Abstract
INTRODUCTION Rapid cycling bipolar disorder (RCBD) is defined as four or more affective episodes (depression, mania or hypomania) within 1 year. RCBD has a high point of prevalence (from 10% to 20% among clinical bipolar samples) and is associated with greater severity, longer illness duration, worse global functioning and higher suicidal risk, but there is no consensus on treatment option. The use of several pharmacological agents has been reported (levothyroxine, antipsychotics, antidepressants and mood stabilizers). OBJECTIVE The main objective of this review was to propose a critical review of the literature and to rank the pharmacological agent using a level of evidence (LEO) adapted from the Center for Evidence-Based Medicine, and to illustrate it with a case report on off-label intravenous ketamine. METHOD We conducted a review using the MeSH terms and keywords (bipolar [Title/Abstract]) AND (rapid [Title/Abstract]) AND (cycling [Title/Abstract]) AND (treatment [Title/Abstract]). Alexis Bourla and Stéphane Mouchabac screened 638 documents identified through literature search in Medline (PubMed) or by bibliographic references and 164 abstracts were then analyzed. Nonpharmacological treatments were excluded. RESULT Seventy articles were included in the review and divided into six categories: mood stabilizers, antipsychotics, hormonal treatments, ketamine and other pharmacological treatments. DISCUSSION Our review highlights the heterogeneity of the pharmacological treatment of RCBD and no clear consensus can emerge.

Abstract
Background and Objectives: This review is dedicated to the use of carbamazepine and its derivatives oxcarbazepine and eslicarbazepine in bipolar disorder and their relative strengths in treating and preventing new depressive or manic episodes. This paper will discuss the evidence of their efficacy relative to the polarity of relapse from controlled acute and maintenance/relapse prevention studies in bipolar patients. Materials and Methods: A Medline search was conducted for controlled acute and maintenance studies with carbamazepine, oxcarbazepine, and eslicarbazepine in bipolar disorder. In addition, abstracts reporting on controlled studies with these medications from key conferences were taken into consideration. Results: Information was extracted from 84 articles on the acute and prophylactic efficacy of the medications under consideration. They all appear to have stronger efficacy in treating acute mania than depression, which also translates to better protection against manic than depressive relapses for carbamazepine. Still, there is a paucity of controlled acute studies on bipolar depression for all and, with the exception of carbamazepine, a lack of long-term monotherapy maintenance data. For eslicarbazepine, the efficacy in bipolar disorder remains largely unknown. Especially with carbamazepine, tolerability issues and drug-drug interactions need to be kept in mind. Conclusions: Two of the medications discussed in this review, carbamazepine and oxcarbazepine, match Class A criteria according to the criteria proposed by Ketter and Calabrese, meaning acute antimanic efficacy, prevention of manic relapses, and not causing or worsening depression.

A randomized controlled trial comparing lithium plus valproic acid versus lithium plus carbamazepine in young patients with type 1 bipolar disorder: the LICAVAL study. Trials 2019; 20:608. [PMID: 31655626 PMCID: PMC6815353 DOI: 10.1186/s13063-019-3655-2] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2019] [Accepted: 08/13/2019] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Treatment of bipolar disorder (BD) usually requires drug combinations. Combinations of lithium plus valproic acid (Li/VPA) and lithium plus carbamazepine (Li/CBZ) are used in clinical practice but were not previously compared in a head-to-head trial. OBJECTIVE The objective of this trial was to compare the efficacy and tolerability of Li/VPA versus Li/CBZ in treating type 1 BD in any phase of illness in young individuals. METHODS LICAVAL was a randomized, unicenter, open-label, parallel-group trial that was conducted from January 2009 to December 2012 in a tertiary hospital in São Paulo, Brazil. Participants were between 18 and 35 years old and were followed up for 2 years. Our primary outcome was the number of participants achieving/maintaining response and remission during the acute and maintenance phases of BD treatment, respectively. Other outcomes assessed were symptom severity and adverse events throughout the study. In the analysis of the primary outcome, we compared groups by using a two-way repeated measures analysis of variance and estimated effect sizes by using Cohen's d. RESULTS Of our 64 participants, 36 were allocated to Li/VPA and 28 to Li/CBZ. Our sample was composed predominantly of females (66.6%) and the average age was 27.8 years. A total of 27 (45.0%) participants had depression, 17 (28.3%) had mania/hypomania, and 16 (26.7%) had a mixed state. We found no between-group differences in CGI-BP (Clinical Global Impression Scale modified for use in bipolar disorder) scores (P = 0.326) or in any other outcome. Side effects differed significantly between groups only in the first week of treatment (P = 0.021), and there were more side effects in the Li/VPA group. Also, the Li/VPA group gained weight (+2.1 kg) whereas the Li/CBZ group presented slight weight loss (-0.2 kg). CONCLUSION Our study suggests that Li/VPA and Li/CBZ have similar efficacy and tolerability in BD but that Li/CBZ might have metabolic advantages in the long term.

Abstract
The management of bipolar disorder has seen significant evolution in terms of the number of treatment options now approved for both the acutely manic phase and the maintenance stages of the illness. In addition, new formulations of traditional agents are available for clinicians to use in their treatment approach. One such example is carbamazepine, which has approval by the United States Food and Drug Administration for the treatment of acute and mixed mania in an extended-release formulation that uses a three-bead delivery system. Although the parent compound has been available for decades, its approval for bipolar disorder is recent despite numerous clinical trials that have supported its use in both the acute and maintenance phases of bipolar disorder. Advantages of the new formulation include less fluctuation in plasma concentration and, in general, improved tolerability. However, issues remain with regard to cytochrome P450 drug-related interactions and the need for therapeutic drug monitoring (e.g., drug concentrations, epoxide metabolite concentrations, hematology, and liver function tests) as part of the treatment and monitoring process. We review the current body of literature describing the use of carbamazepine in bipolar disorder during both the acute and maintenance phases of the disorder, including trials of both monotherapy and combination therapy, as well as findings from trials that included patients with rapid cycling and mixed episodes.

Abstract
OBJECTIVES The Diagnostic and Statistical Manual of Mental Disorders guidelines provide only a partial solution to the nosology and treatment of bipolar disorder in that disorders with common symptoms and biological correlates may be categorized separately because of superficial differences related to behavior, life history, and temperament. The relationship is explored between extremely rapid switching forms of bipolar disorder, in which manic and depressive symptoms are either mixed or switch rapidly, and forms of borderline personality disorder in which affective lability is a prominent symptom. METHODS A MedLine search was conducted of articles that focused on rapid cycling in bipolar disorder, emphasizing recent publications (2001-2004). RESULTS Studies examined here suggest a number of points of phenomenological and biological overlap between the affective lability criterion of borderline personality disorder and the extremely rapid cycling bipolar disorders. We propose a model for the development of 'borderline' behaviors on the basis of unstable mood states that sheds light on how the psychological and somatic interventions may be aimed at 'breaking the cycle' of borderline personality disorder development. A review of pharmacologic studies suggests that anticonvulsants may have similar stabilizing effects in both borderline personality disorder and rapid cycling bipolar disorder. CONCLUSIONS The same mechanism may drive both the rapid mood switching in some forms of bipolar disorder and the affective instability of borderline personality disorder and may even be rooted in the same genetic etiology. While continued clinical investigation of the use of anticonvulsants in borderline personality disorder is needed, anticonvulsants may be useful in the treatment of this condition, combined with appropriate psychotherapy.

Abstract
Two recently completed large, randomised, double-blind, placebo-controlled trials supporting the efficacy of carbamazepine (CBZ) extended-release capsules (ERC) for the treatment of acute manic and mixed episodes have resulted in US FDA approval of CBZ-ERC, and have reinvigorated the importance of understanding the role of CBZ in bipolar disorder (BD) pharmacotherapy. Additional data suggest that CBZ may have a use in BD maintenance treatment and possibly in acute BD depression. Optimal use of CBZ requires sound knowledge of adverse effects and pharmacokinetic interactions with this agent. Adverse effects commonly involve benign side effects but can rarely include serious haematological, dermatological and hepatic manifestations. On the other hand, metabolic adverse effects (thyroid, glucose, lipid disturbances and significant weight gain) can be less problematic with CBZ, compared with lithium, valproate and atypical antipsychotics. Pharmacokinetic considerations (cytochrome P450 3A3/4 metabolism, active epoxide metabolite and catabolic enzyme induction) can influence the clinical use of CBZ. Managing adverse effects and pharmacokinetic complexities is important for optimising pharmacotherapy with CBZ in patients with BD. This paper reviews the chemistry, pharmacodynamics and pharmacokinetics of CBZ, as well as reviews of the controlled trials of CBZ in acute bipolar mania, acute bipolar depression and bipolar maintenance treatment.

Abstract
As with the two preceding guidelines of this series, these practice guidelines for the pharmacological maintenance treatment of bipolar disorder were developed by an international task force of the World Federation of Societies of Biological Psychiatry (WFSBP). Their purpose is to supply a systematic overview of all scientific evidence relating to maintenance treatment. The data used for these guidelines were extracted from a MEDLINE and EMBASE search, from recent proceedings from key conferences and various national and international treatment guidelines. The scientific justification of support for particular treatments was categorised into four levels of evidence (A-D). As these guidelines are intended for clinical use, the scientific evidence was not only graded, but also reviewed by the experts of the task force to ensure practicality.

Abstract
OBJECTIVE To compare responses to long-term treatment of rapid-cycling (RC) vs. non-RC bipolar disorder patients and assess relative effectiveness of specific agents in RC patients. METHOD Studies identified by literature searching were analyzed for effects of RC status and treatment-type on clinical outcome (recurrence or non-improvement per exposure-time), using random-effects methods to estimate pooled rates and their 95% CI for quantitative meta-analytic modeling. RESULTS Data were obtained from 16 reports with 25 trial-arms involving 1856 (905 RC and 951 non-RC) patients treated with carbamazepine, lamotrigine, lithium, topiramate, or valproate, alone or with other agents over an average of 47.5 months (7347 total patient-years). Estimated RC prevalence was 15.4%. Crude rates (%/month) of recurrence (2.31/1.20) and clinical non-improvement (1.93/0.49) averaged 2.9-fold greater in RC vs. non-RC subjects. The pooled RC/non-RC risk ratio (RR) for inferior treatment-response (in 13 direct comparisons) was 1.40 (CI 1.26-1.56; P < 0.0001). Pooled crude recurrence and non-improvement rates suggested no clear advantage for any treatment, nor superiority for anticonvulsants over lithium. However, only lithium vs. carbamazepine could be directly compared (in four treatment-arms) meta-analytically in RC patients (RR = 0.93, CI 0.74-1.18, indicating no difference in effectiveness). CONCLUSION As expected, RC was associated with lower effectiveness of all treatments evaluated. Direct comparisons of specific treatment alternatives for RC patients were rare, and provided no secure evidence of superiority of any treatment. Additional long-term studies comparing RC/non-RC patients randomized to specific treatments are required.

Abstract
Recent evidence suggests that lithium therapy (even as supplemented by antidepressants and neuroleptics) is inadequate for the majority of patients with bipolar illness, and particularly those with rapid cycling. Valproate and carbamazepine have emerged as adjuncts and alternatives, but they, too, often require additional approaches with lithium, thyroid hormones, and other putative mood stabilizers, including nimodipine (and related dihydropyridine calcium channel blockers), lamotrigine, gabapentin, topiramate, and the atypical neuroleptics. Evaluating how these agents and the unimodal antidepressants are optimally applied and sequenced in the treatment of bipolar illness with its multiple subtypes, patterns and comorbidities will require much future investigation and the development of new methodological clinical trial approaches.

Abstract
While lithium is an effective mood stabiliser still in widespread clinical use, a significant proportion of patients either respond poorly or are unable to tolerate its adverse effects. In the 1960s and 1970s preliminary reports of the possible effectiveness of carbamazepine and valproate began to appear, with confirmatory controlled studies being undertaken in the 1980s and 1990s. In recent years, further putative mood-stabilising agents have been described, in particular some of the newer anticonvulsants and the atypical antipsychotics. This paper critically evaluates the current evidential basis for claims for the efficacy of these compounds in bipolar disorder.

Abstract
Lithium has been the drug of choice in treating bipolar disorder for 50 years and, therefore, patterns of response associated with its use define what we expect from treatment. Although efforts to establish some other agents as antimanic have been successful, it is difficult to assess their overall efficacy in relation to that of lithium without a better understanding of inclusion/exclusion criteria, subtypes, definitions of remission, relapse and recurrence, and duration of study. All of these factors need to be carefully addressed to identify the most important clinical targets for new drug development. Additional relevant information emerges from studies on combinations of mood stabilisers, efficacy of antimanic agents in different patient populations, analysis of rates of drop-out, non-compliance, suicide, drug abuse, and discontinuation especially with long-term treatment. Agents other than lithium that are effective in the acute phase treatment are still not well characterised as mood stabilisers. New agents need to be evaluated in the context of long-term treatment and the targeting of specific components of the syndrome beyond mania.

Abstract
Rapid cycling bipolar affective disorder has attracted renewed interest in the general adult psychiatric literature, particularly as the response to lithium prophylaxis is poor in this subgroup of patients. The present paper describes a systematic Medline/Psyclit review of case studies and small series of patients with rapid cycling bipolar affective disorder in people with intellectual disability (ID). Rapid cycling bipolar affective disorder in people with ID may differ from its occurrence in the non-ID population in terms of a relative preponderance of males, an increased likelihood of rapid cycling onset in those with an early (prepubertal) onset of affective disorder and a different response to prophylactic drugs. The efficacy of treatment and prophylaxis of rapid cycling illnesses needs further investigation in the population with ID.

Abstract
Although many studies of RCBD have been reported over the last 2 decades, knowledge remains limited. Higher incidence in women is the sole clearly replicated finding in most studies. This finding might be mediated by cyclothymia, a temperament that is of higher prevalence in women and that might be considered as a normal variant of RC. Many questions remain unanswered. Review of putative risk factors, such as hypothyroidism and treatment with antidepressants, provides no conclusive answers. There is clinical evidence to implicate both factors. In principle, the thyroid connection can be approached rationally, yet there seems to be no relationship between thyroid status and response to thyroid augmentation. For this reason and given the potential risks of long-term thyroid use, this strategy should not be the first one to be tried in RC. Cumulatively, naturalistic studies over the past 30 years have strongly implicated antidepressants in switching and cycle acceleration, yet the double-blind, controlled, prospective studies that are needed to provide definitive answers are unlikely to be conducted for ethical reasons discussed in this article. Bipolar family history of RC probands appears indistinguishable from non-RC probands, indicating that most likely RCBD does not breed true. Although RC seems to be more lithium resistant with less likelihood of being symptom-free after 2 to 5 years of follow-up, many of these patients nonetheless have resolution of the RC course. There is no marked difference in suicide rates. An association of RC with bipolar type II, D-M-I pattern and those who switch into mania or hypomania on antidepressants is a provocative possibility: Antidepressants might introduce RC by first inducing a switch during a depressive episode, creating a D-M-I pattern, a pattern that is poorly responsive to lithium, which eventually degenerates into RC. Again, this sequence might be mediated by the high prevalence of cyclothymia in bipolar II patients. Thus, data from phenomenology, family history, and long-term outcome do not support RC as a separate entity. RC appears to be a temporary complicated phase in the illness, not a stable feature. This was noted by Kraepelin: I think I am convinced that that kind of classification must of necessity wreck on the irregularity of the disease. The kind and duration of the attacks and the intervals by no means remain the same in the individual case but may frequently change, so that the case must be reckoned always to new forms. Data by Gottschalk et al testify to the chaotic mood swings of contemporary bipolar disorder. Moreover RC is seen in other medical diseases, such as epilepsy, in which patients have phases of increase in frequency of episodes (seizures) that become refractory to treatment. Further longitudinal prospective studies are required to understand the complexity of this intriguing phenomenon and to provide better treatments. Algorithms deriving from tertiary research or university-based clinical experience may not generalize to RC or otherwise treatment-resistant bipolar patients seen in more routine practice. Illness severity in RCBD generally precludes double-blind controlled investigations. Meanwhile, clinicians may rely on discontinuing antidepressants, maintaining patients on combined mood stabilizers--of which valproate is probably the most useful--and making judicious use of atypical neuroleptics. Benzodiazepines and alcohol (which produce withdrawal), caffeine, stimulants, exposure to bright light, and sleep deprivation during excited phases should be avoided. Thyroid and nimodipine augmentation can be considered in those with the most malignant course. These are patients who need the maximal support that their psychiatrist can provide them. Office visits must be arranged as the last appointment of the day.

Abstract
Standard pharmacotherapy for the maintenance treatment of patients with bipolar I disorder consists of lithium, valproate, or carbamazepine. However, many patients fail to respond to monotherapy with any of these agents, and as a result, psychiatrists often resort to polypharmacy. Findings from some open-label trials and retrospective chart reviews suggest this approach may be useful, but in the few controlled trials that have been conducted, the results have been negative. One drug combination that warrants further study as maintenance therapy is lithium plus valproate. Each is approved by the U.S. Food and Drug Administration for treatment of acute mania, and lithium has demonstrated efficacy for maintenance treatment as well. Some preliminary evidence suggests that the combination can be effective for patients who do not respond to monotherapy, and it seems to be no more dangerous than monotherapy. Concomitant administration of lithium plus valproate does not significantly alter lithium pharmacokinetics, and statistically significant changes that arise in valproate pharmacokinetics are not clinically significant. Although it is not known whether the drugs interact to augment response, many of their effects in the central nervous system do differ, and there is no indication of pharmacodynamic interactions that oppose each other. Finally, some evidence suggests that lithium and valproate may differ with regard to clinical variables that predict response to treatment.

Abstract
Rapid cycling is a relatively unusual presentation of bipolar affective disorder in the elderly. Four cases or rapid-cycling affective disorder (RCAD) in elderly women (aged 78-86 yr) are presented. Two patients began their bipolar illness in adulthood (aged 30 and 49 yr), and rapid cycles appeared secondarily in their elderly years (82 and 76 yr). The other two began their illness immediately with rapid cycles respectively at the age of 62 and 66. Added to the nine cases of RCAD in the elderly previously reported in the literature, a meta-analysis conducted on this small sample suggests that immediate entry in rapid cycles seems more likely to be associated with a late occurrence of bipolar illness (after 60 years of age)(P = .0035, Fisher's Exact Test, two-tailed), and that very short cycles (< 2 weeks each) are more likely to be associated with female gender (P = .0047, Fisher's Exact Test, two-tailed). Despite the small size of the sample, these results give some arguments to the hypothesis that RCAD is not a homogeneous syndrome but could be considered as a pattern of evolution, as well as clinical subtype, of the bipolar illness.

Abstract
Although lithium remains the preferred treatment of bipolar disorder, only 60 to 80% of patients with the classic presentation have an adequate response to this drug. When the response rate to lithium is considered across the entire spectrum of bipolar disorders, this rate probably decreases to 50%. Natural history, illness subtype, and comorbidity are all important general predictors of response to treatment. At present, the only predictors that seem to differentially favor divalproex, and possible, carbamazepine over lithium are mixed states and rapid cycling. An overview of clinical presentations that predict general and differential response to mood stabilizers is provided.

Non-lithium pharmacological treatment of manic depression: a review. Ir J Psychol Med 1993.

Abstract
AbstractObjectives:To examine the reasons why manic-depressive patients often fail to respond to lithium and, the chief purpose of this paper, to review the present state of knowledge concerning alternative pharmacotherapies to lithium in this disorder.Method:Literature review.Findings:Lithium produces a clinically useful effect in 70-80% of cases. Factors such as non-compliance, side-effects, serum levels, and enduring psychosocial influences on the patient must be considered before treatment failure is diagnosed. Carbamazepine is the most studied alternative drug to date, and the most likely predictors of response to this agent are rapid-cycling, absence of a family history of affective disorder, mania, severe illness, and non-response to lithium.Conclusions:In view of the 20-25% of patients who do not respond to lithium, and the increased likelihood that lithium-responders may fail to respond again once the drug has been stopped for a period, further research is needed to find better and safer prophylactics against depression in bipolar disorders and to refine our knowledge of the indications for use of those already available.
