Arms | Assigned Interventions |
---|---|
A: Experimental
Participants will take propranolol for 14 weeks.
|
Drug: Propanolol
Participants will take a 40-mg dose of propranolol immediately after they experience a traumatic memory associated with strong hyperarousal symptoms. Participants may take up to two doses a day, if the doses are separated by at least 6 hours.
Behavioral: Cognitive therapy workbook
Participants will also receive a cognitive behavioral therapy-based workbook in which they will track symptoms and efforts to use cognitive techniques to relieve symptoms each day.
|
B: Placebo Comparator
Participants will take placebo for 14 weeks.
|
Drug: Placebo
Participants will take a single dose of placebo immediately after they experience a traumatic memory associated with strong hyperarousal symptoms. Participants may take up to two doses a day, if the doses are separated by at least 6 hours.
Behavioral: Cognitive therapy workbook
Participants will also receive a cognitive behavioral therapy-based workbook in which they will track symptoms and efforts to use cognitive techniques to relieve symptoms each day.

Post-traumatic stress disorder (PTSD) is a common and disabling condition, with about 10% of people having experienced PTSD at some point during their lives. The diagnosis of PTSD requires certain criteria: exposure to a severe psychological trauma and the persistent presence of three symptom clusters that include re-experiencing the traumatic event, physiologic hyperarousal, and emotional numbing paired with avoidance of stimuli associated with the event. Stimuli and cues associated with the trauma, such as features of an assailant or accident site, can cause a person to re-experience the traumatic memory and associated feelings of helplessness and fear. When re-experiencing a traumatic memory, people with PTSD usually undergo a heightened stress-related hormonal response that further solidifies new stimulating associations with the traumatic memory. Treatment with propranolol, a blood pressure-lowering drug that reduces stress-related hormonal responses, may be an effective means of preventing the formation of traumatic memories and of improving PTSD symptoms. This study will evaluate the effectiveness of propranolol in reducing symptoms of distress associated with traumatic memories in people with PTSD.
Participation in this study will last 14 weeks. All potential participants will undergo a 4-hour initial visit that will begin with a medical and psychiatric history review, a psychiatric interview, and symptom questionnaires. Participants will then be assigned randomly to take a test dose of either propranolol or placebo. Upon completion of the test dose, participants will begin 14 weeks of treatment with their assigned test dose medication. Participants will be asked to take the study medication each time they have a traumatic memory associated with hyperarousal symptoms, but no more than two times a day. Using a cognitive behavioral therapy based-workbook, participants will track their symptoms daily and when they use cognitive techniques to relieve symptoms.
Participants will attend study visits every 2 weeks for the 14 weeks of treatment. During these visits, participants will describe any side effects experienced, complete interviews and questionnaires about PTSD symptom severity, review with study officials their daily workbook entries, and pick up medication. Study participation will end upon completion of the Week 14 study visit.
