Primary purpose: TREATMENT

Brief summary: Post-traumatic stress disorder (PTSD) can result from having experienced or witnessed a traumatic event. Patients with PTSD symptoms can sometimes experience symptom relief after treatment with antidepressants; however, few patients experience complete symptom relief. There is a need to develop new treatments for PTSD.

This study will evaluate if 12 weeks of using Vortioxetine relieves PTSD symptoms. Vortioxetine has been approved for the treatment of depression; however, Vortioxetine has not been approved by the Food and Drug Administration for the treatment of PTSD.

Detailed description: Patients included in the study will either take the study medication or will take a placebo, a pill without the active medication. This will be determined by chance like a flip of a coin.

Study procedures will include taking study medication and coming to regular in-clinic visits. Depending on the study visit, study tests may include the following: medical evaluations, physical exams, body measurements, vital signs, blood and urine tests, pregnancy tests, genetic testing, heart function monitoring, clinical and psychiatric measures, neuropsychological testing (for example, investigators will test how well you remember words or how fast you perform a certain task), a function test (for example, investigators will test how well you perform certain daily tasks), and a test to measure your startle response. A startle response is an unexpected response by a sudden activity.

3. Current evidence or history of significant unstable medical illness or organic brain impairment, including stroke, Central Nervous System (CNS) tumor, demyelinating disease, cardiac, pulmonary, gastrointestinal, renal or hepatic impairment that would likely interfere with the action, absorption, distribution, metabolism, or excretion of Vortioxetine. History of moderate or more severe Traumatic Brain Injury (TBI) will also be exclusionary.

8. Subject has taken systemic corticosteroids within 2 weeks of the Randomization Visit
9. Treatment with any other psychoactive medication within 2 weeks of Visit 1, including all antidepressants, psychoactive herbal or nutritional treatment (St Johns Wort,S-Adenosyl methionine(SAM-e)), lithium, other mood stabilizers, oral antipsychotics, depot antipsychotics within 12 weeks, beta blockers, thioridazine, pimozide, opiates, anxiolytics, and sedatives (with the exception of zolpidem, eszopiclone, and zaleplon).

10. Pregnancy or lactation\*
11. Subjects who, in the opinion of the investigator, would be noncompliant with the visit schedule or study procedures (e.g. illiteracy, planned vacations, or planned hospitalizations during the study).
12. Any laboratory abnormality that in the investigator's judgment is considered to be clinically significant
13. Patients who are receiving exposure-based psychotherapy that targets PTSD symptoms
14. Current or planned litigation or other actions related to secondary gain regarding the traumatic event
15. Subject has clinical evidence of, or ElectroCardiogram (ECG) results indicating any of the following at either screen or Randomization Visit unless repeat ECG shows that the parameter had returned to within normal range by the Randomization Visit:

    * Q to T interval change (QTc)\> 450 msec for men, or \> 475 msec for women;
    * any cardiac condition or ECG evidence that the investigator feels may pose a potential safety concern.
