This is a multiple-dose study to assess the safety and pharmacology of ABT-436 in physically healthy subjects with mild to moderate depressive symptoms who are not taking any antidepressant medication. Efficacy for treatment of depressive symptoms is not a goal of this study. Fifty subjects will receive study drug for seven days. Thirty subjects will receive ABT-436 and twenty subjects will receive placebo.
