Arms Assigned Interventions
Experimental: Open label treatment with 3-period crossover design Drug: paroxetine CR
3-period crossover single dosing at the dose levels of 12.5, 25 and 50mg into healthy volunteers

Detailed Description:

This clinical trial is to characterize the pharmacokinetic profile after single oral doses of the proposed final market tablet formulations of paroxetine CR in Japan (the 12.5mg and 25mg tablets), at the dose levels of 12.5, 25 and 50mg in the healthy male Japanese volunteers. Treatment sequence of the 3 dose levels in each subject is randomized.
