Second Generation Antipsychotic

Bipolar disorder is a common and serious illness usually requiring long term medication. We critically review the available evidence surrounding the increasing use of quetiapine, a second generation antipsychotic, in both the acute and maintenance phases of bipolar disorder. Large scale, randomized controlled data supports the use of quetiapine in both acute mania and acute bipolar depression, as a safe and effective treatment and probably best used in combination with a traditional ‘mood stabiliser’ such as lithium or divalproex. Also, quetiapine monotherapy has been shown to be effective in bipolar depression. Two recently published studies also confirm that quetiapine in combination with either lithium or divalproex ‘adds value’ to the maintenance treatment of bipolar disorder in terms of delaying relapse compared to either lithium or divalproex alone. Quetiapine is generally well tolerated, although further work on long term weight gain and emergent diabetes would be helpful.

AbstractThis monograph summarizes the proceedings of a roundtable meeting convened to discuss the role of carbamazepine in the treatment of bipolar disorder, in light of new data and the recent indication of carbamazepine extended-release capsules (CBZ ERC) for use in the treatment of acute manic and mixed episodes. Two lectures were presented, followed by a panel discussion among all 6 participants. A summary of the two pivotal trials of CBZ ERC and their pooled data along with other relevant data is presented first. Next, historical trends of carbamazepine and the agent's use in acute mania, bipolar depression, and maintenance are reviewed, emphasizing clinical implications of efficacy, safety, tolerability, and drug interactions. Finally, the panel discussion provides recommendations for the use of carbamazepine in different phases of the illness, taking into account adverse effects and drug-drug interactions.Panel discussants agree that current data confirm the utility of CBZ ERC as an effective treatment for acute manic and mixed episodes in bipolar disorder. Carbamazepine may also prove to be an option for maintenance treatment. Tolerability of the drug is related to dose and titration, and overall safety limitations regarding carbamazepine usage are comparable to other medications. For some patients, the main challenges to use of carbamazepine may be common drug-drug interactions and increased side effects related to aggressive introduction during treatment of acute manic and mixed episodes. Thus, carbamazepine may be a lower priority option for patients who are taking multiple medications, such as elderly individuals with medical comorbidity, due to the potential for drug interactions. Important benefits of carbamazepine include the low propensity toward weight gain and evidence of good tolerability with long-term treatment. (At present there are no available data from long-term, placebo-controlled studies evaluating the effects of carbamazepine or CBZ ERC on weight.) Thus, carbamazepine may be a good option for patients who are concerned about weight gain or who are intolerant of or respond poorly to other medications. Further efforts are needed to update physicians on the use of carbamazepine relative to other medications in the treatment of bipolar disorder.

Background:The optimal duration of antidepressant treatment in bipolar depression appears to be controversial due to a lack of quality evidence, and guideline recommendations are either vague or contradictive. This is especially true for second line treatments such as bupropion that had not been subject to rigourous long term studies in Bipolar Disorder.Case presentation:We report the case of a 75 year old woman who presented with treatment refractory bipolar depression. Because of insufficient response to previous mood stabilizer treatment and refractory depressive symptoms, bupropion was added to venlafaxine and lamotrigine. From there onwards, the patient improved continuously without experiencing deterioration of depression or a switch into hypomania. Our patient being on antidepressants for allmost four years experienced an obvious benefit from longterm antidepressant administration.Conclusion:Noradrenergic/dopaminergic mechanisms of action may play a more prominent role in bipolar depression, and may still be underused as a therapeutic strategy in the acute phase as well as in long-term maintenance in at least a subgroup of bipolar patients. There is still a lack of evidence from RCTs, but this case report further supports antidepressant long-term continuation and the usefulness of a noradrenergic/dopaminergic antidepressant in the acute and maintenance treatment of bipolar disorder.

Prevention Of Relapse

ABSTRACTEffective treatments for the prevention of relapse and recurrence of mood episodes in patients with bipolar disorder are essential to reduce the high mortality associated with this condition, and to improve long-term outcomes. While lithium is considered to be effective as a first line maintenance treatment, additional treatment options would provide clinicians with tools to address the needs of individual patients. The efficacy of olanzapine, an atypical antipsychotic, for the prevention of relapse in bipolar disorder has been demonstrated in several randomized controlled double-blind clinical trials, both as monotherapy and in combination with other agents. The data reviewed herein suggest a more robust efficacy of treatment with olanzapine in the prevention of relapse into manic episodes than into depressive episodes. The adverse events observed most frequently in patients treated with olanzapine relative to comparators were related to somnolence (somnolence, fatigue, or hypersomnia) and weight gain (weight gain, or increased appetite). Moreover, a larger proportion of olanzapine-treated patients than comparator-treated patients experienced clinically important weight gain.

Due to the episodic and chronic nature of bipolar disorder, maintenance therapy represents a critical part of treatment. However, there is a paucity of studies comparing effectiveness of available long-term treatments. In this chapter, the efficacy and safety of pharmacological treatments for maintenance treatment of bipolar disorder, as deriving from the results of randomized controlled trials, will be critically reviewed. These include second-generation antipsychotics aripiprazole, olanzapine, quetiapine, risperidone long-acting injection, ziprasidone, paliperidone, and mood stabilizers lamotrigine, lithium, valproate, carbamazepine, and oxcarbazepine. In general, if a patient has responded satisfactorily to a certain drug during the acute phase, the same treatment should be maintained during maintenance treatment. This was confirmed in two randomized controlled trials. This chapter summarizes the characteristics of the placebo-controlled randomized controlled trials for all the antipsychotics used for maintenance treatment of bipolar disorder.

Future Direction

Ketamine has been shown to be efficacious for the treatment of depression, specifically among individuals who do not respond to first-line treatments. There is still, however, a lack of clarity surrounding the clinical features and response periods across samples that respond to ketamine. This paper systematically reviews published randomized controlled trials that investigate ketamine as an antidepressant intervention in both unipolar and bipolar depression to determine the specific clinical features of the samples across different efficacy periods. Moreover, similarities and differences in clinical characteristics associated with acute versus longer-term drug response are discussed. Similarities across all samples suggest that the population that responds to ketamine’s antidepressant effect has experienced chronic, long-term depression, approaching ketamine treatment as a “last resort”. Moreover, differences between these groups suggest future research to investigate the potential of stronger efficacy towards depression in the context of bipolar disorder compared to major depression, and in participants who undergo antidepressant washout before ketamine administration. From these findings, suggestions for the future direction of ketamine research for depression are formed.

Long Term Outcome

Objective: The treatment of bipolar disorder is challenging because of its clinical complexity and availability of multiple treatment options, none of which are ideal mood stabilizers. This survey studies prescription practices of psychiatrists in India and their adherence to guidelines. Method: In total, 500 psychiatrists randomly selected from the Indian Psychiatric Society membership directory were administered a face-to-face 22-item questionnaire pertaining to the management of bipolar disorder. Results: For acute mania, most practitioners preferred a combination of a mood stabilizer and an atypical antipsychotic to monotherapy. For acute depression, there was a preference for a combination of an antidepressant and a mood stabilizer over other alternatives. Electroconvulsive therapy was preferred in the treatment of severe episodes and to hasten the process of recovery. Approximately, 50% of psychiatrists prescribe maintenance treatment after the first bipolar episode, but maintenance therapy was rarely offered lifelong. While the majority (85%) of psychiatrists acknowledged referring to various clinical guidelines, their ultimate choice of treatment was also significantly determined by personal experience and reference to textbooks. Limitations: The study did not study actual prescriptions. Hence, the responses to queries in the survey are indirect measures from which we have tried to understand the actual practices, and of course, these are susceptible to self-report and social-desirability biases. This was a cross-sectional study; therefore, temporal changes in responses could not be considered. Conclusion: Overall, Indian psychiatrists seemed to broadly adhere to recommendations of clinical practice guidelines, but with some notable exceptions. The preference for antidepressants in treating depression is contrary to general restraint recommended by most guidelines. Therefore, the efficacy of antidepressants in treating bipolar depression in the context of Indian psychiatrists’ practice needs to be studied systematically. Not initiating maintenance treatment early in the course of illness may have serious implications on the long-term outcome of bipolar disorder.

The realisation that major depression is often both chronic and recurrent has slowly begun to change the way that depression is diagnosed and treated. In particular, the need for continuation and maintenance treatment is an issue that now deserves increased attention, especially with the availability of new classes of antidepressant treatments, which have excellent efficacy and more favourable side-effect profiles. Although the serious consequences of depressive disorders clearly indicate the need for effective and prompt intervention on the part of clinicians, the results of several studies indicate that patients with depression consistently receive no or low levels of antidepressant therapy. It is hoped that, through continued education of health care providers and patients about the consequences of depression, the issue of undertreatment of this serious illness will be resolved.
