Front Neurol 2024; 15:1356761. [PMID: 38419696 PMCID: PMC10901179 DOI: 10.3389/fneur.2024.1356761] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2023] [Accepted: 01/29/2024] [Indexed: 03/02/2024] Open
Abstract
Tardive dyskinesia (TD) is a movement disorder that can arise as a side effect of treatment with dopamine receptor-blocking agents (DRBAs), including antipsychotic drugs (APDs) used to manage psychotic illnesses. Second-generation APDs (SGAs) are often preferred to first-generation drugs due to their lower propensity to cause TD, however many SGAs-treated patients still develop the condition. Although TD is a global health concern, evidence regarding the occurrence of TD and how it is managed in Asian countries is currently limited. This article reports the results of a systematic review of the published literature on TD focusing on its prevalence, types of patients, knowledge of the condition, causative factors, and usual treatment pathways in clinical practice in Asian countries. Epidemiological data suggest that the prevalence of TD is increasing globally due to an overall rise in APD use, contributing factors being polypharmacy with multiple APDs, the use of higher than necessary doses, and off-label use for non-psychotic indications. Although exact prevalence figures for TD in Asian countries are difficult to define, there is a similar pattern of rising APD use which will result in increasing numbers of TD patients in this region. These issues need to be addressed and strategies developed to minimize TD risk and manage this disabling condition which impacts patients' quality of life and daily functioning. To date, both research into TD has been predominantly psychiatry focused and the perspectives from neurologists regarding the clinical management of this challenging condition are scarce. However, neurologists have an essential role in managing the movement disorders manifestations that characterize TD. Optimum management of TD, therefore, should ideally involve collaboration between psychiatrists and neurologists in joint care pathways, wherever practical. Collaborative pathways are proposed in this article, and the challenges that will need to be addressed in Asian countries to improve the care of people with TD are highlighted, with a focus on the neurologist's viewpoint and the implications for the management of TD globally.

Risk of Drug-induced Movement Disorders with Newer Antipsychotic Agents. Tremor Other Hyperkinet Mov (N Y) 2022; 12:19. [PMID: 35836971 PMCID: PMC9187243 DOI: 10.5334/tohm.695] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2022] [Accepted: 05/27/2022] [Indexed: 01/19/2023] Open
Abstract
Background: The last decade has seen development of numerous novel antipsychotic drugs with unique mechanisms including long-acting formulations for clinical use. A comparative assessment of these new drugs with each other and previous antipsychotics have not been performed with regards to risk for drug-induced movement disorders (DIMD). Methods: Medline was searched from January 2010 to February 2022 for primary research articles and review articles in English using the search terms “extrapyramidal” and “tardive” with individual drug names of novel antipsychotics. Results: We identified articles describing the risk of DIMD with 6 novel antipsychotics, 4 novel formulations, and 3 experimental antipsychotics. Both short- and long-term data generally showed comparable to lower risk of DIMD with novel antipsychotics and recent long-acting formulations compared to previously marketed antipsychotics. Discussion: Several novel antipsychotics, particularly lumateperone and pimavanserin, show promise in being able to treat psychosis while reducing the risk of DIMD. Long-acting paliperidone may reduce risk of DIMD while other long-acting injectable formulations of SGA have similar risk of DIMD compared to oral formulations. New drug targets for treating psychosis without dopamine blockade also show promise.

Abstract
OBJECTIVE The aim of this study was to evaluate demographic, clinical, and treatment factors that may impact on neurological adverse effects in naive and quasi-naive children and adolescents treated with antipsychotics. METHODS This was a 1-year, multicenter, observational study of a naive and quasi-naive pediatric population receiving antipsychotic treatment. Two subanalyses were run using the subsample of subjects taking the 3 most used antipsychotics and the subsample of antipsychotic-naive subjects. Total dyskinesia score (DyskinesiaS) and total Parkinson score (ParkinsonS) were calculated from the Maryland Psychiatric Research Center Involuntary Movement Scale, total UKU-Cognition score was calculated from the UKU Side Effect Rating Scale. Risk factors for tardive dyskinesias (TDs) defined after Schooler-Kaine criteria were studied using a logistic regression. RESULTS Two hundred sixty-five subjects (mean age, 14.4 [SD, 2.9] years) with different Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Axis I disorders were recruited. DyskinesiaS (P < 0.001) and ParkinsonS (P < 0.001) increased at 1-year follow-up. Risperidone was associated with higher increases in DyskinesiaS compared with quetiapine (P < 0.001). Higher increases in ParkinsonS were found with risperidone (P < 0.001) and olanzapine (P = 0.02) compared with quetiapine. Total UKU-Cognition Score decreased at follow-up. Findings were also significant when analyzing antipsychotic-naive subjects. Fifteen subjects (5.8%) fulfilled Schooler-Kane criteria for TD at follow-up. Younger age, history of psychotic symptoms, and higher cumulative exposure time were associated with TD at follow-up. CONCLUSIONS Antipsychotics increased neurological adverse effects in a naive and quasi-naive pediatric population and should be carefully monitored. Risperidone presented higher scores in symptoms of dyskinesia and parkinsonism. Quetiapine was the antipsychotic with less neurological adverse effects. Younger subjects, psychosis, and treatment factors predicted an increased risk of TD.

Abstract
Tardive dyskinesia (TD) is a serious, disabling and potentially permanent, neurological hyperkinetic movement disorder that occurs after months or years of taking dopamine receptor-blocking agents. The pathophysiology of TD is complex, multifactorial and still not fully understood. Although there is no identified effective and standard treatment for TD, several agents have been tried for the management of this motor disturbance. The aim of this case series is to review the literature in regard to the identification, diagnosis and the treatment of TD with anticholinergics, anticholinergic medication withdrawal, cholinergic agents, botulinum toxin intramuscular injections, tetrabenazine, levetiracetam, propranolol and zolpidem, and to describe one case of TD that responded favorably to clonazepam and two cases of TD that responded favorably to Ginkgo biloba.

Abstract
BACKGROUND To assess the tardive dyskinesia (TD) rate in studies of once-monthly long-acting injectable (LAI) paliperidone palmitate (PP) and once-daily oral paliperidone extended release (Pali ER). METHODS Completed schizophrenia and bipolar studies for PP and Pali ER (≥ 6 month duration with retrievable patient-level data) were included in this post hoc analysis. Schooler-Kane research criteria were applied using Abnormal Involuntary Movement Scale (AIMS) scores to categorise probable (qualifying AIMS scores persisting for ≥ 3 months) and persistent TD (score persisting ≥ 6 months). Spontaneously reported TD adverse events (AEs) were also summarised. Impact of exposure duration on dyskinesia (defined as AIMS total score ≥ 3) was assessed by summarising the monthly dyskinesia rate. RESULTS In the schizophrenia studies, TD rates for PP (four studies, N = 1689) vs. Pali ER (five studies, N = 2054), were: spontaneously reported AE, 0.18% (PP) vs. 0.10% (Pali ER); probable TD, 0.12% (PP) vs. 0.19% (Pali ER) and persistent TD, 0.12% (PP) vs. 0.05% (Pali ER). In the only bipolar study identified [Pali ER (N = 614)], TD rate was zero (spontaneously reported AE reporting, probable and persistent TD assessments). Dyskinesia rate was higher within the first month of treatment with both PP (13.1%) and Pali ER (11.7%) and steadily decreased over time (months 6-7: PP: 5.4%; Pali ER: 6.4%). Mean exposure: PP, 279.6 days; Pali ER, 187.2 days. CONCLUSIONS Risk of TD with paliperidone was low (< 0.2%), regardless of the formulation (oral or LAI), in this clinical trial dataset. Longer cumulative exposure does not appear to increase the risk of dyskinesias.

Abstract
OBJECTIVE To review the evidence for the role of long-acting injectable (LAI) antipsychotics (APs), especially the second-generation AP (SGA) LAIs, in the treatment of schizophrenia and to discuss the use rates of LAIs in Canada. METHOD A search of online medical databases was conducted of the published literature (1995-2012) of the effects of LAIs on the domains of remission, adherence, relapse, and hospitalization. Results obtained from randomized controlled trials (RCTs), systematic reviews, meta-analyses, and large-scale observational studies were included. Expert consensus data were also solicited on LAI use within a Canadian context. RESULTS While the efficacy of LAIs, compared with placebo, is well established, the evidence from RCTs is equivocal for any specific advantage for SGA LAIs, compared with oral medications, probably owing to challenges in conducting such RCTs. Evidence from methodologically less rigorous studies and from clinical practice suggests some advantages in achieving and maintaining remission, risk of relapse, and hospitalization. The rate of LAI (first-generation AP and SGA) use from published outpatient studies is low at 6.3% in Canada, compared with 15% to 80% worldwide. However, there is a relatively high rate of use in specific early psychosis programs and in conjunction with community treatment orders in Canada. CONCLUSIONS LAIs are at least as effective as oral APs in the treatment of psychotic disorders. The former may have specific advantages for patients who demonstrate covert nonadherence. The underuse of LAIs in Canada needs to be better understood and addressed.

Abstract
BACKGROUND Current guidelines suggest specific criteria for oral or long-acting injectable antipsychotic drugs (LAIs). This review aims to describe the demographic and clinical characteristics of the ideal profile of the patient with schizophrenia treated with LAIs, through the analysis of nonrandomized studies. METHODS A systematic review of nonrandomized studies in English was performed attempting to analyze the factors related to the choice and use of LAIs in daily practice. The contents were outlined using the Cochrane methods for nonrandomized studies and the variables included demographic as well as clinical characteristics. The available literature did not allow any statistical analysis that could be used to identify the ideal profile of patients with schizophrenia to be treated with LAIs. RESULTS Eighty publications were selected and reviewed. Prevalence of LAI use ranged from 4.8% to 66%. The only demographic characteristics that were consistently assessed through retrieved studies were age (38.5 years in the 1970's, 35.8 years in the 1980's, 39.3 years in the 1990's, to 39.5 years in the 2000's) and gender (male > female).Efficacy was assessed through the use of various symptom scales and other indirect measurements; safety was assessed through extrapyramidal symptoms and the use of anticholinergic drugs, but these data were inconsistent and impossible to pool. Efficacy and safety results reported in the different studies yielded a good therapeutic profile with a maximum of 74% decrease in hospital admissions and the prevalence of extrapyramidal symptoms with LAIs consistently increased at 6, 12, 18, and 24 months (35.4%, 37.1%, 36.9%, and 41.3%, respectively). CONCLUSIONS This analysis of the available literature strongly suggests that further observational studies on patients with schizophrenia treated with LAIs are needed to systematically assess their demographic and clinical characteristics and the relationships between them and patient outcome.Besides the good efficacy and safety profile of LAIs, health care staff must also take into account the importance of establishing a therapeutic alliance with the patient and his/her relatives when selecting the most appropriate treatment. LAIs seem to be a good choice not only because of their good safety and efficacy profile, but also because they improve compliance, a key factor to improving adherence and to establishing a therapeutic alliance between patients with schizophrenia, their relatives, and their health care providers.

Abstract
OBJECTIVE To model the cost effectiveness of paliperidone palmitate (paliperidone long-acting injectable; PLAI), a new once-monthly long-acting antipsychotic therapy, compared with risperidone long-acting injectable (RLAI) and olanzapine pamoate (OLAI), in multi-episode patients (two or more relapses) with schizophrenia in Sweden. METHODS A Markov decision analytic model was developed to simulate the history of a cohort of multi-episode patients transitioning through different health states on a monthly basis over a 5-year time horizon from the perspective of the Swedish healthcare system. Therapeutic strategies consisted of starting treatment with RLAI (mean dose 37.5 mg every 2 weeks), PLAI (mean dose 75 mg equivalent (eq.) every month) or OLAI (150 mg every 2 weeks or 300 mg every 4 weeks). Probability of relapse, level of adherence, side-effects (extrapyramidal symptoms, tardive dyskinesia, weight gain and diabetes) and treatment discontinuation (switch) were derived from long-term observational data when feasible. Incremental cost-effectiveness outcomes, discounted at 3% annually, included cost per quality-adjusted life-year (QALY) and cost per relapse avoided (expressed in 2009 Swedish Krona SEK). RESULTS Relative to RLAI and OLAI, PLAI is economically dominant: more effective (additional QALYs, less relapses) and less costly treatment option over a 5-year time horizon. The results were robust when tested in sensitivity analysis. LIMITATIONS The impact of once-monthly treatment on adherence levels is not yet known, and not all variables that could impact on real-world outcomes and costs were included in this model. CONCLUSION PLAI was cost saving from a Swedish payer perspective compared with RLAI and OLAI in the long-term treatment of multi-episode (two or more relapses) schizophrenia patients.

Abstract
BACKGROUND We analyzed data retrieved through a PubMed search of randomized, placebo-controlled trials of first-generation antipsychotic long-acting injectables (haloperidol decanoate, bromperidol decanoate, and fluphenazine decanoate), and a company database of paliperidone palmitate, to compare the benefit-risk ratio in patients with schizophrenia. METHODS From the eight studies that met our selection criteria, two efficacy and six safety parameters were selected for calculation of number needed to treat (NNT), number needed to harm (NNH), and the likelihood of being helped or harmed (LHH) using comparisons of active drug relative to placebo. NNTs for prevention of relapse ranged from 2 to 5 for paliperidone palmitate, haloperidol decanoate, and fluphenazine decanoate, indicating a moderate to large effect size. RESULTS Among the selected maintenance studies, NNH varied considerably, but indicated a lower likelihood of encountering extrapyramidal side effects, such as akathisia, tremor, and tardive dyskinesia, with paliperidone palmitate versus placebo than with first-generation antipsychotic depot agents versus placebo. This was further supported by an overall higher NNH for paliperidone palmitate versus placebo with respect to anticholinergic use and Abnormal Involuntary Movement Scale positive score. LHH for preventing relapse versus use of anticholinergics was 15 for paliperidone palmitate and 3 for fluphenazine decanoate, favoring paliperidone palmitate. CONCLUSION Overall, paliperidone palmitate had a similar NNT and a more favorable NNH compared with the first-generation long-acting injectables assessed.

Abstract
BACKGROUND Second-generation antipsychotics (SGAs) represent an advance in the long-term management of schizophrenia. AIMS To review the available evidence concerning SGA long-acting injections (LAIs). METHOD A systematic review of the literature was conducted using PubMed. RESULTS Risperidone long-acting injection was the first licensed SGA-LAI compound and is effective in the long-term management of schizophrenia, with a safety profile similar to that of oral risperidone. Olanzapine pamoate has recently been approved in Europe. In terms of efficacy, at injection intervals of up to 4 weeks it appears comparable to oral olanzapine, although the potential for ;post-injection syndrome' (delirium) calls for additional safety considerations. Paliperidone palmitate is currently under review with the licensing authorities. It also affords the potential advantage of monthly dosing. CONCLUSIONS More long-term comparisons of SGA-LAIs with oral SGAs as well as with first-generation antipsychotic LAIs are needed. These studies should include cost-effectiveness data.

Abstract
BACKGROUND Depot antipsychotics are widely used in clinical practice. Long-acting formulations of second-generation antipsychotics are now being developed and introduced. AIMS To review the pharmacology, pharmacokinetics and adverse effect profiles of currently available antipsychotic long-acting injections (LAIs). METHOD The psychopharmacological properties of first- and second-generation antipsychotic LAIs are reviewed using data available up to October 2008. RESULTS First-generation antipsychotic (FGA) LAIs are associated with a high rate of acute and chronic movement disorders. Risperidone LAI is better tolerated in this respect, but is associated with hyperprolactinaemia and weight gain. Olanzapine LAI causes weight gain and other metabolic effects but appears not to be associated with an important incidence of movement disorders. CONCLUSIONS Dosing of LAIs is complicated by delayed release of drug, changes in plasma levels without change in dose, and by the lack of data establishing clear dose requirements. All LAIs offer the prospect of assured adherence (although patients may still default on treatment) but their use is complicated by adverse effects, complex pharmacokinetics and confusion over dose-response relationships.

Abstract
IMPORTANCE OF THE FIELD It is very rare for patients with bipolar disorder to have a single episode of mania or depression over a lifetime and the vast majority of these individuals need long-term prophylactic/maintenance treatment. However, treatment nonadherence is a major issue for close to half of subjects with bipolar disorder who are prescribed medications. Risperidone long-acting injection (LAI) has proven efficacious for the maintenance phase of bipolar disorder and may mitigate the problem of nonadherence in the substantial group of patients for whom this is a significant concern. AREAS COVERED IN THIS REVIEW This paper comprises a review and commentary regarding the use of risperidone LAI in bipolar disorder. WHAT THE READER WILL GAIN The reader will gain an understanding regarding the risks and benefits of risperidone LAI in bipolar disorder. We review the available evidence and discuss the strengths and weaknesses of published studies, providing an opinion about the clinical usefulness of risperidone LAI as well as suggestions for future research. TAKE HOME MESSAGE The use of risperidone LAI, through improved adherence, has the potential to ameliorate the course of bipolar disorder.

Abstract
The study aimed to evaluate the efficacy of long-acting injectable risperidone (LAR) in Asian patients with schizophrenia spectrum disorders. Twenty-five patients enrolled in this 6-month open labelled study. They were switched from their current antipsychotic to LAR without a prior oral risperidone run-in phase. Efficacy was assessed by the positive and negative syndrome scale (PANSS) and clinical global impression (CGI) scales. Extra-pyramidal side effects (EPSE) was assessed using the Simpson Angus Scale (SAS), and weight and plasma levels of fasting blood glucose, lipids and prolactin were measured. Baseline and last visits differences were tested by paired t-test and Wilcoxon signed-rank test; ratings measured over time were analysed using repeated measures ANOVA. Participants' mean age was 30.3 (+/-6.6) years. Principal reason for switching to LAR was non-compliance (40.0%). Thirteen (52%) patients completed the trial. Over 6 months, there were significant reductions in total PANSS (p = 0.008) and CGI (p = 0.001) scores. There were significant increases in weight (p < 0.001), levels of plasma cholesterol and fasting glucose. LAR was effective in improving symptom severity within the first month of starting treatment. However, significant increases in weight and plasma levels of fasting glucose and cholesterol raise concern about metabolic side effects.

Abstract
A long-acting form of the second-generation antipsychotic drug risperidone is now broadly available for the treatment of schizophrenia and closely related psychiatric conditions. It combines the advantage of previously available depot formulations for first-generation drugs with the favorable characteristics of the modern "atypical" antipsychotics, namely higher efficacy in the treatment of the negative symptoms of schizophrenia and reduced motor disturbances. Published clinical studies show an objective clinical efficacy (as per psychiatric symptom scores and relapse data) that exceeds that of oral atypical antipsychotics when patients are switched to the long-acting injectable form, a low incidence of treatment-emergent extrapyramidal side effects, and very good acceptance by patients. Available data for maintenance treatment of bipolar disorder show equivalence with the oral form instead of superiority, but are still limited. As it seems likely that efficacy benefits are mostly due to the fact that the injectable form reduces the demand for patient compliance to one physician visit every 2 weeks instead of self-administration on a daily or twice-daily basis, additional potential could exist in other psychiatric disorders where atypical antipsychotic drugs are of benefit but where patient adherence to treatment schedules is typically low.

Abstract
PURPOSE OF REVIEW To provide an update on tardive dyskinesia rates in patients treated with first-generation or second-generation antipsychotics in studies published since the last systematic review in 2004. RECENT FINDINGS Across 12 trials (n = 28 051, age 39.7 years, 59.7% male, 70.9% white, followed for 463 925 person-years), the annualized tardive dyskinesia incidence was 3.9% for second-generation antipsychotics and 5.5% for first-generation antipsychotics. Stratified by age, annual tardive dyskinesia incidence rates were 0.35% with second-generation antipsychotics in children, 2.98% with second-generation antipsychotics versus 7.7% with first-generation antipsychotics (P < 0.0001) in adults, and 5.2% with second-generation antipsychotics versus 5.2% with first-generation antipsychotics (P = 0.865) in the elderly (based almost exclusively on one retrospective cohort study). In four adult studies (n = 2088, age 41.2 years, 71.2% male, 62.0% white), tardive dyskinesia prevalence rates were 13.1% for second-generation antipsychotics, 15.6% for antipsychotic-free patients, and 32.4% for first-generation antipsychotics (P < 0.0001). SUMMARY Current evidence supports a lower tardive dyskinesia risk for second-generation antipsychotics than for first-generation antipsychotics. Tardive dyskinesia incidence was higher with second-generation antipsychotics than previously reported, possibly due to recent studies with relatively short mean durations and use of nonstandard tardive dyskinesia definitions.

Child Adolesc Psychiatry Ment Health 2007; 1:3. [PMID: 17683634 PMCID: PMC1939834 DOI: 10.1186/1753-2000-1-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2007] [Accepted: 06/26/2007] [Indexed: 11/26/2022] Open
Abstract
BACKGROUND Movement disorders (MD) in children are relatively common and may be associated with medication use. Objective methods (ie rating scales) and specific research criteria may be helpful in identifying MD-related adverse events that would otherwise not be apparent from spontaneous reports. We assessed whether more stringent and rigorous criteria would provide MD rates similar to those derived subjectively from spontaneous reports. METHODS MDs were assessed in children with disruptive behavior disorders (DBDs) and subaverage intelligence receiving risperidone. Data were from three 1-year, open-label studies in subjects 4-14 years old. Dyskinesia severity was rated by the Extrapyramidal Symptom Rating Scale (ESRS) dyskinesia subscale. Tardive dyskinesia (TD) was defined: mild dyskinesia (scores 2, 3) in two anatomical areas; or moderate dyskinesia (score >or= 4) in one area for >or= 4 weeks in subjects without dyskinesia at baseline (scores 0, 1). RESULTS The mean (+/- SD) age of subjects was 9.4 +/- 2.4 years, the mean (+/- SD) risperidone dose was 1.6 +/- 0.7 mg/day, and the mean (+/- SD) exposure was 317.8 +/- 104.5 days. ESRS data were available for 668 subjects. Mean ESRS scores were low throughout the study. At baseline, 655 subjects had no dyskinetic symptoms. One subject met predefined TD criteria after a risperidone dose reduction. Symptoms persisted for 4 weeks, resolving with continued treatment and no dosage change. Two different subjects had TD by spontaneous adverse-event reports, with dyskinetic symptoms at 1-2 visits, and symptoms that resolved after treatment discontinuation. Thirteen subjects had dyskinesia at baseline; their mean ESRS dyskinesia scores decreased at endpoint. CONCLUSION Using objective rating scales and research criteria, low-dose risperidone was associated with low risk of TD and other MDs in children with DBDs in three large 1-year studies. Careful, objective evaluation of emergent MDs during all stages of treatment is essential for identifying treatment-emergent TD.

Abstract
Clinically important differences exist between antipsychotic agents and formulations in terms of safety and tolerability. Features of the biochemical interaction between the antipsychotic and the D2-receptor may underlie these differences. This article reviews current information on the relationship between antipsychotic receptor occupancy and clinical response. A literature search was performed using the keywords 'antipsychotic or neuroleptic', 'receptor' and 'occupancy' and 'dopamine' and 'D2' supplemented by the authors' knowledge of the literature. Imaging and clinical data have generally supported the hypotheses that optimal D2-receptor occupancy in the striatum lies in a 'therapeutic window' between approximately 65 and approximately 80%, however, pharmacokinetic and pharmacodynamic properties of a drug should also be taken into account to fully evaluate its therapeutic effects. Additional research, perhaps in preclinical models, is needed to establish D2-receptor occupancy in various regions of the brain and the optimal duration of D2-receptor blockade in order to maximise efficacy and tolerability profiles of atypical antipsychotics and thereby improve treatment outcomes for patients with schizophrenia.

Abstract
OBJECTIVE To review the pharmacokinetics, efficacy, safety, and cost-effectiveness of long-acting risperidone. METHODS Studies published between January 2000 and October 2006 evaluating the pharmacokinetics, efficacy, safety, and cost-effectiveness of long-acting risperidone were reviewed, as identified from literature searches using Medline and EMBASE. Abstracts and posters on long-acting risperidone presented at key psychiatry congresses and available in the public domain during this time period were also reviewed. RESULTS The unique pharmacokinetic profile of long-acting risperidone is derived from the encapsulation of risperidone in a glycolide/lactide matrix in the form of microspheres such that after a single intramuscular injection, significant plasma levels of the drug are achieved after week 3. Steady state, after repeated administration at 2-week intervals, is achieved after 3 injection cycles. Short- and long-term studies have demonstrated that long-acting risperidone (25, 37.5, or 50 mg) is both efficacious and well tolerated in a wide variety of patients with schizophrenia and related psychoses. Most patients can be switched from other oral and long-acting antipsychotic agents without compromising efficacy and safety. Long-acting risperidone may also reduce overall healthcare costs by decreasing rates of relapse and hospitalization. CONCLUSION The assured delivery of an atypical antipsychotic medication with long-acting risperidone has important implications for patient compliance, maintenance of stability, consistency of treatment, and improving patient outcomes including the achievement of remission.

Abstract
Schizophrenia remains a severe disorder that is associated with a poor outcome in a large subgroup of patients. Major efforts should be made to improve treatment for all patients who have this debilitating disease. Second-generation antipsychotics were a major step forward in this respect; however, important unmet needs remain, such as a better solution for frequent noncompliance problems. Depot formulations are known to have advantages in this respect. However, for a long time, only depot formulations of conventional antipsychotics were available, with their high risk of extrapyramidal adverse effects. Therefore, there has been only very restricted use of depot antipsychotics, which mainly focused on patients with chronic disease who were difficult to treat and had a high risk of noncompliance. The situation may change with the advent of a depot formulation of an atypical antipsychotic. The first depot formulation of an atypical antipsychotic to be introduced to the market is long-acting injectable risperidone. On the basis of the pharmacokinetic properties of the depot formulation, a 2-week interval between administrations is recommended. The antipsychotic efficacy of long-acting risperidone was demonstrated in two 12-week, double-blind, randomised, phase III studies, one versus placebo and the other versus oral risperidone. These two studies, together with one open-label, long-term study over 12 months, belong to the core group of trials that were relevant for the licensing of long-acting risperidone. A relapse-prevention, control group study comparing the long-acting formulation versus oral risperidone was not performed because of the known principal methodological problems of such a comparison. Instead, as much clinical data as possible was collected from observational studies that investigated questions relevant for clinical practice, such as efficacy, safety and tolerability in different subgroups, and transition from pre-treatment with different kinds of antipsychotics to long-acting risperidone. On the basis of these data, it can be stated that the efficacy of the long-term formulation of risperidone is proven, and that the safety and tolerability are more or less comparable to those of oral risperidone. The local tolerability at the injection site is good. Because it is well known that noncompliance is a frequent feature of the treatment of schizophrenia, and considering the advantages of atypical antipsychotics, consideration of whether long-acting atypical antipsychotics should have a broader indication than is the case with the depot formulations of the classical antipsychotics is warranted.

Abstract
Partial compliance with antipsychotic medications is a common and complex phenomenon that is underestimated by physicians. The consequences of partial compliance include an increased risk of relapse, rehospitalization and suicide attempts. Stigma, negative attitudes towards medications, cognitive impairment and diminished insight negatively impact treatment adherence. Oral atypical antipsychotics may improve both insight and cognitive function, but compliance with these agents is not assured. Depot conventional antipsychotics ensure medication delivery but are associated with side-effects such as EPS and dysphoria that decrease compliance. Long-acting atypicals provide significant symptom improvement, foster adherence and may help achieve improvement in insight and cognition. Addressing issues of partial and non-compliance is a significant consideration in relapse prevention strategies for patients with schizophrenia, given the devastating consequences associated with psychotic relapses.

Abstract
The management of schizophrenia patients remains one of the great challenges in psychiatry. Despite the undisputed effectiveness of antipsychotic drugs, patients and their physicians still face considerable difficulties mainly related to incomplete or lacking treatment response and the inability to predict the individual efficacy and tolerability. In this manuscript we review the key elements of pharmacological treatment of this disorder, encompassing acute and long-term management as well as specific management problems ranging from acutely violent patients to treatment-resistant subjects. Along with general treatment principles, the document provides specific information regarding efficacy and safety features of antipsychotics. Many of the currently available treatment recommendations/guidelines are based on the evidence reviewed here. This review is meant to serve as a guide for clinicians involved in managing schizophrenia, whether in a psychiatric hospital setting or as family physicians in private practice.

Abstract
BACKGROUND Although atypical antipsychotics are generally regarded as having more favorable tolerability profiles than conventional antipsychotics, differences between specific atypical agents can be important when individualizing treatment. Long-acting risperidone (LAR), the first long-acting injectable atypical anti-psychotic, has been found to be effective in the treatment of schizophrenia and schizoaffective disorder. OBJECTIVES This review summarizes clinical evidence for the tolerability profile of LAR in patients with schizophrenia and schizoaffective disorder and assesses its utility in specific patient groups, including younger patients and the elderly. METHODS MEDLINE and EMBASE were searched for studies published between January 1994 and March 2006 that evaluated the tolerability of LAR. The primary search terms were long-acting risperidone, schizophrenia, schizoaffective, long term, tolerability, and safety. Abstracts and posters presented at major psychiatry and schizophrenia conferences during this period also were reviewed. Articles were included if they were reports of clinical studies and included tolerability data for LAR. RESULTS The literature search identified 7 open-label trials, 3 double-blind trials, 15 subanalyses, and 1 pooled analysis. When patients were switched directly or indirectly from another antipsychotic agent, LAR was generally well tolerated, with a low incidence of withdrawals due to adverse events (1%-16%). Moreover, LAR was associated with a weight-gain profile of 1 to 2 kg in the short term and did not appear to negatively affect lipids or glucose metabolism. Although LAR was associated with elevations in serum prolactin levels in 2% to 7% of patients, these elevations were not symptomatic, and levels decreased over time. CONCLUSIONS LAR was generally well tolerated in several patient groups, including the elderly and those with schizoaffective disorder. When patients were switched from other antipsychotics, use of LAR was not associated with an increased risk of adverse events compared with placebo.

Abstract
BACKGROUND Risperidone is the first atypical anti-psychotic available in a long-acting injectable formulation. OBJECTIVE To provide an overview of the initial clinical experience gained with long-acting risperidone during clinical trials and in general treatment, including specific case studies, as well as providing practical advice on how to initiate treatment with this new drug. METHODS Studies published between January 2002 and June 2005 that evaluated the pharmacokinetics, efficacy and safety of long-acting risperidone for the treatment of schizophrenia were reviewed, as identified from literature searches using Medline and EMBASE. Although not peer-reviewed, abstracts and posters on long-acting risperidone presented at key psychiatry and schizophrenia congresses during this period were also reviewed where available in the public domain. RESULTS Clinical studies have consistently demonstrated that long-acting risperidone, available in dosage strengths of 25, 37.5 or 50 mg, given once every 2 weeks, is both effective and well tolerated in patients with schizophrenia. Furthermore, significant and sustained clinical improvement has been reported in patients switched to long-acting risperidone from other oral and long-acting antipsychotic agents. Several patients groups, including the young, the elderly and patients with schizoaffective disorder, have also been shown to derive significant benefit from long-acting risperidone. CONCLUSION A wide variety of patient groups may benefit from treatment with long-acting risperidone, including patients with suboptimal efficacy, particularly as a result of partial compliance, patients experiencing side-effects with another antipsychotic agent or those with a first episode of schizophrenia. Furthermore, long-acting risperidone, with its assured medication delivery, should improve patient compliance and assist patients in achieving remission, an important step towards functional recovery.
