  • Patent number: 11519834
    Abstract: An in vitro intestinal drug disposition device (1) comprises a donor chamber (2) for a donor solution and having a bottom end (18) and a top end (19). The device (1) also comprises a receiver chamber (3) for an absorption solution and an absorption membrane (4) arranged in between and separating the chambers (2, 3). A first side (5) of the absorption membrane (4) is to be in contact with the donor solution and a second side (6) of the absorption membrane (4) is to be in contact with the absorption solution.
