  1. 11. In vitro and in silico prediction of drug-drug interactions with transport proteins

    Författare :Gustav Ahlin; Per Artursson; Christel Bergström; Johan Karlsson; Jörg König; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Solute carrier; SLC transporter; OCT1; Organic cation transporter 1; SLC22A1; OATP1B1; SLCO1B1; Organic anion transporting peptide 1B1; Drug transport; Active transport; Genetic polymorphism; Cell lines; Gene expression; Multivariate data analysis; OPLS; Pharmaceutics; Galenisk farmaci; Biopharmacy; Biofarmaci; galenisk farmaci; Pharmaceutics; Biopharmaceutics; biofarmaci;

    Sammanfattning : Drug transport across cells and cell membranes in the human body is crucial for the pharmacological effect of drugs. Active transport governed by transport proteins plays an important role in this process. A vast number of transport proteins with a wide tissue distribution have been identified during the last 15 years. LÄS MER

  2. 12. ATP-Binding Cassette Efflux Transporters and Passive Membrane Permeability in Drug Absorption and Disposition

    Författare :Pär Matsson; Per Artursson; Ulf Norinder; Peter Swaan; Uppsala universitet; []
    Nyckelord :Pharmaceutics; ATP-binding cassette; ABC transporter; P-gp; P-glycoprotein; ABCB1; BCRP; Breast cancer resistance protein; ABCG2; MRP2; Multidrug-resistance associated protein 2; ABCC2; Membrane permeability; Drug transport; Active transport; Passive diffusion; Multivariate data analysis; PLS; OPLS; QSAR; Galenisk farmaci;

    Sammanfattning : Transport into and across the cells of the human body is a prerequisite for the pharmacological action of drugs. Passive membrane permeability and active transport mechanisms are major determinants of the intestinal absorption of drugs, as well as of the distribution to target tissues and the subsequent metabolism and excretion from the body.

  3. 13. 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.

  4. 14. Interindividual Variability of Drug Transport Proteins : Focus on Intestinal Pgp (ABCB1) and BCRP (ABCG2)

    Författare :Gunilla Englund; Per Artursson; Håkan Melhus; Andreas Kindmark; Joseph W Polli; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; membrane transport proteins; ATP-Binding Cassette Transporters; P-glycoprotein; Breast Cancer Resistance Protein; Interindividual variability; Galenisk farmaci; Pharmaceutics; Galenisk farmaci;

    Sammanfattning : The appearance of adverse drug reactions is a common reason for hospitalization in Western countries. Research on underlying biological mechanisms for interindividual variability in drug response aims to better identify patients with exceptional genetic traits, disease conditions or risk of drug-drug interactions and thereby help to prevent adverse drug reactions.

  5. 15. Human liver in vitro models for evaluation of drug metabolism and disposition

    Författare :Malin Darnell; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The administrated dose of a drug is adjusted to give a therapeutic effect in patients without causing side-effects or toxicity. Cytochrome P450 (P450) and UDP-glucuronosyltransferase (UGT) enzymes, uptake and efflux transporters and nuclear receptors regulating these enzymes, expressed in the liver and in other tissues, are all important players in drug metabolism, disposition and elimination.
