Abstract
Antipsychotic drugs or neuroleptics are widely used in the treatment of psychosis as a manifestation of schizophrenia and bipolar disorder. However, their effectiveness largely depends on the blood-brain barrier (BBB) permeation (pharmacokinetics) and drug-receptor pharmacodynamics. Therefore, in this study, we developed and implemented the in silico pipeline to design novel compounds (n = 260) as leads using the standard drug scaffolds with improved PK/PD properties from the standard scaffolds. As a result, the best candidates (n = 3) were evaluated in molecular docking to interact with serotonin and dopamine receptors. Finally, haloperidol (HAL) derivative (1-(4-fluorophenyl)-4-(4-hydroxy-4-{4-[(2-phenyl-1,3-thiazol-4-yl)methyl]phenyl}piperidin-1-yl)butan-1-one) was identified as a "magic shotgun" lead compound with better affinity to the 5-HT2A, 5-HT1D, D2, D3, and 5-HT1B receptors than the control molecule. Additionally, this hit substance was predicted to possess similar BBB permeation properties and much lower toxicological profiles in comparison to HAL. Overall, the proposed rational drug design platform for novel antipsychotic drugs based on the BBB permeation and receptor binding might be an invaluable asset for a medicinal chemist or translational pharmacologist.Communicated by Ramaswamy H.

Abstract
Up to 80% of first-episode psychosis patients suffer a relapse within five years of the remission. Relapse should be an important focus of prevention given the potential harm to the patient and family. It threatens to disrupt their psychosocial recovery, increases the risk of resistance to treatment and has been associated with greater direct and indirect costs for society. Based on a previous project entitled "Genotype-phenotype and environment. Application to a predictive model in first psychotic episodes" (PEPs Project), the project "Clinical and neurobiological determinants of second episodes of schizophrenia. Longitudinal study of first episode of psychosis" was designed, also known as the 2EPs Project. It aimed to identify and characterize those factors that predict a relapse within the years immediately following a first episode. This project has focused on following the clinical course, with neuropsychological assessments, biological and neuroanatomical measures, genetic adherence and physical health monitoring in order to compare a subgroup of patients with a second episode to another group of patients which remains in remission. The main objective of the present article is to describe the rationale of the 2EPs Project, explaining the measurement approach adopted and providing an overview of the selected clinical and functional measures. 2EPs Project is a multicenter, coordinated, naturalistic, longitudinal follow-up study over three years in a Spanish sample of patients in remission after a first-psychotic episode of schizophrenia. It is closely monitoring the clinical course of the cases recruited to compare the subgroup of patients with a second episode to that which remains in remission. The sample is composed of 223 subjects recruited from 15 clinical centres in Spain with experience of the preceding PEPs Study project, albeit 2EPs being an expanded version with new basic groups in biological research. From the total sample recruited, 63 patients presented a relapse (44%). 2EPs arose to characterize first episodes in an exhaustive, novel and multimodal way, thus contributing towards the development of a predictive model of relapse. Identifying the characteristics of patients who relapse could improve early detection and intervention.

Abstract
OBJECTIVES To assess prevalence and pattern of movement disorders among patients taking antipsychotic medications. METHODS This cross-sectional, intensive monitoring (patient interview, case record form review and clinical examination) study was conducted in patients taking antipsychotic drugs irrespective of duration for the development of movement disorders. The psychiatrist used Modified Simpson-Angus Scale score (10-item scale), Barnes' rating scale and Abnormal Involuntary Movement Scale to diagnose parkinsonism, akathisia and tardive dyskinesia, respectively. We assessed movement disorders for the preventability and seriousness. RESULTS The overall prevalence of antipsychotic induced movement disorders was 5.67% (95% CI: 4.19-7.62). The prevalence of parkinsonism, akathisia and tardive dyskinesia was 5.10% (95% CI: 3.71-6.98), 0.85% (95% CI: 0.39-1.84) and 0.57% (95% CI: 0.22-1.45), respectively. There was a trend of high proportions of movement disorders in extreme of age group, female gender, patients treated with conventional antipsychotics, on poly therapy, patients of epilepsy with psychosis, schizophrenia and bipolar mood disorder. The movement disorder was lowest with quetiapine (2.02%). CONCLUSIONS The higher use of atypical antipsychotics had reduced the occurrence of movement disorders in our setup.

Abstract
Mood disorders continue to be a significant burden to those affected, resulting in significant illness-associated disability and premature mortality. In addition to mood disturbance, individuals also suffer from other transdiagnostic impairments (eg, anhedonia and cognitive impairment). Although there have been significant advancements in psychiatric treatment over the last few decades, treatment efficacy (eg, symptom remission, lack of functional recovery, and disease modification) continues to be an important limitation. Consequently, there is an urgent need to identify novel approaches capable of addressing the foregoing needs, providing the basis for the exploration of conceptual models and treatment opportunities that consider inflammation to be a key factor in mood disorder development. In part driven by metabolic comorbidities, a large proportion of individuals with mood disorders also have an imbalance in the inflammatory milieu. The aim of this review is to highlight evidence implicating inflammation in various effector systems in mood disorders, with a particular focus on the intercommunication with glutamatergic signaling, immune system signaling, as well as metabolic parameters (eg, L-methyl folate bioavailability). This article also briefly reviews novel and repurposed agents that are capable of targeting the innate immune inflammatory system and possibly correcting an abnormal immune/inflammatory milieu (eg, infliximab).

Abstract
BACKGROUND Atypical antipsychotic drug use by schizophrenia patients in Estonia increased from 32% in 2004 to 61% in 2009. AIMS To assess the prevalence of neuroleptic-induced movement disorders in the Estonian institutionalized population of schizophrenia patients twice over a period of eight years, before and after introduction of atypical antipsychotic drugs using DSM-IV criteria. METHODS DSM-IV criteria and specific rating scales were used to evaluate the prevalence of neuroleptic-induced movement disorders among 72 patients who participated in the study in 2009 compared to 99 patients who participated in 2001. RESULTS Despite increased use of atypical antipsychotics in the study population (up to 30% from 20%), the proportion of movement disorder-free population remained the same over 8 years - 38.9% in 2001 versus 38.4% in 2009. There were significant intra-individual fluctuations. Use of a typical antipsychotic resulted in an almost seven times higher risk of tardive dyskinesia after 8 years. Doses of antipsychotic drugs had no effect on the severity of neuroleptic-induced movement disorders. CONCLUSIONS Unfortunately, in 18% of patients the switch of medication from typical to atypical did not change the overall prevalence of neuroleptic-induced movement disorders in the group. The long-term benefit of atypical antipsychotics requires further research in patients who are treated with antipsychotics for years.

Abstract
BACKGROUND The challenges of comparative effectiveness to support health technology assessment (HTA) agencies are important considerations in the choices of antipsychotic medications for the treatment of schizophrenia. OBJECTIVES Our aim was to assess the study methods used and outcomes reported in the published literature to address the question of comparative effectiveness of newer antipsychotic agents and the adequacy and availability of evidence to support HTA agencies. DATA SOURCE A systematic search of the PubMed database from 1 January 2009 to 30 September 2013 was conducted to identify studies evaluating new atypical antipsychotics reporting on comparative effectiveness. STUDY SELECTION The systematic review comprised of studies on schizophrenia patients where at least two drugs were being compared and at least one treatment group received one of the following second-generation antipsychotics: risperidone, olanzapine, aripiprazole, paliperidone, asenapine, iloperidone, lurasidone, and quetiapine. The included studies were also required to have an efficacy, safety or economic outcome, such as Positive and Negative Syndrome Scale (PANSS) score, weight gain, resource utilization, or costs. STUDY APPRAISAL AND SYNTHESIS METHODS Two reviewers (BW and GK) independently applied the inclusion criteria. Disagreements between reviewers were resolved by consensus, referring to the original sources. Information on the methodology and outcomes was collected for each included study. This included study description, head-to-head drug comparison, patient population, study methodology, statistical methods, reported outcomes, study support, and journal type. RESULTS A total of 198 studies were identified from electronic search methods. The largest category of studies was randomized controlled trials [RCTs] (N = 73; 36.9%), which were largely directed at the regulatory endpoint. Fewer studies were undertaken for HTA-purposes cohort studies (N = 53; 26.8%), meta-analyses (N = 32; 16.2%), economic studies (N = 14; 7.1%), and cross-sectional studies (N = 13; 6.6%). Direct head-to-head comparisons preferred by HTA were dominated by the comparison involving olanzapine and risperidone, representing 149 (75.3%) and 119 (60.1%) studies, respectively. RCTs, which are the primary study type for regulatory submissions, showed a lack of bias. Studies aimed at HTA were not as well performed. Cohort studies suffered from bias in the selection of comparison groups, lack of control for confounders, and differential dropout rates. As a group, cross-sectional studies scored poorly for bias, with a primary failure to identify a representative sample. Economic studies showed highly variable bias, with bias in the representation of effectiveness data, model assumptions without validation, and lack of sensitivity analyses. LIMITATIONS One limitation of this systematic review is that it only included studies from 2009 to 2013, potentially excluding some earlier comparator studies, particularly those involving first-generation antipsychotics. CONCLUSIONS This review of comparative effectiveness studies of second-generation antipsychotic agents for schizophrenic patients revealed a wide range of study types, study methodologies, and outcomes. For traditional efficacy outcomes and select safety outcomes, there is strong evidence from many well-conducted studies; however, there are fewer studies of types preferred by HTA with limited head-to-head comparisons and a higher risk of bias in the execution of these studies.

Abstract
BACKGROUND Anxiety and related disorders include generalised anxiety disorder, obsessive-compulsive disorder, panic disorder, post-traumatic stress disorder and phobic disorders (intense fear of an object or situation). These disorders share the psychological and physical symptoms of anxiety, but each disorder has its own set of characteristic symptoms. Anxiety disorders can be difficult to recognise, particularly in older people (those aged over 65 years). Older people tend to be more reluctant to discuss mental health issues and there is the perception that older people are generally more worried than younger adults. It is estimated that between 3 and 14 out of every 100 older people have an anxiety disorder. Despite treatment, some people will continue to have symptoms of anxiety. People are generally considered to be 'resistant' or 'refractory' to treatment if they have an inadequate response or do not respond to their first treatment. Older adults with an anxiety disorder find it difficult to manage their day-to-day lives and are at an increased risk of comorbid depression, falls, physical and functional disability, and loneliness. OBJECTIVE To evaluate the effectiveness of pharmacological, psychological and alternative therapies in older adults with an anxiety disorder who have not responded, or have responded inadequately, to treatment. DATA SOURCES Electronic databases (MEDLINE, MEDLINE In-Process and Other Non-Indexed citations, EMBASE, The Cochrane Library databases, PsycINFO and Web of Science) were searched from inception to September 2013. Bibliographies of relevant systematic reviews were hand-searched to identify additional potentially relevant studies. ClinicalTrials.gov was searched for ongoing and planned studies. REVIEW METHODS A systematic review of the clinical effectiveness of treatments for treatment-resistant anxiety in older adults was carried out. RESULTS No randomised controlled trial or prospective comparative observational study was identified meeting the prespecified inclusion criteria. Therefore, it was not possible to draw any conclusions on clinical effectiveness. LIMITATIONS As no study was identified in older adults, there is uncertainty as to which treatments are clinically effective for older adults with an anxiety disorder who have not responded to prior treatment. The comprehensive methods implemented to carry out this review are a key strength of the research presented. However, this review highlights the extreme lack of research in this area, identifying no comparative studies, which is a marked limitation. CONCLUSIONS Specific studies evaluating interventions in older adults with an anxiety disorder who have not responded to first-line treatment are needed to address the lack of evidence. The lack of evidence in this area means that older adults are perhaps receiving inappropriate treatment or are not receiving a particular treatment because there is limited evidence to support its use. At this time there is scope to develop guidance on service provision and, as a consequence, to advance the standard of care received by older adults with a treatment-resistant anxiety disorder in primary and secondary care. Evaluation of the relative clinical effectiveness and acceptability of pharmacological and psychological treatment in older adults with an anxiety disorder that has not responded to first-line treatment is key future research to inform decision-making of clinicians and patients. An important consideration would be the enrolment of older adults who would be representative of older adults in general, i.e. those with multiple comorbid physical and mental disorders who might require polypharmacy. STUDY REGISTRATION The protocol for the systematic review is registered on PROSPERO (registration number CRD42013005612).

Abstract
OBJECTIVE Most of the existing studies investigating the impact of schizophrenia on utility have focused on the different stages of the disease. The objective of this study was to describe and quantify the impact of treatment-related side-effects on utility in patients with schizophrenia, using data from an observational study. METHODS This study used data from the European Schizophrenia Cohort (EuroSC), a multi-center 2-year cohort study conducted in France, England, and Germany. The EQ-5D questionnaire was completed every 6 months, as well as the Subjective Side Effect Rating Scale, assessing patient distress over extrapyramidal symptoms (EPS), weight gain, sedation, and sexual dysfunction, used to assess whether or not the patient experienced the side-effect. At first a bivariate analysis was conducted to describe utility values with and without side-effects. Then, a random effects regression analysis was performed on utility, where random effects were controlled for repeated measures on the same subjects, with potential confounding factors. Finally, findings were compared with those of previous publications. RESULTS This sample consisted of 1208 patients with schizophrenia. At the baseline visit, the most reported side-effect was EPS (almost 60% of patients), followed by sedation and weight gain (∼50% of patients for each), and sexual dysfunction (almost 30% of patients). Significant association with severity of symptoms, functioning abilities, and utility were found. Patients reporting none of the studied side-effects had an average EQ-5D index score of 0.81, found to be higher than scores of patients reporting EPS (0.70), sexual dysfunction (0.67), sedation (0.70), or weight gain (0.72). The random effects model reported a utility decrement of 0.042 for EPS, 0.022 for weight gain, 0.022 for sexual dysfunction, and 0.019 for sedation. Although the external validation was difficult due to the different methods or definitions of the side-effects, as well as the paucity of data for weight gain, sedation and sexual dysfunction, the results were generally consistent with previous studies. CONCLUSION This study aimed at quantifying the direct impact of main side-effects associated with antipsychotics on patients' utility. RESULTS suggested a significant direct impact of side-effects, with EPS being the most impactful.

Abstract
Bipolar disorder is a chronic episodic illness, characterized by recurrent episodes of manic or depressive symptoms. Patients with bipolar disorder frequently present first to primary care, but the diversity of the potential symptoms and a low index of suspicion among physicians can lead to misdiagnosis in many patients. Frequently, co-occurring psychiatric and medical conditions further complicate the differential diagnosis. A thorough diagnostic evaluation at clinical interview, combined with supportive case-finding tools, is essential to reach an accurate diagnosis. When treating bipolar patients, the primary care physician has an integral role in coordinating the multidisciplinary network. Pharmacologic treatment underpins both short- and long-term management of bipolar disorder. Maintenance treatment to prevent relapse is frequently founded on the same pharmacologic approaches that were effective in treating the acute symptoms. Regardless of the treatment approach that is selected, monitoring over the long term is essential to ensure continued symptom relief, functioning, safety, adherence, and general medical health. This article describes key decision-making steps in the management of bipolar disorder from the primary care perspective: from initial clinical suspicion to confirmation of the diagnosis to decision-making in acute and longer-term management and the importance of patient monitoring.

Abstract
Over the past two decades there has been increasing interest in including patients' self-reports in the management of their illness. Among the many reasons for such recent interest has been a rising consumer movement over the past few decades, which has led patients, their caregivers and their families to press for more meaningful sharing with physicians in the clinical decision-making process, with the clear expectations of better therapies and improved outcomes. Patients as consumers of services, their views, attitudes towards healthcare, as well as their level of satisfaction with care, have become increasingly recognized. The recent interest by the US Food and Drug Administration (FDA), as well as other regulatory agencies, in patient-reported outcomes (PROs) in the process of developing and testing new antipsychotics, has also added more impetus. It is clear that including patients in the decision-making process about the management of their psychiatric conditions also broadens the concept of 'recovery', by empowering patients to be active participants and gives a clear message that successful treatment in schizophrenia is more than a symptomatic improvement, but also includes improved functional status. Additionally, the recent interest in personalized medicine puts the patient in the centre of such development. Since 2004, when we published our review about the impact of new antipsychotics on quality of life in CNS Drugs, a number of newer antipsychotics have been introduced and include ziprasidone, aripiprazole, paliperidone, asenapine, iloperidone and lurasidone. The current review is based on 31 selected publications that cover the years 2004-2012, and deals with the impact of such newer antipsychotics on specific domains of PROs, such as subjective tolerability, quality of life, medication preference, satisfaction and social functioning. Most of the available data deal with ziprasidone, aripiprazole and paliperidone. Though the great majority of the studies indicate the newer antipsychotics have favourably impacted on aspects of PROs, such a conclusion can only be considered a trend due to the many design and methodological limitations of many of these studies. It is interesting to note, as the field awaits more rigorous studies, that there seems to be a unifying core that exists among the various subjective outcomes and that tends to generalize from one subjective outcome to other subjective outcomes. The patient who experiences good subjective tolerability to medications tends generally to be more satisfied and has a strong medication preference. The identification of such a unifying core can prove helpful, not only in the development of appropriate scales, but also in informing and guiding the process of development of new antipsychotics.

Abstract
BACKGROUND Generalized anxiety disorder (GAD) is one of the most prevalent anxiety disorders, with important implications for patients and healthcare resources. However, few economic evaluations of pharmacological treatments for GAD have been published to date, and those available have assessed only a limited number of drugs. OBJECTIVE To assess the cost effectiveness of pharmacological interventions for patients with GAD in the UK. METHODS A decision-analytic model in the form of a decision tree was constructed to compare the costs and QALYs of six drugs used as first-line pharmacological treatments in people with GAD (duloxetine, escitalopram, paroxetine, pregabalin, sertraline and venlafaxine extended release [XL]) and 'no pharmacological treatment'. The analysis adopted the perspective of the NHS and Personal Social Services (PSS) in the UK. Efficacy data were derived from a systematic literature review of double-blind, randomized controlled trials and were synthesized using network meta-analytic techniques. Two network meta-analyses were undertaken to assess the comparative efficacy (expressed by response rates) and tolerability (expressed by rates of discontinuation due to intolerable side effects) of the six drugs and no treatment in the study population. Cost data were derived from published literature and national sources, supplemented by expert opinion. The price year was 2011. Probabilistic sensitivity analysis was conducted to evaluate the underlying uncertainty of the model input parameters. RESULTS Sertraline was the best drug in limiting discontinuation due to side effects and the second best drug in achieving response in patients not discontinuing treatment due to side effects. It also resulted in the lowest costs and highest number of QALYs among all treatment options assessed. Its probability of being the most cost-effective drug reached 75 % at a willingness-to-pay threshold of £20,000 per extra QALY gained. CONCLUSION Sertraline appears to be the most cost-effective drug in the treatment of patients with GAD. However, this finding is based on limited evidence for sertraline (two published trials). Sertraline is not licensed for the treatment of GAD in the UK, but is commonly used by primary care practitioners for the treatment of depression and mixed depression and anxiety.

Abstract
The Canadian Network for Mood and Anxiety Treatments published guidelines for the management of bipolar disorder in 2005, with updates in 2007 and 2009. This third update, in conjunction with the International Society for Bipolar Disorders, reviews new evidence and is designed to be used in conjunction with the previous publications.The recommendations for the management of acute mania remain largely unchanged. Lithium, valproate, and several atypical antipsychotic agents continue to be first-line treatments for acute mania. Monotherapy with asenapine, paliperidone extended release (ER), and divalproex ER, as well as adjunctive asenapine, have been added as first-line options.For the management of bipolar depression, lithium, lamotrigine, and quetiapine monotherapy, as well as olanzapine plus selective serotonin reuptake inhibitor (SSRI), and lithium or divalproex plus SSRI/bupropion remain first-line options. Lurasidone monotherapy and the combination of lurasidone or lamotrigine plus lithium or divalproex have been added as a second-line options. Ziprasidone alone or as adjunctive therapy, and adjunctive levetiracetam have been added as not-recommended options for the treatment of bipolar depression. Lithium, lamotrigine, valproate, olanzapine, quetiapine, aripiprazole, risperidone long-acting injection, and adjunctive ziprasidone continue to be first-line options for maintenance treatment of bipolar disorder. Asenapine alone or as adjunctive therapy have been added as third-line options.

Abstract
INTRODUCTION Asenapine is a sublingually administered second-generation antipsychotic with proven efficacy for the treatment of moderate to severe manic episodes associated with bipolar I disorder in adults. Its relatively favorable weight and metabolic profile, as well as the lack of appreciable activity at muscarinic cholinergic receptors and the sublingual administration are of clinical interest. AREAS COVERED This paper comprises a review and commentary regarding the use of sublingual asenapine in the treatment of acute manic and mixed episodes of bipolar disorder. Basic principles in dosing, switching, management of side effects and co-administration with other medications are provided. EXPERT OPINION Asenapine displays quick and reliable effects on manic symptoms, very low risk of depressive switches, efficacy on depressive symptoms during manic and mixed episodes, usually good tolerability and continued longer-term efficacy on residual and subthreshold symptoms. The fast-dissolving sublingual route of administration may favor those who have difficulties in swallowing medications. Also, the sublingual administration reduces the risk of overdose when more than the prescribed tablets are swallowed. The relatively low metabolic risk and the lack of anticholinergic side effects contribute to making this medication a useful tool for the treatment of patients with bipolar disorder.

Abstract
OBJECTIVES To identify published closed-loop Bayesian mixed treatment comparisons (MTCs) and to summarise characteristics regarding their conduct and reporting. DESIGN Systematic review. METHODS We searched multiple bibliographic databases (January 2006-31 July 2011) for full-text, English language publications of Bayesian MTCs comparing the effectiveness or safety of ≥3 interventions based on randomised controlled trials and having at least one closed loop. Methodological and reporting characteristics of MTCs were extracted in duplicate and summarised descriptively. RESULTS We identified 34 Bayesian MTCs spanning 13 clinical areas. Publication of MTCs increased over the 5-year period; with 76.5% published during or after 2009. MTCs included a mean (±SD) of 35.9±30.1 trials (n=33 459±71 233 participants) and 8.5±4.3 interventions (85.7% pharmacological). Non-informative and informative prior distributions were reported to be used in 44.1% and 8.8% of MTCs, respectively, with the remainder failing to specify the prior used. A random-effects model was used to analyse the networks of trials in 58.5% of MTCs, all using WinBUGS; however, code was infrequently provided (20.6%). More than two-thirds of MTCs (76.5%) also conducted traditional meta-analysis. Methods used to evaluate convergence, heterogeneity and inconsistency were infrequently reported, but from those providing detail, methods appeared varied. MTCs most often used a binary effect measure (85.3%) and ranking of interventions based on probability was common (61.8%), although rarely displayed in a figure (8.8% of MTCs). MTCs were published in 24 different journals with a mean impact factor of 9.20±8.71. While 70.8% of journals imposed limits on word counts and 45.8% limits on the number of tables/figures, online supplements/appendices were allowed in 79.2% of journals. Publication of closed-loop Bayesian MTCs is increasing in frequency, but details regarding their methodology are often poorly described. Efforts in clarifying the appropriate methods and reporting of Bayesian MTCs should be of priority.

Abstract
Bipolar disorder is a prevalent disorder that tends to become progressive without treatment and with inadequate treatment. Second generation (atypical) antipsychotic drugs have increasingly been used as adjunctive treatment or monotherapy for mania, but they have the potential for significant adverse effects and their role in maintenance treatment remains unclear. Asenapine is a new atypical antipsychotic medication formulated in a sublingual preparation that has been studied for mania but not maintenance therapy. Evidence indicating efficacy, adverse effects, and potential benefits and drawbacks of using asenapine in the treatment of bipolar disorder based on currently available published data are summarized.

Abstract
Ziprasidone is a second generation (“atypical”) antipsychotic drug that has been used alone and as an adjunct to standard mood stabilizers to reduce recurrence rates in bipolar disorder. Approval of ziprasidone as an adjunct to lithium or valproate in 2009 was based on an industry sponsored study of 584 outpatients with a current or recent manic episode; 240 of these subjects were randomized to adjunctive ziprasidone or placebo and 138 completed a six month trial. Patients enrolled in maintenance studies did not have refractory mood disorders, comorbid conditions or risk of dangerousness. Maintenance ziprasidone augmentation is an option for patients who do not respond to a single mood stabilizer rapidly, and possibly for those with residual psychotic symptoms, but there are insufficient data to prefer this approach to combinations of mood stabilizers or augmentation with other agents. Ziprasidone is generally well tolerated, with less sedation and weight gain than many other antipsychotic drugs; it should be taken with food. Primary interactions of concern are with other serotonergic medications, MAO inhibitors, and other medications that prolong the QT interval.

Abstract
INTRODUCTION Limited information is available on the clinical issues and strategies for optimal clinical usage of ziprasidone in the treatment of adult patients with acute manic or mixed episodes of bipolar disorder. AREAS COVERED To address those issues, information from clinical trials addressing the efficacy and tolerability of ziprasidone in acute bipolar mania was reviewed and supplemented with the input from an expert faculty of European psychiatrists with extensive experience in treating patients with bipolar mania, both in clinical trials and in everyday clinical practice. EXPERT OPINION Effective use of oral ziprasidone in the treatment of acute bipolar mania requires rapid titration to doses in the range 120 - 160 mg/day and administration with meals of ≥ 500 kcal. As in the clinical trials, temporary short-term use of benzodiazepines (in particular lorazepam for agitation or temazepam for insomnia) could be advisable. Available evidence from randomized clinical trials in combination with clinical experience supports the use of ziprasidone as one of the first-line effective and safe treatments for acute manic or mixed episodes associated with bipolar I disorder.

Abstract
BACKGROUND The second generation antipsychotics now have clinical approvals for the treatment of schizophrenia, bipolar depression, bipolar mania, autism, major depressive disorder and are used furthermore off-label to treat other mental disorders. Each agent is unique in its pharmacodynamic profile and allows for unique dosing strategies to be employed when treating these different disorders. AIMS To review relevant data regarding the second generation antipsychotics and their empirical dosing strategies. To further review and comment theoretically in these areas where substantial, definitive data are lacking. MATERIALS AND METHODS A MEDLINE and recent textbook review was conducted regarding each second generation antipsychotic and cross-referenced with searches for major mental disorders. The findings are compiled in the review below. DISCUSSION The second generation antipsychotics are clearly delineated in the treatment of psychosis and mania and share similar mechanisms of action to achieve these results: dopamine-2 receptor antagonism for efficacy and serotonin-2a receptor antagonism for EPS tolerability. From here, each agent has a unique pharmacodynamic and pharmacokinetic profile where some agents carry more, or less antidepressant, anxiolyic, or hypnotic profiles. Choosing an agent, and dosing it in low, middle, or high ranges may result in differential effectiveness and tolerability. CONCLUSION The second generation antipsychotics have many clinical applications in psychiatric practice. This article serves to review this and also suggests ways clinicians may optimize treatment based upon patient diagnosis and utilizing appropriate dosing of each individual second generation antipsychotic.

Abstract
There is substantial preclinical and clinical evidence to suggest a potential role for the dopamine D₃ receptor in the treatment of schizophrenia. ABT-925 is a selective dopamine D₃ receptor antagonist with an approximately 100-fold higher in vitro affinity for dopamine D₃ versus D₂ receptors. This double-blind, randomized, placebo-controlled, escalating-dose, parallel-group study assessed the efficacy and safety of ABT-925 in the treatment of patients with acute exacerbation of schizophrenia. One hundred fifty-five patients were assessed over a 6-week double-blind treatment period (placebo: n = 48; ABT-925 50 mg once daily [QD]: n = 53; ABT-925 150 mg QD: n = 54). The primary efficacy measure was mean change from baseline to final evaluation on the Positive and Negative Syndrome Scale total score. Secondary measures of efficacy and pharmacokinetic parameters were also assessed. Safety assessments included adverse event monitoring, laboratory tests, vital signs, movement rating scales, and electrocardiogram measures. No statistically significant treatment effect was observed with ABT-925 50 mg QD or 150 mg QD compared with placebo on primary or secondary efficacy end points. Pharmacokinetic parameter estimates increased with dose in a linear fashion. ABT-925 50 mg QD and 150 mg QD were generally well tolerated, with adverse event profiles similar to that of placebo. Findings from a concurrent positron emission tomography study among healthy volunteers suggest that the ABT-925 doses used in this study may not have been sufficient to adequately occupy D₃ receptors, thereby underscoring the importance of pharmacodynamic markers, such as PET, in determining appropriate compound doses before embarking on studies in a target population.

Abstract
BACKGROUND Perception of quality of life may differ depending on the perspective. The aim of the study was to assess the psychometric properties of the Spanish version of the 'TOlerability and quality Of Life' (TOOL) questionnaire, a specific self-rated instrument to evaluate the impact of side effects of antipsychotic drugs on health-related quality of life (HRQoL). The questionnaire consists of eight items answered on a four-point Likert scale. METHODS A psychometric study was conducted with clinically stable outpatients with schizophrenia and bipolar disorder under antipsychotic treatment. The translation and cultural adaptation of the questionnaire was performed according to international standards. Internal consistency using the Cronbach α coefficient and test-retest reliability using the intraclass correlation coefficient (ICC) was used to assess the reliability of the instrument. Patients completed generic and specific measures of quality of life and clinical severity. RESULTS A total of 238 patients were analysed, with a mean age of 42 years (SD 10.9). The mean completion time was 4.9 min (SD 4.4). Internal consistency and intraclass correlation coefficient were adequate (Cronbach α = 0.757 and ICC = 0.90). Factorial analysis showed a unidimensional structure (a single eigenvalue >1, accounting for 39.1% of variance). Significant Spearman's rank correlations between the TOOL and both generic and specific measures were found. The questionnaire was able to discriminate among the Clinical Global Impression - Severity scores (Mann-Whitney U test, P < 0.001). CONCLUSIONS The TOOL questionnaire shows appropriate feasibility, reliability, and discriminative performance as a patient-reported outcome. TOOL constitutes a valuable addition to measure the impact of adverse events of antipsychotic drugs from the patient perspective.

Abstract
Risperidone is one of the early second-generation antipsychotics that came into the limelight in the early 1990s. Both the oral and long-acting injectable formulations have been subject to numerous studies to assess their safety, efficacy, and tolerability. Risperidone is currently one of the most widely prescribed antipsychotic medications, used for both acute and long-term maintenance in schizophrenia. Risperidone has better efficacy in the treatment of psychotic symptoms than placebo and possibly many first-generation antipsychotics. Risperidone fares better than placebo and first-generation antipsychotics in the treatment of negative symptoms. Risperidone's long acting injectable preparation has been well tolerated and is often useful in patients with medication nonadherence. Risperidone has a higher risk of hyperprolactinemia comparable to first-generation antipsychotics (FGAs) but fares better than many second-generation antipsychotics with regards to metabolic side effects. In this article, we briefly review the recent literature exploring the role of risperidone formulations in schizophrenia, discuss clinical usage, and highlight the controversies and challenges associated with its use.

Abstract
Balancing tolerability and efficacy of medications can be problematic for clinicians when assessing appropriate therapy for patients. For antipsychotic therapy, this can be especially challenging because of the hazardous movement and metabolic effects associated with them. Paliperidone is an atypical antipsychotic used for the treatment of schizophrenia and schizoaffective disorder. A systematic review of the literature for the tolerability of the drug, paliperidone, was performed. A total of 15 articles met the criteria for inclusion representing a total of 3779 patients. Data combination was conducted using the Mantel-Haenszel method, random effects model at 95% confidence. Adverse events with the greatest incidence in the paliperidone population were any treatment emergent adverse event (68%), extra-pyramidal symptoms (23%), headache (14%), insomnia (11%), somnolence (9%), tachycardia (9%) and weight gain (8%). Reported events most likely related to paliperidone [largest attributable risks (AR)] were extra-pyramidal symptoms (AR=10), reduction in acute psychosis (AR=8), any treatment emergent adverse event (AR=6), tachycardia (AR=4), and weight gain (AR=4). Events where incidence was entirely because of paliperidone (incidence equals AR) were hypersalivation (3), dysarthria (2), and sexual dysfunction (1). Reported events totally unrelated to paliperidone (AR=0) included anxiety, asthenia, constipation, depression, dyspepsia, glucose related events, and vomiting. Overall, a 50% reduction in treatment emergent psychosis was seen in schizophrenic patients treated with paliperidone, however the reduction of a psychotic event is about equal to the occurrence of an adverse event with paliperidone.
