Primary Outcome Measures:
  • Daily exposure to bosentan (AUC over 24 hours) [ Time Frame: 24 hours ] [ Designated as safety issue: No ]
    Daily exposure to bosentan, i.e., AUC over a period of 24 h (AUC0-24h), and calculated as a multiple of the exposure over a dosing interval (AUCτ), 3 × AUCτ and 2 × AUCτ for three times and two times daily dosing, respectively.
