  2. 1. Drug absorption in the lungs : studies in the isolated perfused rat lung model combined with physiologically based biopharmaceutics modelling

    Author : Johanna Eriksson; Hans Lennernäs; Erik Sjögren; Helena Thörn; Ben Forbes; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pulmonary drug absorption; physiologically based biopharmaceutics modeling; pulmonary drug delivery; Biofarmaci; Biopharmaceutics;

    Abstract : Pulmonary delivery of drugs is the preferred route of administration for treatment of local lung diseases like asthma and chronic obstructive pulmonary disease. Recently, there has also been increased interest in systemic delivery of drugs via the lungs to avoid problems with low and/or variable gastrointestinal absorption, and as a needle-free alternative for drugs that cannot be ingested.

  4. 2. Computational and Experimental Models for the Prediction of Intestinal Drug Solubility and Absorption

    Author : Christel A. S. Bergström; Per Artursson; Han van de Waterbeemd; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; aqueous drug solubility; melting point; intestinal drug permeability; pH-dependent solubility; multivariate data analysis; molecular descriptors; molecular surface area; in silico modeling; drug absorption; Galenisk farmaci; Pharmaceutics; Galenisk farmaci;

    Abstract : New effective experimental techniques in medicinal chemistry and pharmacology have resulted in a vast increase in the number of pharmacologically interesting compounds. However, the number of new drugs undergoing clinical trial has not augmented at the same pace, which in part has been attributed to poor absorption of the compounds. READ MORE

  5. 3. Application of Mixed-Effect Modeling to Improve Mechanistic Understanding and Predictability of Oral Absorption

    Author : Martin Bergstrand; Mats O Karlsson; Hans Ericsson; Bart Ploeger; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Absorption; magnetic marker monitoring; drug release; IVIVC; pharmacometrics; NONMEM; model diagnostics; pcVPC; pvcVPC; visual predictive check; VPC; BQL; paracetamol; sulfapyridine.; Other pharmacy; Övrig farmaci; Pharmacokinetics and Drug Therapy; Farmakokinetik och läkemedelsterapi;

    Abstract : Several sophisticated techniques to study in vivo GI transit and regional absorption of pharmaceuticals are available and increasingly used. Examples of such methods are Magnetic Marker Monitoring (MMM) and local drug administration with remotely operated capsules. READ MORE

  6. 4. Mechanism-based modeling of biological processes involved in oral absorption

    Author : Benjamin Guiastrennec; Mats O. Karlsson; Martin Bergstrand; Jörg Lippert; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; absorption; bile acids; enterohepatic circulation; food effect; gallbladder; in vitro in vivo correlation; NONMEM; pediatrics; pharmacometrics; tuberculosis; Pharmaceutical Science; Farmaceutisk vetenskap;

    Abstract : For orally administered drugs, the rate and extent of absorption are governed by the physiology of the gastrointestinal tract, the characteristics of the dosage form and the physico-chemical properties of the drug. This thesis primarily aimed to improve the mechanistic understanding and the predictability of processes involved in the absorption of orally administered drugs using a population modeling approach.

    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Piperaquine; malaria; Plasmodium falciparum; antimalarials; ACT; pharmacokinetics; NONMEM; population pharmacokinetics; NCA; bioavailability; enterohepatic circulation; metabolism; metabolites; animal models; bioanalysis; regression models; validation; HPLC; LC-MS MS; H-NMR; FTICR-MS;

    Abstract : Malaria is one of the most abundant parasitic diseases in the world affecting many of the poorest economies. The estimated prevalence is 300 to 700 million clinical episodes each year with up to 3 million deaths. READ MORE
