  2. 21. 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.

  4. 22. Pharmacometric Models for Individualisation of Warfarin in Adults and Children

    Author : Anna-Karin Hamberg; Mia Wadelius; E Niclas Jonsson; Lena E Friberg; Jeffrey S Barrett; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; warfarin; pharmacokinetics; pharmacodynamics; pharmacometrics; pharmacogenetics; dose individualisation; children; Klinisk farmakologi; Clinical Pharmacology;

    Abstract : Warfarin is one of the most widely used anticoagulants. Therapy is complicated by warfarin’s narrow therapeutic range and pronounced variability in individual dose requirements. Although warfarin therapy is uncommon in children, it is crucial for children with certain congenital or acquired heart diseases. READ MORE

  5. 23. Methodology for Handling Missing Data in Nonlinear Mixed Effects Modelling

    Author : Åsa M. Johansson; Mats O. Karlsson; Andrew C. Hooker; Leon Aarons; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacometrics; population models; censored observations; missing covariates; missing dependent variable; missing data mechanism; missing completely at random MCAR ; missing at random MAR ; missing not at random MNAR ; estimation algorithms; Pharmaceutical Science; Farmaceutisk vetenskap;

    Abstract : To obtain a better understanding of the pharmacokinetic and/or pharmacodynamic characteristics of an investigated treatment, clinical data is often analysed with nonlinear mixed effects modelling. The developed models can be used to design future clinical trials or to guide individualised drug treatment. READ MORE

  6. 24. Optimization of Colistin Dosage in the Treatment of Multiresistant Gram-negative Infections

    Author : Matti Karvanen; Otto Cars; Lena E Friberg; Vincent H Tam; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Colistin; CMS; Pharmacology; Pharmacokinetics; PKPD; Antibiotics; Combination therapy; Pharmacometrics; Dosing regimens; Antibiotic resistance; Infectious Diseases; Infektionssjukdomar;

    Abstract : As multidrug resistance in Gram-negative bacilli increases, the old antibiotic colistin has rapidly gained attention as one of few last line treatment options in the form of colistin methanesulfonate (CMS), which is hydrolyzed to colistin both in vitro and in vivo. There is a dearth of knowledge on fundamental aspects of colistin, including pharmacokinetics and optimal dosing regimens. READ MORE

  7. 25. Pharmacokinetic-Pharmacodynamic modeling and prediction of antibiotic effects

    Author : David D. Khan; Lena Friberg; Hartmut Derendorf; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacometrics; Pharmacokinetics; Pharmacodynamics; PKPD modeling; ciprofloxacin; colistin; E. coli; antibiotics; time-kill experiments; Pharmaceutical Science; Farmaceutisk vetenskap;

    Abstract : Problems of emerging antibiotic resistance are becoming a serious threat worldwide, and at the same time, the interest to develop new antimicrobials has declined. There is consequently a need for efficient methods to develop new treatments that minimize the risk of resistance development and that are effective on infections caused by resistant strains.
