Hägg; Niklas Norén; Andrew Bate; Robin E. Ferner; Linköpings universitet; []
    Nyckelord :Adverse drug reactions; adverse drug interaction surveillance; drug interactions; individual case safety reports; postmarketing pharmacovigilance; signal detection; MEDICINE; MEDICIN;

    Sammanfattning : Background: Drug interactions resulting in adverse drug reactions (ADRs) represent a major health problem both for individuals and society in general. Post-marketing pharmacovigilance reporting databases with compiled individual case safety reports (ICSRs) have been shown to be particularly useful in the detection of novel drug - ADR combinations, though these reports have not been fully used to detect adverse drug interactions.

  5. 5. Refined in vitro Models for Prediction of Intestinal Drug Transport : Role of pH and Extracellular Additives in the Caco-2 Cell Model

    Författare :Sibylle Neuhoff; Per Artursson; Anna-Lena Ungell; Patrick Augustijns; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; Caco-2 cells; membrane permeability; drug permeation; drug efflux ratios; drug uptake ratios; Cremophor EL; bovine serum albumin; pH-dependent permeability; drug transport; FARMACI; PHARMACY; FARMACI;

    Sammanfattning : Drug transport across the intestinal epithelium is roughly predicted from permeability values obtained from Caco-2 cell monolayers. This thesis examines the important role of pH and extracellular additives for increasing the reliability and predictivity of the in vitro screening system, Caco-2. LÄS MER
