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

    Author : Sibylle Neuhoff; Per Artursson; Anna-Lena Ungell; Patrick Augustijns; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

    Author : Muhammad Waqas Sadiq; Margareta Hammarlund-Udenaes; Sven Björkman; N. Joan Abbott; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 8. Proteomics-informed analysis of drug disposition in the human liver and small intestine

    Author : Christine Wegler; Per Artursson; Pär Matsson; Tommy B Andersson; Manthena Varma; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 9. In vitro and in silico prediction of drug-drug interactions with transport proteins

    Author : Gustav Ahlin; Per Artursson; Christel Bergström; Johan Karlsson; Jörg König; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  7. 10. Topical formulations, design and drug delivery : "A dive into water"

    Author : Abdullah Ali; Marie Lodén; Anan Yagmur; Anders Hall; Malmö universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; water; topical formulations; Pickering emulsion; skin cream; drug delivery; tactile friction; sensory panel; nasal; buccal; mucosa; skin; triglycerides; ethanol; drug transport; cosmetic appeal;

    Abstract : Water is a vital component regulating the properties of topical formulations and their interaction with biological barriers, such as skin and mucosa. Changing the watercontent within the frame of the pharmaceutical triangle will have a huge impact on which type of formulation, such as a cream, ointment, gel, or lotion, is formed, as well as the physical properties of the formulation.
