Primary Completion Date: June 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Tolterodine Drug: Tolterodine

Detailed Description:

After a single oral administration of 2 mg tolterodine in 31 healthy subjects (6 with the heterozygous mutation of HNF-4A G60D vs 25 subjects with wild type of that whose CYP2D6 genotype and gender were matched with variant group), blood were collected for 24hrs. Assay of tolterodine and the metabolite, 5-hyroxymethyl tolterodine was conducted using LC/MS/MS.
