Summary

This trial tests whether propranolol can help to treat symptoms of PTSD by reducing physiological reactions to trauma reminders.

Who is the study for?
This trial is for adults who have been living with chronic PTSD for at least six months and score high on a trauma impact scale. Participants over 40 must have a normal heart reading from an ECG. They should not start new medications during the study or be taking drugs that affect heart rhythm, and cannot be breastfeeding, have bipolar disorder or psychosis, substance abuse issues, high dissociation levels, or certain medical conditions.
What is being tested?
The study tests if propranolol (a beta-blocker), given in short-acting and long-acting forms along with memory reactivation sessions, can reduce physical responses to trauma memories and ease PTSD symptoms compared to just propranolol without memory reactivation.
What are the potential side effects?
Propranolol may cause low blood pressure, slow heartbeat, fatigue, dizziness upon standing up too fast due to lowered blood pressure (orthostatic hypotension), sleep disturbances, and could potentially worsen symptoms of asthma.

Trial Design

5Treatment groups
Experimental Treatment
Group I: Propranolol + No Memory ReactivationExperimental Treatment1 Intervention
This arm involves administration of propranolol without recalling the traumatic event
Group II: Propranolol + Memory ReactivationExperimental Treatment1 Intervention
This arm involves recalling the traumatic event after administration of propranolol
Group III: Placebo + No Memory ReactivationExperimental Treatment1 Intervention
This arm involves administration of a placebo without recalling the traumatic event
Group IV: Placebo + Memory reactivationExperimental Treatment1 Intervention
This arm involves recalling the traumatic event after administration of a placebo
Group V: Open-label Propranolol + Memory ReactivationExperimental Treatment1 Intervention
All participants terminating the double-blind phase of the study will receive open-label reconsolidation blockade treatment with propranolol combined with recall of the traumatic event for six weeks.
