  1. 11. Hepatic Disposition of Drugs and the Utility of Mechanistic Modelling and Simulation

    Författare :Erik Sjögren; Hans Lennernäs; Scott Obach; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hepatic disposition; pharmacokinetics; mechanistic modelling; drug-drug interactions; enzyme kinetics; Vmax; Km; CLint; carrier-mediated transport; active transport; modelling; in vitro-in vivo extrapolation; physiologically based pharmacokinetic model; optimal experimental design; experimental optimization; data analysis optimization; PHARMACY; FARMACI; Biopharmacy; Biofarmaci; Biopharmaceutics; Biofarmaci;

    Sammanfattning : The elimination of drugs from the body is in many cases performed by the liver. Much could be gained if an accurate prediction of this process could be made early in the development of new drugs. However, for the elimination to occur, the drug molecule needs first to get inside the liver cell. LÄS MER

  3. 12. Pharmacokinetics, drug metabolism and clinical effects of the antimalarial artemisinin : Time-dependencies and modeling aspects

    Författare :Ulrika Sigrid Helena Svensson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; FARMACI; PHARMACY; FARMACI; Biopharmaceutics; Biofarmaci;

    Sammanfattning : The mechanism behind artemisinin time-dependent bioavailability was investigated using a rat in-situ single-pass jejunal perfusion technique. The consequence for drug combination therapy was studied in healthy volunteers and in patients with Plasmodium falciparum. LÄS MER

  4. 13. Pulmonary Drug Absorption : In vitro and in vivo investigations of drug absorption across the lung barrier and its relation to drug physicochemical properties

    Författare :Ann Tronde; Gerrit Borchard; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; lung; pulmonary; drug delivery; inhalation; drug transport; pharmacokinetics; absorption; bioavailability; drug metabolism; preclinical; rat; in vivo; isolated and perfused lung; Caco-2; nebulization catheter; aerosol; physicochemical; peptide; efflux; FARMACI; PHARMACY; FARMACI; Biopharmaceutics; biofarmaci;

    Sammanfattning : Although, pulmonary drug delivery is a well established means for targeting of drugs to the lungs for the treatment of respiratory diseases as well as for the systemic delivery of volatile anesthetic agents, drug absorption kinetics in the lung have not been subjected to extensive research. The main objective of this thesis was to investigate drug absorption characteristics of the lung barrier, using the isolated and perfused rat lung model and in vivo pharmacokinetic studies in rats.

  5. 14. Pharmacokinetic aspects of the blood-brain barrier transport and equilibration of opioids studied with microdialysis in rats and mice

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

    Sammanfattning : The blood-brain barrier (BBB) transport and equilibration of opioids with different physico-chemical properties and similar structures - codeine, morphine, morphine3-glucuronide (M3G) and morphine-6-glucuronide (M6G) - were investigated in rats and mice using microdialysis. The influences of active efflux pumps, P-glycoprotein (Pgp) and multidrug resistance protein (MRP1), on the BBB transport of morphine and M3G were studied. LÄS MER

  7. 15. Oral delivery of macromolecules formulated with permeation enhancers

    Författare :Staffan Berg; Christel Bergström; Nigel Davies; Andreas Hugerth; David Brayden; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oral peptide delivery; permeation enhancer; sodium caprate; oral drug delivery; intestinal absorption of macromolecules; Biofarmaci; Biopharmaceutics; Galenisk farmaci; Pharmaceutics;

    Sammanfattning : Therapeutic macromolecules including peptides, proteins, and nucleotide-based ones (such as antisense oligonucleotides and RNAs) have great potential as drug candidates. One drawback is that they typically need to be administered parenterally via subcutaneous, intramuscular or intravenous injections. LÄS MER
