  Description
Fesoterodine 4 mg, Placebo, Fesoterodine 8 mg, Aplrazolam 1 mg Fesoterodine 4 milligram (mg) tablet administered orally once daily (OD) for 6 days along with placebo matched to a single oral dose of alprazolam 1 mg capsule on Day 6 in the first intervention period; followed by placebo matched to fesoterodine 4 mg or 8 mg tablet orally OD for 6 days along with placebo matched to a single oral dose of alprazolam 1 mg capsule on Day 6 in the second intervention period; then fesoterodine 4 mg tablet administered orally OD for the first 3 days followed by fesoterodine 8 mg tablet orally OD for the next 3 days along with placebo matched to a single oral dose of alprazolam 1 mg capsule on Day 6 in the third intervention period; and placebo matched to fesoterodine 4 mg or 8 mg tablet administered orally OD for 6 days along with a single oral dose of alprazolam 1 mg capsule on Day 6 in the fourth intervention period. A washout period of at least 3 to 6 days was maintained between each treatment period.
