Abstract
Tricyclic antidepressants (TCAs) remain widely prescribed for depression and many other conditions. There may be important differences between individual TCA in regard to their overdose toxicity and their cardiac toxicity in clinical use. We conducted a systematic review to compare the toxicity of individual TCA in overdose and the risk of serious adverse cardiac events occurring with therapeutic doses. We used the fatal toxicity index (FTI) and case fatality ratio as markers of fatality in overdose, and hazard ratios or odds ratios for the risk of cardiovascular adverse events during normal clinical use. In all, 30 reports of mortality in overdose and 14 observational studies assessing the risk of cardiovascular adverse events in clinical use were included. FTI values were of the same order of magnitude (101-102) for all TCAs except lofepramine. Desipramine appears to be somewhat more likely than other TCAs to lead to death in overdose. Amitriptyline, clomipramine, dothiepin/dosulepin, doxepin, trimipramine and imipramine showed broadly similar toxicity and were usually reported to be less toxic than desipramine. Data on nortriptyline were contradictory. Lofepramine had the lowest risk of death in overdose. The rank order of overdose toxicity was broadly consistent between different FTI definitions and between markers used. With respect to the risk of cardiovascular events at clinically relevant exposure, amitriptyline, nortriptyline and lofepramine were associated with a greater risk of in-use cardiotoxicity. All measures of overdose toxicity were subject to external influences and confounding. The continued use of TCAs in depression and other conditions should be minimized when considering their undoubted toxicity in overdose and possible toxicity in normal clinical use.

Abstract
Cocaine and antidepressants rank high globally in substance consumption, emphasizing their impact on public health. The determination of these compounds and related substances in biological samples is crucial for forensic toxicology. This study focused on developing an innovative analytical method for the determination of cocaine, antidepressants, and their related metabolites in postmortem blood samples, using unmodified commercial Fe3O4 nanoparticles as a sorbent for dispersive magnetic solid-phase extraction (m-d-SPE), coupled with liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) analysis. An aliquot of 100 µL of whole blood and 5 µL of the internal standard pool were added to 30 mg of nanoparticles. The nanoparticles were separated from the sample using a neodymium magnet inserted into a 3D-printed microtube rack. The liquid was then discarded, followed by desorption with 300 µL of 1/1/1 acetonitrile/methanol/ethyl acetate. The sample was vortexed and separated, and 1.5 µL of the organic supernatant was injected into the LC-MS/MS. The method was acceptably validated and successfully applied to 263 postmortem blood samples. All samples evaluated in this study were positive for at least one substance. The most frequent analyte was benzoylecgonine, followed by cocaine and cocaethylene. The most common antidepressants encountered in the analyzed samples were citalopram and fluoxetine, followed by fluoxetine's metabolite norfluoxetine. This study describes the first report of this sorbent in postmortem blood analysis, demonstrating satisfactory results for linearity, precision, accuracy, and selectivity for all compounds. The method's applicability was confirmed, establishing it as an efficient and sustainable alternative to traditional techniques for forensic casework.

Abstract
BACKGROUND The use of serotonergic antidepressants (SADs) is associated with an increase in bleeding, and their exposure during the perioperative period increases the potential bleeding risk in patients undergoing surgical operations. OBJECTIVE The purpose of this study was to compare the rates of bleeding between patients on perioperative SADs and those not on SADs in patients undergoing orthopedic surgical procedures. METHODS A retrospective cohort study was conducted with patients who were admitted to a single tertiary care county teaching hospital for orthopedic surgery. Outcomes evaluated were requirements of ≥ 2 units of packed red blood cells (PRBCs) and length of hospital stay for those requiring ≥ 2 units of PRBCs. RESULTS Of 273 patients, a significantly higher percentage of patients who received SADs required ≥ 2 units of PRBCs (19.3% vs 6.9%; P = 0.0049). Patients who required transfusion had a higher median (interquartile range [IQR]) age (79 [64-84.6] vs 65 [59-75]; P < 0.0001). The risk of requiring ≥ 2 units of PRBCs transfusion was greater for individuals having an anemia comorbidity (odds ratio [OR], 4.55; 95% CI, 1.95-10.62, P = 0.0004). Patients who required ≥ 2 units of PRBCs had a longer median hospital stay than those who did not receive ≥ 2 units of PRBCs (8 [5-10.1] vs 4 [3-5]; P < 0.0001). CONCLUSION AND RELEVANCE Receiving SADs in the perioperative period is associated with a higher transfusion requirement in patients undergoing orthopedic surgery. Clinicians should be aware of this increased risk for patients who are taking SADs while undergoing surgical procedures.

Abstract
INTRODUCTION In this study, we aim to determine the risk of bleeding or thrombosis with concurrent use of tyrosine kinase inhibitors (TKIs) used to treat CML, and serotonin reuptake inhibitors (SSRIs). METHODS We conducted a retrospective cohort study of patients with CP-CML cared for at Massachusetts General Hospital (MGH) between April 2016 to February 2021. Participants were included if diagnosed with CP-CML and began TKI treatment (imatinib, dasatinib, nilotinib, bosutinib, or ponatinib) after April 2016. RESULTS One hundred patients were evaluated, eighty of whom were taking TKIs only (median age 55, 40% female), and twenty were taking TKI and SSRI concomitantly (median age 53.5, 55% female). Baseline demographics between these groups were similar across all variables. Patients in the TKI only group had 9 bleeding events and 3 thrombotic events. Patients in the combination group had 6 bleeding events and 1 thrombotic event. There was no difference between overall rates of major bleeding (4% v. 10%, p = 0.26) or thrombotic events (4% v. 5%, p = 1). However, patients in the combination group were more likely to have major intracranial bleeding events (0% v. 10%, p = 0.04), and there was a trend to significance for minor bleeding events (7.5% v. 20%, p = 0.11). CONCLUSIONS Concomitant use of TKIs and SSRIs does not appear to increase the total risk of bleeding or thrombotic events compared to patients on TKIs only. However, concomitant use of TKIs and SSRIs may increase risk of intracranial bleeding. Further work is needed to fully assess this risk.

A Focus on Abuse/Misuse and Withdrawal Issues with Selective Serotonin Reuptake Inhibitors (SSRIs): Analysis of Both the European EMA and the US FAERS Pharmacovigilance Databases. Pharmaceuticals (Basel) 2022; 15:ph15050565. [PMID: 35631391 PMCID: PMC9146999 DOI: 10.3390/ph15050565] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2022] [Revised: 04/29/2022] [Accepted: 04/29/2022] [Indexed: 02/04/2023] Open
Abstract
Despite increasing reports, antidepressant (AD) misuse and dependence remain underestimated issues, possibly due to limited epidemiological and pharmacovigilance evidence. Thus, here we aimed to determine available pharmacovigilance misuse/abuse/dependence/withdrawal signals relating to the Selective Serotonin Reuptake Inhibitors (SSRI) citalopram, escitalopram, paroxetine, fluoxetine, and sertraline. Both EudraVigilance (EV) and Food and Drug Administration-FDA Adverse Events Reporting System (FAERS) datasets were analysed to identify AD misuse/abuse/dependence/withdrawal issues. A descriptive analysis was performed; moreover, pharmacovigilance measures, including the reporting odds ratio (ROR), the proportional reporting ratio (PRR), the information component (IC), and the empirical Bayesian geometric mean (EBGM) were calculated. Both datasets showed increasing trends of yearly reporting and similar signals regarding abuse and dependence. From the EV, a total of 5335 individual ADR reports were analysed, of which 30% corresponded to paroxetine (n = 1592), 27% citalopram (n = 1419), 22% sertraline (n = 1149), 14% fluoxetine (n = 771), and 8% escitalopram (n = 404). From FAERS, a total of 144,395 individual ADR reports were analysed, of which 27% were related to paroxetine, 27% sertraline, 18% citalopram, 16% fluoxetine, and 13% escitalopram. Comparing SSRIs, the EV misuse/abuse-related ADRs were mostly recorded for citalopram, fluoxetine, and sertraline; conversely, dependence was mostly associated with paroxetine, and withdrawal to escitalopram. Similarly, in the FAERS dataset, dependence/withdrawal-related signals were more frequently reported for paroxetine. Although SSRIs are considered non-addictive pharmacological agents, a range of proper withdrawal symptoms can occur well after discontinuation, especially with paroxetine. Prescribers should be aware of the potential for dependence and withdrawal associated with SSRIs.

Abstract
BACKGROUND The most immediate response of the research community to COVID-19 has been a focus on understanding the effects, treatment and prevention of infection. Of equal and ongoing importance is elucidating the impact of mitigation measures, such as lockdown, on the well-being of societies. Research about mental health and lockdown in the UK has predominately involved large surveys that are likely to encounter self-selection bias. Further, self-reporting does not constitute a clinical judgement. AIMS To (a) compare the age, gender and ethnicity of patients experiencing mental health emergencies prior compared with during lockdown, (b) determine whether the nature of mental health emergencies has changed during compared with before lockdown, (c) explore the utility of emergency medical service data for identifying vulnerability to mental health emergencies in real time during a pandemic. METHOD A total of 32 401 clinical records of ambulance paramedics attending mental health emergencies in the East Midlands of the UK between 23 March and 31 July 2020 and the same period in 2019 were analysed using binary logistic regression. RESULTS People of younger age, male gender and South Asian and Black ethnicity are particularly vulnerable to acute mental health conditions during lockdown. Patients with acute cases of anxiety have increased during lockdown whereas suicide and intentional drug overdose have decreased. CONCLUSIONS Self-reported data may underrepresent the true impact of lockdown on male mental health and ethnic minority groups. Emergency medical data can be used to identify vulnerable communities in the context of the extraordinary circumstances surrounding the current pandemic, as well as under more ordinary circumstances.

Abstract
Methadone overdoses are usually considered "slow" and avoidable deaths. Despite being frequently witnessed, the type and duration of the agonal time are rarely documented and challenging to be reconstructed. Here we report a case in which a young male was found dead in a parked car, shortly after discharge from a compulsory psychiatric treatment. Death scene investigation, clinical records collection, analysis of video recordings from surveillance cameras and private videos, post-mortem examination, GC-MS and LC-MS/MS toxicological analyses were performed and allowed to assess an acute fatal intoxication by methadone and prescription drugs. The case here-in reported is a rare example of a witnessed and recorded prolonged agonal phase due to methadone and drug intoxication, which lasted at least 12 hours. The loss of consciousness and a worsening pattern of respiratory depression, including gasping, were reported by the friends of the victim, but no one called for help, arising the suspect of failure to provide assistance. The possibility of a long-lasting agony with respiratory gasping should be considered in the evaluation of similar intoxication cases.

Abstract
INTRODUCTION It has remained controversial if antipsychotic treatment is associated with increased or decreased mortality among patients with schizophrenia, and if there are any clinically meaningful differences between specific agents and routes of administration. METHODS We linked prospectively gathered nationwide register-based data during 2006-2013 to study all-cause mortality among all patients aged 16-64years with schizophrenia in Sweden (N=29,823 in total; N=4603 in the incident cohort). Multivariate Cox regression models were adjusted for clinical and sociodemographic covariates. Sensitivity analyses with the incident cohort were conducted to control for survival bias. RESULTS During the mean follow-up of 5.7years, 2515 patients (8.4%) died. During the maximum follow-up (7.5years), the lowest cumulative mortality was observed for second generation (SG) long-acting injection (LAI) use (7.5%). Adjusted hazard ratios (aHRs) compared to SG LAI use were 1.37 (95%CI 1.01-1.86) for first generation (FG) LAIs, 1.52 (1.13-2.05) for SG orals, 1.83 (1.33-2.50) for FG orals, and 3.39 (2.53-4.56) for nonuse of antipsychotics. Concerning specific agents, the lowest mortality was observed for once-monthly paliperidone LAI (0.11, 0.03-0.43), oral aripiprazole (0.22, 0.15-0.34), and risperidone LAI (0.31, 0.23-0.43). In pairwise comparison, LAIs were associated with 33% lower mortality than equivalent orals (0.67, 0.56-0.80). The results with incident cohort were consistent with the primary analyses. CONCLUSIONS Among patients with schizophrenia, LAI use is associated with an approximately 30% lower risk of death compared with oral agents. SG LAIs and oral aripiprazole are associated with the lowest mortality.

Abstract
Psychiatric agents are among the most commonly prescribed medications. Despite the advent of newer generation agents, patients receiving them still experience cardiovascular (CV) side effects. However, these agents may have heterogeneous properties, calling for an individualized approach based on efficacy and also on the particular side effect profile of each specific agent. Proarrhythmic effects arising from drug-induced long-QT syndrome and consequent potentially life-threatening polymorphic ventricular arrhythmias in the form of torsade de pointes, the metabolic syndrome contributing to atherosclerosis and acute coronary syndromes, and drug-induced orthostatic hypotension raise major concerns. Of course, it is also crucial that fear of potential CV adverse effects does not deprive psychiatric patients of appropriate drug therapy. Modification of CV risk factors in psychiatric patients together with optimal management of their CV diseases and appropriate selection of psychotropic agents with greater efficacy and least CV toxicity are of paramount importance in mitigating CV risks and enhancing safety. Identifying patients at high risk of CV complications and close monitoring of all patients receiving these agents are crucial steps to prevent and manage such complications. All these issues are herein reviewed, relevant guidelines are discussed, and schemas are depicted that illustrate the interrelated connections among the psychotropic agents and their CV effects.

Abstract
There is much evidence from clinical trials that antidepressants help prevent relapse and recurrence of major depression. However, this is unlikely to hold true for all patients with depression, particularly those treated in primary care. Individual antidepressants are equally efficacious, so choice (as first-line treatment in general or for individual patients) is largely determined by differences in side-effects, even though many of these disappear during long-term treatment, owing to adaptation. Specific effects that are considered in choosing a drug include those on cognition, psychomotor performance and sexual function; drug interactions, lethality in overdose and the potential for teratogenicity are also considered. There are insufficient entirely objective and generally accepted data on pharmaco-economics to allow for confident recommendations on drug choice for long-term treatment. Drug acquisition costs must be considered by those with restricted budgets, and especially patients in developing countries where difference in cost between newer and older drugs can be translated into more food for a hungry family.

Abstract
In June last year, the committee on safety of medicines (CSM) advised against the use of paroxetine in depressed children and adolescents. This was subsequently followed by a similar warning regarding the use of other selective serotonin reuptake inhibitors (SSRIs), with the exception of fluoxetine (http://www.mhra.gov.uk/). The basis of this decision was a detailed review of both the published and the unpublished data. The latter were obtained from pharmaceutical companies who had not reported negative results from clinical trials to the medical community. The addition of the pharmaceutical industry data to published results exerted dramatic effects on the efficacy of available compounds. Thus with the exception of fluoxetine, the risks outweigh the benefits of the SSRIs in the treatment of childhood depression. In particular, there is evidence of a non-significant trend towards increased suicidality with most SSRIs compared with placebo. These findings have been supported by a further recent meta-analysis of the available published and unpublished data (Whittington et al, 2004). A review of the safety and efficacy of antidepressants in children and adolescents by Jureidini et al (2004) has also criticised the quality of reporting of the published trials. The review concluded that the benefits of SSRIs have been exaggerated, including those of fluoxetine, and the adverse effects have been downplayed. The authors suggest that psychological treatments are probably safer and more effective.

Abstract
The prevalence of coexisting substance misuse and psychiatric disorder (dual diagnosis, comorbidity) has increased over the past decade, and the indications are that it will continue to rise. There have simultaneously been unprecedented developments in the pharmacological treatment of alcohol, opiate and nicotine misuse. Here we evaluate the evidence on the use of some of these treatments in dual diagnosis (with psychotic, mood and anxiety disorders). The evidence base is limited by the exclusion of mental illness when pharmacological agents for substance misuse are evaluated and vice versa. We set the available information within the context of the psychosocial management of comorbid substance misuse and mental illness, and the framework for service delivery recommended by UK national policy.

Abstract
OBJECTIVE We aimed to evaluate the risk of ventricular arrhythmia (VA) and/or sudden cardiac death (SCD) associated with antidepressant use. METHODS A cohort study was conducted using data from Taiwan's National Health Insurance Research Database from 2001 to 2012. A total of 793,460 new antidepressant users with depressive disorders were enrolled in the study. Outcomes were defined as the first principal diagnosis of VA or SCD in the emergency department or hospital discharge records. Cox proportional hazards models with stratification of propensity score deciles were used to evaluate the relative risk of VA/SCD for antidepressants compared with selective serotonin reuptake inhibitors (SSRIs). RESULTS A total of 245 VA/SCD events occurred. The incidence rate of VA/SCD among antidepressant users was 1.5 per 1000 person-years (95% confidence interval [CI], 1.3-1.7). Compared with SSRIs, the risk of VA/SCD was significantly lower for tricyclic or tetracyclic antidepressant (TCAs) (adjusted hazards ratio [aHR], 0.54; 95% CI, 0.36-0.83), but not other antidepressant classes. However, use of moderate- to high-dose TCAs carried a higher risk than low-dose TCAs (aHR, 4.37; 95% CI, 1.23-15.60). Antidepressant polypharmacy was associated with an increased risk of VA/SCD (aHR, 1.63; 95% CI, 1.07-2.49). CONCLUSIONS There was no difference in VA/SCD risk across antidepressant classes except that TCAs were associated with a lower risk than SSRIs. However, the observed comparative risk of TCAs might be attributable to low-dose TCA use, which is quite common in current clinical practice. It would be of importance to carry out further investigations to scrutinize the influence of antidepressants on VA/SCD.

Bleeding risk under selective serotonin reuptake inhibitor (SSRI) antidepressants: A meta-analysis of observational studies. Pharmacol Res 2016; 118:19-32. [PMID: 27521835 DOI: 10.1016/j.phrs.2016.08.017] [Citation(s) in RCA: 85] [Impact Index Per Article: 10.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/01/2016] [Revised: 08/09/2016] [Accepted: 08/09/2016] [Indexed: 01/26/2023]
Abstract
Selective serotonin reuptake inhibitors (SSRIs) have been reported to be potentially associated with an increased risk of bleeding. A meta-analysis of observational studies was conducted to quantify this risk. Case-control and cohort studies investigating bleeding risk under SSRI therapy were retrieved by searching the Medline, Pascal, Google Scholar and Scopus databases. Case-control studies were included if they reported bleeding incidents with and without the use of SSRIs and cohort studies were included if they reported the rate of bleeds among SSRI users and non-users. The main outcome was severe bleeding, whatever the site. Only data concerning SSRI belonging to the ATC class N06AB were used. For both case-control and cohort studies, we recorded the adjusted effect estimates and their 95% confidence intervals (CI). Pooled adjusted odds ratio (OR) estimates were computed for case-control and cohort studies using an inverse-variance model. Meta-analysis of the adjusted ORs of 42 observational studies showed a significant association between SSRI use and the risk of bleeding [OR 1.41 (95% CI 1.27-1.57), random effect model, p<0.0001]. The association was found for the 31 case-control studies (1,255,073 patients), with an increased risk of 41% of bleeding [OR 1.41 (95% CI 1.25-1.60)], as well as for the 11 cohort studies including 187,956 patients [OR 1.36 (95% CI 1.12-1.64)]. Subgroup analyses showed that the association remained constant whatever the characteristics of studies. This meta-analysis shows an increased risk of bleeding of at least 36% (from 12% to 64%) based on the high-level of observational studies with SSRIs use.

Abstract
INTRODUCTION Venlafaxine is one of the most frequently prescribed antidepressants worldwide, despite its toxicity risk in overdose. Furthermore, the molecule has been recently identified at the EU-wide level as one of the novel psychoactive substances. This paper aims at investigating the potential of misuse, taking into account both the existing literature and the analysis of the misusers' experiences as described in venlafaxine misuse web reports. METHODS A literature search was performed using PubMed, Embase, and Medline. Posts/threads relating to venlafaxine misuse issues were identified through Google® and Yahoo® English-language searches. Resulting websites' data were then qualitatively assessed, and information was collected on a range of issues, including dosage, drug intake modalities, untoward drug effects, and association with other recreational drugs. RESULTS A few literature case reports focusing on venlafaxine as a misusing drug were here identified. The molecule was here typically ingested or snorted at dosages up to 10-15 times higher than those clinically advised, obtaining MDMA/amphetamine-like stimulant and psychedelic effects. Polydrug misuse was commonly reported. Venlafaxine appeared to be widely available online for sale. CONCLUSIONS Physicians should carefully evaluate patients for history of drug dependence and observe them for signs of venlafaxine misuse.

Abstract
BACKGROUND Sleep reduction or enhancement is frequently observed with second-generation antidepressant treatments, and they can be beneficial or harmful depending on the symptom profile of each subject. Nevertheless, relatively little attention has been given so far to rank those effects across compounds. The aim of this meta-analysis is to provide quantitative data about short-term rates of insomnia and somnolence associated with 14 second-generation antidepressants during the treatment of major depression. METHODS A literature search and a search of unpublished documents were performed. Eligible studies focusing on MD patients treated with second-generation antidepressants were entered in the analysis. Our primary outcome measures were insomnia and somnolence rates induced by antidepressants as compared with those associated with placebo. Sensitivity analyses were carried out as well. RESULTS Ten second-generation antidepressants showed higher rates of insomnia than placebo. The highest incidence was found for bupropion and desvenlafaxine. Agomelatine was the only antidepressant with a lower likelihood of inducing insomnia than placebo. Eleven antidepressants were associated with higher rates of somnolence than placebo. Fluvoxamine and mirtazapine showed the highest frequency of somnolence. Bupropion induced somnolence to a lower extent than placebo. Sensitivity analyses showed a degree of variation of those findings. DISCUSSION Antidepressants are associated with different insomnia and somnolence rates, mainly depending on their mechanisms of action. Despite some limitations, we underscore that the treatment-emergent insomnia and/or somnolence are frequent, and they could be used in clinical practice to face the specific needs of each patient.

Abstract
A revision of the 2008 British Association for Psychopharmacology evidence-based guidelines for treating depressive disorders with antidepressants was undertaken in order to incorporate new evidence and to update the recommendations where appropriate. A consensus meeting involving experts in depressive disorders and their management was held in September 2012. Key areas in treating depression were reviewed and the strength of evidence and clinical implications were considered. The guidelines were then revised after extensive feedback from participants and interested parties. A literature review is provided which identifies the quality of evidence upon which the recommendations are made. These guidelines cover the nature and detection of depressive disorders, acute treatment with antidepressant drugs, choice of drug versus alternative treatment, practical issues in prescribing and management, next-step treatment, relapse prevention, treatment of relapse and stopping treatment. Significant changes since the last guidelines were published in 2008 include the availability of new antidepressant treatment options, improved evidence supporting certain augmentation strategies (drug and non-drug), management of potential long-term side effects, updated guidance for prescribing in elderly and adolescent populations and updated guidance for optimal prescribing. Suggestions for future research priorities are also made.

Abstract
RATIONALE There is little clinical data available about seizure rates in psychiatric inpatients, and there are no studies with reference data to the frequencies of antidepressant (AD) use for this important clinical population. OBJECTIVE This study investigates seizure rates during AD treatment in psychiatric inpatient settings, drawn from the transnational pharmacovigilance programme Arzneimittelsicherheit in der Psychiatrie (AMSP) in relation to the known frequencies of ADs used in the participating clinics. Comparisons are made to former publications and their limitations. RESULTS Seventy-seven cases were identified with grand mal seizures (GMS) during AD treatment between 1993 and 2008, with a total number of 142,090 inpatients under surveillance treated with ADs in the participating hospitals. The calculated overall rate of reported seizures of patients during AD treatment in this collective is 0.05 % for ADs imputed alone or in combination with other psychotropic drug groups and 0.02 % when only ADs were given and held responsible for GMS. The patients receiving tri- or tetracyclic ADs (TCAs) had a 2-fold risk to develop a seizure as compared to the overall average rate in this sample. In 11 cases, there was only one AD imputed--the majority of these cases (9/11) were TCA. Monotherapy with selective serotonin reuptake inhibitors (SSRI) or dual serotonin and noradrenaline reuptake inhibitors (SNRI) were never imputed alone in this sample. CONCLUSIONS The results of the study favour the assumption that SSRIs, noradrenergic and specific serotonergic antidepressants (NaSSA) and dual SNRI might be more appropriate than TCAs for the treatment of psychiatric patients with an enhanced seizure risk.

Abstract
INTRODUCTION Evidence increasingly points to the potential development of harmful cardiac side effects concomitant with the use of a number of psychotropic drugs, primarily traditional antipsychotics and tricyclic antidepressants. AREAS COVERED The US Food and Drug Administration announced safety warnings associated with the use of citalopram with QT interval prolongation in 2011 and 2012. This paper explores the clinical background of QT interval prolongation, clinical data related to antidepressants and QT interval prolongation, the clinical implications of safety issues associated with the use of antidepressants and future research directions. EXPERT OPINION Currently available evidence proposes that citalopram may not be definitely associated with the increase of cardiac mortality, although it should be related with increase of QT prolongation. A firm consensus regarding the cardiac safety issues associated with antidepressants has to be established in near future. Hence, the choice of an individual antidepressant regarding cardiac safety issues should be based on multiple factors; clinicians may need to select the best available antidepressant for each individual based on that patient's vulnerability, the proven efficacy and safety of each agent and a reasonable benefit:risk ratio, based on currently available findings.

Abstract
CONTEXT Major depressive disorder (MDD) can be challenging to diagnose in patients with congestive heart failure, who often suffer from fatigue, insomnia, weight changes, and other neurovegetative symptoms that overlap with those of depression. Pathophysiologic mechanisms (eg, inflammation, autonomic nervous system dysfunction, cardiac arrhythmias, and altered platelet function) connect depression and congestive heart failure. OBJECTIVE We sought to review the prevalence, diagnosis, neurobiology, and treatment of depression associated with congestive heart failure. DATA SOURCES A search of all English-language articles between January 2003 and January 2013 was conducted using the search terms congestive heart failure and depression. STUDY SELECTION We found 1,498 article abstracts and 19 articles (meta-analyses, systematic reviews, and original research articles) that were selected for inclusion, as they contained information about our focus on diagnosis, treatment, and pathophysiology of depression associated with congestive heart failure. The search was augmented with manual review of reference lists of articles from the initial search. Articles selected for review were determined by author consensus. DATA EXTRACTION The prevalence, diagnosis, neurobiology, and treatment of depression associated with congestive heart failure were reviewed. Particular attention was paid to the safety, efficacy, and tolerability of antidepressant medications commonly used to treat depression and how their side-effect profiles impact the pathophysiology of congestive heart failure. Drug-drug interactions between antidepressant medications and medications used to treat congestive heart failure were examined. RESULTS MDD is highly prevalent in patients with congestive heart failure. Moreover, the prevalence and severity of depression correlate with the degree of cardiac dysfunction and development of congestive heart failure. Depression increases the risk of congestive heart failure, particularly in those patients with coronary artery disease , and is associated with a poorer quality of life, increased use of health care resources, more frequent adverse clinical events and hospitalizations, and twice the risk of mortality. CONCLUSIONS At present, limited empirical data exist with regard to treatment of depression in the increasingly large population of patients with congestive heart failure. Evidence reveals that both psychotherapeutic treatment (eg, cognitive-behavioral therapy) and pharmacologic treatment (eg, use of the selective serotonin reuptake inhibitor sertraline) are safe and effective in reducing depression severity in patients with cardiovascular disease. Collaborative care programs featuring interventions that work to improve adherence to medical and psychiatric treatments improve both cardiovascular disease and depression outcomes. Depression rating scales such as the 9-item Patient Health Questionnaire should be used to monitor therapeutic efficacy.

Abstract
PurposeThe purpose of this paper is to examine the prescribed psychotropic medications taken by newly referred people with a range of substance use disorders (SUD) who attend a specialist community addiction service.Design/methodology/approachAnonymised data on newly referred people (n=1,537) with SUD attending a specialist community addiction service for their first episode of treatment between August 2007 and July 2010 were obtained from the database of the service. Data were cleaned and the percentage of people taking prescribed psychotropic medications at their first episode of treatment was calculated.FindingsMore than half (56.1 percent) of people attending the service were taking prescribed antidepressants and anxiolytics at their first episode of treatment whilst 15.2 percent of people were taking prescribed antipsychotics. Alcohol and opioids were the primary referral substances for 77.4 percent and 15.2 percent of people respectively. People referred for “other” substances (cannabis, stimulants, sedatives, hallucinogens, solvents and polydrug use) made up the remaining 7.5 percent and had the highest percentage of prescribed psychotropics (antipsychotics=47 percent, antidepressants and anxiolytics=64.3 percent) compared to those referred for alcohol and opioids (p<0.0005).Originality/valueTo the best of the authors’ knowledge, this is the first study of psychotropic prescribing among people with a range of SUD in the UK. The high prevalence of psychotropic prescribing raises questions about the appropriateness of these prescriptions and calls for scrutiny of prescribing practice in this group of people.

Abstract
Among the antidepressants, the selective serotonin reuptake inhibitors (SSRIs) are often preferred to other classes of antidepressants in the treatment of depression in the elderly because of their better safety profile. Most of the known effects of SSRIs, either beneficial or adverse, are linked to their inhibitory action on the serotonin reuptake transporter (5-HTT). This reuptake mechanism is present not only in neurons but also in other cells such as platelets. Serotoninergic mechanisms seem to play an important role in haemostasis, and their importance in this regard has long been underestimated. Abnormal activation may lead to a pro-thrombotic state, as may occur in patients with major depressive disorder, whilst downregulation, as occurs in patients treated with SSRIs, may have two clinical consequences, both of particular interest in the elderly. On the one hand, there may be an increased risk of bleeding; on the other hand, a reduction in thrombotic risk may be possible. Polymorphism in the promoter region of the gene that transcribes the 5-HTT has been shown to have a relevant impact on its function and, in turn, on the beneficial and adverse effects of SSRIs. Bleeding has been a concern since the introduction of SSRIs, with multiple case reports published and communicated to the pharmacovigilance systems. The first epidemiological study was published in 1999 and since then, 34 epidemiological studies from different areas, most of them including elderly patients in their study populations, have been published with a variety of results. Broadly, the epidemiological evidence supports a moderately increased risk of bleeding associated with the use of SSRIs, which may be critically dependent on patient susceptibility and the presence of risk factors. The impairment of primary haemostasis induced by SSRIs may result, as a beneficial counterpart, in a reduction in the thrombotic risk. A small number of clinical trials and an increasing number of epidemiological studies that include elderly patients have been conducted to clarify whether SSRIs reduce the risk of primary and secondary ischaemic disorders. However, the results have been inconclusive with some studies suggesting a preventive effect and others no effect or even an increased risk. Behind such contradictory results may be the role of depression itself as a cardiovascular risk factor and, therefore, a major confounding factor. How to disentangle its effect from that of the antidepressants is the methodological challenge to be overcome in future studies. In this complex scenario, the elderly seem to be at a crossroads, because they are the group in which both the risks and the benefits can be the greatest. Studies performed to date have provided us with some clues that can help orient clinicians in taking the most appropriate course of action. For instance, as the gastrointestinal bleeding risk appears to increase with age, prudent advice in patients with a previous history of upper-gastrointestinal bleeding or peptic ulcer, and in those who take NSAIDs, oral anticoagulants, antiplatelet drugs or corticosteroids, would be to suggest addition of an acid-suppressing agent to the drug regimen in those elderly patients in whom SSRIs are indicated.

Prog Neuropsychopharmacol Biol Psychiatry 2011; 35:1279-83.

Abstract
BACKGROUND Substance-related deaths account for a great number of suicides. AIM To investigate levels and characteristics of suicide verdicts, as opposed to accidental deaths, in substance misusers. METHODS Psychological autopsy study of cases from the UK National Programme on Substance Abuse Deaths (np-SAD) during the period 2001-2007. RESULTS Between January 2001 and December 2007, 2108 suicides were reported to the np-SAD. Typical suicide victims were White and older than 50 (respectively 95% and 41% of cases). Medications, especially antidepressants (44%), were prescribed to 87% of victims. Significantly fewer suicide victims than controls presented positive blood toxicological results for illicit drugs (namely: cocaine, heroin, amphetamines, ecstasy-type drugs, cannabis, and GHB/GBL) and alcohol. CONCLUSIONS Suicide prevention programmes should devote specific attention to deaths among substance misusers who are at high risk of fatal intentional self-harm. Specific characteristics distinguish those at risk; caregivers should be better educated as to what these factors are. Limitations of the current study included lack of provision of comprehensive information relating to the victims' psychosocial variables. Furthermore, no differentiation between different classes of antidepressants in terms of involvement in suicide was here provided.

Abstract
Background There is a lack of international research on suicide by drug overdose as a preventable suicide method. Sex- and age-specific rates of suicide by drug self-poisoning (ICD-10, X60-64) and the distribution of drug types used in 16 European countries were studied, and compared with other self-poisoning methods (X65-69) and intentional self-injury (X70-84). Methods Data for 2000-04/05 were collected from national statistical offices. Age-adjusted suicide rates, and age and sex distributions, were calculated. Results No pronounced sex differences in drug self-poisoning rates were found, either in the aggregate data (males 1.6 and females 1.5 per 100,000) or within individual countries. Among the 16 countries, the range (from some 0.3 in Portugal to 5.0 in Finland) was wide. 'Other and unspecified drugs' (X64) were recorded most frequently, with a range of 0.2-1.9, and accounted for more than 70% of deaths by drug overdose in France, Luxembourg, Portugal and Spain. Psychotropic drugs (X61) ranked second. The X63 category ('other drugs acting on the autonomic nervous system') was least frequently used. Finland showed low X64 and high X61 figures, Scotland had high levels of X62 ('narcotics and hallucinogens, not elsewhere classified') for both sexes, while England exceeded other countries in category X60. Risk was highest among the middle-aged everywhere except in Switzerland, where the elderly were most at risk. Conclusions Suicide by drug overdose is preventable. Intentional self-poisoning with drugs kills as many males as females. The considerable differences in patterns of self-poisoning found in the various European countries are relevant to national efforts to improve diagnostics of suicide and appropriate specific prevention. The fact that vast majority of drug-overdose suicides came under the category X64 refers to the need of more detailed ICD coding system for overdose suicides is needed to permit better design of suicide-prevention strategies at national level.

Abstract
BACKGROUND Selective serotonin reuptake inhibitors (SSRIs) are the most widely used antidepressants in the world. Recent studies, however, have raised the concern that SSRIs increase the risk of gastrointestinal dysfunction. Therefore, we conducted a case-control study on gastrointestinal symptoms and endoscopic findings in patients who were taking SSRIs in Japan. METHODS Forty-one patients who were taking SSRIs (SSRI-treated group) and 82 age- and sex-matched patients who were not taking antidepressants (control group) were selected from the population of patients who underwent endoscopic examination from January 1, 2005 to March 31, 2010 in our institution, and their subjective symptoms and endoscopic findings were analyzed. Patients who were taking proton pump inhibitors (PPIs) and/or histamine H(2)-receptor antagonists (H2RAs) were excluded from this study. RESULTS The chief complaints at the endoscopic examination were classified into the following 4 categories: reflux symptoms, dysmotility symptoms, ulcer-like symptoms, and no upper abdominal symptoms. No significant difference was found in the complaint rate of each category between the SSRI-treated and the control groups. No significant differences were found between the groups in endoscopic findings, the LANZA score and the rate of chief complaints in patient classes stratified by the endoscopic finding. CONCLUSION It was not evident that SSRIs induced mucosal damage of the upper gastrointestinal tract. And, it is considered that SSRIs do not increase the risk of upper gastrointestinal symptoms in patients treated with SSRIs for 1 month or longer. The present study suggests that SSRI medication does not have a bad influence on gastrointestinal symptoms and gastrointestinal organic diseases.

Abstract
To compare the clinical features of deliberate self-poisoning with venlafaxine and selective serotonin reuptake inhibitors (SSRIs) presenting to the emergency department of an Australian tertiary referral hospital. A retrospective cohort study comparing all 36 patients who presented with venlafaxine self-poisoning with 44 randomly selected patients with SSRI self-poisoning between 1997 and 2006. Patients who had overdosed on venlafaxine were older (mean age 37.4 versus 28.8 years, p ≤ 0.001) and generally exhibited a higher degree of suicidal intent (p ≤ 0.017). Median venlafaxine dose taken was 35 defined daily doses (DDDs) compared with SSRIs 19.4 DDDs. Those who ingested venlafaxine were more likely to become confused (25% versus 0%; p = 0) and have mydriasis (19.4% versus 2%; p ≤ 0.02), than those who took SSRIs. One patient from the venlafaxine group died. Compared with SSRI self-poisoners, patients who deliberately ingested venlafaxine were more likely to exhibit serious suicide intent. They were also more likely to be older, take a higher DDD of the drug, and have confusion and mydriasis. This has implications for management of severely depressed and suicidal patients.

Abstract
Tricyclic antidepressants (TCAs) are among the most effective antidepressants available, although their poor tolerance at usual recommended doses and toxicity in overdose make them difficult to use. While selective serotonin reuptake inhibitors (SSRIs) are better tolerated than TCAs, they have their own specific problems, such as the aggravation of sexual dysfunction, interaction with coadministered drugs, and for many, a discontinuation syndrome. In addition, some of them appear to be less effective than TCAs in more severely depressed patients. Increasing evidence of the importance of norepinephrine in the etiology of depression has led to the development of a new generation of antidepressants, the serotonin and norepinephrine reuptake inhibitors (SNRIs). Milnacipran, one of the pioneer SNRIs, was designed from theoretic considerations to be more effective than SSRIs and better tolerated than TCAs, and with a simple pharmacokinetic profile. Milnacipran has the most balanced potency ratio for reuptake inhibition of the two neurotransmitters compared with other SNRIs (1:1.6 for milnacipran, 1:10 for duloxetine, and 1:30 for venlafaxine), and in some studies milnacipran has been shown to inhibit norepinephrine uptake with greater potency than serotonin (2.2:1). Clinical studies have shown that milnacipran has efficacy comparable with the TCAs and is superior to SSRIs in severe depression. In addition, milnacipran is well tolerated, with a low potential for pharmacokinetic drug-drug interactions. Milnacipran is a first-line therapy suitable for most depressed patients. It is frequently successful when other treatments fail for reasons of efficacy or tolerability.

Abstract
This article aims to highlight current trends in the pharmacologic management of obsessive-compulsive disorder (OCD). A systematic search of the electronic database MEDLINE was conducted. The first case report of clomipramine efficacy in the management OCD more than 40 years ago gave new hope for the treatment of this debilitating disorder. Selective serotonin reuptake inhibitors (SSRIs) proved to have a similar efficacy profile compared with clomipramine but had a superior tolerability profile. While many patients with OCD respond to SSRIs or clomipramine, the treatment of those with refractory OCD remains challenging. Different augmentation agents in treatment-resistant OCD have been explored, with antipsychotic agents having the largest supporting evidence base. Nevertheless, new pharmacologic treatment options are required and are under investigation.

Abstract
Venlafaxine (VEN) is an antidepressant found to possess a higher fatal toxicity index (FTI, i.e., deaths in proportion to consumption) than other newer antidepressants and selective serotonin reuptake inhibitors (SSRIs). The aim of this study was to elucidate using post-mortem cases whether the apparent high toxicity of VEN is associated with adverse drug interactions, pharmacogenetic factors and/or the manner of death. Within a 2-year period, a comprehensive post-mortem database and death certificates were searched for cases with laboratory findings of VEN, findings of other drugs, associated background information and the cause and manner of death. In 123 cases, the concentrations of VEN and its two metabolites, O-desmethylvenlafaxine (O-VEN) and N-desmethylvenlafaxine (N-VEN), and the CYP2D6 genotype were determined in post-mortem blood. The median concentrations of VEN, O-VEN and N-VEN were 560, 420 and 49 µg/l, respectively. A prominent feature of the VEN-positive cases was the high abundance of interacting drugs (46%), being more common with higher VEN concentrations. Compared to other common antidepressants, VEN-positive cases showed the highest suicide frequency, but also the proportion of suicidal VEN poisonings of all suicides was substantially higher than that of mirtazapine or SSRIs. Relative CYP2D6 activity did not predispose to high VEN concentrations, and the frequency of the extreme phenotypes followed the general population. In conclusion, the high suicide potential of VEN in combination with the high prevalence of drugs causing adverse interactions could be the reason for the observed high FTI.

Abstract
Depression is one of the most commonly encountered conditions in women's health, but many providers lack the knowledge and skills needed to identify and manage depression in primary care settings. This article discusses strategies that can improve the identification and treatment of depression. In addition, it describes how these strategies were incorporated into an urban inner-city health center. These strategies used in this setting can be adapted for use in either comprehensive health care centers or in practices providing primarily obstetric and gynecologic services.

Abstract
Depression is a common illness with a large clinical phenotype, and clinicians have numerous guidelines to treat this disorder : many antidepressant drugs are available with different pharmacological profiles and stepped strategies are proposed to obtain a remission. It exists a relationship between baseline depression symptom severity and treatment response and patient with higher levels of severity received significantly more intervention visits, more months of antidepressant treatment and more antidepressant trials, but there is not accepted and consensual definition for severe depression. By using cut-off scores on rating scales severe depression is at one extreme of a continuum of severity (but scales which serve for quantifying the intensity of the depression with thresholds present an interest and also limits, in the current practice, they are rarely used), in the other hand some symptoms contributes to severity (psychotics features, suicidal ideation), evolution and prognosis is a part of severity too (recurrences, chronicity), severe depression can influence a somatic pathology contributing to severity (could be considered itself as a major risk factor) and have an impact on treatment outcome, finally by its role on morbi-mortality and handicap, depression is often a severe disorder. So, concerning the therapeutic choices, there are few data to choose specific options because the concept of severity in the depression is not still clearly defined in studies and few randomized contolled studies have been done in this indication and adapted to different modality of the severity expression. Symptom-free remission is a goal for treatment in severe depression, but complications have to be considered in medication algorithms. In this paper, we review the modalities of prescription of antidepressants according to these differences of the severity in depression.

Abstract
OBJECTIVE To assess whether use of the antidepressant venlafaxine is associated with an increased risk of sudden cardiac death or near death compared with other commonly used antidepressants. DESIGN Population based observational study. SETTING We did a nested case-control analysis within a new user cohort formed using the United Kingdom General Practice Research Database. PARTICIPANTS New users of venlafaxine, fluoxetine, citalopram, or dosulepin on or after 1 January 1995, aged 18 to 89 years, with a diagnosis of depression or anxiety. Participants were followed-up until February 2005, or the occurrence of sudden cardiac death or near death, identified from medical records indicating non-fatal acute ventricular tachyarrhythmia, sudden death due to cardiac causes, or out of hospital deaths from acute ischaemic cardiac events. For each case, 30 controls were selected matched for age, sex, calendar time, and indication. We used conditional logistic regression to calculate the adjusted odds ratio of sudden cardiac death or near death associated with current use of venlafaxine compared with current use of fluoxetine, citalopram or dosulepin. RESULTS 207 384 participants were followed-up for an average of 3.3 years. There were 568 cases of sudden cardiac death or near death, which were matched to 14 812 controls. The adjusted odds ratio of sudden cardiac death or near death associated with venlafaxine use was 0.66 (95% confidence interval 0.38 to 1.14) relative to fluoxetine use, whereas compared with citalopram it was 0.89 (0.50 to 1.60) and with dosulepin 0.83 (0.46 to 1.52). CONCLUSIONS In this large, population based study, the use of venlafaxine was not associated with an excess risk of sudden cardiac death or near death compared with fluoxetine, dosulepin, or citalopram, in patients with depression or anxiety.

Abstract
BACKGROUND AND AIMS self-poisoning accounts for a substantial proportion of acute medical hospital presentations, but has been poorly characterised in older adults. This study sought to determine the agents ingested by older adults presenting to hospital after drug overdose, and to compare clinical outcomes to younger patients. METHODS a retrospective observational study of patients admitted via the emergency department due to drug overdose between 2004 and 2007. RESULTS during the study period, there were 8,059 admissions, including 4,632 women (57.5%). This included a subgroup of 361 patients (4.5%) who were >60 years of age. This subgroup was more likely to require hospital stay >1 night, odds ratio (95% confidence interval) = 4.3 (3.6-5.5, P < 0.0001), transfer to a critical care area = 3.8 (1.1-13.0, P = 0.0340) and had higher mortality = 4.8 (1.1-22.1, P = 0.0463). A higher proportion of older patients required transfer to a psychiatric unit (P < 0.0001) or to a general medical ward (P < 0.0001) than younger adults. CONCLUSIONS older adults that presented to hospital after drug overdose had ingested different drugs than younger patients, possibly due to different prescribing patterns, and had a poorer outcome. The use of drugs associated with significant toxicity should be avoided in older patients at risk of self-harm.

Abstract
Objectives: To compare the efficacy and pharmacologic, pharmacokinetic, drug interaction and adverse effect profiles of duloxetine and venlafaxine. Methods: A systematic review of the literature pertaining to duloxetine and venlafaxine was conducted using a computer-aided search of MEDLINE and EMBASE for the period January 1988 to May 2008 with the following search terms: venlafaxine and duloxetine and depression, clinical studies, pharmacology, drug interactions, pharmacokinetics, adverse effects, safety, case reports and review articles. Results: Duloxetine and venlafaxine have comparable efficacy and share similar pharmacologic profiles but differ somewhat in their pharmacokinetic profiles, drug interactions and adverse effects. Both agents block the reuptake of serotonin and norepinephrine and both are substrates for the cytochrome P450 2D6 isoenzyme; however, duloxetine inhibits these enzymes to a moderate extent, whereas venlafaxine is only a weak inhibitor. Furthermore, duloxetine is more extensively bound to protein than venlafaxine. Venlafaxine is more likely to elevate blood pressure in a dose-related manner. Both duloxetine and venlafaxine have the potential to cause hepatic injury. Conclusions: Although venlafaxine and duloxetine have similar efficacy in the treatment of depression, differences in their adverse effects and pharmacokinetic profiles suggest that one agent may be preferred over the other in certain patient groups.

Abstract
Sertraline is a selective serotonin reuptake inhibitor that has been used and studied extensively throughout the world and found to be safe and well tolerated in numerous patient populations, including those with either psychiatric and/or medical comorbidities. Randomized clinical trials have shown that it is an effective treatment for depressive and anxiety disorders and its efficacy is unaffected by psychiatric comorbidity. In non-comorbid patients, sertraline is effective for the acute treatment of major depressive disorders and prevention of relapse or recurrence. It is effective for acute treatment and longer-term management of social anxiety disorder, posttraumatic stress disorder,panic disorder, and generalized anxiety disorder. In adults and in pediatric patients, it is an effective short-term and long-term treatment for obsessive compulsive disorder.Sertraline has a good tolerability profile and has low fatal toxicity. In summary, sertraline is as effective as other antidepressants over a wide range of indications but may offer tolerability benefits as well as efficacy in patients with psychiatric and/or medical comorbidities and certain subtypes of depression.

Abstract
OBJECTIVE To review data examining the relationships between depression, antidepressants and cardiovascular disease. METHOD Structured searches of PubMed, Medline and Embase conducted in March 2008. RESULTS Depression and cardiovascular disease are closely associated clinical entities. Depression appears both to cause and worsen cardiovascular disease. Cardiovascular disease is in turn associated with a high incidence of depression. Depression is associated with increased mortality in cardiovascular disease, and after myocardial infarction (MI) and stroke. Many antidepressants have cardiotoxic properties. Tricyclic drugs are highly cardiotoxic in overdose and may induce cardiovascular disease and worsen outcome in established cardiovascular disease. Reboxetine, duloxetine and venlafaxine are known to increase blood pressure. Other antidepressants have neutral or beneficial effects in various cardiovascular disorders. CONCLUSION Sertraline, fluoxetine, citalopram, bupropion and mirtazapine appear to be safe to use after MI; the use of sertraline, and response to citalopram and mirtazapine may improve mortality. Paroxetine and citalopram appear to be safe to use in patients with established coronary artery disease. Limited data suggest that a variety of antidepressants are effective and safe to use after stroke.

Abstract
In the past few years several papers have reported critically on the risk of suicidal thoughts and behaviour associated with antidepressants, primarily SSRIs. The risk-benefit ratio of antidepressant (AD) treatment has been questioned especially in children and adolescents. The critical publications led to warnings being issued by regulatory authorities such as the FDA, MHRA and EMEA and stimulated new research activity in this field. However, potential harmful effects of antidepressants on suicidality are difficult to investigate in empirical studies because these have several methodological limitations. Randomised controlled trials (RCTs) are the most reliable way to test the hypothesis that AD have such side effects. In addition to meta-analyses of RCTs, complementary research methods should be applied to obtain the most comprehensive information. We undertook a comprehensive review of publications related to the topics ADs, suicide, suicidality, suicidal behaviour and aggression. Based on this comprehensive review we conclude that ADs, including SSRIs, carry a small risk of inducing suicidal thoughts and suicide attempts, in age groups below 25 years, the risk reducing further at the age of about 30-40 years. This risk has to be balanced against the well-known beneficial effects of ADs on depressive and other symptoms (anxiety, panic, obsessive-compulsive symptoms), including suicidality and suicidal behaviour. According to the principles of good clinical practice, decision making should consider carefully the beneficial effects of AD treatment as well as potentially harmful effects and attempt to keep the potential risks of AD treatment to a minimum. It is the major problem facing efforts to identify the possible 'suicidal effects' of antidepressants.

Abstract
The prevalence of important adverse drug combinations was studied among the 37,367 cases included in the Finnish post-mortem toxicology database during 2000-2006. The new SFINX interaction database (Swedish, Finnish, INteraction X-referencing) was utilised to identify adverse drug combinations. Consequently, the 24 drugs chosen for the study generated 96 two-compound combinations possessing potentially severe interactions. The total number of hits for the combinations found in the post-mortem database was 267, which accounts for approximately 0.71% of all cases. The potential role of adverse drug interaction (ADI) in these cases was evaluated from the background information and death certificate. The possible ADI cases comprised 23% of all hits and 0.17% of all cases analysed. In cases with a pharmacodynamic mechanism, the most prominent combinations were medicines causing serotonin syndrome or a beta(1)-blocker with verapamil or diltiazem. In cases with a pharmacokinetic mechanism, half of the cases involved digoxin in combination with verapamil. In one third of the possible ADI cases, a forensic pathologist had noted the studied compounds as an underlying or contributing cause of death, although the agents' specific role in ADIs was rarely recognised.

Abstract
A revision of the 2000 British Association for Psychopharmacology evidence-based guidelines for treating depressive disorders with antidepressants was undertaken to incorporate new evidence and to update the recommendations where appropriate. A consensus meeting involving experts in depressive disorders and their management was held in May 2006. Key areas in treating depression were reviewed, and the strength of evidence and clinical implications were considered. The guidelines were drawn up after extensive feedback from participants and interested parties. A literature review is provided, which identifies the quality of evidence to inform the recommendations, the strength of which are based on the level of evidence. These guidelines cover the nature and detection of depressive disorders, acute treatment with antidepressant drugs, choice of drug versus alternative treatment, practical issues in prescribing and management, next-step treatment, relapse prevention, treatment of relapse, and stopping treatment.

A randomized, double-blind comparison of duloxetine and venlafaxine in the treatment of patients with major depressive disorder. J Psychiatr Res 2008; 42:22-34.

Abstract
BACKGROUND Clinical trials assessing antidepressant therapies typically include separate assessments of efficacy (benefit) and adverse events (risk). Global benefit-risk (GBR) assessment allows the simultaneous evaluation of both efficacy and adverse events. The objective was to compare the serotonin and norepinephrine reuptake inhibitors (SNRIs) duloxetine and venlafaxine using GBR assessment. METHODS Data were combined from two similarly designed, multicenter, randomized, double-blind, parallel group studies in which patients with major depressive disorder were randomized to either duloxetine 60 mg/day or venlafaxine extended release (XR) 150 mg/day (75 mg/day for the first 2 weeks) for a 6-week fixed dosing period followed by an additional 6 weeks of treatment in which the dose could be increased up to 120 mg/day for duloxetine and 225 mg/day for venlafaxine. Patients completing the study (or receiving study drug for 2 weeks or more) were eligible to enter a taper period where the dose of study drug was gradually reduced over 1-2 weeks prior to drug discontinuation. The primary outcome measure (defined a priori) was the GBR comparison of duloxetine 60 mg/day and venlafaxine XR 150 mg/day after 6 weeks of treatment. In the GBR analysis, benefit was defined as remission at endpoint [17-item Hamilton Depression Rating Scale (HAMD17) 7]. Risk was defined by four categories: patients having either no adverse events (AEs), AEs with no severity rating greater than moderate, AEs with at least one severity rating of severe, or having discontinued with a reason of self-reported adverse event (regardless of any AE severity). Additional efficacy measures included HAMD17 total score and subscales, HAMA, CGI-S, and PGI-I. Safety and tolerability were assessed via analysis of reasons for discontinuation, treatment-emergent adverse events (TEAEs), discontinuation-emergent adverse events, and changes in vital signs, weight, and laboratory analytes. RESULTS There were no significant differences between duloxetine 60 mg/day and venlafaxine 150 mg/day as measured by GBR assessment at the end of 6 weeks (-1.418 vs. -1.079, P = 0.217) or 12 weeks (-0.349 vs. -0.121, P = 0.440), nor were there significant differences between treatment groups on the majority of efficacy measures. Significantly more venlafaxine-treated patients (74.5%) completed 12 weeks of treatment compared with duloxetine-treated patients (64.8%, P =.006). Nausea was the most common treatment-emergent adverse event (TEAE) for both drugs, and was significantly higher with duloxetine 60 mg/day compared to venlafaxine 150 mg/day during the first 6 weeks of treatment (43.6% vs. 35.0%, P0.05). During the taper period, significantly more venlafaxine-treated patients reported discontinuation-emergent adverse events (DEAEs) than duloxetine-treated patients. From a safety perspective, significantly more venlafaxine-treated patients (n = 4) than duloxetine-treated patients (n=0, P =.047) experienced sustained elevations of systolic blood pressure during the fixed dosing period. Otherwise, there were few significant differences in safety measures found between treatment groups during 6 and 12 weeks of therapy. CONCLUSIONS Duloxetine 60 mg/day and venlafaxine XR 150 mg/day have similar benefit-risk profiles on the basis of a comparison utilizing GBR assessment. The implications of the more subtle differences between these drugs, as well as for interpreting the GBR assessment, are discussed.
