A Randomized Controlled Trial of Doxazosin for Nightmares Sleep Disturbance and Non-Nightmare Clinical Symptoms in PTSD

Brief description of study

This randomized, double-blind, placebo-controlled trial of doxazosin will assess doxazosin's effectiveness for PTSD nightmares, subjective sleep quality, and non-nightmare PTSD symptoms in adult men and women veterans with full and partial-syndromal PTSD.

Detailed Study Description

This study will involve a randomized, double-blind, placebo-controlled, flexible dose trial of doxazosin (1-16mg) for PTSD nightmares, sleep disturbance and overall PTSD symptoms. The target sample will consist of 60 male and female subjects with chronic PTSD symptoms and prominent nightmares randomly assigned to receive doxazosin (n=30) or placebo (n=30). Participants will be enrolled at the San Francisco VA Medical Center. Following baseline consent procedures, eligibility assessments, and 1-week of baseline assessments including self-report surveys, actigraphy, and at-home EEG (Sleep Profiler), all subjects will initiate doxazosin or equivalently marked placebo at 1mg at bedtime. Subjects will undergo a 4-week titration phase during which doxazosin or placebo may be increased to a maximum dose of 16mg (or equivalently marked placebo) at bedtime based on symptoms and tolerability. After the 4-week titration phase, subjects will continue at stable dose of study medication for a 4-week stable dose phase. Subjects will be asked to complete sleep diaries daily during their participation in the study. In the last week of the stable dose phase, participants will undergo an additional week of at-home sleep monitoring using actigraphy, complete end of treatment surveys, and undergo end-of-treatment clinical assessments and discontinuation of study medication. After discontinuation of study medication, participants will complete three additional days of sleep diaries.
