  1. 01LabEx vivo tissuePharmacokinetics

    In perfused human placentas, pramlintide had an equilibrium fetal-to-maternal concentration ratio of <=0.006.

    In plain wordsIn lab tests with human placentas, pramlintide concentrations on the fetal side were very low relative to the maternal side.

    Summary
    The ratio of fetal-to-maternal peptide concentrations during equilibrium perfusion were extremely low (pramlintide < or = 0.006, exenatide < or = 0.017).

    Summary · context
    This was examined using ex vivo perfusions of human placentas.
    Summary · context
    Either pramlintide or exenatide was then added to each acceptable cotyledon perfusate on the maternal side.
    Summary · context
    Each peptide was evaluated at an initial concentration near the therapeutic plasma concentration and at approximately 10-50 times that concentration in each of the three cotyledons.
