recommendations for antidepressant use in bipolar disorder rated by at least 80% of International Society for Bipolar Disorders experts as essential or important.</div></section><section id="abstract" property="abstract" typeof="Text" role="doc-abstract"><h2 property="name">Abstract</h2><section id="abs-sec-1"><h3>Objective</h3><div role="paragraph">The risk-benefit profile of antidepressant medications in bipolar disorder is controversial. When conclusive evidence is lacking, expert consensus can guide treatment decisions. The International Society for Bipolar Disorders (ISBD) convened a task force to seek consensus recommendations on the use of antidepressants in bipolar disorders.</div></section><section id="abs-sec-2"><h3>Method</h3><div role="paragraph">An expert task force iteratively developed consensus through serial consensus-based revisions using the Delphi method. Initial survey items were based on systematic review of the literature. Subsequent surveys included new or reworded items and items that needed to be rerated. This process resulted in the final ISBD Task Force clinical recommendations on antidepressant use in bipolar disorder.</div></section><section id="abs-sec-3"><h3>Results</h3><div role="paragraph">There is striking incongruity between the wide use of and the weak evidence base for the efficacy and safety of antidepressant drugs in bipolar disorder. Few well-designed, long-term trials of prophylactic benefits have been conducted, and there is insufficient evidence for treatment benefits with antidepressants combined with mood stabilizers. A major concern is the risk for mood switch to hypomania, mania, and mixed states. Integrating the evidence and the experience of the task force members, a consensus was reached on 12 statements on the use of antidepressants in bipolar disorder.</div></section><section id="abs-sec-4"><h3>Conclusions</h3><div role="paragraph">Because of limited data, the task force could not make broad statements endorsing antidepressant use but acknowledged that individual bipolar patients may benefit from antidepressants. Regarding safety, serotonin reuptake inhibitors and bupropion may have lower rates of manic switch than tricyclic and tetracyclic antidepressants and norepinephrine-serotonin reuptake inhibitors. The frequency and severity of antidepressant-associated mood elevations appear to be greater in bipolar I than bipolar II disorder. Hence, in bipolar I patients antidepressants should be prescribed only as an adjunct to mood-stabilizing medications.</div></section></section></div></div><section id="bodymatter" data-extent="bodymatter" property="articleBody" typeof="Text"><div class="core-container"><div role="paragraph">The efficacy and safety of antidepressant drug treatment in bipolar disorder is the subject of long-standing debate based on a scientific literature that is limited and inconsistent (<a href="#B1" role="doc-biblioref" data-xml-rid="B1">1</a>–<a href="#B6" role="doc-biblioref" data-xml-rid="B6">6</a>). The sparseness of high-quality clinical research hampers the formulation of sound clinical recommendations on the use of antidepressants in the treatment of bipolar disorder (<a href="#B7" role="doc-biblioref" data-xml-rid="B7">7</a>–<a href="#B12" role="doc-biblioref" data-xml-rid="B12">12</a>). We propose that a consensus formed by the experience and judgment of clinical and academic bipolar disorder experts, guided by the available research findings, may help in developing at least tentative treatment recommendations as additional research is awaited. Accordingly, the International Society for Bipolar Disorders (ISBD) appointed Dr. Vieta to assemble a task force of international experts to review the evidence base for benefits and risks of antidepressant treatment in bipolar disorder and to formulate clinical recommendations based on the consensus development process. This report represents a consensus statement from this endeavor.</div><section id="sec-1" data-type="methods"><h2>Method</h2><section id="sec-1-1"><h3>Consensus Methods</h3><div role="paragraph">The ISBD Task Force was made up of a panel of global experts on bipolar disorder, selected according to an objective procedure based on a Scopus search of citations on the specific topic of antidepressant use in bipolar disorder (number of citations per candidate during the past 3 years). The most cited authors (including several ISBD nonmembers) and some additional authors from key geographical areas were identified and invited by e-mail to participate; 76% agreed to participate. An introductory meeting was held at the ISBD biennial congress (Istanbul, March 2012), where task force procedures were reviewed and agreed upon. These procedures focused on the discussion and integration of findings from peer-reviewed published research findings on the topic, including reviews and meta-analyses, as well as clinical trial reports. An expert coauthor (I.P.) was appointed to develop a first draft of a systematic review, to be circulated after initial review by the senior author (E.V.). The aims of the task force were to conduct a thorough and balanced review of research findings and to integrate them into an expert consensus, based on clinical experience and judgment, as well as research evidence, and to provide a synthesis of current knowledge supporting clinical recommendations for this important and timely topic. The final section of this report, which summarizes consensus statements, was achieved through a face-to-face meeting, personal and group e-mail correspondence, and serial iterative revisions of the report, in order to provide a final guide on the use of antidepressants in bipolar disorder. Funding for this international project was provided solely by the Spanish government.</div></section><section id="sec-1-2"><h3>Search Strategy</h3><div role="paragraph">We performed an extensive literature search on PubMed, using the following search terms, limited to human studies: antidepressant* AND (mania[ti] OR manic[ti]); antidepressant* AND (bipolar[ti] AND depressi*[ti]); antidepressant* AND (mixed[ti] AND state*[ti]); antidepressant* AND bipolar disorder AND maintenance[ti]; antidepressant* AND bipolar disorder AND comorbid*[ti]; antidepressant* AND switch AND (manic OR mania OR hypomani*); antidepressant* AND (cycle acceleration OR phase shift OR cycle frequen*); and antidepressant* AND (suicid*[ti] OR self-kill*[ti] OR self-harm*[ti]).</div><div role="paragraph">We considered first-generation norepinephrine-serotonin reuptake inhibitors (SNRIs), including tricyclic and tetracyclic antidepressants; monoamine oxidase (MAO) inhibitors; and the modern antidepressants, including the dopamine-norepinephrine reuptake inhibitor bupropion, serotonin reuptake inhibitors (SSRIs), modern SNRIs, the norepinephrine-serotonin autoreceptor-specific antagonists mianserin and mirtazapine; the atypical, mixed monoamine-transporter inhibitors trazodone and nefazodone; and the melatonin M<sub>1</sub> and M<sub>2</sub> receptor agonist and 5-HT<sub>2c</sub> receptor antagonist agomelatine.</div><div role="paragraph">We address here only antidepressant medications, not the treatment of bipolar depression in general.

Statements on antidepressant use in bipolar disorder that could be useful to clinicians were derived from the content of the literature search and classified into six common domains: acute treatment; maintenance treatment; monotherapy; switch to mania, hypomania, or mixed states and rapid cycling; use in mixed states; and drug class. Three survey rounds were conducted to develop consensus. The first survey included open-ended questions at the end of each section inviting participants to add comments and suggestions by e-mail. Later rounds were conducted online using <a href="http://eSurveysPro.com">eSurveysPro.com</a>. The survey was sent to task force members for anonymous responses. Panel members rated survey items ranging from “essential” to “should not be included.” We calculated proportions of respondents rating each item.

Adjunctive antidepressants were no more effective than placebo at any time, and overall, 23.5% of patients given an antidepressant and 27.3% given placebo met criteria for enduring recovery.

In one trial, depressed bipolar I or II patients who responded to initial treatment with venlafaxine, bupropion, or sertraline added to standard mood stabilizers after 2 months (50%−60% of each group) continued these treatments for up to 1 year, and only 15%−25% had no further episodes (<a href="#B37" role="doc-biblioref" data-xml-rid="B37">37</a>, <a href="#B39" role="doc-biblioref" data-xml-rid="B39">39</a>).

Similarly, in a randomized double-blind placebo-substitution study with fluoxetine monotherapy in bipolar II depression (<a href="#B23" role="doc-biblioref" data-xml-rid="B23">23</a>), initial response to antidepressant treatment was associated with fewer relapses if antidepressant treatment was continued for up to 50 weeks.</div></section><section id="sec-2-2-6"><h4>Conclusions.</h4><div role="paragraph">Long-term trials involving addition of antidepressants to ongoing mood-stabilizing treatments are scant and have yielded ambiguous, inconclusive findings, despite a moderately favorable quality score (C) for the evidence and despite reliance on samples enriched for probable short-term antidepressant response.

Moreover, in a study of a large U.S. insurance claims database (<a href="#B51" role="doc-biblioref" data-xml-rid="B51">51</a>), antidepressant treatment was identified in 32% of 2,126 patients with bipolar I disorder following a recent manic or mixed episode, with more rehospitalizations within 12 months with than without an antidepressant.</div></section><section id="sec-2-2-8"><h4>Conclusions.</h4><div role="paragraph">Overall, the lack of controlled studies of antidepressant use in mania and mixed states points to a D quality rating of available evidence (<a href="#T1">Table 1</a>).</div></section></section><section id="sec-2-3"><h3>Safety</h3><section id="sec-2-3-1"><h4>Antidepressants and mood switching.</h4><div role="paragraph">The assessment of antidepressant-associated mood switches into hypomania, mania, or mixed states is a particularly controversial topic. The principal difficulty lies in attributing causality, as mood elevations and changes in cycle frequency occur unpredictably in the natural course of bipolar disorder, making it difficult to distinguish spontaneous from antidepressant-induced switching (<a href="#B52" role="doc-biblioref" data-xml-rid="B52">52</a>). Randomized trials evaluating the risk of switches with antidepressant treatment with and without a mood stabilizer are few and difficult to interpret, owing to methodological limitations (<a href="#B53" role="doc-biblioref" data-xml-rid="B53">53</a>–<a href="#B57" role="doc-biblioref" data-xml-rid="B57">57</a>). Moreover, the definition of mood switching lacks consensus among experts (<a href="#B58" role="doc-biblioref" data-xml-rid="B58">58</a>). In an attempt to clarify the terminology of antidepressant-associated mood elevations, the ISBD reached consensus in recommending use of the term “treatment-emergent affective switch” instead of antidepressant-induced switch (<a href="#B59" role="doc-biblioref" data-xml-rid="B59">59</a>), to emphasize association without implying causality. The ISBD definition of treatment-emergent affective switch provides operational criteria that consider factors such as timing, duration, and severity of mood changes in attributing probable causation to antidepressant treatment. Obviously, since these criteria are very recent, they have not yet been widely tested or adopted.</div><div role="paragraph">Despite these definitional shortcomings, a notably consistent finding from randomized controlled trials of antidepressants in bipolar patients is that of differences among types of antidepressants in their association with mood switches (<a href="#B54" role="doc-biblioref" data-xml-rid="B54">54</a>). For example, a small 8-week prospective double-blind trial comparing adjunctive bupropion or desipramine in bipolar depression (<a href="#B60" role="doc-biblioref" data-xml-rid="B60">60</a>) found hypomania or mania in five of 10 desipramine-treated patients but in only one of nine bupropion-treated patients. However, several placebo-controlled randomized controlled trials did not find elevated switch rates with SSRIs or bupropion, either as adjuncts to mood stabilizers or as monotherapy (<a href="#B54" role="doc-biblioref" data-xml-rid="B54">54</a>). In a previously described 6-month double-blind placebo-controlled trial (<a href="#B25" role="doc-biblioref" data-xml-rid="B25">25</a>), rates of mood elevations were indistinguishable (10.1% compared with 10.7%) between subjects receiving a mood stabilizer plus an antidepressant (bupropion or paroxetine, N=179) and those receiving a mood stabilizer plus placebo (N=197).</div><div role="paragraph">Even in monotherapy, it is not clear whether SSRIs increase the risk of mood switching. In one randomized controlled trial (<a href="#B20" role="doc-biblioref" data-xml-rid="B20">20</a>), paroxetine (20 mg/day) was not associated with more mood switching than placebo. In a 12-month trial (<a href="#B37" role="doc-biblioref" data-xml-rid="B37">37</a>), the risk of antidepressant-associated switching ranked was 9% for sertraline, 10% for bupropion, and 29% for venlafaxine. A short-term (6-week) study (<a href="#B27" role="doc-biblioref" data-xml-rid="B27">27</a>) also found more mood switching with venlafaxine than with paroxetine in depressed bipolar I and II patients. These findings suggest that mood switching may be limited to certain antidepressant classes, such as the tri- and tetracyclics and venlafaxine, and that dosages, co-treatments, exposure times, types of bipolar patients, and criteria for “switching” may each have a role. Several meta-analyses have evaluated antidepressant-associated switch risk. In an early meta-analysis (<a href="#B61" role="doc-biblioref" data-xml-rid="B61">61</a>), the rate of treatment-emergent switch occurred substantially more often with tri- and tetracyclics (11.2%) than with SSRIs (3.7%) or placebo (4.2%). A subsequent meta-analysis (<a href="#B29" role="doc-biblioref" data-xml-rid="B29">29</a>) found that, with the exception of tri- and tetracyclics and venlafaxine, switching was uncommon. Another review (<a href="#B54" role="doc-biblioref" data-xml-rid="B54">54</a>) found that treatment with or without antidepressants did not increase the risk of switching in bipolar patients (types I or II) compared with rates of spontaneous switching (15.3% and 13.8%, respectively). Nevertheless, tri- and tetracyclics carried a higher risk for new mania-hypomania than SSRIs or MAO inhibitors. Another review (<a href="#B30" role="doc-biblioref" data-xml-rid="B30">30</a>) found that SSRIs and bupropion were not associated with more switching than placebo during short-term treatment, but noted that studies employing sensitive criteria to define switching reported higher switch rates for tri- and tetracyclics and venlafaxine than for SSRIs and bupropion.</div><div role="paragraph">Regarding the issue of whether mood stabilizers protect against antidepressant treatment-associated mood switching, a comprehensive review (<a href="#B54" role="doc-biblioref" data-xml-rid="B54">54</a>) found a lack of evidence that treatment with mood stabilizers protects against mood elevation in bipolar patients, with or without antidepressant co-treatment, but noted a lack of appropriate controls or randomization with which to make an adequate assessment. However, one study (<a href="#B62" role="doc-biblioref" data-xml-rid="B62">62</a>) found a higher risk of mood switching in bipolar disorder than in unipolar depression (2.50%/week compared with 0.275%/week), even though 70% of the bipolar patients were receiving antidepressant-mood stabilizer combinations, whereas most unipolar patients received an antidepressant alone. Questions about antidepressant-associated switching include that of the risks associated with many specific antidepressants and effects of dosage, for which there is insufficient evidence. For example, most studies of SSRIs have involved sertraline or paroxetine, and effects of MAO inhibitors are virtually unknown (<a href="#B54" role="doc-biblioref" data-xml-rid="B54">54</a>, <a href="#B63" role="doc-biblioref" data-xml-rid="B63">63</a>–<a href="#B65" role="doc-biblioref" data-xml-rid="B65">65</a>).</div><div role="paragraph">Besides the effect of antidepressant type, the risk of switch may also vary according to bipolar type. An early study (<a href="#B63" role="doc-biblioref" data-xml-rid="B63">63</a>) suggested that patients with bipolar I disorder are at higher risk of switching than those with bipolar II disorder, a finding that was supported in a post hoc analysis from the Stanley Foundation Bipolar Network study (<a href="#B66" role="doc-biblioref" data-xml-rid="B66">66</a>). Four previously discussed studies also suggested a low risk of switching for bipolar disorder II patients, even when treated with antidepressant monotherapy (<a href="#B21" role="doc-biblioref" data-xml-rid="B21">21</a>–<a href="#B23" role="doc-biblioref" data-xml-rid="B23">23</a>, <a href="#B67" role="doc-biblioref" data-xml-rid="B67">67</a>).</div><div role="paragraph">A systematic meta-analytic review of 13 prospective studies (<a href="#B68" role="doc-biblioref" data-xml-rid="B68">68</a>) supported the impression that bipolar I patients have a higher antidepressant-associated switch rate than bipolar II patients (relative risk=1.78, p=0.002), although bipolar I cases involved mania as well as the hypomania found with bipolar II disorder. These findings suggest greater clinical safety with use of antidepressants in patients with bipolar II disorder (<a href="#B69" role="doc-biblioref" data-xml-rid="B69">69</a>), although even hypomania can be problematic.</div><div role="paragraph">Most information regarding clinical correlates of risk of mood switching during antidepressant treatment comes from retrospective or post hoc analyses.

Finally, a history of antidepressant-associated mood switching, lower rates of previous clinical benefit from antidepressant treatment, and multiple previous antidepressant trials have been associated with subsequent mood switches, generally more severe illness, and worse long-term outcomes (<a href="#B74" role="doc-biblioref" data-xml-rid="B74">74</a>–<a href="#B76" role="doc-biblioref" data-xml-rid="B76">76</a>).</div><div role="paragraph">Regarding antidepressant monotherapy and the risk of treatment-emergent affective switches, one study (<a href="#B77" role="doc-biblioref" data-xml-rid="B77">77</a>) found that depressed bipolar patients first exposed to antidepressant monotherapy had higher switch rates and more suicide attempts than those treated with antidepressant-mood stabilizer combinations.

Two retrospective clinical studies (<a href="#B77" role="doc-biblioref" data-xml-rid="B77">77</a>, <a href="#B94" role="doc-biblioref" data-xml-rid="B94">94</a>) found more suicidal behaviors in patients receiving antidepressants than in those receiving mood stabilizers with or without antidepressants. A prospective study (<a href="#B95" role="doc-biblioref" data-xml-rid="B95">95</a>) of 425 bipolar patients treated with antidepressants for a new major depressive episode found no evidence of more or less new suicidal ideation or behavior with antidepressant exposure. Similarly, in 789 mood disorder patients (unipolar major depression, N=605; bipolar disorder, N=184), antidepressant treatment was not associated with altered risk of suicidal thoughts or acts, based on changes in the suicide item of the Hamilton Depression Rating Scale at the start of and after 3.6 months of sustained antidepressant treatment (<a href="#B96" role="doc-biblioref" data-xml-rid="B96">96</a>).</div><div role="paragraph">However, in 757 patients with unipolar or bipolar depression, during periods in which patients were exposed to antidepressants, rates of suicidal behaviors appeared to be 35%−54% lower (more in bipolar I disorder) than without antidepressant treatment (<a href="#B97" role="doc-biblioref" data-xml-rid="B97">97</a>, <a href="#B98" role="doc-biblioref" data-xml-rid="B98">98</a>). These observations are at odds with the proposal that antidepressant treatment may increase suicidal risk in some young patients with unipolar depressive or anxiety disorders—possibly by inducing agitated-dysphoric states in those with unrecognized bipolar disorder, or as a direct toxic effect of the treatment (<a href="#B33" role="doc-biblioref" data-xml-rid="B33">33</a>, <a href="#B44" role="doc-biblioref" data-xml-rid="B44">44</a>, <a href="#B57" role="doc-biblioref" data-xml-rid="B57">57</a>, <a href="#B99" role="doc-biblioref" data-xml-rid="B99">99</a>).</div><div role="paragraph">In 1,380 depressed bipolar I or II patients (<a href="#B83" role="doc-biblioref" data-xml-rid="B83">83</a>), the presence of subsyndromal hypomanic symptoms was associated with more previous suicide attempts, and similar results were found in another large study (<a href="#B84" role="doc-biblioref" data-xml-rid="B84">84</a>). Three recent studies have found an association of lifetime mixed episodes and higher rates of antidepressant use with increased risk of suicide behaviors (<a href="#B49" role="doc-biblioref" data-xml-rid="B49">49</a>, <a href="#B50" role="doc-biblioref" data-xml-rid="B50">50</a>, <a href="#B100" role="doc-biblioref" data-xml-rid="B100">100</a>). In a study of 290 patients with bipolar I or II disorder (<a href="#B101" role="doc-biblioref" data-xml-rid="B101">101</a>), suicidal ideation or acts were found to be associated with more previous antidepressant trials (or more depressive morbidity). Also, in a study of 138 children and adolescents diagnosed with bipolar disorder (<a href="#B102" role="doc-biblioref" data-xml-rid="B102">102</a>), suicidal ideation and attempts were more likely in episodes of mixed agitated-depression.</div></section><section id="sec-2-3-8"><h4>Conclusions.</h4><div role="paragraph">Overall, the evidence of an association of either decreased or increased suicidal risk with antidepressant treatment in bipolar patients is rated D (<a href="#T1">Table 1</a>), largely because adequate designs are unfeasible because of the relative rarity of suicide, even among mood disorder patients with suicidal thoughts, and because of the challenge of designing ethical studies of effects of treatment on suicidal risk. Currently, it remains unclear whether antidepressants might decrease or increase suicidal risk.</div></section></section></section><section id="sec-3"><h2>Consensus Statements</h2><div role="paragraph">Based on findings from the clinical studies considered above, the available evidence concerning both the value and the risks of antidepressant treatment in bipolar disorder is remarkably limited, and much of it is methodologically weak. Therefore, it is not currently possible to make firm clinical recommendations that are soundly evidence based. There was consensus in this ISBD Task Force that non-antidepressant treatments, including lithium, lamotrigine, olanzapine, quetiapine, and lurasidone, should be considered as monotherapy before using antidepressants in bipolar depression. If antidepressants are used in bipolar I disorder, they should be prescribed along with a mood-stabilizing treatment, even though the evidence for antidepressant-associated mood switching is mixed and the ability of mood stabilizers to prevent such responses to antidepressant treatment unproven. Antidepressants in the treatment of acute depression in bipolar II disorder appear to be relatively well tolerated but may or may not be effective. Evidence for the long-term prophylactic value of antidepressant treatment for patients with bipolar I or II disorder remains poorly studied, despite the common clinical use of antidepressants, ideally in combination with a mood stabilizer. There is little evidence to support the proposition that one type of antidepressant, at clinically equivalent doses, is more or less effective or dangerous than another. Exceptions are tri- and tetracyclics and venlafaxine, which appear to carry a particularly high risk of inducing pathologically elevated states of mood and behavior.</div><div role="paragraph">In short, we conclude that the use of antidepressants to treat depressive phases or components of bipolar disorder can neither be condemned nor endorsed without carefully evaluating individual clinical cases and circumstances. For these reasons, the intention of this ISBD Task Force consensus is to ascertain, as far as possible, how best to use antidepressants to treat patients with bipolar disorder. No simple guidelines can be provided at this time, but clinicians are encouraged to consult our consensus-based recommendations (<a href="#T2">Table 2</a>). We strongly encourage further research to clarify the many remaining major and urgent clinical questions concerning optimally effective and safe treatment of depressive components of bipolar disorder.</div></section></div></section><section id="backmatter" data-extent="backmatter"><div class="core-container"><section id="footnotes"><h2>Footnote</h2><div role="doc-footnote"><div id="fn2" role="paragraph">Dr. Koukopoulos died in April 2013.</div></div></section><section id="supplementary-materials" class="core-supplementary-materials"><h2>Supplementary Material</h2><div role="list"><div class="core-supplementary-material" role="listitem"><div class="core-description"><span class="core-label">Supplementary Material</span> <span class="core-filename">(1249_ds001.pdf)</span></div><div class="core-link"><ul><li><a href="/doi/suppl/10.1176/appi.ajp.2013.13020185/suppl_file/1249_ds001.pdf" target="_blank">View/Download</a></li><li>15.90 KB</li></ul></div></div></div></section><section id="bibliography" role="doc-bibliography"><h2>References</h2><div role="list"><div role="listitem" data-has="label"><div class="label">1.</div><div id="B1" class="citations"><div class="citation"><div class="citation-content">Pacchiarotti I, Mazzarini L, Colom F, Sánchez-Moreno J, Girardi P, Kotzalidis GD, Vieta E: Treatment-resistant bipolar depression: towards a new definition. <em>Acta Psychiatr Scand</em> 2009; 120:429–440</div><div class="external-links"><div class="core-xlink-crossref"><a href="https://doi.org/10.1111/j.1600-0447.2009.01471.x">Crossref</a></div><div class="core-xlink-pubmed"><a href="https://pubmed.ncbi.nlm.nih.gov/19740127/">PubMed</a></div><div class="core-xlink-google-scholar"><a href="https://scholar.google.com/scholar_lookup?title=Treatment-resistant+bipolar+depression%3A+towards+a+new+definition&author=I+Pacchiarotti&author=L+Mazzarini&author=F+Colom&author=J+S%C3%A1nchez-Moreno&author=P+Girardi&author=GD+Kotzalidis&author=E+Vieta&publication_year=2009&journal=Acta+Psychiatr+Scand&pages=429-440&doi=10.1111%2Fj.1600-0447.2009.01471.x&pmid=19740127">Google Scholar</a></div></div></div></div></div><div role="listitem" data-has="label"><div class="label">2.</div><div id="B2" class="citations"><div class="citation"><div class="citation-content">Bauer M, Ritter P, Grunze H, Pfennig A: Treatment options for acute depression in bipolar disorder. <em>Bipolar Disord</em> 2012; 14(suppl 2):37–50</div><div class="external-links"><div class="core-xlink-crossref"><a href="https://doi.org/10.1111/j.1399-5618.2012.00991.x">Crossref</a></div><div class="core-xlink-pubmed"><a href="https://pubmed.ncbi.nlm.nih.gov/22510035/">PubMed</a></div><div class="core-xlink-google-scholar"><a href="https://scholar.google.com/scholar_lookup?title=Treatment+options+for+acute+depression+in+bipolar+disorder&author=M+Bauer&author=P+Ritter&author=H+Grunze&author=A+Pfennig&publication_year=2012&journal=Bipolar+Disord&pages=37-50&doi=10.1111%2Fj.1399-5618.2012.00991.x&pmid=22510035">Google Scholar</a></div></div></div></div></div><div role="listitem" data-has="label"><div class="label">3.</div><div id="B3" class="citations"><div class="citation"><div class="citation-content">Goldberg JF: Antidepressants: the scapegoat of poor outcome bipolar disorder?
