There is a paucity of controlled clinical data on the best initial therapy for treating patients with bipolar type II (BP II) major depressive episode (MDE). In this analysis, we examined the safety and antidepressant efficacy of short-term venlafaxine versus lithium monotherapy in rapid and non-rapid cycling patients with BP II MDE. We hypothesized that lithium would have superior efficacy to venlafaxine, with fewer syndromal and sub-syndromal hypomanic and mixed mood conversions in the rapid cycling BP II MDE patients.

    • "No studies on the efficacy of mirtazapine for bipolar disorder exist. Concerning venlafaxine, its efficacy in the treatment of bipolar II depression has been shown in small sample sizes only [33-35] and one study shows that venlafaxine may trigger switches to mania [36]. Recent reviews and studies on the efficacy of antidepressants alone or in combination in the treatment of bipolar depression do not find stable effects for their efficacy [37-42]. "

    ABSTRACT: Background For the pharmacological treatment of bipolar depression several guidelines exist. It is largely unknown, to what extent the prescriptions in daily clinical routine correspond to these evidence based recommendations and which combinations of psychotropic drugs are frequently used. Methods The prescriptions of psychotropic drugs were investigated of all in-patients with bipolar depression (n = 2246; time period 1994–2009) from hospitals participating in the drug surveillance program AMSP. For the drug use in 2010, 221 cases were analysed additionally. Results From 1994 to 2009, 85% of all patients received more than one class of psychotropic substances: 74% received antidepressants in combination therapy, 55% antipsychotics, 48% anticonvulsants and 33% lithium. When given in combination, lithium is the most often prescribed substance for bipolar depression (33%), followed by valproic acid (23%), mirtazapine and venlafaxine (16% each), quetiapine (15%), lamotrigine (14%) and olanzapine (13%). Both, lithium and valproic acid are often combined with selective serotonin reuptake inhibitors (SSRI), but also with mirtazapine und venlafaxine. Combinations of more than one antidepressant occur quite often, whereby combinations with bupropion, paroxetine, fluoxetine or fluvoxamine are very rare. In 2010, quetiapine (alone and combined) was the most frequently prescribed drug (39%); aripiprazole was administered in 10%. Conclusion Combinations of antidepressants (SSRI, mirtazapine, venlafaxine) with mood stabilizers (lithium, valproic acid, lamotrigine) and / or atypical antipsychotics (quetiapine, olanzapine) are common. Of most of those combinations the efficacy has not been studied. The use of aripiprazole and the concomitant use of two or three antidepressants contrast the guidelines.

    • "Following a 12-week observation period, venlafaxine surpassed lithium both in response rates (58.1% versus 20.0%; P < 0.0005) and in remission rates (44.2% versus 7.5%; P < 0.0005), with no significant increase in mean YMRS scores [17]. A secondary analysis of the data showed no difference in treatment response between rapid and nonrapid cyclers [18]. Switch to venlafaxine treatment for lithium nonresponders resulted in a significant improvement in depressive symptoms, with no evidence of manic induction over a follow-up period of 12 weeks [19]. "

    ABSTRACT: While studies in the past have focused more on treatment of the manic phase of bipolar disorder (BD), recent findings demonstrate the depressive phase to be at least as debilitating. However, in contrast to unipolar depression, depression in bipolar patients exhibits a varying response to antidepressants, raising questions regarding their efficacy and tolerability. Methods. We conducted a MEDLINE and Cochrane Collaboration Library search for papers published between 2005 and 2011 on the subject of antidepressant treatment of bipolar depression. Sixty-eight articles were included in the present review. Results. While a few studies did advocate the use of antidepressants, most well-controlled studies failed to show a robust effect of antidepressants in bipolar depression, regardless of antidepressant class or bipolar subtype. There was no significant increase in the rate of manic/hypomanic switch, especially with concurrent use of mood stabilizers. Prescribing guidelines published in recent years rely more on atypical antipsychotics, especially quetiapine, as a first-line therapy. Conclusions. Antidepressants probably have no substantial role in acute bipolar depression. However, in light of conflicting results between studies, more well-designed trials are warranted.

    • "Symptoms of panic exacerbation can be managed with short-term benzodiazepine coverage. Acutely emergent hypomanic or manic symptoms are best treated with an antipsychotic agent; no preferred treatment has been established for rapid bipolar cycling.105 An antidepressant medication should not be prematurely discontinued unless this is clearly necessary (eg, following the occurrence of rapid, unmanageable weight gain).

    ABSTRACT: When treatments are ordered for adolescent major depression, or for other adolescent medical illnesses, adherence and clinical outcomes are likely to be unsatisfactory, unless 4 basic principles of the medical treatment of adolescent illness are implemented. These comprise providing effective patient and parent/caregiver education, establishing effective patient and caregiver therapeutic alliances, providing effective treatment, and managing other factors associated with treatment adherence as indicated. The goals of treatment are to achieve the earliest possible response and remission. Failure to treat adolescent major depression successfully has potentially serious consequences, including worsened adherence, long-term morbidity, and suicide attempt. Accordingly, prescribed treatment must be aggressively managed. Doses of an antidepressant medication should be increased as rapidly as can be tolerated, preferably every 1-2 weeks, until full remission is achieved or such dosing is limited by the emergence of unacceptable adverse effects. A full range of medication treatment options must be employed if necessary. Treatment adherence, occurrence of problematic adverse effects, clinical progress, and safety must be systematically monitored. Adolescents with major depression must be assessed for risk of harm to self or others. When this risk appears significant, likelihood of successful outcomes will be enhanced by use of treatment plans that comprehensively address factors associated with treatment nonadherence. Abbreviated and comprehensive plans for the treatment of potentially fatal adolescent illnesses are outlined in this review.
