Outcome Measures

Primary Outcomes (1)

    7 days

  • Area under the plasma concentration (AUC) of MNTX administered as two different oral formulations

    7 days

  • Total body clearance over bioavailability (CL/F) of MNTX administered as two different oral formulations

    7 days

  • Volume of distribution over bioavailability (V/F) of MNTX administered as two different oral formulations
