5. Study Description
Brief Summary
To evaluate the effects of multiple oral doses of desvenlafaxine sustained release (DVS SR) and paroxetine on the biotransformation of codeine to morphine in healthy subjects. To assess the safety and tolerability of DVS SR and paroxetine when coadministered with codeine to healthy subjects.
Detailed Description
This is a randomized, open-label, inpatient/outpatient, 3-period crossover study in healthy subjects.The study will consist of 3 treatment periods. In treatment period 1, subjects will be randomly assigned on study day 1. A single 60-mg dose of codeine will be administered to all subjects. In periods 2 and 3, subjects will receive either DVS SR 100 mg/day or paroxetine 20 mg/day until the steady state is reached. At steady state, subjects will receive codeine 60 mg concomitantly with either DVS SR 100 mg or paroxetine 20 mg, depending on the treatment sequence to which they are assigned. DVS SR 100 mg or paroxetine 20 mg administration will continue for an additional 2 days. In treatment period 3, subjects will receive the alternative treatment sequence.
