Abstract
The term older-age bipolar disorder (OABD) refers to patients with bipolar disorder who are ages 50 and older. Research findings suggest important differences, including the attenuation of manic symptoms with age and the occurrence of multiple somatic comorbid conditions. Although the pharmacological treatment of OABD is fairly similar, adverse effects, somatic comorbidity, and drug-drug interactions are more common. Lithium is effective in treating OABD and may have the potential to be neuroprotective. Anticonvulsants and second-generation antipsychotics have a growing evidence supporting their use in treating OABD. Behavioral intervention can be a helpful adjunct to pharmacological treatment. Clinicians and health care systems need to be prepared to provide care and services to individuals with bipolar disorder throughout the life span. Although older adults have typically been excluded from bipolar disorder RCTs, emerging efforts organized by global advocates and harnessing teams of clinicians and scientists have the potential to advance care.

Therapeutic Potential and Limitation of Serotonin Type 7 Receptor Modulation. Int J Mol Sci 2023; 24:ijms24032070. [PMID: 36768393 PMCID: PMC9916679 DOI: 10.3390/ijms24032070] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2023] [Revised: 01/15/2023] [Accepted: 01/18/2023] [Indexed: 01/21/2023] Open
Abstract
Although a number of mood-stabilising atypical antipsychotics and antidepressants modulate serotonin type 7 receptor (5-HT7), the detailed contributions of 5-HT7 function to clinical efficacy and pathophysiology have not been fully understood. The mood-stabilising antipsychotic agent, lurasidone, and the serotonin partial agonist reuptake inhibitor, vortioxetine, exhibit higher binding affinity to 5-HT7 than other conventional antipsychotics and antidepressants. To date, the initially expected rapid onset of antidepressant effects-in comparison with conventional antidepressants or mood-stabilising antipsychotics-due to 5-HT7 inhibition has not been observed with lurasidone and vortioxetine; however, several clinical studies suggest that 5-HT7 inhibition likely contributes to quality of life of patients with schizophrenia and mood disorders via the improvement of cognition. Furthermore, recent preclinical studies reported that 5-HT7 inhibition might mitigate antipsychotic-induced weight gain and metabolic complication by blocking other monoamine receptors. Further preclinical studies for the development of 5-HT7 modulation against neurodevelopmental disorders and neurodegenerative diseases have been ongoing. To date, various findings from various preclinical studies indicate the possibility that 5-HT7 modifications can provide two independent strategies. The first is that 5-HT7 inhibition ameliorates the dysfunction of inter-neuronal transmission in mature networks. The other is that activation of 5-HT7 can improve transmission dysfunction due to microstructure abnormality in the neurotransmission network-which could be unaffected by conventional therapeutic agents-via modulating intracellular signalling during the neurodevelopmental stage or via loss of neural networks with aging. This review attempts to describe the current and novel clinical applications of 5-HT7 modulation based on preclinical findings.

Efficacy and safety of adjunctive therapy to lamotrigine, lithium, or valproate monotherapy in bipolar depression: a systematic review and meta-analysis of randomized controlled trials. Int J Bipolar Disord 2022; 10:24. [PMID: 36269465 DOI: 10.1186/s40345-022-00271-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/23/2022] [Accepted: 09/16/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The efficacy and safety of adjunctive therapy are unclear in bipolar depression. In this systematic review and meta-analysis, we aimed to evaluate the efficacy and safety of second-generation antipsychotic, lamotrigine, lithium, or valproate therapy used in adjunction with lamotrigine, lithium, or valproate monotherapy in bipolar depression. A literature search of major electronic databases was conducted in February 2021, and all articles published until then were eligible. Two researchers independently screened relevant publications, extracted data, and evaluated methodological quality according to the Cochrane criteria. RESULTS Five studies met the inclusion criteria. The meta-analysis revealed significant differences in the following outcomes: (i) remission rates from depressive episodes (risk ratio [RR]: 1.23, 95% confidence interval [CI] 1.01-1.50, p = 0.04), (ii) improvement in depressive symptoms (standardized mean difference [SMD]: 0.21, 95% CI 0.09-0.34, p = 0.001), (iii) improvement in quality of life (SMD: 0.22, 95% CI 0.06-0.37, p = 0.005), and (iv) rate of adverse events during the study period (RR: 1.12, 95% CI 1.03-1.22, p = 0.008). There was no significant difference between adjunctive therapy and monotherapy in the emergence of suicide-related behaviors, dropout rate during the study period, or rate of manic switching. CONCLUSIONS Our results suggest that adjunctive second-generation antipsychotics, lamotrigine, lithium, or valproate increase both the benefits and risks in patients with bipolar depression, although there is no significant difference in severe adverse events. Adjunctive therapy should be provided through shared decision-making while considering the patients' condition in clinical settings.

Abstract
BACKGROUND Old age bipolar disorder has been an orphan of psychiatric research for a long time despite the fact that bipolar disorder (BD)-I and II together may affect 0.5-1.0% of the elderly. It is also unclear whether aetiology, course of illness and treatment should differ in patients with a first manifestation in older age and patients suffering from a recurrence of a BD known for decades. This narrative review will summarize the current state of knowledge about the epidemiology, clinical features, and treatment of BD in the elderly. METHODS We conducted a Medline literature search from 1970 to 2021 using MeSH terms "Bipolar Disorder" × "Aged" or "Geriatric" or "Elderly". Search results were complemented by additional literature retrieved from examining cross references and by hand search in text books. Varying cut-off ages have been applied to differentiate old age from adult age BD. Within old age BD, there is a reasonable agreement of distinct entities, early and late-onset BD. They differ to some extent in clinical symptoms, course of illness, and some co-morbidities. Point prevalence of BD in older adults appears slightly lower than in working-age adults, with polarity of episodes shifting towards depression. Psychopharmacological treatment needs to take into account the special aspects of somatic gerontology and the age-related change of pharmacokinetic and pharmacodynamic characteristics. The evidence for commonly used treatments such as lithium, mood-stabilizing antiepileptics, antipsychotics, and antidepressants remains sparse. Preliminary results support a role of ECT as well as psychotherapy and psychosocial interventions in old age BD. CONCLUSIONS There is an obvious need of further research for all treatment modalities of BD in old age. The focus should be pharmacological and psychosocial approaches, as well as their combination, and the role of physical treatment modalities such as ECT.

Abstract
Approximately 25% of all adults with bipolar disorder are over the age of 65. Literature in older age bipolar disorder is sparse and typically extrapolated from data in younger adults. This retrospective cohort study included patients 65-89 years of age with bipolar I or II disorder who were prescribed lithium or SGA treatment. Primary efficacy outcome was defined as time to discontinuation of treatment and numerous secondary safety outcomes were included such as adverse effects; lab changes; mental health related hospitalizations; and death. No difference was found between the lithium group and the SGA group in days until discontinuation.

Abstract
Data regarding older age bipolar disorder (OABD) are sparse. Two major groups are classified as patients with first occurrence of mania in old age, the so called “late onset” patients (LOBD), and the elder patients with a long-standing clinical history, the so called “early onset” patients (EOBD). The aim of the present literature review is to provide more information on specific issues concerning OABD, such as epidemiology, aetiology and treatments outcomes. We conducted a Medline literature search from 1970–2021 using the MeSH terms “bipolar disorder” and “aged” or “geriatric” or “elderly”. The additional literature was retrieved by examining cross references and by a hand search in textbooks. With sparse data on the treatment of OABD, current guidelines concluded that first-line treatment of OABD should be similar to that for working-age bipolar disorder, with specific attention to side effects, somatic comorbidities and specific risks of OABD. With constant monitoring and awareness of the possible toxic drug interactions, lithium is a safe drug for OABD patients, both in mania and maintenance. Lamotrigine and lurasidone could be considered in bipolar depression. Mood stabilizers, rather than second generation antipsychotics, are the treatment of choice for maintenance. If medication fails, electroconvulsive therapy is recommended for mania, mixed states and depression, and can also be offered for continuation and maintenance treatment. Preliminary results also support a role of psychotherapy and psychosocial interventions in old age BD. The recommended treatments for OABD include lithium and antiepileptics such as valproic acid and lamotrigine, and lurasidone for bipolar depression, although the evidence is still weak. Combined psychosocial and pharmacological treatments also appear to be a treatment of choice for OABD. More research is needed on the optimal pharmacological and psychosocial approaches to OABD, as well as their combination and ranking in an evidence-based therapy algorithm.

Abstract
Objectives This narrative review aims to synthesize information from the literature regarding older-age bipolar disorder (OABD) in order to provide up-to-date information on this important illness. Methods We searched Ovid (Medline, Embase and PsychInfo) on October 1, 2020, using the keywords “bipolar disorder”, “older adults” and “elderly” to identify relevant articles on OABD. Additionally, the bibliography of identified articles was reviewed for pertinent studies. Discussions OABD is a term that is used to describe bipolar disorder (BD) occurring amongst individuals ≥50 years of age. Evidence indicates that OABD accounts for a quarter of all cases of BD. When compared to individuals with early-onset BD, individuals with OABD have a greater association with cerebrovascular disease and other neurological disorders, less family history of mood disorders, and utilize almost four times the total amount of mental health services. In addition, they are four times more likely to have psychiatric hospitalizations when compared to age-matched controls. Despite a dearth of controlled studies on the use of pharmacotherapy amongst individuals with OABD, available evidence from mixed-age studies indicates the efficacy of commonly used medications in individuals with early-onset BD. Additionally, psychosocial treatments have been found to be effective as adjunctive management strategies amongst individuals with OABD. Furthermore, electroconvulsive therapy may be effective in the treatment of refractory cases of OABD. Conclusions There is a great need for an improved understanding of the phenomenology and neurobiology of OABD. Additionally, research into effective treatments for this serious psychiatric disorder will mitigate the suffering of individuals with OABD.

Abstract
INTRODUCTION Research into the pharmacologic management of bipolar type I illness continues to progress. AREAS COVERED Randomized clinical trials performed with type I bipolar disorder in the years 2015 to August 2020 are reviewed. There are new indications for the use of cariprazine, for bipolar mania and depression, and a long-acting injectable formulation of aripiprazole has also been approved for relapse prevention in bipolar illness. Most of the randomized clinical trials are effectiveness studies. EXPERT OPINION Over the 20 years from 1997 through 2016, the use of lithium and other mood stabilizers has declined by 50%, while the use of both second-generation antipsychotics (SGAs) and antidepressants has increased considerably. Over the same time period (1990-2017), disability-adjusted life years (DALYs) increased by 54.4%, from 6.02 million in 1990 to 9.29 million in 2017 which is greater than the 47.74% increase in incidence of the disease, suggesting that the changes in prescribing patterns have not been helpful for our patients. Furthermore, recent effectiveness studies continue to confirm the superiority of lithium and other mood stabilizers in the management of bipolar illness for both psychiatric and medical outcomes, reaffirming their role as foundational treatments in the management of type I bipolar disorder. Clinicians need to reassess their prescribing habits.

Effects of Subchronic Administrations of Vortioxetine, Lurasidone, and Escitalopram on Thalamocortical Glutamatergic Transmission Associated with Serotonin 5-HT7 Receptor. Int J Mol Sci 2021; 22:ijms22031351. [PMID: 33572981 PMCID: PMC7866391 DOI: 10.3390/ijms22031351] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2020] [Revised: 01/22/2021] [Accepted: 01/27/2021] [Indexed: 02/06/2023] Open
Abstract
The functional suppression of serotonin (5-HT) type 7 receptor (5-HT7R) is forming a basis for scientific discussion in psychopharmacology due to its rapid-acting antidepressant-like action. A novel mood-stabilizing atypical antipsychotic agent, lurasidone, exhibits a unique receptor-binding profile, including a high affinity for 5-HT7R antagonism. A member of a novel class of antidepressants, vortioxetine, which is a serotonin partial agonist reuptake inhibitor (SPARI), also exhibits a higher affinity for serotonin transporter, serotonin receptors type 1A (5-HT1AR) and type 3 (5-HT3R), and 5-HT7R. However, the effects of chronic administration of lurasidone, vortioxetine, and the selective serotonin reuptake inhibitor (SSRI), escitalopram, on 5-HT7R function remained to be clarified. Thus, to explore the mechanisms underlying the clinical effects of vortioxetine, escitalopram, and lurasidone, the present study determined the effects of these agents on thalamocortical glutamatergic transmission, which contributes to emotional/mood perception, using multiprobe microdialysis and 5-HT7R expression using capillary immunoblotting. Acute local administration of a 5-HT7R agonist and antagonist into the mediodorsal thalamic nucleus (MDTN) enhanced and reduced thalamocortical glutamatergic transmission, induced by N-methyl-D-aspartate (NMDA)/glutamate receptor inhibition in the reticular thalamic nucleus (RTN). Acute local administration of a relevant therapeutic concentration of vortioxetine and lurasidone into the MDTN suppressed the thalamocortical glutamatergic transmission via 5-HT7R inhibition, whereas that of escitalopram activated 5-HT7R. Subchronic administration of effective doses of vortioxetine and lurasidone (for 7 days) reduced the thalamocortical glutamatergic transmission, but escitalopram did not affect it, whereas subchronic administration of these three agents attenuated the stimulatory effects of the 5-HT7R agonist on thalamocortical glutamatergic transmission. Subchronic administration of effective doses of vortioxetine, lurasidone, and escitalopram downregulated the 5-HT7R expression of the plasma membrane in the MDTN; the 5-HT7R downregulation induced by vortioxetine and lurasidone was observed at 3 days, but that induced by escitalopram required a longer duration of 7 days. These results indicate that chronic administration of vortioxetine, escitalopram, and lurasidone generate downregulation of 5-HT7R in the thalamus; however, the direct inhibition of 5-HT7R associated with vortioxetine and lurasidone generates more rapid downregulation than the indirect elevation of the extracellular serotonin level via serotonin transporter inhibition by escitalopram.

Abstract
PURPOSE OF REVIEW With more individuals reaching older ages, bipolar disorder is no longer a rare illness in the elderly. Despite the growing number of the older individuals with the illness, there are few studies that focus on bipolar disorder in the geriatric population leading to gaps in clinical knowledge and treatment. The aim of this study is therefore to increase understanding by summarizing the available literature on the epidemiology, symptomatology, comorbidities, and treatment recommendations in this cohort, as well as to suggest areas for future clinical and research focus. RECENT FINDINGS The prevalence of bipolar disorder is underestimated in the geriatric population. The illness maintains the main features observed in the other cohorts but it also has some specific characteristics in the older individuals. In this cohort, psychiatric and medical comorbidities tend to be the rule rather than the exception. Higher rates of cognitive impairments than age- and education-matched groups present across all of the illness phases. Treatment is more challenging in the elderly individuals due to higher rates of comorbidities and susceptibility to medication side effects. Two cohorts of older individuals with bipolar disorder can be recognized, those with symptoms that start earlier in life and those with late-life onset. Although the knowledge about elderly bipolar disorder is only slowly growing, it is increasingly recognized as an illness with unique features. More work is needed to improve diagnosis and to establish treatment guidelines.

Abstract
Several mood-stabilizing atypical antipsychotics and antidepressants weakly block serotonin (5-HT) receptor type-7 (5-HT7R); however, the contributions of 5-HT7R antagonism to clinical efficacy and pathophysiology are yet to be clarified. A novel mood-stabilizing antipsychotic agent, lurasidone exhibits predominant binding affinity to 5-HT7R when compared with other monoamine receptors. To date, we have failed to discover the superior clinical efficacy of lurasidone on schizophrenia, mood, or anxiety disorders when compared with conventional mood-stabilizing atypical antipsychotics; however, numerous preclinical findings have indicated the possible potential of 5-HT7R antagonism against several neuropsychiatric disorders, as well as the generation of novel therapeutic options that could not be expected with conventional atypical antipsychotics. Traditional experimental techniques, electrophysiology, and microdialysis have demonstrated that the effects of 5-HT receptor type-1A (5-HT1AR) and 5-HT7R on neurotransmission are in contrast, but the effect of 5-HT1AR is more predominant than that of 5-HT7R, resulting in an insufficient understanding of the 5-HT7R function in the field of psychopharmacology. Accumulating knowledge regarding the pharmacodynamic profiles of 5-HT7R suggests that 5-HT7R is one of the key players in the establishment and remodeling of neural development and cytoarchitecture during the early developmental stage to the mature brain, and dysfunction or modulation of 5-HT7R is linked to the pathogenesis/pathophysiology of neuropsychiatric and neurodevelopmental disorders. In this review, to explore candidate novel applications for the treatment of several neuropsychiatric disorders, including mood disorders, schizophrenia, and other cognitive disturbance disorders, we discuss perspectives of psychopharmacology regarding the effects of 5-HT7R antagonism on transmission and intracellular signaling systems, based on preclinical findings.

Abstract
Lithium is the gold-standard treatment for bipolar disorder, and is effective in the management of manic, depressive, and maintenance phases of bipolar disorder treatment. Despite this, the implications of lithium use in the older population remain less understood. This critical narrative review aims to better understand the impact of lithium in older age bipolar disorder (OABD), including tolerability and efficacy, based on up-to-date evidence. Relevant studies of efficacy, effectiveness, and tolerability published any time prior to May 2018 were identified using the PubMed keyword search "lithium older adult bipolar disorder" and references from recent international bipolar disorder guidelines. One randomized controlled trial was identified, the GERI-BD (Acute Pharmacotherapy in Late-Life Mania) study. This study found lithium to be effective in late-life mania and hypomania. The remaining literature examining lithium in OABD was reviewed, comprising of a number of small open-label and retrospective studies, with special considerations highlighted. In summary, there is a small yet increasing geriatric evidence base that lithium is effective in OABD. Although there can be adverse effects with lithium, it is generally well tolerated, and there are methods to minimize these risks. Further research would strengthen the evidence base for lithium therapy in OABD. In the meantime, lithium remains the gold-standard treatment for OABD.

Abstract
Bipolar disorder prevalence rates vary in the older adult population (defined as age ≥ 65 years), ranging from 1% in community dwellers to as high as 8-10% in hospital inpatients. Although older agents, including lithium and valproic acid, offer significant antimanic efficacy, as supported by a recent randomized controlled trial (RCT), there is growing interest in using atypical antipsychotics to treat bipolar disorder in older adults. Newer atypical antipsychotics are of interest based on their tolerability and efficacy in the general adult bipolar population. The aim of this review was to systematically examine efficacy and tolerability of newer atypical antipsychotics for older adult bipolar disorder (OABD). We conducted a systematic search utilizing the MEDLINE, EMBASE, PsycINFO and Cochrane Library electronic databases, with the aim of identifying all RCTs comparing newer atypical antipsychotics approved by the US FDA since 2002 (including brexpiprazole, cariprazine, lurasidone, iloperidone, asenapine, paliperidone, and aripiprazole) with placebo or another comparator, in the treatment of any phase of bipolar disorder (including mania, depression or mixed episodes while used as an acute or maintenance treatment) in older adults (> 65 years). We found no RCT data on any of the examined agents. Hence, we changed our search criteria to include studies with a lower age cut-off (≥ 55 years), as well as the inclusion of post hoc studies. Two post hoc studies on lurasidone suggest its reasonable safety and efficacy profile in the acute and maintenance treatment of OABD; however, there are no pharmacoeconomic data on the use of lurasidone in the treatment of OABD. Research data from open-label studies on oral asenapine and aripiprazole as add-on therapy suggest that these two agents are adequately tolerated and improved symptoms of depression and mania in OABD; hence, there is an urgent need to conduct RCTs on these two agents. Lastly, we found no studies for the treatment of OABD with brexpiprazole, cariprazine, iloperidone, or paliperidone.

Abstract
The Canadian Network for Mood and Anxiety Treatments (CANMAT) previously published treatment guidelines for bipolar disorder in 2005, along with international commentaries and subsequent updates in 2007, 2009, and 2013. The last two updates were published in collaboration with the International Society for Bipolar Disorders (ISBD). These 2018 CANMAT and ISBD Bipolar Treatment Guidelines represent the significant advances in the field since the last full edition was published in 2005, including updates to diagnosis and management as well as new research into pharmacological and psychological treatments. These advances have been translated into clear and easy to use recommendations for first, second, and third- line treatments, with consideration given to levels of evidence for efficacy, clinical support based on experience, and consensus ratings of safety, tolerability, and treatment-emergent switch risk. New to these guidelines, hierarchical rankings were created for first and second- line treatments recommended for acute mania, acute depression, and maintenance treatment in bipolar I disorder. Created by considering the impact of each treatment across all phases of illness, this hierarchy will further assist clinicians in making evidence-based treatment decisions. Lithium, quetiapine, divalproex, asenapine, aripiprazole, paliperidone, risperidone, and cariprazine alone or in combination are recommended as first-line treatments for acute mania. First-line options for bipolar I depression include quetiapine, lurasidone plus lithium or divalproex, lithium, lamotrigine, lurasidone, or adjunctive lamotrigine. While medications that have been shown to be effective for the acute phase should generally be continued for the maintenance phase in bipolar I disorder, there are some exceptions (such as with antidepressants); and available data suggest that lithium, quetiapine, divalproex, lamotrigine, asenapine, and aripiprazole monotherapy or combination treatments should be considered first-line for those initiating or switching treatment during the maintenance phase. In addition to addressing issues in bipolar I disorder, these guidelines also provide an overview of, and recommendations for, clinical management of bipolar II disorder, as well as advice on specific populations, such as women at various stages of the reproductive cycle, children and adolescents, and older adults. There are also discussions on the impact of specific psychiatric and medical comorbidities such as substance use, anxiety, and metabolic disorders. Finally, an overview of issues related to safety and monitoring is provided. The CANMAT and ISBD groups hope that these guidelines become a valuable tool for practitioners across the globe.

Abstract
OBJECTIVE To evaluate the safety and effectiveness of 6 months of treatment with lurasidone in older adults with a diagnosis of bipolar I depression. DESIGN Post-hoc analysis of a multicenter, 6-month, open-label extension study. SETTING Outpatient. PARTICIPANTS Patients aged 55 to 75 years with a DSM-IV-TR diagnosis of bipolar I depression who had completed 6 weeks of double-blind, placebo-controlled treatment with either lurasidone monotherapy (1 study) or adjunctive therapy with lithium or valproate (2 studies). INTERVENTION Flexible doses of lurasidone, 20 to 120 mg/day, either as monotherapy, or adjunctive with lithium or valproate. MEASUREMENTS Effectiveness was assessed using the Montgomery-Åsberg Depression Rating Scale (MADRS; change from open-label-baseline to month-6, observed case analysis). RESULTS A total of 141 older adults entered the extension study (monotherapy, N = 55; 39%; adjunctive therapy, N = 86; 61%). At the end of 6 months of open-label treatment with lurasidone, as monotherapy or adjunctive therapy, minimal changes were observed in the older adult sample in mean weight (-1.0 kg and -0.4 kg, respectively); and median total cholesterol (-2.0 mg/dL and +6.0 md/dL, respectively), triglycerides (+2.5 mg/dL and +6.0 mg/dL, respectively), and HbA1c (0.0% and -0.1%, respectively). Patients treated with 6 months of lurasidone showed a mean improvement on the MADRS in both the monotherapy (-6.2) and adjunctive therapy (-6.7) groups. CONCLUSIONS Results of these post-hoc analyses found that up to 7.5 months of lurasidone treatment for bipolar depression in older adults was associated with minimal effects on weight and metabolic parameters, with low rates of switching to hypomania or mania, and was well tolerated. The antidepressant effectiveness of lurasidone in this age group was maintained over the 6-month treatment period.

Abstract
INTRODUCTION Lurasidone ([3aR,4S,7R,7aS]-2-[(1R,2R)-2-[4-(1,2-benzisothiazol-3-yl)piperazin-1yl-methyl] cyclohexylmethyl]-hexahydro-4,7-methano-2H-isoindole-1,3-dione hydrochloride; Latuda®) is a novel benzisothiazole, second-generation antipsychotic drug developed by Dainippon Sumitomo Pharma Corporation in Japan. Similar to other atypical antipsychotics it has a distinctive pharmacodynamic profile, Areas covered: This review updates reported research findings on the efficacy, safety and tolerability of LRSD for treatment of psychotic and major affective disorders, with meta-analyses. Short-term efficacy of LRSD in schizophrenia is supported by several randomized, controlled trials with daily doses of 40-160 mg, yielding relatively modest symptomatic improvements. Lurasidone has regulatory approval for treatment of undefined duration in schizophrenia. Long-term benefits and effects in schizophrenia, and both short- and long-term use for other psychotic disorders and mania have not been tested. LRSD shows unusual efficacy in acute bipolar depression even without psychotic features. However, trials of adding LRSD to lithium or valproate for bipolar disorder have yielded inconsistent findings. Expert opinion: Available research findings indicate that LRSD is effective and well-tolerated for short-term treatment of schizophrenia, and for acute bipolar depression. It has low risk of inducing weight-gain, metabolic, or cardiac abnormalities, but its risk of akathisia may exceed that of other modern antipsychotics. Needed is adequate long-term testing in schizophrenia and bipolar disorder and testing for other indications, including against alternative treatments.
