Primary Outcome Measures :
  1. Montgomery-Asberg Depression Rating Scale (MADRS) [ Time Frame: 24 hours ]

    Number of patients meeting response criteria of >=50% decrease in MADRS score from baseline , ie, difference in depressive symptoms using MADRS instrument, 24 hours following drug administration

    10-item instrument used for the evaluation of depressive symptoms in adults and for the assessment of any changes to those symptoms. Each of the 10 items is rated on a scale of 0 to 6, with differing descriptors for each item. These individual item scores are added together to form a total score, which can range between 0 and 60 points.

Secondary Outcome Measures :
  1. Systematic Assessment for Treatment Emergent Effects (SAFTEE) [ Time Frame: 2 weeks ]
    This is a self-report measure for systematically assessing 48 possible adverse events. It documents their severity, relationship to study drug, and the action taken.
