Prevalence and differences in the co-administration of drugs known to interact: an analysis of three distinct and large populations. BMC Med 2024; 22:166. [PMID: 38637816 PMCID: PMC11027217 DOI: 10.1186/s12916-024-03384-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2023] [Accepted: 04/08/2024] [Indexed: 04/20/2024] Open
Abstract
BACKGROUND The co-administration of drugs known to interact greatly impacts morbidity, mortality, and health economics. This study aims to examine the drug-drug interaction (DDI) phenomenon with a large-scale longitudinal analysis of age and gender differences found in drug administration data from three distinct healthcare systems. METHODS This study analyzes drug administrations from population-wide electronic health records in Blumenau (Brazil; 133 K individuals), Catalonia (Spain; 5.5 M individuals), and Indianapolis (USA; 264 K individuals). The stratified prevalences of DDI for multiple severity levels per patient gender and age at the time of administration are computed, and null models are used to estimate the expected impact of polypharmacy on DDI prevalence. Finally, to study actionable strategies to reduce DDI prevalence, alternative polypharmacy regimens using drugs with fewer known interactions are simulated. RESULTS A large prevalence of co-administration of drugs known to interact is found in all populations, affecting 12.51%, 12.12%, and 10.06% of individuals in Blumenau, Indianapolis, and Catalonia, respectively. Despite very different healthcare systems and drug availability, the increasing prevalence of DDI as patients age is very similar across all three populations and is not explained solely by higher co-administration rates in the elderly. In general, the prevalence of DDI is significantly higher in women - with the exception of men over 50 years old in Indianapolis. Finally, we show that using proton pump inhibitor alternatives to omeprazole (the drug involved in more co-administrations in Catalonia and Blumenau), the proportion of patients that are administered known DDI can be reduced by up to 21% in both Blumenau and Catalonia and 2% in Indianapolis. CONCLUSIONS DDI administration has a high incidence in society, regardless of geographic, population, and healthcare management differences. Although DDI prevalence increases with age, our analysis points to a complex phenomenon that is much more prevalent than expected, suggesting comorbidities as key drivers of the increase. Furthermore, the gender differences observed in most age groups across populations are concerning in regard to gender equity in healthcare. Finally, our study exemplifies how electronic health records' analysis can lead to actionable interventions that significantly reduce the administration of known DDI and its associated human and economic costs.

Abstract
BACKGROUND Lithium use seems to be declining in clinical practice. We examined the proportion of adults aged ≥ 50 years dispensed lithium between 2012 and 2021, and investigated the proportion of lithium users dispensed other medications. METHODS We used a 10% random sample data of the Australian Pharmaceutical Benefits Scheme from 2012 to 2021, and limited our analyses to adults aged ≥ 50 years. We retrieved data on lithium, other mood stabilisers, antipsychotics, antidepressants, anxiolytics and hypnotics, and medications for the treatment of other health systems. RESULTS We received 7081939 person-years records (53.2% women). The proportion of participants dispensed lithium decreased with age: 0.4% for those aged 50-59 years to < 0.1% for people aged ≥ 90 years. The dispensing of lithium increased over 10 years for those aged 50-69 and decreased in those older than 80 years. Among people dispensed lithium, nearly 1 in 5 were dispensed another mood stabiliser. Antipsychotics and antidepressants were dispensed to about 60% of participants dispensed lithium, with antidepressants dispensed more frequently to women than men. About 20% of people dispensed lithium were dispensed anxiolytics/hypnotics, more frequently for women than men. Medications to treat diseases of the alimentary, cardiovascular, endocrine and nervous systems were commonly dispensed to those dispensed lithium, as were antibiotics. CONCLUSIONS While the dispensing of lithium increased among young older adults since 2015 when guidelines for the management of mood disorders were published, our findings suggest that lithium may be under-utilised for the management of bipolar disorder in later life.

Abstract
INTRODUCTION Antiseizure medications (ASMs) and antipsychotic drugs are frequently coadministered with the potential for drug-drug interactions. Interactions may either be pharmacokinetic or pharmacodynamic, resulting in a decrease or increase in efficacy and/or an increase or decrease in adverse effects. AREAS COVERED The clinical evidence for pharmacokinetic and pharmacodynamic interactions between ASMs and antipsychotics is reviewed based on the results of a literature search in MEDLINE conducted in April 2023. EXPERT OPINION There is now extensive published evidence for the clinical importance of interactions between ASMs and antipsychotics. Enzyme-inducing ASMs can decrease blood concentrations of many of the antipsychotics. There is also evidence that enzyme-inhibiting ASMs can increase antipsychotic blood concentrations. Similarly, there is limited evidence showing that antipsychotic drugs may affect the blood concentrations of ASMs through pharmacokinetic interactions. There is less available evidence for pharmacodynamic interactions, but these can also be important, as can displacement from protein binding. The lack of published evidence for an interaction should not be interpreted as meaning that the given interaction does not occur; the evidence is building continually. There is no substitute for careful patient monitoring and sound clinical judgment.

Abstract
The co-administration of drugs known to interact has a high impact on morbidity, mortality, and health economics. We study the drug-drug interaction (DDI) phenomenon by analyzing drug administrations from population-wide Electronic Health Records (EHR) in Blumenau (Brazil), Catalonia (Spain), and Indianapolis (USA). Despite very different health care systems and drug availability, we find a common large risk of DDI administration that affected 13 to 20% of patients in these populations. In addition, the increasing risk of DDI as patients age is very similar across all three populations but is not explained solely by higher co-administration rates in the elderly. We also find that women are at higher risk of DDI overall- except for men over 50 years old in Indianapolis. Finally, we show that PPI alternatives to Omeprazole can reduce the number of patients affected by known DDIs by up to 21% in both Blumenau and Catalonia, and 2% in Indianapolis, exemplifying how analysis of EHR data can lead to a significant reduction of DDI and its associated human and economic costs. Although the risk of DDIs increases with age, administration patterns point to a complex phenomenon that cannot be solely explained by polypharmacy and multimorbidity. The lack of safer drug alternatives, particularly for chronic conditions, further overburdens health systems, thus highlighting the need for disruptive drug research.

Abstract
Bipolar disorders (BDs) are a heterogeneous group of severe affective disorders generally described by the alternation of (hypo)manic, depressive, and mixed phases, with euthymic intervals of variable duration. BDs are burdened with high psychiatric and physical comorbidity, increased suicide risk and reduced life expectancy. In addition, BDs can progress into complicated forms (e.g., mixed states, rapid/irregular cycling), which are more difficult to treat and often require personalized pharmacological combinations. Mood stabilizers, particularly Lithium and Valproic acid (VPA), still represent the cornerstones of both acute and chronic pharmacotherapies of BDs. Lithium is the gold standard in BD-I and BDII with typical features, while VPA seems more effective for atypical forms (e.g., mixed-prevalence and rapid-cycling). However, despite appropriate mood stabilization, many patients show residual symptoms, and more than a half recur within 1-2 years, highlighting the need of additional strategies. Among these, the association of atypical antipsychotics (AAPs) with mood stabilizers is recurrent in the treatment of acute phases, but it is also being growingly explored in the maintenance pharmacotherapy. These combinations are clinically more aggressive and often needed in the acute phases, whereas simplifying pharmacotherapies to mood stabilizers only is preferable in the long-term, whenever possible. When mood stabilizers are not enough for maintenance treatment, Quetiapine and, less consistently, Aripiprazole have been proposed as the most advisable adjunctive strategies, for their safety and tolerability profiles. However, in view of the increased risk of serious adverse effects, a careful patient-centered balance between costs and benefits is mandatory.

Abstract
Psychiatric disorder comorbidity in patients with epilepsy (PWE) is very frequent with a mean percentage prevalence of up to 50% and even higher. Such a high frequency suggests that epilepsy and psychiatric disorders might share common pathological pathways. Various aspects contribute in making the matter very complex from a therapeutic point of view. Some antiseizure medications (ASMs), namely valproic acid, carbamazepine, and lamotrigine, have mood-stabilising effects and are routinely used for the treatment of bipolar disorder in patients who do not have epilepsy. Pregabalin and, to a lesser extent, gabapentin, exerts anxiolytic effects. However, several ASMs, in particular levetiracetam, topiramate, and perampanel, may contribute to psychiatric disorders, including depression, aggressive behaviour, and even psychosis. If these ASMs are prescribed, the patient should be monitored closely. A careful selection should be made also with psychotropic drugs. Although most of these can be safely used at therapeutic doses, bupropion, some tricyclic antidepressants, maprotiline, and clozapine may alter seizure threshold and facilitate epileptic seizures. Interactions between ASMs and psychotropic medication may make it difficult to predict individual response. Pharmacokinetic interactions can be assessed with drug monitoring and are consequently much better documented than pharmacodynamic interactions. Another aspect that needs a careful evaluation is patient adherence to treatment. Prevalence of non-adherence in PWE and psychiatric comorbidities is reported to reach values even higher than 70%. A careful evaluation of all these aspects contributes in optimizing therapy with a positive impact on seizure control, psychiatric wellbeing, and quality of life.

Abstract
Therapeutic drug monitoring (TDM) is an effective tool used to improve the pharmacological treatment in clinical practice, especially to detect subtherapeutic drug plasma concentration (Cp) in order to consider a change of dosage during treatment and reach its putative therapeutic range. In this study, we report the Cp values of lithium and valproic acid (VPA), alone and in combination, mostly in bipolar patients admitted to an Italian clinical center of the University of Pisa during the years 2016–2020, which include 12,294 samples of VPA, 7449 of lithium and 1118 of both in combination. Lithium and VPA are the most utilized drugs in treating bipolar disorders, and their TDM is strongly recommended by recent guidelines. In relation to lithium Cp monitoring, several studies have underlined that 0.5–0.8 mmol/L is the optimal range for chronic treatment, and below 0.4 mmol/L, it is unlikely to produce a clinical response. For VPA, the therapeutic range is 50–100 μg/mL and a linear correlation between Cp and clinical efficacy has been proposed, where below 50 μg/mL, the clinical efficacy of VPA has not been proven thus far. Toxic levels of both drugs were rarely found in our study, while a high percentage of patients, about one-third, had sub-therapeutic Cp during their treatments. In addition, in several cases of patients receiving multiple blood sampling, the initial subtherapeutic Cp changed only partially without reaching its therapeutic window. In relation to age, we found a higher percentage of lithium and VPA Cp values in range in the adolescents than in the adults and elderly groups. No differences were reported when analyzing the distribution of Cp values in males and females. In conclusion, this present study suggests that TDM is widely used by many specialists, but there is still a window of improvement for optimizing pharmacological treatments in clinical practice.

Abstract
A trend in the increasing use of prescription psychoactive drugs (PADs), including antidepressants, antipsychotics, and mood stabilizers, has been reported in the United States and globally. In addition, there has been an increase in the production and usage of illicit PADs and emergence of new psychoactive substances (NPSs) all over the world. PADs pose unique challenges for critical care providers who may encounter toxicology issues due to drug interactions, side effects, or drug overdoses. This article provides a summary of the toxicologic features of commonly used and abused PADs: antidepressants, antipsychotics, mood stabilizers, hallucinogens, NPSs, caffeine, nicotine, and cannabis.

Abstract
Psychiatric disorders such as schizophrenia can generate distress and disability along with heavy costs on individuals and health care systems. Different genetic and environmental factors play a pivotal role in the appearance of the mentioned disorders. Since the conventional treatment options for psychiatric disorders are suboptimal, investigators are trying to find novel strategies. Herein, stem cell therapies have been recommended as novel choices. In this context, the preclinical examination of stem cell-based therapies specifically using appropriate models can facilitate passing strong filters and serious examination to ensure proper quality and safety of them as a novel treatment approach. Animal models cannot be adequately helpful to follow pathophysiological features. Nowadays, stem cell-based models, particularly induced pluripotent stem cells reflected as suitable alternative models in this field. Accordingly, the importance of stem cell-based models, especially to experiment with the regenerative medicine outcomes for schizophrenia as one of the severe typing of psychiatric disorders, is addressed here.

Abstract
OBJECTIVES To examine the effectiveness of low-dose lithium carbonate for managing carbamazepine-induced hyponatremia. METHODS Single case study in an 88 year old man with bipolar illness and vascular dementia who had failed to respond to other mood stabilizers. RESULTS The patient had developed hyponatremia on two separate occasions when treated with carbamazepine. Introduction of low-dose lithium resulted in prompt normalization of serum sodium levels, which was maintained for the subsequent 8 weeks. CONCLUSIONS Carbamazepine may sometimes be the best or only viable treatment option for patients with bipolar illness or other conditions. When its use is complicated by syndrome of inappropriate ADH, dose reduction and fluid restriction are the simplest options but, if ineffective, addition of lithium may be a feasible, albeit somewhat complicated, alternative.

OBJECTIVE This cross-sectional study aimed to evaluate the prevalence and factors associated with residual symptoms (both depressive and manic) in subjects with bipolar disorder (BD). MATERIALS AND METHODS A total of 844 subjects diagnosed BD with an illness of 2 years' duration and minimum of two lifetime episodes and in clinical remission were evaluated for residual symptoms using Hamilton Depression Rating Scale (HAM-D) and Young Mania Rating Scale (YMRS). Based on the severity of residual symptoms, the study groups were divided into four groups. RESULTS Sixty-nine percent of the subjects had residual depressive symptoms (i.e., HAM-D score in the range of 1-7) and 59% had residual manic symptoms (i.e., YMRS score in the range of 1-7). The most common residual depressive symptom was psychic anxiety (34%) followed by impaired insight (29%). The most common manic symptom was poor insight (31%) followed by sleep disturbances (25%). Subjects with both sets of residual symptoms had onset of BD at a relatively young age, when compared to those with only residual depressive symptoms. Presence of any comorbid physical illness and substance abuse disorder was significantly higher in those with both sets of residual symptoms. CONCLUSIONS The present study suggests that a substantial proportion of patients with BD have residual symptoms of both types. Comorbid physical illness and substance use were associated with residual symptoms. Identification and management of residual symptoms are highly essential to improve the overall outcome of patients with BD.

Abstract
Mood stabilising therapy is the cornerstone of treatment for bipolar disorder, a disease that is commonly associated with disabling psychosocial morbidity [37,11]. A variety of drugs have been approved for use in bipolar disorder, thus providing a wide array of options for clinicians when deciding on a course of treatment [28]. In order to assist clinical decision-making, facilitate optimal quality of care and reduce unnecessary variation in clinical practice, several clinical practice guidelines and treatment algorithms have been developed [4,19,20,21]. As well as similarities, there are some differences between guidelines developed from an American perspective and those developed from a European perspective [4,19], and there is a pervasive view in the clinical community that treatment of patients with bipolar disorder differs substantially between the United States (US) and Europe. This article discusses what is known about the similarities and differences of treatment practices for bipolar disorder between the US and Europe.

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
OBJECTIVES To evaluate the effectiveness of an algorithm for the treatment of mixed episodes in bipolar disorder (BD) using the medications available under the Unified Health System (Sistema Único de Saúde) in Brazil. METHODS The study included 107 individuals with BD in a current mixed episode, assessed biweekly for the outcomes of response and remission. The subjects were randomly assigned to start treatment with lithium, valproic acid, or carbamazepine, following a clinical protocol at a public outpatient clinic. Eligibility screening instruments, semistructured interview, and clinical psychiatric evaluation were used for diagnosis. To measure response and remission, the Hamilton Rating Scale for Depression and the Young Mania Rating Scale were used. A parameter of 50% or less in the symptom scales was used to define responses, as assessed by Kaplan-Meier time-event analysis. RESULTS For the main outcome, response to treatment, all interventions proposed were proven to be effective, with no difference in response time for any of them. There was a lack of placebo control and blinding for intervention or outcomes. Individuals with mixed episodes in BD often face contradictory symptoms, and these inherent difficulties are the main obstacles to stabilize such a condition. CONCLUSIONS The findings presented in this study show that the treatments available under the Unified Health System are able to reduce the overall burden of disease in terms of symptom reduction.

Abstract
In this paper, the authors review the history of the pharmacological treatment of bipolar disorder, from the first nonspecific sedative agents introduced in the 19th and early 20th century, such as solanaceae alkaloids, bromides and barbiturates, to John Cade's experiments with lithium and the beginning of the so-called "Psychopharmacological Revolution" in the 1950s. We also describe the clinical studies and development processes, enabling the therapeutic introduction of pharmacological agents currently available for the treatment of bipolar disorder in its different phases and manifestations. Those drugs include lithium salts, valproic acid, carbamazepine, new antiepileptic drugs, basically lamotrigine and atypical antipsychotic agents (olanzapine, risperidone, quetiapine, ziprasidone, aripiprazole, asenapine, cariprazine and lurasidone). Finally, the socio-sanitary implications derived from the clinical introduction of these drugs are also discussed.

J Affect Disord 2018; 226:77-84. [PMID: 28964996 DOI: 10.1016/j.jad.2017.09.020] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/12/2017] [Revised: 09/14/2017] [Accepted: 09/18/2017] [Indexed: 12/18/2022]
Abstract
OBJECTIVES To investigate the association between psychotropic agents (including antipsychotics, antidepressants and mood stabilizers) and risk of stroke among patients with bipolar disorders. METHODS We conducted a disease risk score-matched nested case-control study and identified patients with bipolar disorders (ICD-9 codes: 296.0x, 296.1x, 296.4x, 296.5x, 296.6x, 296.7x, 296.80, 296.81 or 296.89) from the National Health Insurance Research Database in Taiwan. Among them, we identified 1232 cases (981 were ischemic stroke and 251 were hemorrhagic stroke) and 5314 disease risk score-matched controls. Conditional logistic regression model equations were applied to determine the effect of psychotropic agents on stroke risk among patients with bipolar disorders. RESULTS The results indicated that overall use of psychotropic agents was associated with an increased risk of stroke (adjusted odds ratio [AOR] = 1.82; 95% confidence interval [CI]: 1.56-2.13). When classifying psychotropic agents into antipsychotics, antidepressants and mood stabilizers, respectively, a significant positive association was found for users of antipsychotics (AOR = 1.98; 95% CI = 1.53-2.56), antidepressants (AOR = 1.44; 95% CI = 1.16-1.79), and mood stabilizers (AOR = 1.89; 95% CI = 1.22-2.93). Combined use of psychotropic agents was associated with higher risk of stroke than monotherapy (AOR = 2.62; 95% CI = 1.98-3.45). DISCUSSIONS The results support our hypothesis that psychotropic use is associated with increased risk of stroke among patients with bipolar disorders. The stroke risks are higher among patients with polypharmacy than those with monotherapy. These findings warrant further investigation to confirm and replicate the findings using different methodologies and populations, and to mitigate residual confounding.

Abstract
Bipolar illnesses are typically considered as disorders primarily occurring in adult life, but a substantial number have their onset during the teenage years. Any acute illness in the teenage years affects social, emotional and educational development disproportionately, as it may prevent the normal transitions and learning experiences inherent in adolescence. Additionally, there is some evidence for a lack of early recognition or for misdiagnosis in early-onset cases of psychiatric disorders in general and the psychotic disorders in particular, with consequent increased suffering and impairment of functioning. Finally, bipolar affective disorders rarely present with one single episode followed by full and permanent recovery, but are usually illnesses characterised by a relapsing and remitting course through adult life. Prompt and effective recognition and treatment may therefore not merely reduce immediate impact but may also set up patterns of understanding and treatment compliance with longer-term implications. In this paper, I consider the particular features of bipolar affective disorder in adolescence and to describe a practical framework for its management. In view of the relative lack of age-specific research findings, particularly in respect of treatment effectiveness, I draw heavily upon clinical practice and extrapolation from studies carried out among adult sufferers.

Abstract
BACKGROUND Many people with schizophrenia do not achieve a satisfactory treatment response with ordinary antipsychotic drug treatment. In these cases, various add-on medications are used, and valproate is one of these. OBJECTIVES To examine whether:1. valproate alone is an effective treatment for schizophrenia and schizoaffective psychoses; and2. valproate augmentation of antipsychotic medication is an effective treatment for the same illnesses. SEARCH METHODS We searched the Cochrane Schizophrenia Group's Study-Based Register of Trials (July 2002; February 2007; July 2012; March 04, 2016). We also contacted pharmaceutical companies and authors of relevant studies in order to identify further trials. SELECTION CRITERIA We included all randomised controlled trials comparing valproate to antipsychotics or to placebo (or no intervention), whether as the sole agent or as an adjunct to antipsychotic medication for the treatment of people with schizophrenia or schizophrenia-like psychoses. DATA COLLECTION AND ANALYSIS We independently inspected citations and, where possible, abstracts, ordered papers, and re-inspected and quality-assessed these. At least two review authors independently extracted data. We analysed dichotomous data using risk ratio (RR) and its 95% confidence intervals (CI). We analysed continuous data using mean differences (MD) and their 95% CI. We assessed risk of bias for included studies and used GRADE (Grading of Recommendations Assessment, Development and Evaluation) to create a 'Summary of findings' table. MAIN RESULTS The 2012 update search identified 19 further relevant studies, most of which were from China. Thus the review currently includes 26 studies with a total of 2184 participants. All trials examined the effectiveness of valproate as an adjunct to antipsychotics. With the exception of two studies, the studies were small, the participants and personnel were not blinded (neither was outcome assessment), and most were short-term and incompletely reported.For this update we prespecified seven main outcomes of interest: clinical response (clinically significant response, aggression/agitation), leaving the study early (acceptability of treatment, overall tolerability), adverse events (sedation, weight gain) and quality of life.Adding valproate to antipsychotic treatment resulted in more clinically significant response than adding placebo to antipsychotic drugs (14 RCTs, n = 1049, RR 1.31, 95% CI 1.16 to 1.47, I2 = 12%, low-quality evidence). However, this effect was removed after excluding open RCTs in a sensitivity analysis. In terms of acceptability of treatment (measured by the number of participants leaving the study early due to any reason) valproate was just as acceptable as placebo (11 RCTs, n = 951, RR 0.76, 95% CI 0.47 to 1.24, I2 = 55%). Also overall tolerability (measured by the number of participants leaving the study early for adverse events) between valproate and placebo was similar (6 RCTs, n = 974, RR 1.33, 95% CI 0.90 to 1.97, I2 = 0).Participants in the valproate group were found to be less aggressive than the control group based on the Modified Overt Aggression Scale (3 RCTs, n = 186, MD -2.55, 95% CI -3.92 to -1.19, I2 = 82%, very low-quality evidence). Participants receiving valproate more frequently experienced sedation (8 RCTs, n = 770, RR 1.38, 95% CI 1.07 to 1.79, I2 = 0, low-quality evidence) but were no more likely to gain weight than those receiving placebo (4 RCTs, n = 427, RR 1.17, 95% CI 0.76 to 1.82, I2 = 0, low-quality evidence). No study reported on the important outcome of quality of life. AUTHORS' CONCLUSIONS There is limited evidence, based on a number of trials, that the augmentation of antipsychotics with valproate may be effective for overall clinical response, and also for specific symptoms, especially in terms of excitement and aggression. However, this evidence was entirely based on open RCTs. Moreover, valproate was associated with a number of adverse events among which sedation and dizziness appeared significantly more frequently than in the control groups. Further randomised studies which are blinded are necessary before any clear recommendation can be made. Ideally these would focus on people with schizophrenia and aggression, on those with treatment-resistant forms of the illness and on those with schizoaffective disorders.

Abstract
CONTEXT Treatment-resistant bipolar disorder (TRBD) is an increasingly prevalent, debilitating condition with substandard treatment outcomes. Polypharmacy has become the mainstay among practitioners though long-term efficacy of this method has not been adequately tested. OBJECTIVE Determine retrospectively if individualized, integrative treatment strategies applied while withdrawing pharmaceuticals were beneficial and safe among a TRBD clinic population. DESIGN A chart review was performed for six adult patients, treated in a private psychiatric practice. Data were collected regarding psychiatric diagnosis, hospitalizations, medications, side effects, substance abuse, and applied treatments. RESULTS Using individualized, integrative psychiatric treatment methods, the majority of medications were eliminated. Long-term remission was attained in all cases, defined as clinical stability with no discernable symptoms of bipolar disorder for at least one year. CONCLUSIONS Applying an integrative treatment approach, and eliminating most medications, provided lasting resolution of symptoms and side effects in a selected sample of TRBD outpatients. These data may provide the basis for future randomized, controlled trials.

Abstract
A vast majority of psychiatric patients are effectively treated with combination of drugs to improve efficacy and adherence, but due to limited research and development in fixed dose combination (FDC) in psychiatry, these products are not commonly available. The aim of this study is to prepare cost effective FDC tablets containing aripiprazole and divalproex sodium. Two batches of fixed dose combination tablets, FDC1 and FDC2, were successfully prepared using wet granulation technique. Furthermore, aripiprazole tablets A1 and A2 and divalproex tablets D1 were also formulated as reference to compare the in vitro availability profile. An accurate and simple isocratic HPLC method was established and validated for the simultaneous quantification of aripiprazole and valproic acid in the FDC tablets. A reversed-phase C18 (250 × 4.6 mm) column in isocratic mode was used. The mobile phase consisted of acetonitrile and 0.32% KH2PO4 (60:40, v/v), flow rate was set at 1.0 mL/min and the detection was performed at 210 nm. Average percent recoveries of aripiprazole and valproic acid were 96.0 and 95.5%, respectively, meeting the official requirements. The newly developed FDC product may be used for the better therapeutic outcomes of combined use of aripiprazole and valproic acid, which may improve patient adherence.

Anterior cingulate Glutamate-Glutamine cycle metabolites are altered in euthymic bipolar I disorder. Eur Neuropsychopharmacol 2015; 25:2221-9.

Abstract
Bipolar disorder (BD) has been consistently associated with abnormalities in the Glutamate/GABA-Glutamine cycle. Magnetic resonance spectroscopy (MRS) studies have reported increased brain Glutamate (Glu) and Glx (Glu+Glutamine) in subjects with BD. However, data on separate measures of GABA and Glutamine (Gln) in BD are sparse due to overlapping resonant signals. The development of new sequence methods in the quantification of these metabolites has allowed a better understanding of the Glu/GABA-Gln cycle but data on this field of research remains sparse in BD. Eighty-eight subjects (50 euthymic BD and 38 HC) underwent 3T proton magnetic resonance spectroscopy (1H MRS) in the anterior cingulate cortex (ACC; 2×2×4.5cm(3)) using a two-dimensional JPRESS sequence. GABA, Glutamine (Gln) and Glutamate (Glu) were quantified with the ProFit program. Using image segmentation and known creatine (Cre) concentrations for white and grey matter, metabolite concentrations were calculated for the excited MRS voxel. GABA levels did not differ between groups. Gln level was higher in euthymic BD patients than in healthy controls. The Glu level and Glu/Gln ratio were lower in BD patients than in controls. The use of anticonvulsants was associated with Gln increase but did not affect Glu or Glu/Gln. Neither lithium nor antipsychotic use influenced metabolite levels. The ACC MRS findings indicate that the glutamatergic function in euthymic medicated BD patients is altered relative to controls. Whether this feature is a metabolic signature of euthymic BD subjects should be the focus of future studies.

Abstract
Psychopharmacological treatment has been the mainstay in long-term maintenance of bipolar disorder (BD) patients for the last 60 years. Conventionally accepted treatment options are primarily based on expert opinion rather than on well-executed, independently funded research. Investigation of maintaining patients without medications using treatment alternatives has been neglected. This clinical case series examines the outcomes of 7 BD patients who experienced a poor response or significant side effects with conventional treatment modalities. Patients were gradually and safely withdrawn from all medications. Treatment strategies were based on an individualized holistic approach using herbs, nutritional supplements, vitamins, amino acids, acupuncture, dietary recommendations, and behavioral modifications. Multiple treatment modalities were combined addressing the etiological causes for BD symptoms. Upon withdrawal from psychotropic medications, patients were free of medication-induced side effects and obtained psychiatric stability for at least 10 months. Further research is needed to investigate the long-term outcomes of BD treatment modalities based on well-defined successful outcome criteria, such as reduction in symptoms, improvement in quality of life, overall health outcomes, and cost effectiveness.

Abstract
The majority of patients treated for bipolar disorder receive multiple psychotropic medications concurrently (polypharmacy), despite a lack of empirical evidence for any combination of three or more medications. Some patients benefit from the skillful management of a complex medication regimen, but iterative additions to a treatment regimen often do not lead to clinical improvement, are expensive, and can confound assessment of the underlying mood disorder. Given these potential problems of polypharmacy, this paper reviews the evidence supporting the use of multiple medications and seeks to identify patient personality traits that may put patients at a greater risk for ineffective complex chronic care. Patients with bipolar disorder (n = 89), ages 18 and older, were assessed on the Montgomery Asberg Depression Rating Scale (MADRS), Young Mania Rating Scale (YMRS), and the NEO Five Factor Inventory (NEO-FFI), and completed a treatment history questionnaire to report psychotropic medication use. We found that patients with lower scores on openness had significantly more current psychotropic medications than patients with higher scores on openness (3.7 ± 1.9 vs. 2.8 ± 1.8, p < 0.05). Patients with the highest lifetime medication use had significantly lower extraversion (21.8 ± 8.9 vs. 25.4 ± 7.6, p < 0.05) and lower conscientiousness (21.9 ± 8.2 vs. 27.9 ± 8.2, p < 0.01) than those reporting lower lifetime medication use. Low levels of openness, extraversion, and conscientiousness may be associated with increased psychotropic medication use. Investigating the role of individual differences, such as patient personality traits, in moderating effective polypharmacy warrants future research.

Therapeutic concentrations of valproate but not amitriptyline increase neuropeptide Y (NPY) expression in the human SH-SY5Y neuroblastoma cell line. ACTA ACUST UNITED AC 2013; 186:123-30. [PMID: 23994577 DOI: 10.1016/j.regpep.2013.08.005] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2012] [Revised: 08/05/2013] [Accepted: 08/12/2013] [Indexed: 01/26/2023]
Abstract
Neuropeptide Y (NPY) is a peptide found in the brain and autonomic nervous system, which is associated with anxiety, depression, epilepsy, learning and memory, sleep, obesity and circadian rhythms. NPY has recently gained much attention as an endogenous antiepileptic and antidepressant agent, as drugs with antiepileptic and/or mood-stabilizing properties may exert their action by increasing NPY concentrations, which in turn can reduce anxiety and depression levels, dampen seizures or increase seizure threshold. We have used human neuroblastoma SH-SY5Y cells to investigate the effect of valproate (VPA) and amitriptyline (AMI) on NPY expression at therapeutic plasma concentrations of 0.6mM and 630nM, respectively. In addition, 12-O-tetradecanoylphorbol-13-acetate (TPA) known to differentiate SH-SY5Y cells into a neuronal phenotype and to increase NPY expression through activation of protein kinase C (PKC) was applied as a positive control (16nM). Cell viability after drug treatment was tested with a 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. NPY expression was measured using immunofluorescence and quantitative RT-PCR (qRT-PCR). Results from immunocytochemistry have shown NPY levels to be significantly increased following a 72h but not 24h VPA treatment. A further increase in expression was observed with simultaneous VPA and TPA treatment, suggesting that the two agents may increase NPY expression through different mechanisms. The increase in NPY mRNA by VPA and TPA was confirmed with qRT-PCR after 72h. In contrast, AMI had no effect on NPY expression in SH-SY5Y cells. Together, the data point to an elevation of human NPY mRNA and peptide levels by therapeutic concentrations of VPA following chronic treatment. Thus, upregulation of NPY may have an impact in anti-cancer treatment of neuroblastomas with VPA, and antagonizing hypothalamic NPY effects may help to ameliorate VPA-induced weight gain and obesity without interfering with the desired central effects of VPA.

Abstract
Mood disorders that have no medical or pharmacological causes are divided into depressive disorders (unipolar, or major depressive disorder) and bipolar disorders. In bipolar disorders, both depressive and manic episodes occur sequentially.A manic episode is characterised as an abnormally excited mood that is experienced by a patient for a distinct period (at least a week). Diagnosis of mania requires that a patient’s work and social life be significantly affected, or that the patient needs hospitalisation. Diagnosis also requires the presence of three or more of the following symptoms: inflated self-esteem or grandiosity; decreased need for sleep; increased talkativeness; racing thoughts/ideas; distraction; increased goal-directed activity; excessive involvement in pleasurable activities [1].

Abstract
BACKGROUND The Bipolar Comprehensive Outcomes Study (BCOS) is a 2-year, prospective, non-interventional, observational study designed to explore the clinical and functional outcomes associated with 'real-world' treatment of participants with bipolar I or schizoaffective disorder. All participants received treatment as usual. There was no study medication. METHODS Participants prescribed either conventional mood stabilizers (CMS; n = 155) alone, or olanzapine with, or without, CMS (olanzapine ± CMS; n = 84) were assessed every 3 months using several measures, including the Young Mania Rating Scale, 21-item Hamilton Depression Rating Scale, Clinical Global Impressions Scale - Bipolar Version, and the EuroQol Instrument. This paper reports 24-month longitudinal clinical, pharmacological, functional, and socioeconomic data. RESULTS On average, participants were 42 (range 18 to 79) years of age, 58%; were female, and 73%; had a diagnosis of bipolar I. Polypharmacy was the usual approach to pharmacological treatment; participants took a median of 5 different psychotropic medications over the course of the study, and spent a median proportion of time of 100%; of the study on mood stabilizers, 90%; on antipsychotics, 9%; on antidepressants, and 5%; on benzodiazepines/hypnotics. By 24 months, the majority of participants had achieved both symptomatic and syndromal remission of both mania and depression. Symptomatic relapse rates were similar for both the CMS alone (65%;) and the olanzapine ± CMS (61%;) cohorts. CONCLUSIONS Participants with bipolar I or schizoaffective disorder in this study were receiving complex medication treatments that were often discordant with recommendations made in contemporary major treatment guidelines. The majority of study participants demonstrated some clinical and functional improvements, but not all achieved remission of symptoms or syndrome.

Abstract
PURPOSE Childhood cancer survivors are at risk for late effects which may be managed pharmacologically. The purposes of this study were to estimate and compare the prevalence of psychoactive medication use of adult survivors of childhood cancer and sibling controls, identify predictors of medication use in survivors, and investigate associations between psychoactive medications and health-related quality of life (HRQOL). METHODS Psychoactive medication use from 1994 to 2010 was evaluated in 10,378 adult survivors from the Childhood Cancer Survivor Study. A randomly selected subset of 3,206 siblings served as a comparison group. Multivariable logistic regression models were used to calculate odds ratios (OR) for baseline and new onset of self-reported psychoactive medication use and HRQOL. RESULTS Survivors were significantly more likely to report baseline (22 vs. 15 %, p < 0.001) and new onset (31 vs. 25 %, p < 0.001) psychoactive medication use compared to siblings, as well as use of multiple medications (p < 0.001). In multivariable models, controlling for pain and psychological distress, female survivors were significantly more likely to report baseline and new onset use of antidepressants (OR = 2.66, 95 % CI = 2.01-3.52; OR = 2.02, 95 % CI = 1.72-2.38, respectively) and multiple medications (OR = 1.80, 95 % CI = 1.48-2.19; OR = 1.77, 95 % CI = 1.48-2.13, respectively). Non-cranial radiation and amputation predicted incident use of analgesics >15 years following diagnosis. Antidepressants were associated with impairment across all domains of HRQOL, with the exception of physical function. CONCLUSIONS Prevalence of psychoactive medication use was higher among survivors for most medication classes, as was the use of multiple medications. Clinicians should be aware of the possible contribution of psychoactive medications to HRQOL. IMPLICATIONS FOR CANCER SURVIVORS Survivors of childhood cancer are more likely to be prescribed psychoactive medication than their sibling counterparts, though use of such medication does not appear to normalize quality of life. Survivors are encouraged to consider additional interventions, including psychosocial support and physical exercise.

Abstract
Although much progress has been made in successfully treating bipolar disorder, there is increasing awareness of the limitations of traditional treatment regimens such as lithium and neuroleptics. The large family of anticonvulsant drugs, however, appears to be capable of providing new treatment options, not only as medication of second choice in patients refractory to treatment, but often as a treatment standard with high efficacy and low incidence of side effects. Besides established mood stabilizers such as carbamazepine and valproate, new antiepileptic drugs are entering the field with promising initial results in the treatment of bipolar patients. Furthermore, bringing to light the mechanisms of action of anticonvulsants and the similarities between anticonvulsants effective in bipolar disorder may also deepen our understanding of the pathophysiological basis of the disorder.

Abstract
OBJECTIVES This article addresses the clinical role for ziprasidone used adjunctively with a mood stabilizer in maintenance treatment of bipolar disorder. This review also addresses the strengths and limitations of design features in adjunctive studies of second-generation antipsychotic drugs added to mood stabilizers. METHODS The principal study relevant to this review enrolled subjects who were ≥18 years of age, experiencing a recent or current manic or mixed bipolar I episode, with at least moderately severe current manic symptoms. To meet criteria for randomization to 6 months maintenance treatment, patients had to have failed a short course of treatment with either lithium or valproate and achieved benefit with added ziprasidone for 8 consecutive weeks. RESULTS Time to intervention for a new mood episode as well as time to discontinuation for any reason was significantly longer with adjunctive ziprasidone treatment than with monotherapy treatment with mood stabilizer. Three dosages of ziprasidone augmentation were studied. Patients treated with 120 mg/day had better efficacy and overall outcomes than did patients who received 80 or 160 mg/day of ziprasidone. CONCLUSIONS Good evidence exists that adjunctive ziprasidone will likely provide greater overall efficacy coupled with good tolerability for at least a 6-month period than a strategy of continued monotherapy with a mood stabilizer. Changes in open phases of maintenance studies to reduce study enrichment, in study endpoints, and in statistical approaches to analysis of data are warranted.

Abstract
BACKGROUND Lithium carbonate and valproate semisodium are both recommended as monotherapy for prevention of relapse in bipolar disorder, but are not individually fully effective in many patients. If combination therapy with both agents is better than monotherapy, many relapses and consequent disability could be avoided. We aimed to establish whether lithium plus valproate was better than monotherapy with either drug alone for relapse prevention in bipolar I disorder. METHODS 330 patients aged 16 years and older with bipolar I disorder from 41 sites in the UK, France, USA, and Italy were randomly allocated to open-label lithium monotherapy (plasma concentration 0.4-1.0 mmol/L, n=110), valproate monotherapy (750-1250 mg, n=110), or both agents in combination (n=110), after an active run-in of 4-8 weeks on the combination. Randomisation was by computer program, and investigators and participants were informed of treatment allocation. All outcome events were considered by the trial management team, who were masked to treatment assignment. Participants were followed up for up to 24 months. The primary outcome was initiation of new intervention for an emergent mood episode, which was compared between groups by Cox regression. Analysis was by intention to treat. This study is registered, number ISRCTN 55261332. FINDINGS 59 (54%) of 110 people in the combination therapy group, 65 (59%) of 110 in the lithium group, and 76 (69%) of 110 in the valproate group had a primary outcome event during follow-up. Hazard ratios for the primary outcome were 0.59 (95% CI 0.42-0.83, p=0.0023) for combination therapy versus valproate, 0.82 (0.58-1.17, p=0.27) for combination therapy versus lithium, and 0.71 (0.51-1.00, p=0.0472) for lithium versus valproate. 16 participants had serious adverse events after randomisation: seven receiving valproate monotherapy (three deaths); five lithium monotherapy (two deaths); and four combination therapy (one death). INTERPRETATION For people with bipolar I disorder, for whom long-term therapy is clinically indicated, both combination therapy with lithium plus valproate and lithium monotherapy are more likely to prevent relapse than is valproate monotherapy. This benefit seems to be irrespective of baseline severity of illness and is maintained for up to 2 years. BALANCE could neither reliably confirm nor refute a benefit of combination therapy compared with lithium monotherapy. FUNDING Stanley Medical Research Institute; Sanofi-Aventis.

Abstract
BACKGROUND Recent data indicate that lithium use for bipolar disorder has declined over the last decade and that lithium largely has been replaced with alternate, commercially promoted medications that may or may not result in better outcomes. PURPOSE This article describes the rationale and study design of LiTMUS, a multi-site, prospective, randomized clinical trial of outpatients with bipolar disorder. LiTMUS seeks to address whether initiating therapy at lower doses of lithium as part of optimized treatment (OPT, guideline-informed, evidence-based, and personalized pharmacotherapy) improves outcomes and decreases the need for other medication changes across 6 months of therapy. METHODS LiTMUS will randomize 284 adults with bipolar disorder (Type I or II) across 6 study sites. The co-primary outcomes are overall illness severity on clinical global improvement scale for bipolar disorder and a novel measure, necessary clinical adjustments. This metric provides a composite that reflects both clinical response and tolerability. Other relevant outcomes include full symptomatic recovery, quality of life, suicidal behaviors, and moderators of suicidality. RESULTS As of August 28th, 2009, we have consented 338 patients and randomized 281 for this study. LIMITATIONS The potential limitations of the study include an arbitrary definition of 'low, but effective' doses of lithium, lack of a placebo-controlled group, open treatment, and use of a new outcome measure (i.e., necessary clinical adjustments). CONCLUSION We expect that this study will inform our understanding of the effectiveness of low to moderate doses of lithium therapy for individuals with bipolar disorder.

Abstract
INTRODUCTION Semantic memory impairments in schizophrenia have been reported across a wide range of neuropsychological tests. Set against a backdrop of fairly widespread cognitive impairments, it is difficult to know whether there is a primary, or secondary, impairment of semantic memory in schizophrenia. Also, whether there is a profile of differential impairment across the range of neuropsychological tests. METHODS Employing a systematic search strategy, 91 papers were identified which have assessed participants with schizophrenia on a measure of semantic memory. A series of meta-analyses were then conducted which provided combined weighted means for performance on tasks of naming, word-picture matching, verbal fluency, priming, and categorisation. RESULTS An uneven profile of impairment is reported with large effect sizes for tests of naming and verbal fluency, medium effect sizes for word-picture matching and association and small effect sizes for categorisation and priming tests. CONCLUSIONS This uneven profile supports the claim that a degradation of semantic knowledge may not be adequate in explaining the semantic memory impairment in schizophrenia. This conclusion is supported by the data which report a relationship between an executive dysfunction and poor priming and fluency performance particularly. The data support a link between Formal Thought Disorder and semantic memory impairments on tests of naming and verbal fluency but on other tests evidence is equivocal.

Abstract
BACKGROUND Lithium is an important drug in the treatment of bipolar disorder. Earlier epidemiological studies of lithium use have depended on sales statistics, clinical surveys or population surveys. The national prescription databases in Denmark, Norway and Sweden may help provide more reliable information on the epidemiology of lithium use. METHODS Data were taken from the three national prescription databases in Denmark, Norway and Sweden from July 2005 until June 2006, encompassing 1 year of prescription data. Similar methods were used to identify a number of different pharmacoepidemiological measures and data were collected for adults aged 18-69 at the time of prescription. RESULTS Norway and Sweden had higher sales and more prevalent use than Denmark. In all three countries, more female than males were treated and the prevalence of use increased linearly with age. In all, 0.17, 0.21, and 0.25% of the populations in Denmark, Norway and Sweden respectively redeemed at least 1 prescription for lithium in the period studied. The amount prescribed per user per year varied with age, increasing to maximum doses at 40 years of age and then decreasing. CONCLUSION This study is the first attempt to use prescription databases in all three Scandinavian countries to describe in detail the epidemiology of a drug's use. The analysis revealed subtle differences in the clinical use of lithium that cannot be explained by differences in the epidemiology of bipolar disorder.

Abstract
BACKGROUND Despite the lack of randomized controlled trials (RCTs), gabapentin use increased rapidly in the 1990s for mental health conditions. Subsequent RCTs did not demonstrate efficacy for bipolar disorder (BD). We examined the characteristics of review articles to determine their potential role in the growth of gabapentin for BD. METHODS We searched MEDLINE, the International Pharmaceutical Abstracts and LexisNexis for review articles or commentaries examining the role of gabapentin for BD. Electronic searches were supplemented by manual searches of reference lists. Articles were abstracted for the types of evidence cited, source of evidence, the proportion of available RCTs cited and narrative blurbs discussing the role of gabapentin for BD. Review articles were classified as narrative versus systematic and positive, neutral or negative regarding the role of gabapentin in BD. RESULTS We included 27 review articles published between 1998 and 2008, but no commentaries met eligibility criteria. Most did not describe potential conflicts of interest or a funding source, and the 3 systematic reviews were of low quality. The 11 reviews published prior to the first RCT of gabapentin for BD cited uncontrolled trials or case series (n=9), basic science (n=6), chart reviews (n=3) or unpublished RCTs (n=2). Six recommended gabapentin, 3 were neutral and 2 were negative. The 16 articles published after the first gabapentin RCT continued to cite uncontrolled trials and basic science; only 5 cited all the available RCTs. However, more of these reviews (n=10) reached negative conclusions about the role of gabapentin for BD. CONCLUSIONS Narrative and low-quality systematic reviews, principally those published prior to RCTs, may have contributed to the growth of gabapentin use for BD. High-quality systematic reviews are needed to inform clinicians and policymakers about the effectiveness of new treatments.

Abstract
The treatment of mania starts with a correct diagnosis and elementary measures to prevent risks for the patient, relatives, and others. Sometimes, compulsory admission and treatment may be required for a few days. Patients with psychotic or mixed mania may be more difficult to treat. At the present time, there is solid evidence supporting the use of lithium, the anticonvulsants valproate and carbamazepine, and the antipsychotics chlorpromazine, haloperidol, risperidone, olanzapine, quetiapine, ziprasidone, aripiprazole, and asenapine in acute mania, and some evidence supporting the use of clozapine or electroconvulsive therapy in treatment-refractory cases. However, in clinical practice, combination therapy is the rule rather than the exception. The treatment of acute mania deserves a long-term view, and the evidence base for some treatments may be stronger than for others. When taking decisions about treatment, tolerability should also be a major concern, as differences in safety and tolerability may exceed differences in efficacy for most compounds. Psychoeducation of patients and caregivers is a powerful tool that should be used in combination with medication for optimal long-term outcome. Functional recovery should be the ultimate goal.

Abstract
Lithium and valproic acid (VPA) are two primary drugs used to treat bipolar mood disorder and have frequently been used in combination to treat bipolar patients resistant to monotherapy with either drug. Lithium, a glycogen synthase kinase-3 (GSK-3) inhibitor, and VPA, a histone deacetylase (HDAC) inhibitor, have neuroprotective effects. The present study was undertaken to demonstrate synergistic neuroprotective effects when both drugs were coadministered. Pretreatment of aging cerebellar granule cells with lithium or VPA alone provided little or no neuroprotection against glutamate-induced cell death. However, copresence of both drugs resulted in complete blockade of glutamate excitotoxicity. Combined treatment with lithium and VPA potentiated serine phosphorylation of GSK-3 alpha and beta isoforms and inhibition of GSK-3 enzyme activity. Transfection with GSK-3alpha small interfering RNA (siRNA) and/or GSK-3beta siRNA mimicked the ability of lithium to induce synergistic protection with VPA. HDAC1 siRNA or other HDAC inhibitors (phenylbutyrate, sodium butyrate or trichostatin A) also caused synergistic neuroprotection together with lithium. Moreover, combination of lithium and HDAC inhibitors potentiated beta-catenin-dependent, Lef/Tcf-mediated transcriptional activity. An additive increase in GSK-3 serine phosphorylation was also observed in mice chronically treated with lithium and VPA. Together, for the first time, our results demonstrate synergistic neuroprotective effects of lithium and HDAC inhibitors and suggest that GSK-3 inhibition is a likely molecular target for the synergistic neuroprotection. Our results may have implications for the combined use of lithium and VPA in treating bipolar disorder. Additionally, combined use of both drugs may be warranted for clinical trials to treat glutamate-related neurodegenerative diseases.

Abstract
OBJECTIVE A post-hoc, descriptive analysis was undertaken to assess the tolerability of and changes in psychiatric rating scales with lamotrigine (LTG) administered concomitantly with commonly prescribed bipolar medications. METHODS During the 8- to 16-week, open-label, preliminary phase of two large clinical trials of patients (N=1,305) with bipolar I disorder, LTG was added to each patient's existing psychotropic regimen. Medications for acute symptoms could have been added and later discontinued to achieve LTG monotherapy. Data were compared for patients taking LTG with or without concomitant valproate, lithium, any atypical antipsychotic, or any selective serotonin reuptake inhibitor. RESULTS The percentages of patients with any reported adverse event and reported adverse events of mood symptoms or rash were comparable between those taking LTG with or without other concomitant bipolar medications. Adverse events in >10% of patients in at least one subgroup were headache, infection, nausea, rash, influenza, diarrhea, dizziness, and somnolence. Baseline scores on psychiatric rating scales improved similarly with LTG co-administered with other bipolar medications, and the pattern of results did not differ by baseline polarity of mood symptoms. CONCLUSION LTG co-administered with valproate, lithium, an atypical antipsychotic, or a selective serotonin reuptake inhibitor in the treatment of bipolar disorder seemed to be well tolerated and was associated with clinical improvement.

Abstract
There is currently no consensus on how to manage the psychiatric manifestations of neurosyphilis, despite the resurgence of this condition. The authors present five cases of neurosyphilis in inpatient psychiatric settings that manifested with predominantly psychiatric symptoms and were appropriately diagnosed and successfully treated with psychotropic medication concurrent with antibiotic therapy. A review of available data reveals that presently there are no specific guidelines to address psychiatric symptomatology in neurosyphilis. The authors see merit in the prudent use of psychotropic medication to achieve symptom stabilization.

Abstract
OBJECTIVE To provide an overview of the available high quality evidence-base of studies of adjunctive pharmacologic treatment for acute mania. METHOD Double-blind controlled trials with adequate samples (n > 100) were identified through search of PubMed/MEDLINE and computerized abstracts from 2004-2006 meetings of the American Psychiatric Association, International Conference on Bipolar Disorder, and Collegium Internationale Neuro-Psychopharmacolium using key words mania, adjunct, and combination. RESULTS Placebo-controlled studies with positive results support the adjunctive use of five agents including valproate, olanzapine, risperidone, quetiapine, and haloperidol. Agents with only negative or failed placebo-controlled studies included carbamazepine, gabapentin, lamotrigine, topiramate, oxcarbazepine, and ziprasidone. We found no placebo-controlled study of many commonly used agents including lithium, aripiprazole, and clozapine. No studies explicitly excluded subjects, based on prior treatment with the monotherapy being offered and several studies limited randomization to patients with documented inadequate response to the monotherapy arm. CONCLUSION The available placebo-controlled randomized clinical trials support adjunctive therapy combining lithium or valproate with olanzapine, risperidone, haloperidol or quetiapine. The additional increment of antimanic efficacy of these combinations over monotherapy was similar in magnitude to that seen for the same agents as monotherapy in comparison with placebo. These additive benefits enhanced the tolerability of adverse effects sufficiently to allow a higher proportion of subjects receiving combination therapies to complete the studies than monotherapy treated patients. The available data has several shortcomings and the available studies are inadequate to conclusively determine whether combination treatment is more efficacious than monotherapy when used by subjects naive to both treatments. Nevertheless, adjunctive treatment, which combines agents with proven antimanic efficacy, offers an attractive option for patients with acute mania.

Abstract
BACKGROUND Breakthrough manic episodes are the rule in bipolar disorders; valproate and olanzapine are considered first-line treatments for manic episodes, nevertheless the two drugs have only been compared in monotherapy studies. In our study we compared the efficacy and safety of valproate and olanzapine added to lithium in the treatment of patients experiencing breakthrough manic episodes while on lithium monotherapy. METHODS Patients with bipolar I or II disorder (SCID-I), in treatment with lithium since at least one year, experiencing a manic or hypomanic relapse were randomly assigned to an open-label add-on therapy with valproate (500-1500 mg/day) or olanzapine (7.5-15.0 mg/day) for 8 weeks. The primary efficacy measure was the Young Mania Rating Scale (YMRS) total. RESULTS Twenty-one patients were randomized to receive the add-on therapy with valproate (n=9) or olanzapine (n=12). Both groups showed a significant baseline to endpoint reduction in YMRS total and Clinical Global Impressions-Severity (CGI-S) scores (p<0.001). At endpoint, the mean reduction of YMRS total or CGI-S scores, as well as response or remission rates, was not significantly different between the groups. However, compared with patients in the valproate add-on group, patients treated with olanzapine add-on showed significantly greater reductions in the YMRS total and CGI-S mean scores at weeks 1 through 4 (p<0.05). The rate and profile of adverse events were numerically similar in the two groups. LIMITATIONS Open-label design and limited sample size. CONCLUSION Both add-on therapies were efficacious in treating patients with manic or hypomanic relapse, however the olanzapine group showed an earlier response to treatment. These findings can help clinicians in understanding the value of adding other treatments to lithium in patients experiencing a manic or hypomanic relapse.

Abstract
INTRODUCTION The aim of this meta-analysis was to systematically review the effectiveness of co-therapy compared with monotherapy for people with bipolar mania. METHOD MEDLINE, Embase, Psychinfo, The Cochrane Library and reference lists of retrieved studies were searched without language restrictions for randomized controlled trials evaluating co-therapy compared with monotherapy for acute bipolar mania. Each trial was assessed for susceptibility to bias. Data on mania outcomes, withdrawals, extrapyramidal symptoms and weight were extracted and pooled effect estimates summarized as relative risks (RR) or differences in mean values (MD) where appropriate. RESULTS Eight eligible studies were included (1124 participants). Significant reductions in mania (Young Mania Rating Scale, YMRS) scores were shown for haloperidol, olanzapine, risperidone and quetiapine as co-therapy compared with monotherapy with a mood stabilizer. For atypical antipsychotics combined, the pooled difference in mean scores was 4.41 (95% CI: 2.74, 6.07). Significantly more participants on co-therapy met the response criterion (at least 50% reduction in YMRS score), RR 1.53 (1.31, 1.80). With some drugs, co-therapy decreased tolerability compared with monotherapy, and resulted in greater weight gain. There were insufficient data to compare one co-therapy regimen with another. CONCLUSION The addition of antipsychotic treatment to established mood-stabilizer treatment is more effective than mood-stabilizer treatment alone.

Abstract
Topiramate (TPM) is one of the novel antiepileptic drugs and exhibits a wide range of mechanisms of action. Efficacy of TPM has been demonstrated in partial-onset seizures and primary generalized seizures in adults and children, as both monotherapy and adjunctive therapy. More recently, TPM has been proposed as an add-on treatment for patients with lithium-resistant bipolar disorder, especially those displaying rapid-cycling and mixed states. This paper reviews the multiple mechanisms of action and the tolerability profile of TPM in the light of its therapeutic potential in affective disorders. Studies of TPM in bipolar disorder are evaluated, and the efficacy and tolerability issues as a mood stabilizing agent are discussed.

Abstract
AIM To assess the pharmacokinetic effect and tolerability of lamotrigine 200 mg day(-1) and olanzapine 15 mg day(-1) coadministration in healthy male volunteers. METHODS Subjects were randomized to receive either lamotrigine titrated on days 1-42 with olanzapine added on days 43-56 (LTG + OLZ group; N = 16), lamotrigine titration with placebo added on days 43-56 (LTG group; N = 12), or placebo on days 1-42 with olanzapine added on days 43-56 (OLZ group; N = 16). Steady state (0-24 h) pharmacokinetic profiles were determined on day 56 in each group. RESULTS The average (90% confidence interval) ratios of lamotrigine area under the concentration-time curve from 0 to 24 h and maximum observed concentration for the comparison of LTG + OLZ:LTG were 0.76 (0.65, 0.90) and 0.80 (0.71, 0.90), respectively. Olanzapine pharmacokinetics were essentially unaffected by lamotrigine. The most frequently reported adverse events (AEs) during combination therapy were fatigue, dizziness and mild transaminase elevations. These AEs occurred at similar frequencies in the LTG + OLZ and OLZ cohorts, while being less frequent or absent in the LTG group. CONCLUSIONS Lamotrigine and olanzapine coadministration in patients who may benefit from the combination was supported by this study. Lamotrigine dosing schedules are recommended to remain unchanged when combined with olanzapine therapy. However, the possibility exists that the lamotrigine dose for some patients may need adjustment to optimize treatment when olanzapine is added to or withdrawn from a regimen including lamotrigine.

Abstract
Bipolar Disorders affect up to 5% of the population. While the pharmacological options for the treatment of bipolar disorder have expanded over the past several years, lithium remains an inexpensive and efficacious treatment for bipolar disorder. Lithium has been demonstrated to be an effective treatment for acute mania, bipolar depression, the prophylactic treatment of bipolar disorder, and as an augmentation agent in the treatment of unipolar major depression. Lithium also is the only mood stabilizer that has been demonstrated to lower the suicide rate in patients with bipolar disorder. Use in special populations, side effects and toxicity, and drug interactions are discussed. Important laboratory monitoring guidelines are included in this review. Lithium remains an important intervention for the treatment of mood disorders.

Abstract
Through a review of randomised, controlled trials, this article evaluates the efficacy and tolerability of quetiapine in the acute and maintenance phases of bipolar disorder. In trials involving mania patients, quetiapine was found to be effective as adjunctive therapy in combination with lithium or valproate, significantly superior to placebo, and equal to lithium or haloperidol as monotherapy. With regard to the prevention of relapses in bipolar disorder, quetiapine seems to differ from other atypical antipsychotics in its characteristics as a mood stabiliser, which are associated with a promising efficacy in the treatment of bipolar depressive episodes. However, further larger controlled long-term prospective studies are needed to confirm the efficacy of quetiapine for the prevention of relapses in bipolar disorder. Quetiapine seems to have a satisfactory safety and tolerability profile, with a low prevalence of extrapyramidal symptom-related adverse events, treatment-emergent depression and weight gain. Sedation is the main side effect of treatment with quetiapine.
