Prazosin Effective for Nightmares and Other PTSD Symptoms
Researcher Murray Raskind has conducted a series of controlled studies, all with the same conclusion—the alpha-1 antagonist prazosin, used to treat high blood pressure, works for post-traumatic stress disorder (PTSD), especially in preventing nightmares. In his latest study, 67 soldiers were randomly assigned to either prazosin or placebo for 15 weeks. Doses were slowly titrated (to avoid low blood pressure and dizziness) to a possible maximum dose of 5mg at midmorning and 20mg at bedtime for men and 2mg at midmorning and 10mg at bedtime for women over a period of 6 weeks, based on whether the patients continued to experience nightmares.
Raskind found that prazosin was effective for trauma nightmares, sleep quality, global functioning, total score on a scale of PTSD symptoms, and hyperarousal. Side effects were minimal. Raskin concluded that prazosin “is effective for combat-related PTSD with trauma nightmares in active-duty soldiers, and benefits are clinically meaningful.”
