1. 1. Pharmacometric Models for Individualisation of Warfarin in Adults and Children

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

   Sammanfattning : 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. LÄS MER

3. 2. Pharmacokinetic-Pharmacodynamic Modelling of Anticancer Drugs : Haematological Toxicity and Tumour Response in Hollow Fibres

   Författare :Lena E Friberg; Mats Karlsson; Alan Boddy; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacokinetics Pharmacotherapy; Farmakokinetik Farmakoterapi; PHARMACY; FARMACI; farmakokinetik och läkemedelsterapi; Pharmacokinetics and Drug Therapy;

   Sammanfattning : Established quantitative relationships between dose, plasma concentrations and response [pharmacokinetic-pharmacodynamic (PKPD) models] have a high potential in improving therapeutic indices of anticancer drug therapy and in increasing drug development efficiency. PKPD modelling is a helpful tool for characterising and understanding schedule dependence. LÄS MER

4. 3. Pharmacometrics to improve clinical benefit assessment in oncology

   Författare :Emilie Schindler; Lena E Friberg; Mats O Karlsson; Rik de Greef; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nonlinear mixed effect models; NONMEM; pharmacokinetics; pharmacodynamics; VEGF; SLD; targeted therapies; IRT; FDG-PET; SUVmax; Farmaceutisk vetenskap; Pharmaceutical Science;

   Sammanfattning : The high attrition rate in oncology drug development calls for new approaches that would increase the understanding of drugs’ efficacy and safety profiles. This thesis focuses on the development of pharmacometric models to characterize and quantify the relationships between drug exposure, circulating and imaging biomarkers, adverse effects, overall survival (OS), and patient-reported outcomes (PROs).

5. 4. Optimization of Colistin Dosage in the Treatment of Multiresistant Gram-negative Infections

   Författare :Matti Karvanen; Otto Cars; Lena E Friberg; Vincent H Tam; Uppsala universitet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

7. 5. Pharmacometric Models for Antibacterial Agents to Improve Dosing Strategies

   Författare :Elisabet I Nielsen; Lena E Friberg; Otto Cars; Mats O Karlsson; Marie Sandström; Alan Forrest; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacometrics; pharmacokinetics; pharmacodynamics; modeling; NONMEM; antibiotics; in vitro; time-kill curve; PK PD indices; gentamicin; aminoglycosides; newborn infants; premature infants; cystatin C; Biopharmacy; Biofarmaci; Pharmacokinetics and Drug Therapy; Farmakokinetik och läkemedelsterapi;

   Sammanfattning : Antibiotics are among the most commonly prescribed drugs. Although the majority of these drugs were developed several decades ago, optimal dosage (dose, dosing interval and treatment duration) have still not been well defined. LÄS MER
