Abstract
INTRODUCTION Major depressive disorder remains a major challenge due to its biopsychosocial burden with increased morbidity and mortality. Despite successful treatment options for the acute episode, recurrence rates are high, on average four times in a life span. AREAS COVERED Both pharmacological as non-pharmacological evidence-based therapeutic options to prevent and treat recurrent depression are discussed. EXPERT OPINION Although some risk factors for recurrence are well known, better evidence is needed. Antidepressant medication should be continued after acute treatment at its full therapeutic dose for longer periods, at least 1 year. There are no clear differences between classes of antidepressant medication when treatment is focused on preventing relapse. Bupropion is the only antidepressant with a proven efficacy to prevent recurrence in seasonal affective disorder. Recent findings conclude maintenance subanesthetic ketamine and esketamine treatment can be effective in sustaining antidepressant effect following remission. Furthermore, the pharmacological approach must be integrated with lifestyle interventions, especially aerobic exercise. Finally, combining pharma- and psychotherapy seems to improve outcome. Network and complexity sciences will help to decrease the high recurrence rates of MDD by developing more integrative and personalized approaches.

Abstract
BACKGROUND Depression and anxiety are the most frequent indication for which antidepressants are prescribed. Long-term antidepressant use is driving much of the internationally observed rise in antidepressant consumption. Surveys of antidepressant users suggest that 30% to 50% of long-term antidepressant prescriptions had no evidence-based indication. Unnecessary use of antidepressants puts people at risk of adverse events. However, high-certainty evidence is lacking regarding the effectiveness and safety of approaches to discontinuing long-term antidepressants. OBJECTIVES To assess the effectiveness and safety of approaches for discontinuation versus continuation of long-term antidepressant use for depressive and anxiety disorders in adults. SEARCH METHODS We searched all databases for randomised controlled trials (RCTs) until January 2020. SELECTION CRITERIA We included RCTs comparing approaches to discontinuation with continuation of antidepressants (or usual care) for people with depression or anxiety who are prescribed antidepressants for at least six months. Interventions included discontinuation alone (abrupt or taper), discontinuation with psychological therapy support, and discontinuation with minimal intervention. Primary outcomes were successful discontinuation rate, relapse (as defined by authors of the original study), withdrawal symptoms, and adverse events. Secondary outcomes were depressive symptoms, anxiety symptoms, quality of life, social and occupational functioning, and severity of illness. DATA COLLECTION AND ANALYSIS We used standard methodological procedures as expected by Cochrane. MAIN RESULTS We included 33 studies involving 4995 participants. Nearly all studies were conducted in a specialist mental healthcare service and included participants with recurrent depression (i.e. two or more episodes of depression prior to discontinuation). All included trials were at high risk of bias. The main limitation of the review is bias due to confounding withdrawal symptoms with symptoms of relapse of depression. Withdrawal symptoms (such as low mood, dizziness) may have an effect on almost every outcome including adverse events, quality of life, social functioning, and severity of illness. Abrupt discontinuation Thirteen studies reported abrupt discontinuation of antidepressant. Very low-certainty evidence suggests that abrupt discontinuation without psychological support may increase risk of relapse (hazard ratio (HR) 2.09, 95% confidence interval (CI) 1.59 to 2.74; 1373 participants, 10 studies) and there is insufficient evidence of its effect on adverse events (odds ratio (OR) 1.11, 95% CI 0.62 to 1.99; 1012 participants, 7 studies; I² = 37%) compared to continuation of antidepressants, without specific assessment of withdrawal symptoms. Evidence about the effects of abrupt discontinuation on withdrawal symptoms (1 study) is very uncertain. None of these studies included successful discontinuation rate as a primary endpoint. Discontinuation by "taper" Eighteen studies examined discontinuation by "tapering" (one week or longer). Most tapering regimens lasted four weeks or less. Very low-certainty evidence suggests that "tapered" discontinuation may lead to higher risk of relapse (HR 2.97, 95% CI 2.24 to 3.93; 1546 participants, 13 studies) with no or little difference in adverse events (OR 1.06, 95% CI 0.82 to 1.38; 1479 participants, 7 studies; I² = 0%) compared to continuation of antidepressants, without specific assessment of withdrawal symptoms. Evidence about the effects of discontinuation on withdrawal symptoms (1 study) is very uncertain. Discontinuation with psychological support Four studies reported discontinuation with psychological support. Very low-certainty evidence suggests that initiation of preventive cognitive therapy (PCT), or MBCT, combined with "tapering" may result in successful discontinuation rates of 40% to 75% in the discontinuation group (690 participants, 3 studies). Data from control groups in these studies were requested but are not yet available. Low-certainty evidence suggests that discontinuation combined with psychological intervention may result in no or little effect on relapse (HR 0.89, 95% CI 0.66 to 1.19; 690 participants, 3 studies) compared to continuation of antidepressants. Withdrawal symptoms were not measured. Pooling data on adverse events was not possible due to insufficient information (3 studies). Discontinuation with minimal intervention Low-certainty evidence from one study suggests that a letter to the general practitioner (GP) to review antidepressant treatment may result in no or little effect on successful discontinuation rate compared to usual care (6% versus 8%; 146 participants, 1 study) or on relapse (relapse rate 26% vs 13%; 146 participants, 1 study). No data on withdrawal symptoms nor adverse events were provided. None of the studies used low-intensity psychological interventions such as online support or a changed pharmaceutical formulation that allows tapering with low doses over several months. Insufficient data were available for the majority of people taking antidepressants in the community (i.e. those with only one or no prior episode of depression), for people aged 65 years and older, and for people taking antidepressants for anxiety. AUTHORS' CONCLUSIONS Currently, relatively few studies have focused on approaches to discontinuation of long-term antidepressants. We cannot make any firm conclusions about effects and safety of the approaches studied to date. The true effect and safety are likely to be substantially different from the data presented due to assessment of relapse of depression that is confounded by withdrawal symptoms. All other outcomes are confounded with withdrawal symptoms. Most tapering regimens were limited to four weeks or less. In the studies with rapid tapering schemes the risk of withdrawal symptoms may be similar to studies using abrupt discontinuation which may influence the effectiveness of the interventions. Nearly all data come from people with recurrent depression. There is an urgent need for trials that adequately address withdrawal confounding bias, and carefully distinguish relapse from withdrawal symptoms. Future studies should report key outcomes such as successful discontinuation rate and should include populations with one or no prior depression episodes in primary care, older people, and people taking antidepressants for anxiety and use tapering schemes longer than 4 weeks.

Abstract
BACKGROUND Findings of substantial remaining morbidity in treated major depressive disorder (MDD) led us to review controlled trials of treatments aimed at preventing early relapses or later recurrences in adults diagnosed with MDD to summarize available data and to guide further research. METHODS Reports (n = 97) were identified through systematic, computerized literature searching up to February 2015. Treatment versus control outcomes were summarized by random-effects meta-analyses. RESULTS In 45 reports of 72 trials (n = 14 450 subjects) lasting 33.4 weeks, antidepressants were more effective than placebos in preventing relapses (response rates [RR] = 1.90, confidence interval [CI]: 1.73-2.08; NNT = 4.4; p < 0.0001). In 35 reports of 37 trials (n = 7253) lasting 27.0 months, antidepressants were effective in preventing recurrences (RR = 2.03, CI 1.80-2.28; NNT = 3.8; p < 0.0001), with minor differences among drug types. In 17 reports of 22 trials (n = 1 969) lasting 23.7 months, psychosocial interventions yielded inconsistent or inconclusive results. CONCLUSIONS Despite evidence of the efficacy of drug treatment compared to placebos or other controls, the findings further underscore the substantial, unresolved morbidity in treated MDD patients and strongly encourage further evaluations of specific, improved individual and combination therapies (pharmacological and psychological) conducted over longer times, as well as identifying clinical predictors of positive or unfavorable responses and of intolerability of long-term treatments in MDD.

Abstract
These guidelines for the treatment of unipolar depressive disorders systematically review available evidence pertaining to the biological treatment of patients with major depression and produce a series of practice recommendations that are clinically and scientifically meaningful based on the available evidence. These guidelines are intended for use by all physicians assessing and treating patients with these conditions. The relevant data have been extracted primarily from various treatment guidelines and panels for depressive disorders, as well as from meta-analyses/reviews on the efficacy of antidepressant medications and other biological treatment interventions identified by a search of the MEDLINE database and Cochrane Library. The identified literature was evaluated with respect to the strength of evidence for its efficacy and was then categorized into five levels of evidence (CE A-F) and five levels of recommendation grades (RG 1-5). This second part of the WFSBP guidelines on depressive disorders covers the management of the maintenance phase treatment, and is primarily concerned with the biological treatment (including pharmacological and hormonal medications, electroconvulsive therapy and other brain stimulation treatments) of adults and also, albeit to a lesser extent, children, adolescents and older adults.

Abstract
OBJECTIVE Major depressive disorder (MDD) is a significant public health concern and challenges health care providers to intervene with appropriate treatment. This article provides an overview of efficacy and safety information for duloxetine 60 mg/day in the treatment of MDD, including its effect on painful physical symptoms (PPS). DESIGN A literature search was conducted for articles and pooled analyses reporting information regarding the use of duloxetine 60 mg/day in placebo-controlled trials. SETTING Placebo-controlled, active-comparator, short- and long-term studies were reviewed. PARTICIPANTS Adult (≥18 years) patients with MDD. MEASUREMENTS Effect sizes for continuous outcome (change from baseline to endpoint) and categorical outcome (response and remission rates) were calculated using the primary measures of 17-item Hamilton Rating Scale for Depression (HAMD-17) or Montgomery-Åsberg Depression Rating Scale (MADRS) total score. The Brief Pain Inventory and Visual Analogue Scales were used to assess improvements in PPS. Glass estimation method was used to calculate effect sizes, and numbers needed to treat (NNT) were calculated based on HAMD-17 and MADRS total scores for remission and response rates. Safety data were examined via the incidence of treatment-emergent adverse events and by mean changes in vital-sign measures. RESULTS Treatment with duloxetine was associated with small-to-moderate effect sizes in the range of 0.12 to 0.72 for response rate and 0.07 to 0.65 for remission rate. NNTs were in the range of 3 to 16 for response and 3 to 29 for remission. Statistically significant improvements (p≤0.05) were observed in duloxetine-treated patients compared to placebo-treated patients in PPS and quality of life. The safety profile of the 60-mg dose was consistent with duloxetine labeling, with the most commonly observed significant adverse events being nausea, dry mouth, diarrhea, dizziness, constipation, fatigue, and decreased appetite. CONCLUSION These results reinforce the efficacy and tolerability of duloxetine 60 mg/day as an effective short- and long-term treatment for adults with MDD. The evidence of the independent analgesic effect of duloxetine 60 mg/day supports its use as a treatment for patients with PPS associated with depression. This review is limited by the fact that it included randomized clinical trials with different study designs. Furthermore, data from randomized controlled trials may not generalize well to real clinical practice.

Abstract
Objective: Duloxetine, a selective serotonin and norepinephrine reuptake inhibitor (SNRI), is currently approved
in many countries for the treatment of Major Depressive Disorder (MDD) and Generalized Anxiety Disorder
(GAD). The present naturalistic study was aimed to investigate tolerability of Duloxetine in a sample of patients with affective
disorders and psychiatric/medical comorbidity, comparing tolerability in monotherapy versus polytherapy and
across different age groups. Methods: The sample included 165 patients, affected by anxiety and/or mood disorders with
or without comorbidity, who had been taken Duloxetine for at least 1 month. Sample variables were collected through a
retrospective chart review. Results: Most common primary diagnoses were MDD (49.1 %), Bipolar Disorder (BD) (15.7
%) and GAD (5.5%). The 40 % of the sample had psychiatric comorbidity: in particular, anxiety disorders (15.8 %) (GAD
7.9%, Panic Disorder –PD- 7.3%) and personality disorders (9.1%) as the most frequent ones. With respect to medical
comorbidities (68% of the sample), hypertension (12.1%) and diabetes (7.3%) were the most common ones. Mean duration
of treatment and dosage of Duloxetine were, respectively, 11 months (± 9.1) and 70 mg/day (± 28.6). The 68 % of the
sample received Duloxetine in association with other drugs. Minor side-effects, in particular drowsiness and gastrointestinal
problems, were reported by 15 % of the sample. No difference in terms of tolerability across distinct groups, divided
on the basis of mono- vs polytherapy as well as of different age, was found. Conclusion: Duloxetine, mostly administered in patients with affective disorders with psychiatric/ medical comorbidity and in association with other drugs, appeared to
be well tolerated, showing limited rates of side effects of mild intensity. Further naturalistic studies are warranted to confirm
present results.

Abstract
OBJECTIVE Duloxetine is indicated for treatment of major depressive disorders in the UK. While clinical trials have documented its clinical effectiveness, little is known regarding the relationship between duloxetine use and healthcare utilization in community practice. This study quantifies the impact of treatment with duloxetine on healthcare utilization among patients with depression and those with depression and co-existing pain. METHODS Depressed adults initiating duloxetine during 1/1/2006-9/30/2007 were identified from the General Practice Research Database (GPRD). All-cause hospitalization, accident/emergency visits, specialist referrals, and analgesic use in the 12 months before (pre-period) and after (post-period) duloxetine initiation were compared. Generalized Estimating Equation models evaluated the pre-post change in the odds of hospitalization. RESULTS Nine hundred and nine patients were identified, 413 had pre-period unexplained pain (UPain). Rates of hospitalization declined from the pre- to the post-period. Fewer UPain patients received analgesics post-duloxetine initiation. Multivariate analyses confirmed that the odds of hospitalization were lower after duloxetine initiation. UPain patients with pre-period anticonvulsant use had lower odds of hospitalization in the post-period and the reduction in odds was significantly larger than that of patients without pre-period anticonvulsants. While patients with pre-period anxiolytic use, alcohol/drug dependence, or sleep disorders did not show statistically significant pre-post change in the odds of hospitalization, these changes were significantly different from patients without these conditions. LIMITATIONS The study did not include a comparison group of patients who were non-users of duloxetine. Prevalence of chronic conditions might be under-estimated due to coding in the GPRD. Medications were assumed to be taken as prescribed. Study results are not generalizable beyond the population covered by the UK's primary care system. CONCLUSIONS All-cause hospitalization rates lowered among depressed patients and fewer UPain patients received analgesics post-duloxetine initiation. The reduction in the odds of hospitalization was most pronounced among UPain patients receiving pre-period anticonvulsants.

Abstract
INTRODUCTION Untreated or inadequately treated depression is the largest risk factor for suicide. However, treatment with different antidepressants can have considerable adverse effects, including the increase of the frequency of suicidal thoughts and behavior. This review summarizes the frequency and severity of adverse events observed during the treatment of depression with duloxetine and considers their relevance to clinical practice. AREAS COVERED A comprehensive review of the literature was conducted using PubMed and Medline databases listing data published until December 2010. Articles describing safety and tolerability of duloxetine were selected and reference lists of these articles were scrutinized for further relevant papers. In addition, US and EU Summaries of Product Characteristics were studied. EXPERT OPINION Treatment with duloxetine was associated with mild to moderate adverse events; sexual dysfunction, nausea, headache, dry mouth, somnolence and dizziness being the most frequent among them. No increase in death from suicide and suicidal thoughts and behavior were detected as compared to placebo. So as to avoid discontinuation syndrome as a consequence of abrupt withdrawal of duloxetine, 2 weeks tapering has been recommended before discontinuation. Overall, duloxetine was found to be well tolerated and can be safely administered even in older patients and in those with concomitant illnesses.

Abstract
Adherence and persistence with medication therapy are important in the management of major depressive disorder. This study examined the association between initial prescription dosage of duloxetine and its adherence and persistence. In a large commercial managed-care claims database, 6132 patients with major depressive disorder were initiated on duloxetine between 1 July 2005 and 30 June 2006 at low dose (<60 mg/day, n=1989), mid dose (60 mg/day, n=3733), or high dose (>60 mg/day, n=410). Adherence was defined as medication possession ratio more than or equal to 0.8, and persistence was defined as the length of therapy without exceeding a 15-day gap. Over a 6-month period after duloxetine initiation, mid-dose initiated patients had a higher adherence rate (42.2%) than low-dose (35.6%, P<0.001) or high-dose initiated patients (36.1%, P<0.001). Mid-dose duloxetine-initiated patients stayed significantly longer with the medication (107.3 days) compared with low-dose (95.8 days, P<0.01) or high-dose patients (95.4 days, P<0.01). After adjustment for baseline demographics, comorbid conditions, and prior medications, mid-dose initiated patients remained to have better adherence and longer persistence than low-dose or high-dose initiators. The findings suggest that patients initiated with a dose of 60 mg/day of duloxetine seem to be more adherent to and persistent with the medication than those initiated with less or more than 60 mg/day.
