    • Neither Gastric Bypass Surgery Nor Diet-Induced Weight-Loss Affect OATP1B1 Activity as Measured by Rosuvastatin Oral Clearance 

      Hovd, Markus Herberg; Robertsen, Ida; Johnson, Line Kristin; Krogstad, Veronica; Wegler, Christine; Kvitne, Kine Eide; Kringen, Marianne K.; Skovlund, Eva; Karlsson, Cecilia; Andersson, Shalini; Artursson, Per; Sandbu, Rune; Hjelmesæth, Jøran Sture; Åsberg, Anders; Jansson-Löfmark, Rasmus; Christensen, Hege (Peer reviewed; Journal article, 2023)
      Introduction Rosuvastatin pharmacokinetics is mainly dependent on the activity of hepatic uptake transporter OATP1B1. In this study, we aimed to investigate and disentangle the effect of Roux-en-Y gastric bypass (RYGB) and ...
    • Short- and long-term effects of body weight, calorie restriction and gastric bypass on CYP1A2, CYP2C19 and CYP2C9 activity 

      Kvitne, Kine Eide; Krogstad, Veronica; Wegler, Christine; Johnson, Line Kristin; Kringen, Marianne K.; Hovd, Markus Herberg; Hertel, Jens Kristoffer; Heijer, Maria; Sandbu, Rune; Skovlund, Eva; Artursson, Per; Karlsson, Cecilia; Andersson, Shalini; Andersson, Tommy B.; Hjelmesæth, Jøran Sture; Åsberg, Anders; Jansson-Löfmark, Rasmus; Christensen, Hege; Robertsen, Ida (Peer reviewed; Journal article, 2022)
      Aim Roux-en-Y gastric bypass (RYGB) may influence drug disposition due to surgery-induced gastrointestinal alterations and/or subsequent weight loss. The objective was to compare short- and long-term effects of RYGB and ...
