  1. 16. Modelling and Simulation to Improve Antimalarial Therapy

    Författare :Jesmin Permala Lohy Das; Mats Karlsson; Martin Bergstrand; Joel Tarning; Mads Krielgaard; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacometrics; pharmacokinetics; pharmacodynamics; malaria; artemisinin; weekly dosing; resistant; pregnant populations; intermittent preventive therapy; parasite clearance; day 3 positivity; nomogram; Pharmacokinetics and Drug Therapy; Farmakokinetik och läkemedelsterapi; Pharmacokinetics and Drug Therapy; Farmakokinetik och läkemedelsterapi;

    Sammanfattning : The introduction of artemisinin-based combination therapy (ACT) substantially reduced malaria-related mortality and morbidity during the past decade. Despite the widespread use of ACT, there is still a considerable knowledge gap with regards to safety, efficacy and pharmacokinetic properties of these drugs, particularly in vulnerable populations like children and pregnant women.

  3. 17. Methodology for Handling Missing Data in Nonlinear Mixed Effects Modelling

    Författare :Åsa M. Johansson; Mats O. Karlsson; Andrew C. Hooker; Leon Aarons; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 18. Pharmacokinetics and Pharmacodynamics of Oxycodone and Morphine with Emphasis on Blood-Brain Barrier Transport

    Författare :Emma Boström; Margareta Hammarlund-Udenaes; Ulrika Simonsson; Danny D Shen; Uppsala universitet; []
    Nyckelord :Pharmacokinetics Pharmacotherapy; pharmacokinetics; pharamcodynamics; blood-brain barrier; oxycodone; microdialysis; NONMEM; brain distribution; transport; Farmakokinetik Farmakoterapi;

    Sammanfattning : The pharmacokinetics and pharmacodynamics of oxycodone and morphine was investigated and related to the transport across the blood-brain barrier (BBB) in rats. The influence of a P-glycoprotein (P-gp) inhibitor on the plasma pharmacokinetics and pharmacodynamics of oxycodone was evaluated. LÄS MER

  5. 19. Covariate Model Building in Nonlinear Mixed Effects Models

    Författare :Jakob Ribbing; E. Niclas Johnsson; Mats O. Karlsson; Janet Wade; Uppsala universitet; []
    Nyckelord :Pharmacokinetics Pharmacotherapy; Pharmacokinetics; Pharmacodynamics; Modeling; Covariate selection; Stepwise selection; Covariate analysis; Methodology; Model validation; Model evaluation; Type-2 diabetes; Beta-cell function; Meta analysis; Cross-validation; Least absolute shrinkage and selection operator; Pharmacometrics; ED optimization; Farmakokinetik Farmakoterapi;

    Sammanfattning : Population pharmacokinetic-pharmacodynamic (PK-PD) models can be fitted using nonlinear mixed effects modelling (NONMEM). This is an efficient way of learning about drugs and diseases from data collected in clinical trials. LÄS MER
