Inclusion Criteria
  • Men and women, age 18-60.
  • Participants must have a level of understanding sufficient to agree to all tests and examinations required by the protocol and must sign a written informed consent document. We determine whether they have a sufficient understanding of the study procedures and risks by asking them to explain what's involved in the study and to give examples of study risks and benefits.
  • Participants must fulfill DSM-IV criteria for current PTSD, based on the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) and on the Clinician-Administered PTSD Scale (CAPS).
  • CAPS score must be at least 40 (moderate PTSD severity) at screening.
Exclusion Criteria
  • Current, primary Axis I disorders other than PTSD.
  • History or current bipolar disorder or primary psychotic disorders (e.g. schizophrenia, schizoaffective disorder).
  • Current diagnosis of anorexia nervosa or bulimia nervosa.
  • Women who are pregnant or are breast-feeding.
  • Drug or alcohol abuse or dependence within the preceding 3 months.
  • poorly controlled hypertension (manifest by SBP > 140 and/or DBP > 90); HR < 60 or > 100 at rest at the time of screening and confirmed immediately prior to randomization
  • Evidence of coronary artery disease as evidenced by history, abnormal ECG, typical symptoms
  • History of arrhythmia, cardiac surgery, or family history of sudden death
  • Hepatic dysfunction as defined by AST and ALT > 2x URL, or alkaline phosphatase and bilirubin > 1.5 x URL within X days prior to randomization
  • Chronic renal disease as defined by serum creatinine > 1.9
  • Any other serious or unstable clinically significant abnormal findings of laboratory parameters, physical examination, or ECG as determined by the PI.
  • Any other serious or unstable condition that would put the subjects at undue risk as determined by the PI or additional safety monitor.
  • Serious and imminent suicidal or homicidal risk.
  • Psychotropic medication that will not be tapered off at least 7 days prior to screening; withdrawal symptoms must be absent at the time of screening
  • History of nasal disorders or sinonasal surgery, or significant nasal abnormalities based on nasal exam.
  • Received investigational intervention within 30 days prior to randomization

Arm && Interventions
GroupInterventionDescription
placebo/NPYNeuropeptide YThis arm gets placebo (saline) first then NPY.
NPY/placeboNeuropeptide YThis arm gets NPY first then placebo (saline). The placebo is 0.9% USP-grade saline without NPY.
Primary Outcome Measures
NameTimeMethod
Patient Rated Inventory of Side Effects (PRISE)baseline and within 2 hours of administration of NPY

Clinician-administered and safety measures will take place right before and after the administration to identify and evaluate the tolerability of each possible symptom (from baseline to within 2 hours of NPY administration).

Secondary Outcome Measures
NameTimeMethod
Change in Beck Anxiety Inventory (BAI)at baseline and within 2 hours of administration of NPY

Self-report behavioral measures will take place right before and after the administration to evaluate acute anxiolytic effects of intranasal administration of NPY

State-Trait Anxiety Inventory (STAI)baseline and within 2 hours of administration of NPY

Self-report behavioral measures will take place right before and after the administration to evaluate acute anxiolytic effects of intranasal administration of NPY
