Meta-analysis of Pharmacotherapy for PTSD
35 RCTS with 17 positive placebo-controlled trials
Medication response in 59.1%
Placebo response in 38.5%
SSRIs most effective
Medication effects greater for co-morbid depression and
disability
3 maintenance trials suggest long-term medication
Adrenergic-Inhibiting Agents:
Alpha1-Adrenergic Blockers
Prazosin* 7 to 15 mg qhs
Alpha1- post-synaptic adrenoceptor receptor antagonist
Alpha1 receptors widely distributed in the brain, including the amygdala and
hippocampus
Alpha1 receptors modulate sleep and startle responses
Double-blind RCT in 40 veterans, 13.3 +/- 3 mg 1
– Robust improvement in sleep quality and distressing dreams
– Medium to large effect size in each PTSD Sx cluster
– Adverse reactions include: syncope, dizziness, drowsiness,
decreased energy, headache
*Not FDA approved for the treatment of PTSD

Summary: Recommendations for
Immediate Management
Move to safety and reduce terrifying arousal
Psychological First Aid
– Low arousal, facilitate cognitive processing
Education and support
Emphasize need to sustain interpersonal connections
