Altered bioavailability of drugs will potentially affect both drug efficacy as well as safety. In patients subjected to bariatric surgery due to morbid obesity the gastro intestinal tract is considerably reconstructed and a change in drug bioavailability is very likely. Getting further knowledge on important mechanisms responsible for altered bioavailability would help in predicting clinically relevant consequences on different drugs. In the present study we aim to investigate the effect of bariatric surgery on atorvastatin bioavailability. Atorvastatin is subjected to both extensive metabolism and drug transport and will potentially be a good predictor for mechanisms relevant for other drugs as well. In addition will the expression of different enzymes and transporters be measured in the gastrointestinal tract and in the liver to elucidate on mechanism behind the eventual effects.
