Brief Summary:
Klarisana is conducting an observational study in San Antonio, Texas to see if there are tangible improvements in the symptoms of post traumatic stress disorder (PTSD) in combat veterans after receiving a series of six low-dose outpatient infusions of ketamine.

Condition or disease Intervention/treatment
Stress Disorders, Post-Traumatic Drug: Ketamine

Detailed Description:

The prolonged conflicts in Iraq and Afghanistan have created a very large population of veterans who suffer from severe post traumatic stress disorder (PTSD). This has, in part, contributed to a rate of suicide that many clinicians and concerned citizens find alarming. In the last two decades, there has been some promising evidence coming to light showing that the medication ketamine can potentially suppress and/or alleviate some of the disturbing symptoms of PTSD such as hypervigilance, anxiety, anger, and recurrent nightmares. If ketamine could be shown to be be a valuable treatment option for PTSD then this could have potentially large positive ramifications for the treatment of PTSD in America's veteran population.

Ketamine has historically been used as a dissociative anesthetic in emergency departments, operating rooms, and in austere military environments. It is a proven medication with a reassuring safety profile. This current study seeks to add to the body of knowledge regarding ketamine therapy by specifically looking at the combat veteran population. Eligible veterans will undergo the standard six-infusion Induction Series of ketamine infusions at Klarisana in San Antonio, Texas. Klarisana is a healthcare center which offers outpatient ketamine infusion therapy for the treatment of severe depression, PTSD, and various chronic pain conditions such as rheumatoid arthritis, fibromyalgia, neuropathy, and migraine headaches. Klarisana serves patients from all over south Texas including Austin, Houston, San Antonio, and Corpus Christi.

Patients who enroll in the current PTSD study will receive a standard battery of survey instruments which Klarisana implements before and after a series of infusions. These instruments will assess each patient's level of depression, degree of PTSD symptoms, as well as their use of alcohol and recreational drugs. The specific instruments are the...

Patient Health Questionnaire (PHQ-9) PTSD Checklist (PCL-5) Drug Abuse Screening Test (DAST-10) Alcohol Use Disorders Identification Test (AUDIT)

The investigator's goal is to formally analyze what changes may occur the participants' symptoms of PTSD and try to better establish the role which ketamine infusion therapy may play in the treatment of PTSD in the combat veteran population.

Drug: Ketamine
Psychological survey instruments administered before and after a series of six low-dose infusions of ketamine.




Primary Outcome Measures :
  1. Participant score on the PTSD Checklist - 5 (PCL-5) after a series of six ketamine infusions. [ Time Frame: 3 weeks ]
    The PCL-5 is a twenty question survey instrument which is used to quantify the level of symptomatology in participants with post-traumatic stress disorder.


Secondary Outcome Measures :
  1. Participant score on the Patient Health Questionnaire - 9 (PHQ-9) after a series of six ketamine infusions. [ Time Frame: 3 weeks ]
    The PHQ-9 is a nine-question survey instrument which is used to quantify the level of depressive symptoms in participants.

  2. Participant score on the Drug Abuse Screening Test (DAST-10) after a series of six ketamine infusions. [ Time Frame: 3 weeks ]
    The DAST-10 is a ten-question self-report survey instrument which is used to assess participants' use of illicit drugs.

  3. Participant score on the Alcohol Use Disorders Identification Test (AUDIT) after a series of six ketamine infusions. [ Time Frame: 3 weeks ]
    The AUDIT is a ten-question self-reporting survey instrument which is used to identify participants' use of and potential dependence on alcohol
