Outcome Measures

Primary Outcomes (4)

  • Pharmacokinetics of tamsulosin OCAS in plasma: AUCtau

    AUCtau (area under the plasma concentration-time curve during the time interval between consecutive dosing)

    Predose, Days 1, and 7-10

  • Pharmacokinetics of solifenacin in plasma: AUCtau

    AUCtau (area under the plasma concentration-time curve during the time interval between consecutive dosing)

    Predose, Days 1, and 7-10

  • Pharmacokinetics of tamsulosin OCAS in plasma: Cmax

    Cmax (maximum concentration)

    Predose, Days 1, and 7-10

  • Pharmacokinetics of solifenacin in plasma: Cmax

    Cmax (maximum concentration)

    Predose, Days 1, and 7-10

Secondary Outcomes (2)

  • Pharmacokinetics of combined doses of tamsulosin OCAS and solifenacin in steady state, and verapamil

    Predose, Days 27-30

  • Safety and tolerability of the interaction between combined doses of tamsulosin OCAS and solifenacin, and verapamil

    Screening to ESV (10 days after the last dosing)
