Objective: The authors assessed the efficacy of trauma memory reactivation performed under the influence of propranolol, a noradrenergic beta-receptor blocker, as a putative reconsolidation blocker, in reducing symptoms of posttraumatic stress disorder (PTSD).
Method: This was a 6-week, double-blind, placebo-controlled, randomized clinical trial in 60 adults diagnosed with long-standing PTSD. Propranolol or placebo was administered 90 minutes before a brief memory reactivation session, once a week for 6 consecutive weeks. The hypothesis predicted a significant treatment effect of trauma reactivation with propranolol compared with trauma reactivation with placebo in reducing PTSD symptoms on both the Clinician-Administered PTSD Scale (CAPS) and the patient-rated PTSD Checklist–Specific (PCL-S) in an intention-to-treat analysis.
