Abstract
Treatment-resistant schizophrenia (TRS) presents considerable challenges in contemporary psychiatric practice due to inadequate response to conventional antipsychotic treatments. Paliperidone, the primary active metabolite of risperidone, particularly in its long-acting injectable (LAI) form, has emerged as a promising option for TRS due to its consistent medication delivery, reducing symptom exacerbation and relapse associated with oral dosing fluctuations. This case report presents the clinical journey of a 42-year-old female diagnosed with schizophrenia at age 15. Despite numerous hospital admissions and trials of various oral and injectable antipsychotics, including clozapine and electroconvulsive therapy (ECT), her symptoms persisted. During her last admission, her condition showed minimal improvement despite extensive pharmacological interventions. Introducing paliperidone LAI while tapering off other antipsychotics led to significant improvements within four weeks. The patient exhibited reduced hallucinatory behaviour, delusions, and disorganized behaviour. Follow-up assessments confirmed sustained progress, with the patient showing increased engagement in daily activities and reduced irritability and suspiciousness. This case underscores the potential efficacy of paliperidone LAI in managing TRS. The patient's notable improvement highlights the importance of personalized treatment plans and continuous monitoring in complex psychiatric conditions. Its favourable safety and tolerability profile further supports its use as a long-term treatment option for TRS, potentially leading to enhanced patient compliance and overall quality of life. The significant symptomatic relief and functional improvement observed advocate for the consideration of paliperidone LAI as a promising therapeutic option for TRS, with the potential to be considered in the future among the first-line treatments for TRS.

Comparative profiles of lubiprostone, linaclotide, and elobixibat for chronic constipation: a systematic literature review with meta-analysis and number needed to treat/harm. BMC Gastroenterol 2024; 24:12. [PMID: 38166671 PMCID: PMC10759335 DOI: 10.1186/s12876-023-03104-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2023] [Accepted: 12/19/2023] [Indexed: 01/05/2024] Open
Abstract
OBJECTIVE To comprehensively evaluate the efficacy, safety, patient symptoms, and quality-of-life (QoL) of lubiprostone, linaclotide, and elobixibat as treatment for chronic constipation (CC). DESIGN Systematic literature review (SLR) and meta-analysis (MA). Literature searches were conducted on PubMed and Embase using the Ovid platform. METHODS SLR including randomized controlled trials (RCTs) and observational studies was conducted to identify the overall efficacy and safety of lubiprostone, linaclotide, and elobixibat. Thereafter, MA was performed using only RCTs. The number needed to treat (NNT) and number needed to harm (NNH) analyses were additionally conducted. PRIMARY AND SECONDARY OUTCOME MEASURES The primary outcome was efficacy regarding change in spontaneous bowel movements. Secondary outcomes included safety, constipation-related symptoms, and QoL. RESULTS Twenty-four studies met the inclusion criteria for the SLR: 17 RCTs, 4 observational studies, and 3 single-arm trials. Feasibility assessment for the MA resulted in 14 studies available for safety data analysis, and 8 available for efficacy analysis, respectively. Three drugs showed similar efficacy in the MA and NNT analysis. However, the NNH analysis revealed distinct safety profiles: lubiprostone, linaclotide, and elobixibat were linked to the highest risk of nausea, diarrhea, and abdominal pain, respectively. CONCLUSION The current study provides an updated overview of the efficacy, safety, patient symptoms, and QoL of the three drugs with different mechanisms of action for CC treatment.The findings could help physicians adopt an individualized approach for treating patients with CC in clinical practice.

Abstract
Tardive dyskinesia (TD) is a heterogeneous, hyperkinetic movement disorder induced by dopamine-receptor blocking agents that presents a unique challenge in the treatment of psychosis. Although acceptance of TD as a serious consequence of antipsychotic treatment was resisted initially, subsequent research by many investigators in psychopharmacology contributed to a rich store of knowledge on many aspects of the disorder. While basic neuroscience investigations continue to deepen our understanding of underlying motor circuitry, past trials of potential treatments of TD focusing on a range of theoretical targets were often inconclusive. Development of newer antipsychotics promised to reduce the risk of TD compared to older drugs, but their improved tolerability unexpectedly enabled an expanding market that paradoxically both increased the absolute number of patients at risk and diminished attention to TD which was relegated to legacy status. Fortunately, development and approval of novel vesicular monoamine transporter inhibitors offered evidence-based symptomatic treatment of TD for the first time and rekindled interest in the disorder. Despite recent progress, many questions remain for future research including the mechanisms underlying TD, genetic predisposition, phenomenological diversity, whether new cases are reversible, how to implement best practices to prevent and treat TD, and whether the development of novel antipsychotics free of the risk of TD is attainable. We owe our patients the aspirational goal of striving for zero prevalence of persistent symptoms of TD in anyone treated for psychosis.

Benefit-Risk Analysis of Upadacitinib Compared with Adalimumab in the Treatment of Patients with Moderate-to-Severe Rheumatoid Arthritis. Rheumatol Ther 2022; 9:191-206. [PMID: 34816388 PMCID: PMC8814262 DOI: 10.1007/s40744-021-00399-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2021] [Accepted: 11/08/2021] [Indexed: 12/15/2022] Open
Abstract
INTRODUCTION Rheumatoid arthritis (RA) is a chronic autoimmune disease requiring long-term treatment. Upadacitinib (UPA), a Janus kinase (JAK) inhibitor, is a new treatment for RA. The benefit-risk profile of a medication is best understood by evaluating the number needed to treat (NNT) and the number needed to harm (NNH). This analysis evaluated the comparative risk-benefit of UPA versus adalimumab (ADA). METHODS Post-hoc analyses were performed using data from the SELECT-COMPARE trial of UPA versus placebo (PBO) and UPA versus ADA among patients with active RA who remained on stable methotrexate (MTX) treatment and had an inadequate response; patients who failed to achieve response were rescued by predefined criteria-PBO or ADA switch to UPA, and UPA switch to ADA (all patients on PBO were switched to UPA at week 26). This analysis assessed efficacy and adverse events of special interest (AESIs) at week 26, 48, and 156 (3 years). NNT and NNH (95% confidence intervals) values were calculated between UPA versus ADA for all time points, and between UPA versus PBO for week 26. NNT and NNH values were applied to a hypothetical cohort of 100 patients to estimate the comparative efficacy and safety profiles. RESULTS UPA consistently showed greater efficacy than ADA, as evidenced by NNT values < 10 for achievement of Disease Activity Score in 28 joints based on C-reactive protein (DAS28-CRP) of < 2.6 and ≤ 3.2, respectively, and functional improvement. Based on indices for disease assessment other than the DAS28-CRP, remission outcomes were higher with UPA versus ADA over 26 weeks (NNTs: 7-12), 48 weeks (NNTs: 9-16), and 156 weeks (NNTs: 9-15). With the exception of herpes zoster, other AESIs demonstrated a similar risk with UPA versus ADA. CONCLUSION In patients with active RA despite MTX use, UPA demonstrated an incremental achievement of clinical outcomes compared to ADA together with a similar profile of AESIs with ADA (with the exception of herpes zoster).

Abstract
BACKGROUND Schizophrenia is a severe psychiatric disorder. Poor medical adherence increases relapse rate. Long-acting injection of antipsychotic agent is developed for improving medical adherence. In this study, we examined the effect of paliperidone long-acting injection (PLAI) treatment in patients with schizophrenia in a real-world setting. METHODS In this retrospective cohort study, 467 patients with schizophrenia were enrolled, treated with risperidone PLAI or oral antipsychotics, and followed for 1 year. Concomitant medication, namely anticonvulsants, antidepressants, anxiolytics, sedatives or hypnotics, anticholinergics, and beta-blockers, were administered. Patients were classified into 2 groups: the LAI group (patients received LAI for treatment) and the NLAI group (patients taking only oral antipsychotics). The incidence of hospitalization, the length of hospitalization, and the incidence of emergency room visits were assessed. RESULTS The LAI group had a higher incidence of psychiatric acute ward admission (NLAI group = 4.8%; LAI = 30.3%) and emergency room visits (NLAI group = 7.3%; LAI group = 36.0%) before enrolment. During the one-year follow-up, the incidence of acute ward admission and emergency room visit did not differ in the NLAI group (P = .586 and .241) compared with before enrolment, whereas both incidences were significantly decreased in the LAI group (P < .0001 in both of them). CONCLUSIONS PLAI reduces the incidence of admission and emergency room visits.

Abstract
Recent research on second-generation long-acting injectable antipsychotics (LAI SGAs) has proven its effectiveness in minimizing medication nonadherence problem and reducing relapses. Administered by medical professionals, making quick detection of nonadherence possible, long-acting injectable antipsychotics (LAIs) facilitate immediate intervention and recovery process, and thus are favored by psychiatrists. Despite a higher initial cost with LAIs, the subsequent schizophrenia-related health costs for hospitalizations and outpatients are greatly reduced. With reference to guidelines published by psychiatric associations around the globe, this article looks at scenarios in Hong Kong on the management of severe mentally ill patients with regard to the use of a host of psychosocial interventions as well as LAI SGAs as a preferable treatment. In particular, it examines the benefits of using LAI SGAs for Hong Kong patients who demonstrated high nonadherence treatment rates due to their social environment. It assesses the rationale behind the early usages of LAI SGAs, which help to provide better recovery outcomes for patients.

Abstract
AIMS There is increasing evidence showing the importance of long-acting injectable antipsychotics in the management of schizophrenia, especially in terms of improving patient medication compliance. A panel of experienced clinicians in Hong Kong mapped out a set of consensus statements with an aim to facilitate the understanding and use of long-acting injectable antipsychotics among local physicians. METHODS Eight discussion areas regarding long-acting injectable antipsychotics were selected by the chairman of the consensus group. A series of meetings were held for the panelists to discuss the published literature and their clinical experience, followed by the drafting of consensus statements. At the final meeting, each consensus statement was voted on anonymously by all members based on its practicability of recommendation in Hong Kong. RESULTS A total of 12 consensus statements on the rational use of long-acting injectable antipsychotics were established and accepted by the consensus group. CONCLUSION The consensus statements aim to provide practical guidance for Hong Kong physicians on the use of long-acting injectable antipsychotics in schizophrenia patients. These statements may also serve as a reference for doctors in other parts of the Asia-Pacific region.

Abstract
BACKGROUND Paliperidone palmitate is a once-monthly injectable, atypical antipsychotic. To our knowledge, there has been only one report of paliperidone palmitate-induced angioedema presenting with acute laryngeal edema with subsequent respiratory arrest. Here, we present a case report of paliperidone palmitate-induced angioedema with a relatively mild clinical presentation compared with the previously reported case, and the patient’s condition was not complicated by life-threatening anaphylaxis.
CASE SUMMARY A 79-year-old female, who had a major neurocognitive disorder due to Alzheimer’s disease with behavioral disturbances. Paliperidone palmitate was off-label used to control her aggression, irritability, and psychosis. After induction doses (150 mg and 100 mg intramuscularly, given 1 wk apart), she developed intermittent swelling of the face, eyelids, and lips on day 17 after the initial dose, and the edema was explicitly seen on day 20. The diagnosis was paliperidone palmitate-induced angioedema. The monthly injection dose was discontinued on day 33 after the initial dose. The angioedema was subsequently alleviated, and it had completely resolved by day 40 after the initial dose.
CONCLUSION Paliperidone palmitate-induced angioedema is a rare condition and can present with a mild, intermittent facial edema, which may be overlooked in clinical practice.

Abstract
Antipsychotics are the mainstay in schizophrenia management, and long-acting injectable (LAI) antipsychotics contribute to the successful maintenance of treatment by improving non-adherence and preventing relapses. Paliperidone palmitate 3-monthly (PP3M) formulation is the only available LAI antipsychotic that offers an extended 3-month window of stable plasma drug concentration, enabling only four injections per year. This paper summarizes clinically relevant endpoints from available evidence for PP3M to bridge translational research gaps and provide measurable outcomes that can be interpreted in clinical practice. Low number-needed-to-treat (NNT) for relapse prevention (NNT [95% CI] 6-month estimate: 4.8 [3.2; 10.0]; 12-month estimate: 3.4 [2.2; 7.0]), and high number-needed-to-harm (NNH [95% CI] akathisia, 27.1 [12.3; -667.1]; tremor, 80.0 [22.5; 67.3]; dyskinesia, -132.6 [44.5; -23.2]; parkinsonism, 160.0 [28.9; -49.8]) quantify the relative benefits and low propensity for adverse events with PP3M. Symptom remission and reductions in positive and negative symptoms indicate treatment stability. Additionally, meaningful functional remission, reduced dosing frequency, and freedom from daily negotiations favorably impact patient preference and attenuate burdensome aspects of caregiving, representing important healthcare determinants that enhance prospects of treatment continuity in schizophrenia. This information can potentially improve clinicians' judgment of treatment choices, clinical response, and patient selection in routine care. Taken together, PP3M is a valuable antipsychotic treatment option, meriting consideration for a broader role in the long-term management of schizophrenia; its utility should not be limited to patients with poor adherence or when oral antipsychotics have failed.

Abstract
PALMFlexS, a prospective multicentre, open-label, 6-month, phase IIIb interventional study, explored tolerability, safety and treatment response in adults (n = 231) with non-acute but symptomatic schizophrenia switching to flexibly dosed paliperidone palmitate (PP) after unsuccessful treatment with risperidone long-acting injectable therapy (RLAT) or conventional depot antipsychotics (APs). Treatment response was measured by change in Positive and Negative Syndrome Scale (PANSS) total score from baseline (BL) to last-observation-carried-forward (LOCF) endpoint (EP). Safety and tolerability assessments included Extrapyramidal Symptom Rating Scale (ESRS) total score and treatment-emergent adverse events. Significant reductions in mean PANSS total score were observed for all groups (-7.5 to -10.6; p ⩽ 0.01 [BL to LOCF EP]). After switching to PP, more than 50% of all patients achieved ⩾20% and one-third of RLAT-treated patients even achieved ⩾50% improvement in PANSS total score. Across groups, there were significant improvements (p < 0.05) in symptom severity as measured by Clinical Global Impression-Severity (CGI-S; trend for improvement with RLAT; p = 0.0568), subjective well-being, medication satisfaction, and patient functioning with PP. PP was generally well tolerated. Clinically relevant benefits were observed in non-acute patients with schizophrenia switched from RLAT or conventional depot APs to PP.

Abstract
OBJECTIVE Schizophrenia in general is notoriously associated with relapses rendering the illness progressive to worse outcomes, a concept of which is compatible with neurotoxicity. Therefore, relapse prevention is of utmost clinical relevance. METHODS In this review, we aim to put relapse into clinical context in the realm of natural history of, or heterogeneity in, schizophrenia and summarize risk factors of relapse. We discuss how to effectively 'define' relapse in schizophrenia and recent meta-analytic studies on this topic to highlight the importance of continuous antipsychotic treatment. RESULTS The following issues emerged: 'How low maintenance antipsychotic dosage could be?’, 'How extended dosing could be?’, 'Who could be successfully withdrawn from antipsychotics?’ and 'How relapse could be defined in the first place?’ The question in particular is how better to deliver antipsychotics at the lowest possible, whereby dose and dosing interval are relevant. While ongoing antipsychotic treatment is the rule, recent works are pointing to a possibility of lower dosage in the maintenance phase of the illness. CONCLUSIONS Bearing in mind that suboptimal adherence and withdrawal from antipsychotics are an established and unequivocal risk factor for relapse, further investigations are certainly needed to explore user-friendly manner of psychopharmacotherapy to prevent relapse in schizophrenia.

Ogino S, Miyamoto S, Miyake N, Yamaguchi N. Benefits and limits of anticholinergic use in schizophrenia: focusing on its effect on cognitive function. Psychiatry Clin Neurosci 2014; 68:37-49. [PMID: 24102938 DOI: 10.1111/pcn.12088] [Citation(s) in RCA: 60] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2013] [Revised: 04/25/2013] [Accepted: 05/26/2013] [Indexed: 12/17/2022]
Abstract
All currently available antipsychotic drugs are the dopamine D2 receptor antagonists and are capable of producing extrapyramidal side-effects (EPS). Anticholinergic drugs are primarily used to treat EPS or prevent EPS induced by antipsychotics in the treatment of psychosis and schizophrenia. However, they can cause a variety of distressing peripheral side-effects (e.g. dry mouth, urinary disturbances, and constipation) and central adverse effects (e.g. cognitive impairment, worsening of tardive dyskinesia, and delirium). Disturbances in cognitive abilities are cardinal features of schizophrenia from its earliest phases and account for much of the functional disability associated with the illness. It is likely that long-term concomitant administration of anticholinergics exacerbates the underlying cognitive impairment in patients with schizophrenia and subsequently affects patients' quality of life. Thus, current treatment guidelines for schizophrenia generally do not recommend the prophylactic and long-term use of anticholinergics. However, the high use of long-term anticholinergic drugs with antipsychotics has been identified as an important issue in the treatment of schizophrenia in several countries. To assess the benefits and limits of anticholinergic use in psychosis and schizophrenia, this article will provide a brief review of the pharmacology and clinical profiles of anticholinergic drugs and will focus on their effects on cognitive function in schizophrenia, particularly during the course of the early phase of the illness. In addition, we will address the effects of discontinuation of anticholinergics on cognitive function in patients with schizophrenia and provide a strategy for adjunctive anticholinergic use in patients treated with long-acting injectable antipsychotics.

Abstract
Commonly used statistical measures to quantify the likelihood of an adverse drug event (ADE) from clinical trials include risk ratio; odds ratio; and number needed to harm (NNH), the reciprocal of absolute risk. This critical review focused on NNH, specifically on its limitations in controlled trials with psychotropic medication. Data for this evaluation were obtained primarily from articles in MEDLINE from 1988 to 2012. Limitations of NNH were found to include the following: a) arbitrary binary cutoffs for continuous measures, b) limited use of confidence intervals, c) limited adjustments for potential baseline confounders, d) limited adjustments for differences in dose and treatment duration, e) rare consideration of high attrition rates, f) variable use of the term harm, g) oversimplified single harm comparisons, h) frequent biased design and reporting, i) undue emphasis on less severe ADEs, j) application primarily to short-term clinical trials, and k) little or no generalizability in community practice. In sum, the NNH metric supplies very limited information on the risks of psychotropic medication. Postmarketing surveillance of community treatment populations using case-control methodology provides far more useful data on serious ADEs.

Abstract
Risperidone long-acting injection (RLAI) was the first second-generation antipsychotic available as a long-acting injection. Paliperidone (9-hydroxyrisperidone) is the active metabolite of risperidone, introduced initially as an extended release oral (ORal Osmotic System, OROS®, Alza Corporation) formulation (Invega®, Janssen). Paliperidone long-acting injection (PLAI) has now been developed as a suspension of paliperidone palmitate nanocrystals in an aqueous formulation (Invega Sustenna®, Xeplion®), administered monthly by intramuscular injection (deltoid or gluteal). Doses of PLAI can be expressed either in milligram equivalents (mg eq) of paliperidone palmitate or in milligrams of the active fraction of paliperidone. The recommended initiation regimen of 150 mg eq (234 mg) on day 1 and 100 mg eq (156 mg) on day 8 (both administered in the deltoid) achieves therapeutic blood levels rapidly and without the necessity of oral supplementation. No refrigeration or reconstitution prior to administration is required. PLAI has been shown in to be effective in controlling the acute symptoms of schizophrenia as well as delaying time to relapse. Safety and tolerability are comparable to RLAI with no new safety signals. Thus, PLAI may represent the rational development of RLAI with greater ease of use.

Abstract
BACKGROUND The purpose of this study was to compare incidence rates and time course of extrapyramidal symptom (EPS)-related treatment-emergent adverse events (TEAEs) between oral and long-acting injectable (LAI) paliperidone. METHODS The analysis included pooled data (safety analysis set, 2,256 antipsychotic-treated and 865 placebo-treated patients with schizophrenia) from seven randomized, double-blind, placebo-controlled paliperidone studies (three oral [6 weeks each] and four LAI [9-13 weeks]) and assessed comparable doses (oral, 3-15 mg; LAI, 25-150 mg eq. [US doses 39-234 mg]). We summarized incidence rates and time of onset for EPS-related TEAE, categorized by EPS group terms, ie, tremor, dystonia, hyperkinesia, parkinsonism, and dyskinesia, and use of anti-EPS medication. Mean scores over time for the Abnormal Involuntary Movement Scale (AIMS, for dyskinesia), Barnes Akathisia Rating Scale (BARS, for akathisia), and Simpson Angus Rating Scale (SAS, for parkinsonism) were graphed. RESULTS Incidence rates for all categories of spontaneously reported EPS-related TEAEs except for hyperkinesia, were numerically lower in pooled LAI studies than in pooled oral studies. Highest rates were observed in the first week of paliperidone-LAI (for all EPS symptoms except dyskinesia) and oral paliperidone treatment (except parkinsonism and tremor). Anti-EPS medication use was significantly lower in LAI (12%) versus oral studies (17%, P = 0.0035). Mean values for EPS scale scores were similar between LAI and oral treatment at endpoint, and no dose response was evident. Mean reductions (standard deviation) from baseline to endpoint in EPS scale scores were larger for LAI (AIMS, -0.10 [1.27]; BARS, -0.09 [1.06]; SAS, -0.04 [0.20]) versus oral studies (AIMS, -0.08 [1.32]; BARS, -0.03 [1.24]; SAS, 0.0 [0.23]). These changes favored LAI for BARS (P = 0.023) and SAS (P < 0.0001), but not for AIMS (P = 0.49), at endpoint for the studies. CONCLUSION In this posthoc descriptive analysis, incidence rates of spontaneously reported EPS-related TEAEs were numerically lower following approximately 90 days of exposure with LAI and approximately 40 days with oral paliperidone at comparable doses.

Abstract
BACKGROUND Paliperidone palmitate, a long-acting, intramuscular formulation of paliperidone, is now available for clinical use. Paliperidone is an active metabolite of risperidone and it is also available in an oral formulation for daily use. OBJECTIVES To compare the effects of paliperidone palmitate with any other treatment for people with schizophrenia and schizophrenia-like illnesses. SEARCH METHODS We searched the Cochrane Schizophrenia Group's Register (November 2009) and inspected references of identified studies for further trials. We contacted the manufacturers of paliperidone palmitate, the Food and Drug Administration, and authors of relevant trials for additional material. SELECTION CRITERIA We included randomised controlled trials (RCTs). DATA COLLECTION AND ANALYSIS We independently selected and critically appraised studies, extracted data and analysed on an intention-to-treat basis. Where possible and appropriate, we calculated risk ratios (RR) and their 95% confidence intervals (CI) with the number needed to benefit/harm statistic (NNB/H). We calculated mean differences (MD) for continuous data. MAIN RESULTS Five studies with 2215 participants compared paliperidone palmitate with placebo. Fewer people left studies early if they were randomised to paliperidone palmitate (n = 2183, 5 RCTs, RR 0.76 CI 0.70 to 0.84, NNTB 9 CI 7 to 14) and those receiving any dose of paliperidone palmitate were significantly less likely to show no improvement in global state (n = 1696, 4 RCTs, RR 0.79 CI 0.74 to 0.85, NNTB 7 CI 5 to 9). People randomised to paliperidone palmitate were less likely to experience a recurrence of psychosis (n = 312, 1 RCT, RR 0.28 CI 0.17 to 0.48, NNTB 5 CI 4 to 6) than those allocated to placebo in a single trial specifically designed to study recurrence. In the other studies where recurrence was recorded only as an adverse event, we found that people who received paliperidone palmitate were also less likely to experience a recurrence of psychotic symptoms (n = 1837, 4 RCTs, RR 0.55 CI 0.44 to 0.68, NNTB 10 CI 8 to 14). Paliperidone palmitate was associated with fewer reports of agitation or aggression (n = 2180, 5 RCTs, RR 0.65 CI 0.46 to 0.91, NNTB 39 CI 25 to 150) and of using anxiolytic medications (n = 2170, 5 RCTs, RR 0.89 CI 0.83 to 0.96, NNTB 16 CI 11 to 44). A consistent, significant elevation in serum prolactin (ng/mL) was found for both men and women receiving paliperidone palmitate, but the data were too heterogenous to sum. We found no evidence of sexual dysfunction in these short-term trials. People receiving paliperidone palmitate had a significantly greater increase in weight (n = 2052, 5 RCTs, MD 1.34 CI 0.97 to 1.70) in comparison with people who received placebo.Two studies with 1969 participants compared flexibly-dosed paliperidone palmitate with flexibly-dosed risperidone long-acting injection. The mean doses of paliperidone palmitate in these trials were 73.3 and 104.6 mg every four weeks compared with risperidone long-acting injection at mean doses, respectively, of 35.3 and 31.7 mg every two weeks. We found no differences between paliperidone palmitate and risperidone long-acting injection for leaving these studies early for any reason (n = 1969, 2 RCTs, RR 1.12 CI 1.00 to 1.25). Those receiving paliperidone palmitate were statistically no more likely to have a recurrence of psychotic symptoms than those receiving risperidone long-acting injection (n = 1961, 2 RCTs, RR 1.23 CI 0.98 to 1.53). While we found no significant difference in the occurrences of deaths in the pooled trials (n = 1967, 2 RCTs, RR 3.62 CI 0.60 to 21.89), we note that a total of six deaths occurred in these two trials, with five deaths among people who received paliperidone palmitate and one death among people who received risperidone long-acting injection. Although death is the most serious of adverse events, the small number of these events in these trials makes it unclear if this finding is meaningful. We found that participants randomised to paliperidone palmitate were significantly less likely to use anticholinergic medications in these trials (n = 1587, 2 RCTs, RR 0.67 CI 0.55 to 0.82, NNTB 13 CI 10 to 24). We found no data regarding paliperidone palmitate relating to services use, quality of life, behaviour, patient satisfaction, cognitive functioning or cost. AUTHORS' CONCLUSIONS In short-term studies, paliperidone palmitate is an antipsychotic drug that is more efficacious than placebo. We found its adverse effects to be similar to those of its related compounds, paliperidone and risperidone, with extrapyramidal movement disorders, weight gain, and tachycardia all more common with paliperidone palmitate than placebo. While no difference was found in the incidence of reported adverse sexual outcomes, paliperidone palmitate is associated with substantial increases in serum prolactin. When flexibly dosed with a mean doses of approximately 70 to 110 mg every four weeks, paliperidone palmitate appears comparable in efficacy and tolerability to risperidone long-acting injection flexibly dosed with mean doses of approximately 35 mg every two weeks.

Abstract
Clinical practice benefits from research to inform good decision making. Evidence-based medicine (EBM) helps physicians integrate experience and individual expertise with the best evidence. Various philosophical concepts, including "primum non nocere," are balanced to achieve this. The tools of EBM, such as number needed to treat, are easy to calculate and to use. Other valuable tools include number needed to harm, attributable risk, and likelihood of being helped or harmed. It is also important to distinguish between relative risk and absolute risk to avoid drawing the wrong conclusions. With the right teaching techniques to grab attention and encourage active participation, real examples can be used to impart practical skills that the clinician can employ in translating research findings into something that helps the individual patient.

Abstract
OBJECTIVE Paliperidone palmitate is an atypical long-acting injectable (LAI) antipsychotic that has been approved for use in the US, EU, Australia and numerous other countries for acute and maintenance therapy of schizophrenia. LAI antipsychotics are often viewed as a 'last-resort' treatment for difficult-to-treat patients, however this article considers their role more broadly in the management of partial or non-adherence in schizophrenia. METHOD A search of MedLine, CTR and PsychInfo was conducted to identify relevant publications and clinical trials (search term 'paliperidone palmitate', up to December 2010). The findings were discussed in a number of teleconferences and the manuscript was finalized with a face-to-face meeting of the authors group. MAIN FINDINGS Relapse prevention in schizophrenia requires a comprehensive approach to treatment, which includes antipsychotic medication and psychosocial measures as well as family and/or carer involvement. Good symptom control and the interconnected issue of treatment adherence are arguably the most crucial factors for success. Carer and patient feedback should be carefully considered. Negotiation about commencing LAI therapy done early in course of disease is easier than many clinicians believe, although it is not often attempted in practice. Paliperidone palmitate is useful in both the acute and maintenance phases of treatment. COMMENTARY A case-based approach is presented to suggest various opportunities where use of paliperidone palmitate could be considered within the disease course of schizophrenia. CONCLUSIONS Paliperidone palmitate offers some advantages in terms of tolerability, simplicity of treatment initiation and long duration between injections. The consensus of the authors is that rather than reserving paliperidone palmitate for use in difficult-to-treat or refractory patients, it could be used to promote adherence and prevent relapse earlier in the course of the illness.
