Abstract
BACKGROUND Researchers often conduct small studies on testing a drug's efficacy in off-label indications. If positive results from these exploratory studies are not followed up by larger, randomized, double-blinded trials, physicians cannot be sure of a drug's clinical value. This may lead to off-label prescriptions of ineffective treatments. We aim to describe the way clinical studies fostered off-label prescription of the antipsychotic drug quetiapine (Seroquel). METHODS In this systematic meta-epidemiological analysis, we searched EMBASE, MEDLINE, Cochrane CENTRAL and PsycINFO databases and included clinical studies testing quetiapine for unapproved indications between May 1995 and May 2022. We then assessed the frequency with which publications providing low-level evidence suggesting efficacy of quetiapine for off-label indications was not followed up by large, randomized and double-blinded trials within 5 years. RESULTS In total, 176 published studies were identified that reported potential efficacy of quetiapine in at least 26 indications. Between 2000 and 2007, publication of exploratory studies suggesting promise for off-label indications rapidly outpaced publication of confirmatory trials. In the 24 indications with a minimum of 5 years of follow-up from the first positive exploratory study, 19 (79%) were not followed up with large confirmatory trials within 5 years. At least nine clinical practice guidelines recommend the use of quetiapine for seven off-label indications in which published confirmatory evidence is lacking. CONCLUSION Many small, post-approval studies suggested the promise of quetiapine for numerous off-label indications. These findings generally went unconfirmed in large, blinded, randomized trials years after first being published. The imbalance of exploratory and confirmatory studies likely encourages ineffective off-label treatment.

Abstract
Posttraumatic stress disorder (PTSD) is a neuropsychiatric disease closely related to life-threatening events and psychological stress. Re-experiencing, hyperarousal, avoidance, and numbness are the hallmark symptoms of PTSD, but their underlying neurological processes have not been clearly elucidated. Therefore, the identification and development of drugs for PTSD that targets brain neuronal activities have stalled. Considering that the persistent fear memory induced by traumatic stimulation causes high alertness, high arousal, and cognitive impairment of PTSD symptoms. While the midbrain dopamine system can affect physiological processes such as aversive fear memory learning, consolidation, persistence, and extinction, by altering the functions of the dopaminergic neurons, our viewpoint is that the dopamine system plays a considerable role in the PTSD occurrence and acts as a potential therapeutic target of the disorder. This paper reviews recent findings on the structural and functional connections between ventral tegmental area neurons and the core synaptic circuits involved in PTSD, gene polymorphisms related to the dopamine system that confer susceptibility to clinical PTSD. Moreover, the progress of research on medications that target the dopamine system as PTSD therapies is also discussed. Our goal is to offer some hints for early detection and assist in identifying novel, efficient approaches for treating PTSD.

Abstract
BACKGROUND Post-traumatic stress disorder (PTSD) is a mental disorder that can emerge after an individual experiences a traumatic event such as physical abuse, sexual/relationship violence, combat exposure, witnessing death, or serious injury. This study aimed to identify the most suitable drugs for the management of PTSD based on a network meta-analysis (NMA). METHODS Six databases (Ovid Medline, EMBase, CENTRAL, PsycINFO, Ovid Health and Psychosocial Instruments, and Web of Science) were searched from inception to September 6, 2022. RESULTS Thirty articles with a total of 5170 participants were included. Compared with placebo, active drugs including olanzapine (SMD = -0.66, 95% CI: -1.19 to -0.13), risperidone (SMD = -0.23, 95% CI: -0.42 to -0.03), quetiapine (SMD = -0.49, 95% CI: -0.93 to -0.04), venlafaxine (SMD = -0.29, 95% CI: -0.42 to -0.16), sertraline (SMD = -0.23, 95% CI: -0.34 to -0.11), paroxetine (SMD = -0.48, 95% CI: -0.60 to -0.36) and fluoxetine (SMD = -0.27, 95% CI: -0.42 to -0.12), significantly reduced the total clinician-administered PTSD scale score. CONCLUSION The results of this study support the use of paroxetine, venlafaxine, and quetiapine as first-line treatment for PTSD. In addition, quetiapine is recommended for patients with PTSD affected by symptoms of hyperarousal and re-experience disorder. Clinicians should prescribe medications based on the severity of PTSD symptoms and other conditions to develop the best treatment strategy for this patient population.

Abstract
Paroxetine and Sertraline are the only medications approved in posttraumatic stress disorder (PTSD). However, about 60% of traumatized patients fail to show an adequate clinical response. Second generation antipsychotics are recommended as second-line monotherapy or third-line augmentation strategies and quetiapine appears as one of the most used and promising agents. Up to date, no reviews assessed the efficacy of quetiapine in the treatment of PTSD. We aimed to assess the effectiveness and general safety of quetiapine on PTSD. A systematic review was conducted following Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) and Cochrane guidelines, selecting studies that evaluated the efficacy of quetiapine on global or specific PTSD symptomatology. Ten studies (n = 894) were considered eligible for qualitative synthesis: one case report, one case series, one prospective cohort study, 3 open-label trials, 3 retrospective studies, one randomized controlled trial. Quetiapine was effective on global PTSD symptomatology assessed in 6 studies as well as on re-experiencing (4/4 studies), avoidance (4/3 studies) and hyperarousal (4/4 studies), flashbacks (2/2 studies), depressive (4/4 studies), anxiety (1/1 studies), psychotic (3/3 studies), insomnia (4/5 studies), nightmares (3/3 studies) specific symptoms and PTSD domains. Sedation was among the most frequently observed adverse effects and the main cause of drug discontinuation. Preliminary findings support the efficacy of quetiapine in ameliorating symptoms relative to PTSD and its overall safety. However, quetiapine use in PTSD cannot be recommended yet as studies mainly rely on open-label, retrospective studies or case series.

Abstract
Post-traumatic stress disorder (PTSD) is a disabling psychiatric condition with a critical familiar, personal, and social impact. Patients diagnosed with PTSD show various symptoms, including anxiety, depression, psychotic episodes, and sleep disturbances, complicating their therapeutic management. Only sertraline and paroxetine, two selective serotonin reuptake inhibitors, are approved by different international agencies to treat PTSD. In addition, these drugs are generally combined with psychotherapy to achieve positive results. However, these pharmacological strategies present limited efficacy. Nearly half of the PTSD patients do not experience remission of symptoms, possibly due to the high prevalence of psychiatric comorbidities. Therefore, in clinical practice, other off-label medications are common, even though the effectiveness of these drugs needs to be further investigated. In this line, antipsychotics, antiepileptics, adrenergic blockers, benzodiazepines, and other emerging pharmacological agents have aroused interest as potential therapeutic tools to improve some specific symptoms of PTSD. Thus, this review is focused on the most widely used drugs for the pharmacological treatment of PTSD with a translational approach, including clinical and preclinical studies, to emphasize the need to develop safer and more effective medications.

Abstract
BACKGROUND People with a history of complex traumatic events typically experience trauma and stressor disorders and additional mental comorbidities. It is not known if existing evidence-based treatments are effective and acceptable for this group of people. OBJECTIVE To identify candidate psychological and non-pharmacological treatments for future research. DESIGN Mixed-methods systematic review. PARTICIPANTS Adults aged ≥ 18 years with a history of complex traumatic events. INTERVENTIONS Psychological interventions versus control or active control; pharmacological interventions versus placebo. MAIN OUTCOME MEASURES Post-traumatic stress disorder symptoms, common mental health problems and attrition. DATA SOURCES Cumulative Index to Nursing and Allied Health Literature (CINAHL) (1937 onwards); Cochrane Central Register of Controlled Trials (CENTRAL) (from inception); EMBASE (1974 to 2017 week 16); International Pharmaceutical Abstracts (1970 onwards); MEDLINE and MEDLINE Epub Ahead of Print and In-Process & Other Non-Indexed Citations (1946 to present); Published International Literature on Traumatic Stress (PILOTS) (1987 onwards); PsycINFO (1806 to April week 2 2017); and Science Citation Index (1900 onwards). Searches were conducted between April and August 2017. REVIEW METHODS Eligible studies were singly screened and disagreements were resolved at consensus meetings. The risk of bias was assessed using the Cochrane risk-of-bias tool and a bespoke version of a quality appraisal checklist used by the National Institute for Health and Care Excellence. A meta-analysis was conducted across all populations for each intervention category and for population subgroups. Moderators of effectiveness were assessed using metaregression and a component network meta-analysis. A qualitative synthesis was undertaken to summarise the acceptability of interventions with the relevance of findings assessed by the GRADE-CERQual checklist. RESULTS One hundred and four randomised controlled trials and nine non-randomised controlled trials were included. For the qualitative acceptability review, 4324 records were identified and nine studies were included. The population subgroups were veterans, childhood sexual abuse victims, war affected, refugees and domestic violence victims. Psychological interventions were superior to the control post treatment for reducing post-traumatic stress disorder symptoms (standardised mean difference -0.90, 95% confidence interval -1.14 to -0.66; number of trials = 39) and also for associated symptoms of depression, but not anxiety. Trauma-focused therapies were the most effective interventions across all populations for post-traumatic stress disorder and depression. Multicomponent and trauma-focused interventions were effective for negative self-concept. Phase-based approaches were also superior to the control for post-traumatic stress disorder and depression and showed the most benefit for managing emotional dysregulation and interpersonal problems. Only antipsychotic medication was effective for reducing post-traumatic stress disorder symptoms; medications were not effective for mental comorbidities. Eight qualitative studies were included. Interventions were more acceptable if service users could identify benefits and if they were delivered in ways that accommodated their personal and social needs. LIMITATIONS Assessments about long-term effectiveness of interventions were not possible. Studies that included outcomes related to comorbid psychiatric states, such as borderline personality disorder, and populations from prisons and humanitarian crises were under-represented. CONCLUSIONS Evidence-based psychological interventions are effective and acceptable post treatment for reducing post-traumatic stress disorder symptoms and depression and anxiety in people with complex trauma. These interventions were less effective in veterans and had less of an impact on symptoms associated with complex post-traumatic stress disorder. FUTURE WORK Definitive trials of phase-based versus non-phase-based interventions with long-term follow-up for post-traumatic stress disorder and associated mental comorbidities. STUDY REGISTRATION This study is registered as PROSPERO CRD42017055523.

Abstract
OBJECTIVE The aim of this paper was to cross-sectionally examine the association between physical health indicators and PTSD symptomatology. METHOD A cross-sectional study was conducted among inpatients of a service related trauma-focused ward. Physical and mental health indicators including sleep quality, fitness, physical activity, body mass index and PTSD symptomatology were assessed. RESULTS Among 60 inpatients, significant associations were found between sedentary time (r = 0.42; p < .001) and sleep quality (r = 0.40; p < .001) with PTSD symptomatology. The vast majority of inpatients (n = 56; 93%) were found to be either overweight or obese according to body mass index. CONCLUSION Inpatients of a PTSD treatment facility had extremely high rates of obesity, physical inactivity, poor cardiorespiratory fitness and poor sleep quality. Sedentary behaviour is a modifiable risk factor associated with symptoms and physical health.

Abstract
BACKGROUND Posttraumatic stress disorder (PTSD) is often a chronic, disabling illness for which antidepressant medications (ie, SSRI) are considered the primary psychopharmacological treatment. However, many patients remain refractory to antidepressants alone or in combination with psychotherapy. Safe and effective treatments for individuals with refractory PTSD are needed. This study aimed to examine ziprasidone augmentation of SSRI treatment of PTSD. METHODS This was a 2-phase study. In phase 1, subjects were treated with paroxetine or sertraline for 8 weeks. Individuals refractory to the SSRI treatment then entered into phase II of the study and were randomized, in a double-blind fashion, to 8 weeks of treatment with either ziprasidone or placebo. The primary outcome measure was change in Clinician Administered PTSD Scale total scores with the intent-to-treat sample. Secondary outcome measures included Positive and Negative Syndrome Scale scores, measures of depression and anxiety, and safety measures. RESULTS No significant differences were observed on the Clinician Administered PTSD Scale, Positive and Negative Syndrome Scale, or other outcome measures between ziprasidone and placebo groups. No significant differences were observed for safety measures including metabolic profiles, extrapyramidal symptoms/movement disorder rating scales, nor study dropout. CONCLUSIONS Although no significant differences were noted in efficacy or safety measures between ziprasidone and placebo in this pilot study, the small sample size prevents definitive conclusions.

Abstract
Trauma exposure leads to various psychiatric disorders including depression, anxiety, bipolar disorders, personality disorders, psychotic disorders, and trauma related disorders, especially posttraumatic stress disorder (PTSD). There are some overlapping symptoms of both PTSD and psychosis that make diagnosis challenging. Despite this overlap, the evidence of PTSD with comorbid psychosis as a distinct entity lies in the research showing biologic, genetic and treatment management differences between psychotic PTSD, non-psychotic PTSD, psychotic disorders and healthy controls. There is emerging evidence that PTSD with secondary psychotic features (PTSD-SP) might be a discrete entity of PTSD with known risk factors that increase its prevalence. This review has presented evidence for individuals with PTSD-SP being distinct in genetics and neurobiological factors. Individuals with PTSD and comorbid psychosis can benefit from evidence based psychotherapy (EBT). There is not enough evidence to recommend second generation antipsychotics (SGA) for PTSD-SP given that risperidone and quetiapine are the only SGAs studied in randomized controlled trials. Hence, developing an operational diagnostic criteria and treatment framework for clinical and research use is critical.

Abstract
SummaryAs many as 10% of the population experience post-traumatic stress disorder (PTSD) at some time in their lives. It often runs a severe, chronic and treatment-resistant course. This article reviews the evidence base for typically recommended treatments such as cognitive-behavioural therapy (CBT), eye movement desensitisation and reprocessing and selective serotonin reuptake inhibitors (SSRIs). It tabulates the major randomised controlled trials of SSRIs and trauma-focused CBT and reviews research on novel treatments such as ketamine, MDMA, quetiapine, propranolol and prazosin.

Abstract
Post-traumatic stress disorder (PTSD) is a serious psychiatric consequence of trauma that occurs in a proportion of individuals exposed to life-threatening events. Trauma-focused psychotherapy is often recommended as first choice for those who do not recover spontaneously. But many individuals require medications. In the US, only paroxetine (PRX) and sertraline (SRT) are FDA approved for PTSD. But response and remission rates with these medications are low, so numerous other pharmacologic interventions have been tried. To date, there has not been a systematic review of the data on what are the best next-step pharmacologic strategies for individuals who fail standard treatments. To that end, we review 168 published trials of medications other than PRX or SRT and provide a detailed analysis of the 88/168 studies that describe alternative pharmacologic interventions in patients refractory to other treatment. We also review clinical factors relevant to treatment-refractory PTSD; the neurobiology of extinction, as well as evidence-based psychotherapy and neuromodulation strategies for this condition.

Abstract
PURPOSE Results of a study of psychotropic prescribing patterns in a Veterans Affairs (VA) population with posttraumatic stress disorder (PTSD) are presented. METHODS VA prescription records were reviewed to identify veterans with PTSD at a large VA healthcare center and evaluate their medication regimens for conformance with a VA practice guideline that calls for the use of selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) as first-line therapies for PTSD; the VA guideline does not recommend second-generation antipsychotics (SGAs) and benzodiazepines for PTSD symptom control. The primary objective was to determine if veterans with PTSD who were receiving an SGA had first received SSRI or SNRI therapy in accordance with VA recommendations. RESULTS Among 308 veterans who met the inclusion criteria, the average number of SSRI or SNRI agents prescribed prior to initiation of SGA therapy was 0.88. Only 19.8% of patients (n = 61) had been prescribed 2 SSRI or SNRI agents, with 48.4% of patients (n = 149) having received 1 agent. All evaluated courses of SSRI and SNRI therapy prior to SGA initiation were of sufficient duration (range, 5-30 months), and mean adherence rates were >80%. Current or past benzodiazepine use was documented in about 55% of patients (n = 170). CONCLUSION SSRIs and SNRIs were under-utilized for the treatment of PTSD at the study site in patients receiving an SGA. The current use of benzodiazepines in these patients was lower than a reported national average for VA patients.

Abstract
Many individuals with post-traumatic stress disorder (PTSD) experience persistent symptoms despite pharmacological treatment with antidepressants. Several open-label monotherapy and adjunctive studies have suggested that aripiprazole (a second-generation antipsychotic) may have clinical utility in PTSD. However, there have been no randomized placebo-controlled trials of aripiprazole use for PTSD. We thus conducted a pilot randomized controlled trial of adjunctive aripiprazole versus placebo among Veterans with chronic PTSD serving in the US military since 11 September 2001 to assess the feasibility, safety, tolerability, and therapeutic potential of aripiprazole. Sixteen Veterans were randomized, and 14 completed at least 4 weeks of the study; 12 completed the entire 8-week trial. Outcome measures included the Clinician-Administered PTSD Scale (CAPS), PTSD Checklist, Beck Depression Inventory, Second Edition, and Positive and Negative Syndrome Scale scores. Aripiprazole was well-tolerated in this cohort, and improvements in CAPS, PTSD Checklist, Beck Depression Inventory, Second Edition, and Positive and Negative Syndrome Scale scores were as hypothesized. Although CAPS change scores did not reach statistical significance, aripiprazole outperformed placebo by 9 points on the CAPS in the last observation carried forward analysis compared with the placebo group (n = 7 per group), and by 20 points in the group randomized to aripiprazole that completed the entire study (n = 5) compared with the placebo group (n = 7). Results suggest promise for aripiprazole as an adjunctive strategy for the treatment of PTSD.

Role of quetiapine beyond its clinical efficacy in bipolar disorder: From neuroprotection to the treatment of psychiatric disorders (Review). Exp Ther Med 2015; 9:643-652.

Abstract
The aim of the present review was to discuss the following aspects of treatment with quetiapine in psychiatric disorders: i) Neurocognition and functional recovery in bipolar disorder (BD); ii) neuroprotective profile in different models; and iii) potential off-label indications. A PubMed search was conducted of articles published in English between 2000 and 2012 on quetiapine, cross-referenced with the terms ‘anxiety’, ‘attention deficit disorder’, ‘borderline personality disorder’, ‘dementia’, ‘insomnia’, ‘major depressive disorder’ (MDD), ‘obsessive-compulsive disorder’, ‘post-traumatic stress disorder’, ‘remission’, ‘cognition’, ‘neurobiology’, ‘neuroprotection’, ‘efficacy’ and ‘effectiveness’. Articles were selected from meta-analyses, randomized clinical trials and open trials, and the results were summarized. Quetiapine, when studied in off-label conditions, has shown efficacy as a monotherapy in MDD and general anxiety disorder. Quetiapine also appears to exhibit a small beneficial effect in dementia. The review of other conditions was affected by methodological limitations that precluded any definitive conclusions on the efficacy or safety of quetiapine. Overall, the present review shows evidence supporting a potential role for quetiapine in improving cognition, functional recovery and negative symptoms in a cost-effective manner in BD. These benefits of quetiapine are potentially associated with its well-described neuroprotective effects; however, further studies are clearly warranted.

Abstract
Evidence-based treatment approaches for generalized anxiety disorder (GAD) comprise psychotherapy, pharmacotherapy, or a combination of the two. First-line pharmacotherapy agents include selective serotonin reuptake inhibitors, selective serotonin-norepinephrine reuptake inhibitors, and, in certain European guidelines, pregabalin, which gained European Commission approval. Although short- and long-term efficacy have been established for these agents in controlled trials, response rates of 60-70 % are insufficient, remission rates are relatively modest, and relapse rates considerable. Moreover, questions increasingly arise regarding tolerability and side-effect profiles. As an alternative, antipsychotics have long been of interest for the treatment of anxiety disorders, but investigation had been tempered by their potential for irreversible side effects. With the improved side-effect profiles of atypical antipsychotics, these agents are increasingly being investigated across Axis I disorders. Atypical antipsychotics such as quetiapine, aripiprazole, olanzapine, and risperidone have been shown to be helpful in addressing a range of anxiety and depressive symptoms in individuals with schizophrenia and schizoaffective disorders, and have since been used in the treatment of a range of mood and anxiety disorders. In this article, we review the efficacy and tolerability of atypical antipsychotics as adjunctive therapy and/or monotherapy for individuals with GAD, a currently off-label indication. The most evidence has accumulated for quetiapine. Findings suggest that approximately 50 % of participants tolerate the side effects, most commonly sedation and fatigue. Among this subset, those who continue treatment demonstrate significant reductions in anxiety when used as adjunctive therapy or monotherapy. The appropriateness of the use of antipsychotics in the treatment of GAD is discussed.

Abstract
Post-traumatic stress disorder (PTSD) is a serious mental illness of considerable importance from a public health perspective. Management of PTSD may involve the use of various treatment modalities, involving both nondrug treatments and pharmacotherapy. Nondrug treatment is regarded as the first-line option for PTSD and should be routinely incorporated into management plans for patients with PTSD. However, some patients do not achieve a sufficient response to nondrug therapy or are left with disabling residual symptoms in one or more areas. Antidepressants are currently the preferred medication for PTSD, with the most substantial evidence available to support the use of the selective serotonin reuptake inhibitors. Many patients with PTSD have symptoms that are resistant to initial drug treatment, meaning that it is often necessary to explore additional pharmacotherapy options to achieve optimal symptom control: antipsychotics, anti-adrenergic drugs, anxiolytics and anticonvulsants have all been advocated as treatments for PTSD. In addition to the management of core PTSD symptoms, it is also necessary for clinicians to address important associated comorbidities, most notably, substance-use disorders and mood disturbances. Interpretation of research studies of the efficacy and safety of PTSD pharmacotherapy is often difficult owing to methodological limitations and factors such as inclusion bias. Further research in fundamental neurosciences and pharmacogenomics may help to elucidate optimal pharmacotherapy options for PTSD in the future.

Abstract
Post-traumatic stress disorder is a difficult to treat, yet common disorder, which is associated with significant morbidity, mortality and societal burden. Comprehensive management of post-traumatic stress disorder must include both psychotherapeutic and pharmacologic components. The current evidence-based pharmacologic management approaches to post-traumatic stress disorder, suggests that first-line treatments for monotherapy are the selective serotonin reuptake inhibitors, sertraline, paroxetine and fluoxetine. Other potential options include other monotherapies including venlafaxine, mirtazapine, tricyclic antidepressants, monoamine oxidase inhibitors, as well as adjunctive usage of atypical antipsychotics, lamotrigine, trazadone and a number of adrenergic agents. A trial of therapy should be at least 8 weeks and continue for at the very least 12 months, but is likely to be much longer. In light of the risks of untreated post-traumatic stress disorder (e.g., suicide and impaired psychosocial functioning), therapy may need to be continued for 2 years or more. Pharmacologic therapy instituted at the time of acute psychologic trauma shows promise for the prevention of post-traumatic stress disorder in the future and warrants further study.

Abstract
Post-traumatic stress disorder is an anxiety disorder that may occur after the individual is exposed to severe psychologic trauma such as combat, sexual assault, or childhood physical or sexual abuse. Chronic post-traumatic stress disorder may result in considerable psychologic pain and suffering for the individual in addition to significant functional impairment. In addition to the heterogeneity of symptoms that occur in post-traumatic stress disorder, there may also be extensive comorbidity with other anxiety disorders, mood disorders, psychotic disorders, and other psychiatric disorders. This complicates the treatment picture. Currently, accepted treatments for post-traumatic stress disorder include psychotherapy, in particular cognitive behavioral-based approaches and antidepressant medication. However, many patients are refractory to these initial treatments or have only a partial response. In light of this, may clinicians combine additional classes of psychotropic agents and different psychotherapeutic approaches to enhance treatment response. This article reviews the literature on the use of atypical antipsychotics in the treatment of post-traumatic stress disorder. Most of the research to date has involved combat veterans partially responsive or refractory to treatment, namely with antidepressants. Studies have shown improvement across post-traumatic stress disorder symptom clusters, as well as improvement in comorbid psychotic symptoms or disorders. More research is needed to confirm these recent findings and further delineate the role of atypical antipsychotics in the treatment of post-traumatic stress disorder. Currently, possible indications for their use include treatment-resistant post-traumatic stress disorder and post-traumatic stress disorder with comorbid psychotic features.

Abstract
This article reviews the off-label prescription of quetiapine in the treatment of a broad range of psychiatric disorders including obsessive-compulsive disorder, post-traumatic stress disorder, personality disorder, substance abuse, bipolar disorder (now US FDA approved), anxiety and depression. The article highlights the primary reliance on selective serotonin reuptake inhibitors (SSRIs) in the treatment of these disorders (cf bipolar disorder) and the high percentage of patients (30-60%) that do not respond to SSRIs. The studies suggest that low-dose quetiapine shows good tolerability and efficacy in patients diagnosed with these disorders, particularly in the case of treatment-resistant patients that do not respond to primary treatments including SSRIs and cognitive-behavioral therapy. Quetiapine generally appears to be very effective in trauma-related conditions by improving autonomic stability, and decreasing the stress and anxiety response that arises due to specific fears or triggers. Quetiapine also appears to be particularly useful for normalizing obsessions and compulsions, and improving low mood, irritability and aggressiveness. A greater understanding of the pharmacology of drug alternatives and the neurobiology of psychiatric disorders is required to permit a more personalized medicine approach.

Abstract
Medically ill adolescents are at increased risk for psychological distress and/or functional impairment. However, there are few research studies examining the optimal psychiatric treatments for this population. Psychiatric medication recommendations are largely based on studies of youth with a primary psychiatric disorder, adult studies, hypothesized mechanisms of action, and/or clinical experience. This paper provides evidence-informed recommendations for the psychopharmacological treatment of acutely medically ill adolescents suffering from significant psychological distress and/or functional impairment. Representing the most common problems among medically ill adolescents that are treated with psychiatric medications, recommendations are provided for anxiety and depression; iatrogenic medical trauma, inadequate sleep and insomnia; and, delirium.

Abstract
Medically ill children are often exposed to traumatizing situations within the medical setting. Approximately 25-30 % of medically ill children develop posttraumatic stress symptoms and 10-20 % of them meet criteria for posttraumatic stress disorder. Parents of medically ill children are at even higher risk for posttraumatic stress symptoms. Most children and parents will experience resolution of mild trauma symptoms without formal psychological or psychiatric treatment. Posttraumatic stress symptoms are associated with medical nonadherence, psychiatric co-morbidities, and poorer health status. Therefore, evidenced-based trauma-focused treatment is indicated for those who remain highly distressed or impaired. This paper reviews approaches to the assessment and management of pediatric iatrogenic medical trauma within a family-based framework.

Abstract
Post traumatic stress disorder (PTSD) is a chronic and debilitating mental illness. Atypical antipsychotics are often utilized for treatment of PTSD despite the limited data. The purpose of this article is to review published clinical trials of atypical antipsychotics used in the treatment of PTSD. Certain patients may benefit from therapy with an atypical antipsychotic, particularly for those with hyper-arousal or re-experiencing symptom clusters. At this time, guidelines suggest against the use of risperidone as augmentation therapy in patients with PTSD. Data are only available for olanzapine, quetiapine, and aripiprazole; however, data were conflicting, not very robust, and studies had limited sample sizes and narrow demographics. It is important to provide proper patient education and weigh the risks versus benefits of therapy with an atypical antipsychotic as metabolic side effects are well documented.

Abstract
INTRODUCTION Post-traumatic stress disorder (PTSD) is a chronic debilitating psychiatric disorder resulting from exposure to a severe traumatic stressor and an area of great unmet medical need. Advances in pharmacological treatments beyond the currently approved SSRIs are needed. AREAS COVERED Background on PTSD, as well as the neurobiology of stress responding and fear conditioning, is provided. Clinical and preclinical data for investigational agents with diverse pharmacological mechanisms are summarized. EXPERT OPINION Advances in the understanding of stress biology and mechanisms of fear conditioning plasticity provide a rationale for treatment approaches that may reduce hyperarousal and dysfunctional aversive memories in PTSD. One challenge is to determine if these components are independent or reflect a common underlying neurobiological alteration. Numerous agents reviewed have potential for reducing PTSD core symptoms or targeted symptoms in chronic PTSD. Promising early data support drug approaches that seek to disrupt dysfunctional aversive memories by interfering with consolidation soon after trauma exposure, or in chronic PTSD, by blocking reconsolidation and/or enhancing extinction. Challenges remain for achieving selectivity when attempting to alter aversive memories. Targeting the underlying traumatic memory with a combination of pharmacological therapies applied with appropriate chronicity, and in combination with psychotherapy, is expected to substantially improve PTSD treatment.

Abstract
Due to relatively recent and ongoing world events (eg, terrorist attacks, wars, and natural disasters), there has been a shift in attention from some of the more common psychiatric illnesses to one of the more elusive, namely, posttraumatic stress disorder (PTSD). PTSD is a severe, and often chronic, condition that can lead to significant morbidity and mortality. Although originally a condition seen primarily among war veterans, PTSD is now becoming more prevalent in the general community. PTSD often presents concurrently with other conditions, such as depression, bipolar, anxiety/panic disorders, and alcohol and drug abuse. Because of this, PTSD often goes unrecognized and is underdiagnosed in clinical practice. Thus, an opportunity for pharmacist intervention exists, both in the institution and in the community. With proper education and training, pharmacists can be efficient in screening for signs and symptoms of PTSD, triaging appropriate patients, and can play an integral role in managing the diverse array of drug therapy options for PTSD.

Abstract
BACKGROUND This project aimed to provide an organized, sequential, and evidence-supported approach to the pharmacotherapy of posttraumatic stress disorder (PTSD), following the format of previous efforts of the Psychopharmacology Algorithm Project at the Harvard South Shore Program. METHOD A comprehensive literature review was conducted to determine the best pharmacological choices for PTSD patients and to update the last published version (1999) of the algorithm. We focused on optimal pharmacological interventions to address the prominent symptoms of PTSD, with additional attention to the impact that common comorbidities have on treatment choices. RESULTS We found that SSRIs and SNRIs are not as effective as previously thought, and that awareness of their long-term side effects has increased. New evidence suggests that addressing fragmented sleep and nightmares can improve symptoms (in addition to insomnia) that are frequently seen with PTSD (e.g., hyperarousal, reexperiencing). Prazosin and trazodone are emphasized at this initial step; if significant PTSD symptoms remain, an antidepressant may be tried. For PTSD-related psychosis, an antipsychotic may be added. In resistant cases, two or three antidepressants may be used in sequence. Following that, or with partial improvement and residual symptomatology, augmentation may be tried; the best options are antipsychotics, clonidine, topiramate, and lamotrigine. CONCLUSION This heuristic may be helpful in producing faster symptom resolution, fewer side effects, and increased compliance.

Abstract
Atypical antipsychotics are increasingly used for treatment of anxiety disorders, either in mono- or combination therapy. This is the first review reporting on the use of atypical antipsychotics in monotherapy or augmentation in patients with primary anxiety disorders or anxiety (disorders) comorbid to schizophrenia, bipolar disorder (BPD) and major depressive disorder (MDD). We included 49 open-label trials, 32 randomized, placebo-controlled trials (RCTpls) and five randomized controlled trials without placebo arm with almost 6000 patients (open-label: 1710, randomized: 4145). An increasing number of RCTpls show promising results in 27-71% of patients with primary or comorbid anxiety disorders who were treated with monotherapy atypical antipsychotics or augmentation therapy. However, methodological flaws of included studies may limit conclusions of this review and larger placebo-controlled trials are warranted comparing standard treatment with monotherapy and augmentation therapy of atypical antipsychotics and placebo. In addition, higher dropout rates and side effects from treatment with atypical antipsychotics may limit the use of atypical antipsychotics in patients with anxiety disorders.

Abstract
Irritable bowel syndrome (IBS) and other functional gastrointestinal (GI) disorders typically defy traditional diagnostic methods based on structural abnormalities, and has led to the emergence of the discipline of neurogastroenterology or the study of the "brain-gut axis," which is based on dysregulation of neuroenteric pathways as a key pathophysiological feature of IBS. Centrally acting treatments can influence these pathways and improve the clinical manifestations of pain and bowel dysfunction associated with this disorder. To successfully implement these treatment strategies, it is important to recognize their dual effects on brain and gut, understanding the nature and severity of the GI symptoms and their psychosocial concomitants, and applying them within the context of the patient's understanding of their value.

Abstract
There is growing evidence to show that atypical antipsychotic quetiapine might exert an anxiolytic effect in patients. Nevertheless, the mechanism underlying this effect has not yet been fully explored. Like other anxiolytic drugs, quetiapine exhibits partial agonistic activity toward serotonergic 1A (5HT1A) receptors. The involvement of the serotonin system in anxiety, particularly of 5HT1A receptors, has been widely documented. In this study we have investigated whether different doses of quetiapine (5, 10, and 30 mg/kg, oral gavage) administered to C57BL6/N mice could produce an anxiolytic effect in the Vogel conflict test, a classical model of anxiety, and whether or not the selective 5HT1A antagonist WAY100635 (0.1 mg/kg, subcutaneously) might prevent such an effect. Our results show that 10 mg/kg quetiapine exhibits an anxiolytic effect, that is, at least in part, 5HT1A-mediated, because it is completely eliminated by WAY100635.

Abstract
According to the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, posttraumatic stress disorder (PTSD) is characterized by three major symptom clusters following an event that elicited fear, helplessness, or horror. This review will examine each symptom cluster of PTSD separately, giving case study examples of patients who exhibit a preponderance of a given symptom domain. We use a translational approach in describing the underlying neurobiology that is relevant to particular symptoms and treatment options, thus showing how clinical practice can benefit from current research. By focusing on symptom clusters, we provide a more specific view of individual patient's clinical presentations, in order to better address treatment needs. Finally, the review will also address potential genetic approaches to treatment as another form of individualized treatment.

Abstract
Posttraumatic stress disorder (PTSD) is an anxiety disorder experienced by combat veterans. Nighttime symptoms are often unrelieved by selective serotonin reuptake inhibitor therapy, and increased use of prazosin or quetiapine for treatment is seen. The purpose of this study was to determine the short- and long-term effectiveness and safety of prazosin versus quetiapine for treating nighttime symptoms in veteran PTSD patients. This is a historical prospective cohort study using retrospective chart review. Three hundred twenty-four patients with a diagnosis of PTSD, based on International Classification of Diseases, Ninth Revision coding, who were initially prescribed prazosin or quetiapine for nighttime symptoms were screened for inclusion. Short-term effectiveness was determined by documentation of symptomatic improvement within 6 months, and long-term effectiveness if patients continued therapy to study end date. Safety was assessed by comparing incidence of adverse drug effects causing discontinuation of either study drug. This study included 237 patients: 62 received prazosin, and 175 received quetiapine. Short-term effectiveness was similar for prazosin (61.3%) and quetiapine (61.7%; P = 0.54). However, patients prescribed prazosin were significantly more likely to continue their therapy to study end date compared with quetiapine (48.4% vs 24%; P < 0.001; odds ratio, 3.0; 95% confidence interval, 1.62-5.45), thus achieving long-term effectiveness. Alternatively, patients in the quetiapine group were more likely to discontinue therapy because of adverse effects compared with the prazosin group (34.9% vs 17.7%; P = 0.008). Because of similar rate of short-term effectiveness, superior long-term effectiveness, and lower incidence of events leading to discontinuation, compared with quetiapine, prazosin should be used first-line for treating nighttime PTSD symptoms in a veteran population.

Abstract
While auditory hallucinations (AH) are prototypic psychotic symptoms whose clinical presence is often equated with a psychotic disorder, they are commonly found among those without mental illness as well as those with nonpsychotic disorders not typically associated with hallucinations in DSM-IV. This incongruity presents a significant challenge for clinical work and efforts to revise the next iteration of the DSM. Auditory hallucinations found among "normal" people suggest that either AH are not as pathologic as they are typically taken to be, or that less-than-hallucinatory experiences are routinely mischaracterized as AH. Such hallucinations in the context of conversion disorder, trauma, sensory deprivation, and certain cultural settings strengthen an association between AH and psychopathology but suggest limited diagnostic specificity and relevance. It may be useful to think of AH like coughs-common experiences that are often, but not always, symptoms of pathology associated with a larger illness. Although these issues have been known for many years, they are rarely discussed in American psychiatry and need to be addressed in future research and clinical work.

Abstract
Despite adequate antidepressant monotherapy, the majority of depressed patients do not achieve remission. Even optimal and aggressive therapy leads to a substantial number of patients who show minimal and often only transient improvement. In order to address this substantial problem of treatment-resistant depression, a number of novel targets for antidepressant therapy have emerged as a consequence of major advances in the neurobiology of depression. Three major approaches to uncover novel therapeutic interventions are: first, optimizing the modulation of monoaminergic neurotransmission; second, developing medications that act upon neurotransmitter systems other than monoaminergic circuits; and third, using focal brain stimulation to directly modulate neuronal activity. We review the most recent data on novel therapeutic compounds and their antidepressant potential. These include triple monoamine reuptake inhibitors, atypical antipsychotic augmentation, and dopamine receptor agonists. Compounds affecting extra-monoamine neurotransmitter systems include CRF(1) receptor antagonists, glucocorticoid receptor antagonists, substance P receptor antagonists, NMDA receptor antagonists, nemifitide, omega-3 fatty acids, and melatonin receptor agonists. Focal brain stimulation therapies include vagus nerve stimulation (VNS), transcranial magnetic stimulation (TMS), magnetic seizure therapy (MST), transcranial direct current stimulation (tDCS), and deep brain stimulation (DBS).

Abstract
OBJECTIVE Few studies have compared prevalence rates of metabolic abnormalities in antipsychotic-treated patients with different psychiatric disorders, including posttraumatic stress disorder (PTSD). In this study, we examined components of metabolic syndrome among middle-aged and older patients with psychiatric disorders. METHOD In the study, 203 outpatients older than 40 years and with psychotic symptoms that needed antipsychotic treatment were enrolled. Among them, 65 had a diagnosis of schizophrenia, 56 had dementia, 49 had mood disorder, and 33 had PTSD. Clinical evaluations included medical history, use of psychotropic and other medications, adverse effects, physical examination, and clinical laboratory tests for metabolic profiles. RESULTS Overall, the prevalence rates of metabolic syndrome were 72% in patients with PTSD, 60% in those with schizophrenia, 58% in those with mood disorder, and 56% in those with dementia. There were significant differences in body mass index, diastolic blood pressure, waist circumference, and high-density lipoprotein cholesterol among the 4 diagnostic groups. Posttraumatic stress disorder, schizophrenia, and mood disorder groups had significantly higher body mass indexes compared with the dementia group. The PTSD group also had significantly higher diastolic blood pressure compared with the dementia and mood disorder groups. CONCLUSIONS Posttraumatic stress disorder may be associated with worsened metabolic profile. The overall frequency of metabolic syndrome and its components in patients with PTSD taking antipsychotics seemed to be at least equivalent, if not slightly worse, compared with that in patients with schizophrenia, dementia, or a mood disorder.

Abstract
Management of severe refractory functional gastrointestinal disorders (FGIDs) is difficult. Quetiapine, an atypical antipsychotic, may benefit patients by mitigating associated anxiety and sleep disturbances, augmenting the effect of antidepressants, and providing an independent analgesic effect. Outpatient records from a university-based FGID clinic were reviewed, and 21 patients with refractory symptoms who received quetiapine were identified and interviewed. Outcomes included global relief of symptoms, treatment efficacy questionnaire, and change in gastrointestinal (GI) and psychological symptoms. Eleven of 21 patients continued therapy at the time of interview. Six of 11 demonstrated global relief of symptoms, and 9 were satisfied with treatment. The remaining 10 of 21 discontinued therapy because of somnolence and lack of GI benefits. Quetiapine in low doses appeared beneficial in more than half of the adults with severe FGIDs who stayed on treatment. This response in otherwise refractory patients suggests quetiapine might augment the effectiveness of antidepressants in severe FGIDs.

Abstract
The selective serotonin reuptake inhibitors (SSRIs) are considered the first-line pharmacological treatment for PTSD. However, even when treated with this class of drugs, response rates rarely exceed 60% and less than 20-30% of the patients achieve full remission. The aim of this study was to address this limitation by systematically reviewing the options left for the treatment of PTSD when patients do not respond satisfactorily to or tolerate SSRIs. A systematic review covering all original articles, letters and brief reports published in any language until October 2008 was conducted through searches in the ISI/Web of Science, PubMed and PILOTS databases. The search terms included the pharmacological class of each agent or its generic name plus "PTSD" or "stress disorder" in the title, in the abstract or as a keyword. Sixty-three articles were selected, covering the following categories: antipsychotics, anticonvulsants, adrenergic-inhibiting agents, opioid antagonists, benzodiazepines and other agents. None of the identified agents reached the level A of scientific evidence, 5 reached level B, 7 level C and 13 level D. The non-antidepressant agent with the strongest scientific evidence supporting its use in PTSD is risperidone, which can be envisaged as an effective add-on therapy when patients did not fully benefit from previous treatment with SSRIs. Prazosin, an adrenergic-inhibiting agent, is a promising alternative for cases of PTSD where nightmares and insomnia are prominent symptoms. So far, there is no consistent empirical support for using benzodiazepines in the prevention or in the treatment of PTSD, although these drugs could alleviate some associated non-specific symptoms, such as insomnia or anxiety. Further controlled clinical trials and meta-analysis are needed to guide clinicians in their search of effective pharmacological alternatives to antidepressants in PTSD.

Abstract
In this report, which is an update of a guideline published in 2002 (Bandelow et al. 2002, World J Biol Psychiatry 3:171), recommendations for the pharmacological treatment of anxiety disorder, obsessive-compulsive disorder (OCD) and post-traumatic stress disorder (PTSD) are presented. Since the publication of the first version of this guideline, a substantial number of new randomized controlled studies of anxiolytics have been published. In particular, more relapse prevention studies are now available that show sustained efficacy of anxiolytic drugs. The recommendations, developed by the World Federation of Societies of Biological Psychiatry (WFSBP) Task Force for the Pharmacological Treatment of Anxiety, Obsessive-Compulsive and Post-traumatic Stress Disorders, a consensus panel of 30 international experts, are now based on 510 published randomized, placebo- or comparator-controlled clinical studies (RCTs) and 130 open studies and case reports. First-line treatments for these disorders are selective serotonin reuptake inhibitors (SSRIs), serotonin-noradrenaline reuptake inhibitors (SNRIs) and the calcium channel modulator pregabalin. Tricyclic antidepressants (TCAs) are equally effective for some disorders, but many are less well tolerated than the SSRIs/SNRIs. In treatment-resistant cases, benzodiazepines may be used when the patient does not have a history of substance abuse disorders. Potential treatment options for patients unresponsive to standard treatments are described in this overview. Although these guidelines focus on medications, non-pharmacological were also considered. Cognitive behavioural therapy (CBT) and other variants of behaviour therapy have been sufficiently investigated in controlled studies in patients with anxiety disorders, OCD, and PTSD to support them being recommended either alone or in combination with the above medicines.

Abstract
Functional gastrointestinal disorders (FGIDs) are commonly seen gastrointestinal (GI) conditions that are diagnosed using established symptom-based criteria. These disorders that typically defy traditional diagnostic methods based on structural abnormalities have intrigued researchers for several decades. This has led to the emergence of the current discipline of neurogastroenterology or the study of the "brain-gut axis," which is based on dysregulation of neuroenteric pathways as a key pathophysiologic feature of the FGIDs. Psychopharmacologic and behavioral treatments can influence the dysregulation of these pathways, especially at the severe end of the spectrum, and improve the clinical manifestations of these conditions, visceral discomfort or pain and bowel dysfunction. Their actions are mostly at spinal and supraspinal levels with some direct benefits at the level of the gut. Improvements in coping, global distress, and overall quality of life (QOL) have been shown more consistently with these treatments compared with improvement in GI symptoms. A successful approach to patients with these treatments requires a good physician-patient relationship. Strategizing treatments with these modalities is based on recognition of their dual effects on brain and gut, understanding the nature and severity of the GI symptoms and their psychosocial concomitants, and applying them within the context of the patient's understanding of their value.

Abstract
BACKGROUND Generalized anxiety disorder (GAD) is a chronic disorder associated with significant morbidity and disability. Traditional therapies are associated with poor levels of remission, and often result in troublesome side effects. METHODS This was a 12-week, open-label, flexible-dose study to assess the efficacy and tolerability of quetiapine as an adjunctive treatment to traditional medication. 40 outpatients with GAD who had not achieved remission following at least 8 weeks of an adequate dose of traditional therapy were enrolled. The primary endpoint was the mean change from pre-treatment to week 12 in the Hamilton Anxiety Rating Scale (HAM-A) total scores. Secondary endpoints included: the proportion of patients achieving remission (HAM-A total score of < or =10 at week 12), Clinical Global Impressions-Severity of Illness (CGI-S), Clinical Global Impressions-Global Improvement (CGI-I), Pittsburgh Sleep Quality Index (PSQI) and Penn State Worry Questionnaire (PSWQ). RESULTS Adjunctive quetiapine (mean dose 386mg/day at week 12) significantly reduced the HAM-A total scores from pre-treatment (29.8+/-9.0) to week 12 (9.0+/-10.2) (-20.6; p<0.001). The HAM-A remission rate was 72.1% at week 12. Adjunctive quetiapine resulted in a significant reduction in all efficacy measures by study end. Quetiapine was well tolerated: the most common adverse event (AE) was sedation, with no incidence of serious AEs and no clinically significant changes in vital signs, weight (mean gain 0.5kg at week 12) or laboratory assessments. CONCLUSION The results of this small pilot trial suggest that quetiapine adjunctive to traditional therapy may be a useful treatment in patients with GAD or treatment-resistant GAD, and warrant further investigation.

Abstract
Posttraumatic stress disorder (PTSD) is a psychiatric disorder that develops after a psychological trauma usually caused by a situation perceived as deeply threatening to a person's life or integrity. Complex neurobiological changes triggered by such a traumatic and stressful experience may explain a wide range of PTSD symptoms and provide the rationale for psychopharmacological treatment. Selective serotonin-reuptake inhibitors make the first-line treatment of PTSD. Clinical experience has shown that they are more effective than noradrenalin-reuptake inhibitors or tricyclic antidepressants. Antipsychotic drugs, especially atypical ones, have been shown effective in PTSD patients with psychotic characteristics or refractoriness to other treatments. Mood stabilizers seem to reduce mostly autonomous overreactions to stress, whereas the evidence for effectiveness of monoamine oxidase inhibitors is largely inconclusive. Other groups of medications, such as serotonin agonists and antagonists, new antidepressants, dual inhibitors of serotonin- and noradrenalin-reuptake, anticonvulsants, and opiate antagonists are also sometimes used in PTSD treatment. However, as shown in the present review, most clinical studies performed to date to investigate the effectiveness of different psychopharmacological agents in the therapy of PTSD have serious limitations in terms of small sample size, lack of blinding and randomization, and small effect size. More rigorously designed, comparative studies are needed to determine the usefulness, efficacy, tolerability, and safety of particular psychopharmaceutical drugs in the treatment of this therapeutically and functionally challenging disorder.

Abstract
RATIONALE More data are needed to guide "next step" strategies for patients with generalized anxiety disorder (GAD) remaining symptomatic despite initial pharmacotherapy. OBJECTIVE This study prospectively examined the relative efficacy of quetiapine versus placebo augmentation for individuals with GAD remaining symptomatic with initial paroxetine CR pharmacotherapy. MATERIALS AND METHODS Adult outpatients with GAD were recruited from 2004 to 2007 at two academic centers. Phase 1 consisted of 10 weeks of open-label paroxetine CR flexibly dosed to a maximum of 62.5 mg/day. Those remaining symptomatic (Hamilton Anxiety Scale [HAM-A] >or= 7) at week 10 were randomized to quetiapine or placebo augmentation flexibly dosed from 25 to 400 mg/day. RESULTS For participants receiving paroxetine CR (n = 50), there was a significant reduction in HAM-A scores (baseline mean +/- SD = 22.4 +/- 4.2 to endpoint mean +/- SD = 11.2 +/- 6.9; paired t = 12.1, df = 49, t < 0.0001) with 40% (n = 20) achieving remission. Counter to our hypothesis, we did not find significant benefit for quetiapine augmentation of continued paroxetine CR (HAM-A reduction mean +/- SD = 2.6 +/- 5.8 points quetiapine, 0.3 +/- 5.5 points placebo; t = 0.98, df = 20, p = n.s.) in the randomized sample (n = 22) with relatively minimal additional improvement overall in phase 2. CONCLUSIONS Although conclusions are considered preliminary based on the relatively small sample size, our data do not support the addition of quetiapine to continued paroxetine CR for individuals with GAD who remain symptomatic after 10 weeks of prospective antidepressant pharmacotherapy and suggest that further research examining strategies for GAD refractory to antidepressants is needed.

Abstract
Data on the efficacy of quetiapine in borderline personality disorder (BPD) are still scarce. We aimed to investigate the efficacy of quetiapine for impulsivity and a broad range of affective symptoms in BPD. In this 12-week open-label study, we included individuals with BPD who presented to psychiatric in- and outpatient services. After a gradual titration of quetiapine, a flexible dose (range, 100-800 mg) was administered. The main outcome measures consisted of the scores on patient-rated questionnaires (Barratt Impulsiveness Scale, Buss-Durkee Hostility Inventory, Affective Lability Scale, Spielberger State and Trait Anxiety Inventory, Spielberger State and Trait Anger Inventory, and Beck Depression Inventory) and on neurocognitive tasks related to impulsivity (Stroop Color Word Task and IOWA Gambling Task). A mixed linear model, correcting for age, sex, antidepressant use, and weeks in psychotherapy, was applied. Forty-one patients (34 females and 7 males; mean [SD] age, 27.0 [9.0] years) were enrolled in the study, 32 of which completed the trial. Patients' scores decreased significantly (mean [SD] difference; P value) on the Barratt Impulsiveness Scale (19.7 [2.0]; P < 0.0001), Buss-Durkee Hostility Inventory (11.5 [1.4]; P < 0.0001), Affective Lability Scale (0.75 [0.08]; P < 0.0001), Beck Depression Inventory (25.0 [1.7]; P < 0.0001), Spielberger State and Trait Anxiety Inventory state (19.9 [1.9]; P < 0.0001) and trait (20.8 [1.7]; P < 0.0001) subscale, and Spielberger State and Trait Anger Inventory state (7.3 [1.1]; P < 0.0001) and trait (10.1 [1.0]; P < 0.0001) subscale. In addition, patients showed significantly less inference on the Stroop Color Word Task and had more 'good choices' on the IOWA Gambling Task. These results suggest that quetiapine may be efficacious in the treatment of impulsivity and affective symptoms in BPD.

Abstract
This double-blind, placebo-controlled study examined the efficacy and tolerability of quetiapine in combination with selective serotonin reuptake inhibitors (SSRIs)/venlafaxine in 58 patients with major depressive disorder, comorbid anxiety symptoms (HAM-A-14 score > or =14), and residual depressive symptoms (HAM-D-17 score > or =18, CGI-S score > or =4). Patients had received an SSRI/venlafaxine (at a predefined therapeutic dose) for > or =6 weeks. Overall, 62% (18/29) of quetiapine- and 55% (16/29) of placebo-treated patients completed the study. The mean change in HAM-D and HAM-A total scores from baseline to Week 8 (primary endpoint) was significantly greater with quetiapine (mean dose 182 mg/day) than placebo: -11.2 vs. -5.5 (P=.008) and -12.5 vs. -5.9 (P=.002), respectively. The onset of quetiapine efficacy (HAM-D/HAM-A/CGI-I) was rapid (by Week 1) and continued through to Week 8. Significant differences (P<.05) from baseline to Week 8 were observed between groups in 7/17 HAM-D (including feelings of guilt, suicide) and 6/14 HAM-A items (including tension, cardiovascular symptoms). Response (> or =50% decrease in total score) was higher for quetiapine than placebo: HAM-D, 48% vs. 28% (not significant, NS); HAM-A, 62% vs. 28% (P=.02). Remission (total score < or =7) was higher for quetiapine than placebo: HAM-D, 31% vs. 17% (NS); HAM-A, 41% vs. 17% (NS). CGI-S, CGI-I, and the Global Assessment Scale showed that quetiapine was significantly more effective than placebo. For quetiapine, adverse events (AEs) were similar to those previously observed; sedation/somnolence/lethargy was the most commonly reported. Here quetiapine was shown to be effective as augmentation of SSRI/venlafaxine therapy in patients with major depression, comorbid anxiety, and residual depressive symptoms, with no unexpected tolerability issues. Further studies are warranted.

Abstract
OBJETIVOS: Nesta revisão narrativa, o objetivo foi descrever as opções farmacológicas para o tratamento do transtorno de estresse pós-traumático nos casos de intolerância, resistência, refratariedade ou impossibilidade de utilizar antidepressivos, especialmente inibidores seletivos da recaptação da serotonina. MÉTODO: Consulta às bases de dados ISI Web of Science e PubMed em busca de estudos originais sobre o tratamento farmacológico do transtorno de estresse pós-traumático em diferentes cenários clínicos. RESULTADOS: Evidências preliminares apontam para a utilidade de drogas como a risperidona, a olanzapina, a lamotrigina e o prazosin como estratégias para o cenário clínico em tela. A escolha do medicamento de segunda linha deve levar em conta não só os sintomas, como também as comorbidades, os tratamentos prévios, as interações farmacológicas, os efeitos colaterais e as condições físicas do paciente. CONCLUSÕES: Futuros ensaios clínicos randomizados ainda são necessários para estabelecer com clareza alternativas farmacológicas aos antidepressivos para o tratamento do transtorno de estresse pós-traumático.

Abstract
Post-traumatic stress disorder (PTSD) is often a chronic and disabling anxiety disorder that develops after exposure to a traumatic event. Researchers have demonstrated efficacy for both pharmacologic and psychosocial interventions in the treatment of PTSD. First-line pharmacotherapeutic options are the selective serotonin re-uptake inhibitors and serotonin noradrenaline re-uptake inhibitors. Older antidepressant agents, such as the tricyclic antidepressants and the monoamine oxidase inhibitor, phenelzine, have also proven efficacy in PTSD among more established agents. However, concerns for side effects have limited frequent use of these. Existing pharmacologic agents produce meaningful results and bear the advantage of treating depression and other co-morbid disorders, yet still fall short of being ideal due to limited response and remission rates and tolerability issues. The need for improving pharmacotherapy of PTSD remains compelling and directions for further research are discussed.

Abstract
Sleep disturbances are core symptoms of posttraumatic stress disorder (PTSD) and are often resistant to treatment. One reason for the recent use of atypical antipsychotics in PTSD appears to be their effects on sleep. Study objectives were (1) to evaluate preliminarily the sleep effects of adjunctive risperidone, and (2) to evaluate the use of sleep diaries versus the more standard retrospective sleep assessments. This was a pilot, open-label, 12-week, flexible-dose trial of adjunctive risperidone in male veterans with a primary diagnosis of chronic, combat-related PTSD, partially responsive to current medications. Diagnostic interviews were administered at baseline, and PTSD ratings were obtained at baseline and at 6 and 12 weeks. Self-report sleep measures, including morning logs, were obtained at baseline and 6 weeks. Seventeen patients completed at least 6 weeks of the trial. Global ratings of sleep disturbance improved. Changes in frequency of awakenings and reductions in trauma-related dreams were only evident via morning log assessments. Nighttime awakening frequency derived from the sleep logs but not from the Pittsburgh Sleep Quality Index (PSQI) decreased significantly. There were no changes in the PSQI nightmare item; however, sleep log data indicated a reduced proportion of traumatic dreams at 6 weeks. Preliminary results suggest that adjunctive risperidone may benefit sleep disturbances associated with chronic PTSD. Prospective logs may be more sensitive to change than are retrospective scales.

Abstract
Established treatments for depression are often effective. However, a significant number of patients show limited or no response. With advancements in the explanation of the underlying neurobiology of depression, several novel therapeutic approaches have been developed. Emerging drug targets include novel monoamine oxidase inhibitors, triple monoamine re-uptake inhibitors, omega-3 fatty acids, melatoninergic agonists and receptor antagonists for corticotropin-releasing factor(1), glucocorticoid, substance-P and NMDA. Developments in therapeutic focal brain stimulation include vagus nerve stimulation, transcranial magnetic stimulation, magnetic seizure therapy and deep brain stimulation. The role of psychotherapy, both as monotherapy and as adjunctive therapy, is an active avenue of investigation. Although data on these treatments are limited, preliminary results are encouraging. A major goal that remains to be achieved is the identification of predictors of response to the various antidepressant treatments that have diverse mechanisms of action.
