Primary Outcome Measures:
  • AUCinf and Cmax of 5-HMT [ Time Frame: 3 days per period ]

Secondary Outcome Measures:
  • AUClast, Tmax and half-life of 5-HMT as data permit. [ Time Frame: 3 days per period ]
  • Safety will be assessed by subjective symptoms/objective findings including physical examination findings, clinical safety laboratory assessments and adverse event monitoring. [ Time Frame: 3 days per period ]

Enrollment: 28
Study Start Date: May 2009
Study Completion Date: July 2009
Primary Completion Date: July 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Fesoterodine Alone
Reference treatment
Drug: Fesoterodine
Single 8 mg oral dose of fesoterodine
fesoterodine plus fluconazole
Test treatment
Drug: fesoterodine plus fluconazole
On Day 1, fluconazole (200 mg oral dose) will be given 1 hour before and approximately 11 hour following a single 8 mg oral dose of fesoterodine (fesoterodine SD). Fluconazole will also be administered 200 mg BID on the Day 2 (ie, at approximately 24 and 36 hours following the fesoterodine SD treatment given on Day 1)
