  1. 21. Biopharmaceutical investigations of doxorubicin formulations used in liver cancer treatment : Studies in healthy pigs and liver cancer patients, combined with pharmacokinetic and biopharmaceutical modelling

    Author : Ilse R Dubbelboer; Hans Lennernäs; Erik Sjögren; Hartmut Derendorf; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; drug delivery system; in vivo release; PBPK modelling; hepatocellular carcinoma; doxorubicin; transarterial chemoembolization; drug disposition; Biofarmaci; Biopharmaceutics; Farmaceutisk vetenskap; Pharmaceutical Science;

    Abstract : There are currently two types of drug formulation in clinical use in the locoregional treatment of intermediate hepatocellular carcinoma (HCC). In the emulsion LIPDOX, the cytostatic agent doxorubicin (DOX) is dissolved in the aqueous phase, which is emulsified with the oily contrast agent Lipiodol® (LIP). READ MORE

  2. 22. Models for the Transfer of Drugs from the Nasal Cavity to the Central Nervous System

    Author : Björn Jansson; Erik Björk; Sveinbjörn Gizurarson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biopharmacy; Administration; intranasal; Nasal mucosa; Central nervous system; Olfactory bulb; Rat; Mouse; Swine; Cattle; Diffusion chambers; culture; In vitro; Biological models; Biological transport; Dextrans; Dopamine; Gels; Polysaccharides; Autoradiography; Fluorescence microscopy; Biofarmaci; Biopharmacy; Biofarmaci;

    Abstract : The blood-brain barrier restricts the access of many compounds, including therapeutic agents, to the brain. Several human studies indicate that nasal administration of hydrophilic compounds, such as peptides, can bypass the blood-brain barrier. The aims of this thesis were to develop and refine models for this direct nose-to-brain transfer. READ MORE

  3. 23. In vivo Pharmacokinetics of Two New Thrombin Inhibitor Prodrugs : Emphasis on Intestinal and Hepatobiliary Disposition and the Influence of Interacting Drugs

    Author : Elin Matsson; Hans Lennernäs; Lars Knutson; Ulf Eriksson; Kim Brouwer; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. 24. Drug Dissolution under Physiologically Relevant Conditions In Vitro and In Vivo

    Author : Eva Persson; Hans Lennernäs; Bertil Abrahamsson; Peter Langguth; Uppsala universitet; []
    Keywords : Biopharmacy; solubility; drug dissolution; food effects; poorly soluble drugs; P-gp inhibition; drug absorption; pemeability; bile acids; phospholipids; human intestinal fluid; simulated intestinal fluid; neutral lipids; solid phase extraction; HPLC; Efflux; Biofarmaci;

    Abstract : The general aim of the present project was to increase the understanding of the in vivo dissolution of poorly soluble drugs and thereby improve possibility to predict in vivo solubility from substance properties. Increased understanding of the in vivo limitations of drug solubility could potentially also generate ideas for improved formulation principles for poorly soluble compounds and more relevant in vitro dissolution test methods used in formulation development.

  5. 25. Involvement of Membrane Transport Proteins in Intestinal Absorption and Hepatic Disposition of Drugs Using Fexofenadine as a Model Drug

    Author : Niclas Petri; Hans Lennernäs; Geoffrey Tucker; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biopharmacy; Fexofenadine; OATP; P-glycoprotein; Organic Anion Transporters; ATP-Binding Cassette Transporters; membrane transport proteins; Bioavailability; Biopharmaceutics; Biofarmaci; Biopharmacy; Biofarmaci;

    Abstract : The aims of this thesis were to study the in vivo relevance of membrane transporters for intestinal absorption and the hepatic disposition of drugs in humans and preclinical models. Fexofenadine is a substrate for ABCB1 (P-glycoprotein) and members of the organic anion transporting polypeptide (OATP/SLCO) family. READ MORE
