简要总结

The goal of this study is to evaluate the effect of multiple doses of Desvenlafaxine SR on the pharmacokinetics of Tamoxifen and endoxifen when coadministered to healthy post-menopausal female subjects. This study will also evaluate the safety and tolerability of Desvenlafaxine SR and Tamoxifen when coadministered to healthy post-menopausal female subjects.
