1. 11. In vivo Pharmacokinetic Interactions of Finasteride and Identification of Novel Metabolites

   Författare :Anna Lundahl; Hans Lennernäs; Dennis A Smith; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; drug-drug interactions; herb-drug interactions; pharmacokinetics; metabolism; CYP3A4; hydroxylation; glucuronidation; UGT enzymes; mass spectrometry; biliary excretion; urinary excretion; finasteride; PHARMACY; FARMACI;

   Sammanfattning : The general aim of this thesis was to improve the understanding of the in vivo pharmacokinetics and, in particular, the metabolism of finasteride, a 5α-reductase inhibitor used in the treatment of enlarged prostate glands and male pattern baldness. CYP3A4 has been identified as the major enzyme involved in the sequential metabolism of finasteride to ω-OH finasteride (M1) and ω-COOH finasteride (M3). LÄS MER

   Sammanfattning : 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. LÄS MER

4. 13. 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.

5. 14. CYP2C19 polymorphisms in drug metabolism and response

   Författare :Ming Chang; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Individuals vary widely in their response to drug treatment. After receiving doses of a drug that are recommended based on a population average, some patients could have an insufficient response, whereas others may experience adverse effects. LÄS MER

7. 15. Pharmacometric Models to Improve Treatment of Tuberculosis

   Författare :Elin M Svensson; Mats O Karlsson; Maria C Kjellsson; Ulrika S H Simonsson; N. L’Ntshotsholé (Shasha) Jumbe; Uppsala universitet; []
   Nyckelord :pharmacokinetics; pharmacodynamics; population approach; nonlinear mixed-effects models; multidrug-resistant tuberculosis; bedaquiline; antiretroviral; drug-drug interactions; time-to-event; albumin; Klinisk farmakologi; Clinical Pharmacology;

   Sammanfattning : Tuberculosis (TB) is the world’s most deadly infectious disease and causes enormous public health problems. The comorbidity with HIV and the rise of multidrug-resistant TB strains impede successful therapy through drug-drug interactions and the lack of efficient second-line treatments. LÄS MER
