Summary

This trial will examine whether a new method of reconsolidation blockade, which involves varying the contexts in which the weekly trauma memory retrieval will occur, is effective in treating PTSD among military personnel and Federal police officers.

Who is the study for?
This trial is for military personnel, Federal police officers, or veterans aged 18-65 with occupationally related PTSD as per DSM-5 criteria. Participants must be able to consent and females should use contraception. Exclusions include medical conditions that conflict with propranolol use, certain medication interactions, pregnancy, substance dependence, ongoing litigation related to trauma, strong dissociative tendencies, language barriers (non-English/French speakers), low blood pressure/heart rate, active suicidal thoughts or recent traumatic brain injury.
What is being tested?
The study tests a modified reconsolidation therapy for psychological trauma using propranolol versus placebo. Over six weeks of treatment involving weekly sessions preceded by drug intake an hour before memory reactivation; the mismatch method varies contexts of retrieval. The hypothesis suggests this could improve PTSD symptoms more effectively than standard methods.
What are the potential side effects?
Propranolol may cause side effects like dizziness due to lowered blood pressure, fatigue, trouble sleeping and cold hands or feet. It can also affect heart rhythm and breathing in some individuals.

Experimental Treatment
Active Control
Placebo Group
Group I: Propranolol and standard trauma memory reactivation groupExperimental Treatment1 Intervention

Group II: Propranolol and mismatch trauma memory reactivation groupActive Control1 Intervention
Oral propranolol will be administered 60 minutes prior to a memory reactivation procedure involving variations in the contexts where the trauma memory reactivations occur.
Group III: Placebo and mismatch trauma memory reactivation groupPlacebo Group1 Intervention
Oral placebo will be administered 60 minutes prior to a memory reactivation procedure involving variations in the contexts where the trauma memory reactivations occur.
