1. 1. Biological and Pharmacological Factor that Influence the Selection of Antibiotic Resistance

   Författare :Ingegerd Gustafsson; Otto Cars; Niels Frimodt-Möller; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microbiology; Human microflora; antibiotic resistance; selection; mutation frequency; biological fitness; pharmacokinetics; pharmacodynamics; β-lactam antibiotics; suboptimal dosing regimen; Mikrobiologi; Microbiology; Mikrobiologi; Klinisk bakteriologi; Clinical Bacteriology;

   Sammanfattning : Antibiotic treatment causes an ecological disturbance on the human microflora. Four commensal bacteria: E. coli, enterococci, a-streptococci and coagulase-negative staphylococci, from patients with extensive, high antibiotic usage were investigated with regard to resistance pattern and mutation frequency.

3. 2. Pharmacodynamic effects of antibiotics : studies on bacterial morphology, initial killing, postantibiotic effect and effecitive regrowth time

   Författare :Håkan Hanberger; Otto Cars; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Pharmacodynamics of antibiotics deals with time course of drug activity and mechanisms of action of drugs on bacteria. In this thesis pharmacodynamic parameters have been studied after brief exposure of gram-positive bacteria to daptomycin, imipenem or vancomycin and after short exposure of gram-negative bacteria to amikacin, ampicillin, aztreonam, cefepime, cefotaxime, ceftazidime, ceftriaxone, cefuroxime, imipenem, mecillinal,11, or piperacillin.

4. 3. 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

5. 4. Study Design and Dose Regimen Evaluation of Antibiotics based on Pharmacokinetic and Pharmacodynamic Modelling

   Författare :Anders Kristoffersson; Lena Friberg; Mats Karlsson; Pernilla Lagerbäck; Otto Cars; Stephan Schmidt; Uppsala universitet; []
   Nyckelord :pharmacometric; optimal design; pharmacokinetics; pharmacodynamics; PKPD; resistance; antibiotics; modeling; time-kill curve; colistin; meropenem; ciprofloxacin; non-linear mixed effects models; bayesian; Farmaceutisk vetenskap; Pharmaceutical Science;

   Sammanfattning : Current excessive use and abuse of antibiotics has resulted in increasing bacterial resistance to common treatment options which is threatening to deprive us of a pillar of modern medicine. In this work methods to optimize the use of existing antibiotics and to help development of new antibiotics were developed and applied. 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
