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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Pharmacokinetic parameters of plasma paroxetine after single doses of paroxetine CR at 12.5mg, 25mg and 50mg in healthy Japanese male volunteers
Time Frame: up to 120 hours after a single dose in all dosing sessions
up to 120 hours after a single dose in all dosing sessions

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Safety and tolerability after single doses of paroxetine CR at 12.5mg, 25mg and 50mg in healthy Japanese male volunteers
Time Frame: up to 120 hours after a single dose in all dosing sessions
up to 120 hours after a single dose in all dosing sessions
