Background: Increases in the quantity or impact of noradrenergic signaling have been implicated in the pathophysiology of posttraumatic stress disorder (PTSD). This increased signaling may result from increased norepinephrine (NE) release, from altered brain responses to NE, or from a combination of both factors. Here, we tested the hypothesis that Veterans reporting a history of trauma exposure would show an increased association between brain NE and mental health symptoms commonly observed after trauma, as compared to Veterans who did not report a history of trauma exposure, consistent with the possibility of increased brain reactivity to NE after traumatic stress...

A 35-year-old African-American man, who was an active duty service member, presented to the Troop Medical Clinic with a 4-hour history of priapism. He had been taking sertraline 100 mg and prazosin 10 mg nightly for 4 months to treat his posttraumatic stress disorder (PTSD) with no reported adverse effects. These doses were titrated 2 months prior to presentation. The patient reported that he took his usual medication doses before bed and awoke at 3 am with a penile erection. At 7 am, he presented to the clinic because of pain from the continued erection...

Veterans with posttraumatic stress disorder (PTSD) often report suboptimal sleep quality, often described as lack of restfulness for unknown reasons. These experiences are sometimes difficult to objectively quantify in sleep lab assessments. Here, we used a streamlined sleep assessment tool to record in-home 2-channel electroencephalogram (EEG) with concurrent collection of electrodermal activity (EDA) and acceleration. Data from a single forehead channel were transformed into a whole-night spectrogram, and sleep stages were classified using a fully automated algorithm...

BACKGROUND AND OBJECTIVES: Suicide is a significant public health problem among US military Veterans with rates exceeding civilian samples. Alcohol dependence (AD) and posttraumatic stress disorder (PTSD) are both associated with increases in suicidality. Given that risk of suicide is higher among those with both disorders, the study of relevant risk factors among those in this group is important. The current investigation focused on one such factor, hostility, and examined both overt hostility (ie, hostility that is more behavioral in nature and directed outwardly) and covert hostility (ie, hostility that is cognitive in nature and introspective) and their relationships to suicidal ideation...

BACKGROUND: In randomized trials, prazosin, an α1 -adrenoreceptor antagonist, has been effective in alleviating nightmares associated with post-traumatic stress disorder (PTSD) in military veterans. METHODS: We recruited veterans from 13 Department of Veterans Affairs medical centers who had chronic PTSD and reported frequent nightmares. Participants were randomly assigned to receive prazosin or placebo for 26 weeks; the drug or placebo was administered in escalating divided doses over the course of 5 weeks to a daily maximum of 20 mg in men and 12 mg in women...

The α-1 adrenoreceptor antagonist prazosin has shown promise in the treatment of post-traumatic stress disorder (PTSD) symptoms, but its mechanisms are not well understood. Here we administered prazosin or placebo prior to threat conditioning (day 1) and tested subsequent extinction (day 2) and reextinction (day 3) in healthy human participants. Prazosin did not affect threat conditioning but augmented stimulus discrimination during extinction and reextinction, via lower responding to the safe stimulus. These results suggest that prazosin during threat acquisition may have influenced encoding or consolidation of safety processing in particular, subsequently leading to enhanced discrimination between the safe and threatening stimuli...

INTRODUCTION: Youth exposed to trauma have an increased risk for developing posttraumatic stress disorder (PTSD) and associated sleep disturbances and nightmares. The alpha-1 antagonist prazosin reduces sleep disturbances and nightmares in adults with PTSD; however, its use in youth with PTSD has not been systematically evaluated. We retrospectively examined the tolerability and clinical outcomes associated with prazosin treatment in youth with PTSD-related nightmares and dysomnias. METHOD: A retrospective chart review identified youth with PTSD (N = 40) treated with prazosin between 2014 and 2016 in a trauma clinic...

BACKGROUND: Preclinical and clinical research suggest that the α1 receptor antagonist prazosin reduces alcohol consumption. Furthermore, clinical studies indicate a role for prazosin in treating Post-Traumatic Stress Disorder (PTSD) symptoms and a recent trial suggested that pre-treatment blood pressure (BP) predicts therapeutic response for prazosin in PTSD patients. Whether pre-treatment BP may predict response to α1 blockers in alcohol-dependent (AD) patients is unknown. We previously reported a randomized controlled trial (RCT) where doxazosin, an α1 receptor antagonist with a more favorable pharmacokinetic profile than prazosin, reduced drinks per week (DPW) and heavy drinking days (HDD) in AD patients with a high family history density of alcoholism...

BACKGROUND: Clinical guidelines for the management of posttraumatic stress disorder (PTSD) recommend against the use of benzodiazepines. Benzodiazepines and PTSD are both associated with addiction-related risks. The Department of Veterans Affairs (VA) prescribing trends show continued use of benzodiazepines and polysedative use in veterans with PTSD, particularly in rural areas. The authors examine the use of an educational intervention to improve pharmacologic management of veterans with PTSD in rural clinics...

This study tested whether sleep medications prescribed to veterans diagnosed with posttraumatic stress disorder (PTSD) are being targeted to patients who report more severe insomnia or nightmares. Secondary analysis of survey and pharmacy data was conducted in samples of veterans from two periods: from 2006 to 2008 and from 2009 to 2013. Logistic regression tested associations between self-reported insomnia and nightmare severity, and being prescribed trazodone, prazosin, zolpidem, and benzodiazepines, controlling for PTSD severity and other covariates...

The effectiveness of medications for PTSD in general has been well studied, but the effectiveness of medicatio.ns prescribed specifically for post-traumatic stress disorder (PTSD) nightmares is less well known. This retrospective chart review examined the efficacy of various medications used in actual treatment of PTSD nightmares at one Veteran Affairs Hospital. Records at the Salem, VA Veterans Affairs Medical Center (VAMC) were examined from 2009 to 2013 to check for the efficacy of actual treatments used in comparis...

BACKGROUND AND PURPOSE: Nightmares associated with posttraumatic stress disorder (PTSD) are a hallmark symptom among U.S. military veterans who have seen combat. Management of combat-related nightmares can be difficult and current pharmacologic options are limited and tend to have adverse side effects. The aim of this review is to explore recent literature regarding the efficacy of prazosin for the treatment of nightmare disorder in the veteran population. METHODS: Recent literature consisting of three systematic reviews was reviewed, as well as current clinical guidelines published by The Department of Veterans Affairs (VA) and The Department of Defense (DoD) and the American Academy of Sleep Medicine (AASM)...

BACKGROUND: The pharmacological treatment of post-traumatic stress disorder (PTSD) is extremely challenging, as no specific agent has been developed exclusively to treat this disorder. Thus, there are growing concerns among the public, providers and consumers associated with its use as the efficacy of some agents is still in question. AIMS: We applied a dimensional and symptom cluster-based approach to better understand how the heterogeneous phenotypic presentation of PTSD may relate to the initiation of pharmacotherapy for PTSD initial episode...

There is evidence that doxazosin is effective in the treatment of posttraumatic stress disorder (PTSD). Doxazosin is a "me-too" drug of prazosin. Doxazosin has an improved absorption profile and this likely minimizes the risk for unintended adverse hypotensive effects. The availability of doxazosin in the gastrointestinal therapeutic system (GITS) form permits a higher initial daily dose (4 mg/day) while avoiding significant first-dose side effects. The treatment of PTSD with prazosin has several disadvantages due to its short duration of action (6-8 hours), which results in multiple doses being required...
