AbstractPosttraumatic stress disorder (PTSD) is a debilitating psychiatric disorder with limited approved pharmacological treatment options and high symptom burden. Therefore, real-life prescription patterns may differ from guideline recommendations, especially in psychiatric inpatient settings. The European Drug Safety Program in Psychiatry (“Arzneimittelsicherheit in der Psychiatrie”, AMSP) collects inpatients’ prescription rates cross-sectionally twice a year in German-speaking psychiatric hospitals. For this study, the AMSP database was screened for psychiatric inpatients with a primary diagnosis of PTSD between 2001 and 2017. N = 1,044 patients with a primary diagnosis of PTSD were identified with 89.9% taking psychotropics. The average prescription rate was 2.4 (standard deviation: 1.5) psychotropics per patient with high rates of antidepressant drugs (72.0%), antipsychotics drugs (58.4%) and tranquilizing drugs (29.3%). The presence of psychiatric comorbidities was associated with higher rates of psychotropic drug use. The most often prescribed substances were quetiapine (24.1% of all patients), lorazepam (18.1%) and mirtazapine (15.0%). The use of drugs approved for PTSD was low (sertraline 11.1%; paroxetine 3.7%). Prescription rates of second-generation antipsychotic drugs increased, while the use of tranquilizing drugs declined over the years. High prescription rates and extensive use of sedative medication suggest a symptom-driven prescription (e.g., hyperarousal, insomnia) that can only be explained to a minor extent by existing comorbidities. The observed discrepancy with existing guidelines underlines the need for effective pharmacological and psychological treatment options in psychiatric inpatient settings.

Objectives: Posttraumatic stress disorder (PTSD) is a prevalent, chronic, disabling disorder that may develop following exposure to a traumatic event. This review summarizes currently used animal models of PTSD and their potential role in the development of better therapeutics. Heterogeneity is one of the main characteristics of PTSD with the consequence that many pharmacological approaches are used to relieve symptoms of PTSD. To address the translational properties of the animal models, we discuss the types of stressors used, the rodent correlates of human PTSD (DSM-5) symptoms, and the efficacy of approved, recommended and off-label drugs used to treat PTSD in ‘PTSD-animals’. Conclusions: Currently available animal models reproduce most PTSD symptoms and are validated by existing therapeutics. However, novel therapeutics are needed for this disorder as not one drug alleviates all symptoms and many have side effects that lead to non-compliance among PTSD patients. The true translational power of animal models of PTSD will only be demonstrated when new therapeutics acting through novel mechanisms become available for clinical practice.

Experiencing an extremely traumatic event, such as combat or violent assault can lead to posttraumatic stress disorder (PTSD), the fourth most common psychiatric diagnosis. It is defined by reexperiencing, hyperarousal, and avoidance symptom clusters following an event that elicited fear, helplessness, or horror. As a disorder which is in part explained by disruption of normal fear regulation, it provides a particularly interesting and exciting intersection of the molecular neurobiology of fear processing that is being rapidly understood in animal models. This chapter reviews some aspects of convergence from preclinical studies with human neuroimaging, neurophysiology, and genetic approaches as well as current and new treatment approaches.

Introduction: Because of the high prevalence of exposure to traumatic events and its negative consequences on mental health, the importance of effective interventions to prevent posttraumatic stress disorder has been emphasized. Aim: The authors wanted to evaluate the current status of evidence regarding early psychological interventions after traumatization. Method: A search was conducted in ProQuest PILOTS, PubMed, and Web of Science for early psychological interventions that were published between 2005 and 2015. Results: Twenty-one trials were identified, of which 6 presented immediate interventions (within 72 hours) and the rest early interventions within the first month. Based on these research findings immediate interventions are not effective, whilst multi-session cognitive behavior therapies could be effective in symptom reduction. Conclusions: Multi-session cognitive behavior therapy is preferred over immediate one session interventions especially over debriefing. A natural decline of symptoms was observed among controls and, therefore, targeted interventions are recommended only for people with higher risk for developing subsequent posttraumatic stress disorder.
