Abstract
BACKGROUND Posttraumatic stress disorder (PTSD) is a prevalent and disabling disorder. Evidence that PTSD is characterised by specific psychobiological dysfunctions has contributed to a growing interest in the use of medication in its treatment. OBJECTIVES To assess the effects of medication for reducing PTSD symptoms in adults with PTSD. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL; Issue 11, November 2020); MEDLINE (1946-), Embase (1974-), PsycINFO (1967-) and PTSDPubs (all available years) either directly or via the Cochrane Common Mental Disorders Controlled Trials Register (CCMDCTR). We also searched international trial registers. The date of the latest search was 13 November 2020. SELECTION CRITERIA All randomised controlled trials (RCTs) of pharmacotherapy for adults with PTSD. DATA COLLECTION AND ANALYSIS Three review authors (TW, JI, and NP) independently assessed RCTs for inclusion in the review, collated trial data, and assessed trial quality. We contacted investigators to obtain missing data. We stratified summary statistics by medication class, and by medication agent for all medications. We calculated dichotomous and continuous measures using a random-effects model, and assessed heterogeneity. MAIN RESULTS We include 66 RCTs in the review (range: 13 days to 28 weeks; 7442 participants; age range 18 to 85 years) and 54 in the meta-analysis. For the primary outcome of treatment response, we found evidence of beneficial effect for selective serotonin reuptake inhibitors (SSRIs) compared with placebo (risk ratio (RR) 0.66, 95% confidence interval (CI) 0.59 to 0.74; 8 studies, 1078 participants), which improved PTSD symptoms in 58% of SSRI participants compared with 35% of placebo participants, based on moderate-certainty evidence. For this outcome we also found evidence of beneficial effect for the noradrenergic and specific serotonergic antidepressant (NaSSA) mirtazapine: (RR 0.45, 95% CI 0.22 to 0.94; 1 study, 26 participants) in 65% of people on mirtazapine compared with 22% of placebo participants, and for the tricyclic antidepressant (TCA) amitriptyline (RR 0.60, 95% CI 0.38 to 0.96; 1 study, 40 participants) in 50% of amitriptyline participants compared with 17% of placebo participants, which improved PTSD symptoms. These outcomes are based on low-certainty evidence. There was however no evidence of beneficial effect for the number of participants who improved with the antipsychotics (RR 0.51, 95% CI 0.16 to 1.67; 2 studies, 43 participants) compared to placebo, based on very low-certainty evidence. For the outcome of treatment withdrawal, we found evidence of a harm for the individual SSRI agents compared with placebo (RR 1.41, 95% CI 1.07 to 1.87; 14 studies, 2399 participants). Withdrawals were also higher for the separate SSRI paroxetine group compared to the placebo group (RR 1.55, 95% CI 1.05 to 2.29; 5 studies, 1101 participants). Nonetheless, the absolute proportion of individuals dropping out from treatment due to adverse events in the SSRI groups was low (9%), based on moderate-certainty evidence. For the rest of the medications compared to placebo, we did not find evidence of harm for individuals dropping out from treatment due to adverse events. AUTHORS' CONCLUSIONS The findings of this review support the conclusion that SSRIs improve PTSD symptoms; they are first-line agents for the pharmacotherapy of PTSD, based on moderate-certainty evidence. The NaSSA mirtazapine and the TCA amitriptyline may also improve PTSD symptoms, but this is based on low-certainty evidence. In addition, we found no evidence of benefit for the number of participants who improved following treatment with the antipsychotic group compared to placebo, based on very low-certainty evidence. There remain important gaps in the evidence base, and a continued need for more effective agents in the management of PTSD.

Abstract
Two cognitive-behavioral approaches to the reduction of emotional trauma were combined and used successfully to treat a police officer in eight individual sessions. Elements of critical incident stress management were added to a constructive narrative approach, yielding a therapeutic frameworkthat helped the officer view traumatic events experienced in the line of duty as formative. Several educational factors also characterized this case. These include the need to understand first responder professions within a quasicultural context, the impact of past physical and sexual abuse, and factors to consider when working with children of deaf parents.

Abstract
This study evaluated the efficacy of pregabalin augmentation of antidepressant treatment in patients with posttraumatic stress disorder (PTSD). Nine patients meeting Diagnostic and Statistical Manual, fourth edition criteria for PTSD who were on stable doses of antidepressants were treated open label with flexibly dosed pregabalin for 6 weeks. All patients were assessed with the Short PTSD Rating Interview, Montgomery-Asberg Depression Rating Scale, Patient Global Impression-severity, Visual Analog Scale-pain, and Sheehan Disability Scale at baseline and weeks 2, 4, and 6. Significant reductions were observed in all effectiveness measures from week 4 to the end of the study. In particular, the numerical improvement of the Visual Analog Scale-pain score was most robust (-53.4%, P=0.007). Pregabalin augmentation was effective and well tolerated during the study. Our findings warrant adequately powered, placebo-controlled clinical trials to confirm the usefulness of pregabalin augmentation of antidepressants in patients with PTSD.

Abstract
Monoamine oxidases (MAOs) A and B are mitochondrial bound isoenzymes which catalyze the oxidative deamination of dietary amines and monoamine neurotransmitters, such as serotonin, norepinephrine, dopamine, beta-phenylethylamine and other trace amines. The rapid degradation of these molecules ensures the proper functioning of synaptic neurotransmission and is critically important for the regulation of emotional behaviors and other brain functions. The byproducts of MAO-mediated reactions include several chemical species with neurotoxic potential, such as hydrogen peroxide, ammonia and aldehydes. As a consequence, it is widely speculated that prolonged excessive activity of these enzymes may be conducive to mitochondrial damages and neurodegenerative disturbances. In keeping with these premises, the development of MAO inhibitors has led to important breakthroughs in the therapy of several neuropsychiatric disorders, ranging from mood disorders to Parkinson's disease. Furthermore, the characterization of MAO knockout (KO) mice has revealed that the inactivation of this enzyme produces a number of functional and behavioral alterations, some of which may be harnessed for therapeutic aims. In this article, we discuss the intriguing hypothesis that the attenuation of the oxidative stress induced by the inactivation of either MAO isoform may contribute to both antidepressant and antiparkinsonian actions of MAO inhibitors. This possibility further highlights MAO inactivation as a rich source of novel avenues in the treatment of mental disorders.

Abstract
BACKGROUND Post traumatic stress disorder (PTSD) is a prevalent and disabling disorder. Evidence that PTSD is characterised by specific psychobiological dysfunctions has contributed to a growing interest in the use of medication in its treatment. OBJECTIVES To assess the effects of medication for post traumatic stress disorder. SEARCH STRATEGY We searched the Cochrane Depression, Anxiety and Neurosis Group specialised register (CCDANCTR-Studies) on 18 August 2005, the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library issue 4, 2004), MEDLINE (January 1966 to December 2004), PsycINFO (1966 to 2004), and the National PTSD Center Pilots database. Reference lists of retrieved articles were searched for additional studies. SELECTION CRITERIA All randomised controlled trials (RCTs) of pharmacotherapy for PTSD. DATA COLLECTION AND ANALYSIS Two raters independently assessed RCTs for inclusion in the review, collated trial data, and assessed trial quality. Investigators were contacted to obtain missing data. Summary statistics were stratified by medication class, and by medication agent for the selective serotonin reuptake inhibitors (SSRIs). Dichotomous and continuous measures were calculated using a random effects model, heterogeneity was assessed, and subgroup/sensitivity analyses were undertaken. MAIN RESULTS 35 short-term (14 weeks or less) RCTs were included in the analysis (4597 participants). Symptom severity for 17 trials was significantly reduced in the medication groups, relative to placebo (weighted mean difference -5.76, 95% confidence intervals (CI) -8.16 to -3.36, number of participants (N) = 2507). Similarly, summary statistics for responder status from 13 trials demonstrated overall superiority of a variety of medication agents to placebo (relative risk 1.49, 95% CI 1.28 to 1.73, number needed to treat = 4.85, 95% CI 3.85 to 6.25, N = 1272). Medication and placebo response occurred in 59.1% (N = 644) and 38.5% (628) of patients, respectively. Of the medication classes, evidence of treatment efficacy was most convincing for the SSRIs. Medication was superior to placebo in reducing the severity of PTSD symptom clusters, comorbid depression and disability. Medication was also less well tolerated than placebo. A narrative review of 3 maintenance trials suggested that long term medication may be required in treating PTSD. AUTHORS' CONCLUSIONS Medication treatments can be effective in treating PTSD, acting to reduce its core symptoms, as well as associated depression and disability. The findings of this review support the status of SSRIs as first line agents in the pharmacotherapy of PTSD, as well as their value in long-term treatment. However, there remain important gaps in the evidence base, and a continued need for more effective agents in the management of PTSD.

Abstract
Few studies for the long-term effects of antidepressants on post-traumatic stress disorder (PTSD) have been conducted. The aim of the present study was to investigate the effectiveness of mirtazapine during the 24-week continuation treatment in patients with PTSD. Out of 15 patients who participated in the previous 8-week short-term study, 12 patients completed 24-week continuation treatment with mirtazapine. The effectiveness was evaluated at week 12 and week 24 using Impact of Event Scale-Revised (IES-R), Short PTSD Rating Interview (SPRINT), Interviewer-Administered Structured Interview for PTSD (SIP) and Montgomery-Asberg Depression Rating Scale (MADRS). The tolerability of continuation treatment was also reported. The scores on the IES-R, SPRINT, SIP and MADRS were significantly reduced over time from baseline to week 24, the end-point (F=36.1, d.f.=4, P<0.001; F=106.3, d.f.=4, P<0.001; F=121.1, d.f.=4, P<0.001; F=198.9, d.f.=4, P<0.001). On post-hoc analysis, the scores of all four measures were significantly reduced at the end point since week 8. However, after Bonferroni's correction, that was statistically significant in SPRINT only. The number of patients whose scores were reduced over 50% in all four scales had a tendency of incremental increase from three at week 8 to eight at the end point (P=0.063). No serious drug-related side-effects occurred. These results suggest that the mirtazapine may be effective in the continuation treatment of PTSD as well as short-term treatment. Further and better-designed studies are necessary.

Abstract
BACKGROUND Clonazepam is widely used for the treatment of posttraumatic stress disorder (PTSD)-related sleep disturbances despite very limited published data supporting its use for this indication. OBJECTIVE We conducted a pilot-controlled trial to provide more data on this clinical practice and lay the foundation for more definitive studies. METHODS The study was designed as a randomized, single-blind (ie, patient only), placebo-controlled, crossover clinical trial involving administration of clonazepam 1 mg at bedtime for one week followed by 2 mg at bedtime for one week. The following week served as a washout period before the alternate treatment was begun. Patients completed sleep diaries each morning upon awakening throughout the study. Parameters included quantity of sleep, quality of sleep, frequency and intensity of difficulty falling or staying asleep, and frequency and intensity of recurrent distressing dreams. RESULTS Six patients with combat-related PTSD participated in the study. There were no statistically significant differences between clonazepam and placebo for any measure, although clonazepam therapy resulted in mild to moderate numeric improvements in difficulty falling or staying asleep. Adverse effects of clonazepam were generally mild and essentially indiscernible from those attributed to placebo. Only one patient elected to receive further treatment with clonazepam at the conclusion of the trial. CONCLUSIONS Clonazepam therapy was largely ineffective in improving sleep disturbances, particularly nightmares, associated with combat-related PTSD. The small sample size was a significant limitation of this study, but the prospective design and single-blind, placebo-control parameters were strengths. Further studies are needed to further define the role of this widespread clinical practice.

Abstract
The pharmacotherapy of burn care has evolved from the first topical antibiotics instituted > 30 years ago. These have helped greatly to reduce the incidence of burn wound sepsis, but a better understanding of the principles of burn care has resulted in earlier burn wound excision and complete coverage with autograft, cadaver skin, synthetic dressings, and amnion. This has markedly reduced septic complications and ameliorated the hypermetabolic response to burn injury. The hypermetabolic response, which is mediated by hugely increased levels of circulating catecholamines, prostaglandins, glucagon and cortisol, causes profound skeletal muscle catabolism, immune deficiency, peripheral lipolysis, reduced bone mineralisation, reduced linear growth, and increased energy expenditure. Supportive therapy and pharmacological manipulation, acutely and during rehabilitation, with growth hormone, insulin and related proteins, oxandrolone and propranolol can ameliorate the hypermetabolic response, improving survival and long-term outcome. Despite judicious use of topical and systemic antibiotics, opportunistic nosocomial bacterial resistance threatens to annul the improved survival of patients with severe burns. Patterns of emerging resistance encountered in burn units need to be considered, in light of a decreasing antibiotic armamentarium. A holistic approach to pharmacotherapy of severely burned patients including current practice in antimicrobial control, analgesia, sedation, and anxiety management is required. Current therapy of frequently encountered problems, such as post-burn pruritus, prophylaxis of deep venous thrombosis and peptic ulceration, and pharmacological manipulation of inhalation injury in the burned patient is described. Current pharmacotherapy to ameliorate psychosocial problems associated with burns such as acute stress disorder, depression and post traumatic stress disorder are discussed. Better analgesics, newer antibiotics and immune stimulating drugs are required to reduce mortality and morbidity in large burns.

Abstract
This study was aimed at testing the efficacy and tolerability of mirtazapine in the treatment of Korean patients with chronic post-traumatic stress disorder (PTSD). Mirtazapine was administered for 8 weeks using a flexible-dose regime in 15 Korean patients with PTSD based on the DSM-IV criteria. We evaluated the patients at baseline and at weeks 4 and 8 after treatment with the interviewer-administered structured interview for PTSD (SIP), short PTSD rating interview (SPRINT), impact of event scale-revised (IES-R) and the Montgomery Asberg depression rating scale (MADRS). Scores on the SIP, SPRINT, IES-R and MADRS had significantly reduced after 8 weeks treatment. In this pilot study, mirtazapine was found to be effective and well tolerated in the treatment of patients with PTSD. This calls for further evaluation of the effect of this drug on subjects with PTSD with randomized placebo-controlled studies.

Abstract
BACKGROUND Posttraumatic stress disorder (PTSD) is a prevalent and disabling disorder. By definition prior psychological trauma plays a causal role in the disorder, and psychotherapy is a widely accepted intervention. Nevertheless there is growing evidence that PTSD is characterized by specific psychobiological dysfunctions, and this has contributed to a growing interest in the use of medication in its treatment. OBJECTIVES The authors aimed to undertake a systematic review of randomized controlled trials (RCTs) of the pharmacotherapy of posttraumatic stress disorder (PTSD) following the guidelines and using the software of the Cochrane Collaboration, and to provide an estimate of the effects of medication in this disorder. Secondary objectives were to explore questions about whether particular classes of medication are more effective and/or acceptable than others in the treatment of PTSD, and about which factors (clinical and methodological) predict response to pharmacotherapy. SEARCH STRATEGY Studies of the pharmacotherapy of PTSD were identified using literature searches of MEDLINE (1966 to 1999, using the textwords posttraumatic, post-traumatic, medication, pharmacotherapy) and other electronic databases (PSYCLIT; National PTSD Center Pilots database; Dissertation Abstracts; Cochrane Collaboration Depression, Anxiety & Neurosis Controlled Trials Register). In addition, published and unpublished RCTs were requested from PTSD researchers and pharmaceutical companies. An initial broad strategy was undertaken to find not only RCTs, but also open-label trials and reviews of the pharmacotherapy of PTSD; additional studies were sought in reference lists of retrieved articles and included studies in any language. SELECTION CRITERIA All RCTs of PTSD (including both placebo controlled and comparative trials), whether published or unpublished, but completed prior to the end of 1999 were considered for the review. DATA COLLECTION AND ANALYSIS Selected RCTs were independently assessed and collated by 2 raters, and Review Manager (RevMan) software was used to capture data on treatment response and PTSD symptom ratings. Ratings of subtypes of PTSD symptoms (intrusive/re-experiencing, avoidant/numbing, hyperarousal), of comorbid symptoms (depression, anxiety), and of quality of life were included where possible. A range of additional information, which may explain possible clinical and methodological heterogeneity amongst the trials, was also captured. Summary statistics for dichotomous and continous measures were calculated, heterogeneity was assessed, and subgroup/sensitivity analyses undertaken. MAIN RESULTS 15 short-term (12 weeks or less) RCTs were found, of which 9 had sufficient data for inclusion in the analysis. Methodological limitations were particularly apparent in early work; these included short (5 weeks or less) duration of trials and a reliance on self-report scales (rather than use of standardized clinician-rated scales). Despite these and other potentially important differences between the trials, many trials demonstrated efficacy for medication over placebo. Summary statistics were calculated for the Clinical Global Impressions scale change item (CGI-C) or close equivalent from 10 sets of data including various antidepressants and other agents - the proportion of non-responders was lower in the pharmacotherapy group than in the control group (relative risk (95% CI) = 0.72 (0.64, 0.83)). Similarly, summary statistics for the intrusion, avoidance and total scales of the Impact of Events Scale (IES) from 4sets of data again including various agents showed a statistically (and clinically) significant difference between medication and placebo (Weighted Mean Difference (95% CI) = -3.81 (-6.72,-0.91), -3.31(-5.24,-1.37), -7.18 (-11.86,-2.50) respectively). REVIEWER'S CONCLUSIONS Medication treatments can be effective in PTSD, acting to reduce its core symptoms, and should be considered as part of the treatment of this disorder. The existing evidence base does not provide sufficient data to suggest particular predictors of response to treatment, or to demonstrate that any particular class of medication is more effective or better tolerated than any other. However, the largest trials showing efficacy to date have been with the SSRIs, and in contrast, there have been negative studies of some agents. Given the high prevalence and enormous personal and societal costs of PTSD, there is a need for additional controlled trials in this area. Additional questions for future research include the effects of medication on quality of life in PTSD, appropriate dose and duration of medication, the use of medication in different trauma groups, in pediatric and geriatric subjects, and the value of early (prophylactic), combined (with psychotherapy), and long-term (maintenance) medication treatment.
