    The Prescribing Pattern of a New Antipsychotic: A Descriptive Study of Aripiprazole for Psychiatric In-Patients,

    BASIC AND CLINICAL PHARMACOLOGY & TOXICOLOGY, Issue 1 2008
    Stig Ejdrup Andersen
    The objective of this descriptive study is to examine the day-to-day prescriptions of aripiprazole to an unselected population of psychiatric in-patients. From 1 February to 1 May 2006, present and former in-patients treated with aripiprazole were identified. Prescriptions of aripiprazole and psychoactive comedication were collected retrospectively from the patient records. Seventy-one patients, mainly schizophrenic, received aripiprazole 2.5 to 55 mg/day for median 350 days. The median average exposure was 18.9 mg/day (range 2.5,45 mg/day) and exceeded 15 and 30 mg/day in 63% and 4.2% of the patients, respectively. Generally, aripiprazole was either added to the existing antipsychotic treatment or replaced other antipsychotics; only 17% of the patients were treatment-naïve. In 25% aripiprazole, monotherapy was commenced whereas aripiprazole-antipsychotic combinations were initially prescribed in 75%. Overall, 85% of the patients received periods of antipsychotic polypharmacy and aripiprazole was combined with 17 different antipsychotics. Each patient received median three (range 0,8) psychoactive drugs parallel with aripiprazole. This study demonstrates reality in psychopharmacology and quote aripiprazole as example. In day-to-day practice, aripiprazole is used as part of highly individualized regimens comprising polypharmacy and excessive dosing. Although theoretically appropriate for some patients, this approach also implies conducting unblinded and uncontrolled mini-experiments. Sparse evidence supports this practice and effectiveness studies of aripiprazole that takes into account the true complexity of clinical prescribing are urgently needed. [source]


    Antipsychotic and mood stabilizer efficacy and tolerability in pediatric and adult patients with bipolar I mania: a comparative analysis of acute, randomized, placebo-controlled trials

    Correll CU, Sheridan EM, DelBello MP. Antipsychotic and mood stabilizer efficacy and tolerability in pediatric and adult patients with bipolar I mania: a comparative analysis of acute, randomized, placebo-controlled trials. Bipolar Disord 2010: 12: 116,141. © 2010 The Authors. Journal compilation © 2010 John Wiley & Sons A/S. Objective:, To compare antipsychotic and mood stabilizer (MS) efficacy and tolerability in youth and adults with bipolar mania. Methods:, Medline/PubMed search for studies including: (i) youth (< 18 years) or adults (, 18 years); (ii) bipolar I disorder; (iii) double-blind, randomized, placebo-controlled trial (DB-RPCT); (iv) , 12 weeks of treatment; and (v) calculable effect sizes (ES) and/or numbers needed to treat/harm (NNT/NNH) ± 95% confidence intervals (CI). Non-overlapping 95% CIs determined significant group differences. Results:, We identified nine DB-RPCTs in youth (n = 1,609), 5 evaluating second-generation antipsychotics (SGAs) (n = 1,140) and 4 evaluating MSs (n = 469). We also identified 23 DB-RPCTs in adults (n = 6,501), 14 including SGAs (n = 3,297), 5 using haloperidol as an active comparator (n = 580), and 11 including MSs (n = 2,581). Young Mania Rating Scale scores improved significantly more with SGAs than MSs in youth (ES = 0.65, CI: 0.53,0.78 versus 0.24, CI: 0.06,0.41) and adults (ES = 0.48, CI: 0.41,0.55 versus 0.24, CI: 0.17,0.31). After excluding topiramate studies, SGAs had larger ES than MSs only in youth (ES = 0.65, CI: 0.53,0.78 versus 0.20, CI: 0.02,0.39), but not adults (ES = 0.48, CI: 0.41,0.55 versus 0.46, CI: 0.37,0.55). However, in adults SGAs had significantly larger ES regarding Clinical Global Impressions scores than MSs, even without topiramate (ES = 0.75, CI: 0.68,0.82 versus 0.24, CI: 0.07,0.41). Rates of response, remission, and discontinuation due to any reason compared to placebo were similar between medication and age groups, except for more favorable NNTs for remission with SGAs than MSs in adults after excluding topiramate. SGAs caused more weight gain than MSs in youth (ES = 0.53, CI: 0.41,0.66 versus 0.10, CI: ,0.12,0.33), but not in adults (ES = 0.13, CI: 0.05,0.22 versus 0.00, CI: ,0.08,0.08). However, results were heterogeneous and not significant in either age group after excluding topiramate. Nevertheless, SGA-related weight gain was significantly greater in youth than adults. In youth, SGA-related somnolence was greater than with MSs (NNH = 4.7, CI: 3.9,6.0 versus 9.5, CI: 6.3,23.5), and more likely than in adults (NNH = 7.1, CI: 6.1,8.8). Conversely, youth experienced less akathisia with SGAs than adults (NNH = 20.4, CI: 14.1,36.5 versus 10.2, CI: 8.1,13.7), likely due to lower doses/slower titration. Conclusions:, In treating mania, potentially greater short-term efficacy compared to placebo with SGAs versus MS needs to be balanced against increased adverse events, especially in youth. [source]

    Baandrup L, Allerup P, Lublin H, Nordentoft M, Peacock L, Glenthoj B. Evaluation of a multifaceted intervention to limit excessive antipsychotic co-prescribing in schizophrenia out-patients. Objective:, To evaluate the effect of a multifaceted educational intervention on the frequency of antipsychotic co-prescribing in adult schizophrenia out-patients. Method:, Controlled quasi-experimental study performed in two Danish municipalities matched for baseline prevalence of antipsychotic polypharmacy, socioeconomic status and functional level of patients. The intervention was aimed at psychiatric healthcare providers and consisted of 1 day of didactic lectures, six 3-h educational outreach visits and an electronic reminder during drug prescribing. Results:, Between-group use of antipsychotic polypharmacy was compared at baseline (intervention group, N = 232/control group, N = 351) and after 1 year of intervention (intervention group, N = 216/control group, N = 386). The prevalence of antipsychotic polypharmacy at follow-up was not significantly different between treatment settings when adjusting for differences in case-mix (P = 0.07). Conclusion:, This multifaceted educational intervention failed to reduce the frequency of antipsychotic co-prescribing, but it suggested that future efforts to improve prescribing practice should address organizational barriers to implementation.

    Wijkstra J, Burger H, van den Broek WW, Birkenhäger TK, Janzing JGE, Boks MPM, Bruijn JA, van der Loos MLM, Breteler LMT, Ramaekers GMGI, Verkes RJ, Nolen WA. Treatment of unipolar psychotic depression: a randomized, double-blind study comparing imipramine, venlafaxine, and venlafaxine plus quetiapine. Objective:, It remains unclear whether unipolar psychotic depression should be treated with an antidepressant and an antipsychotic or with an antidepressant alone. Method:, In a multi-center RCT, 122 patients (18,65 years) with DSM-IV-TR psychotic major depression and HAM-D-17 , 18 were randomized to 7 weeks imipramine (plasma-levels 200,300 ,g/l), venlafaxine (375 mg/day) or venlafaxine,quetiapine (375 mg/day, 600 mg/day). Primary outcome was response on HAM-D-17. Secondary outcomes were response on CGI and remission (HAM-D-17). Results:, Venlafaxine,quetiapine was more effective than venlafaxine with no significant differences between venlafaxine,quetiapine and imipramine, or between imipramine and venlafaxine. Secondary outcomes followed the same pattern. Conclusion:, That unipolar psychotic depression should be treated with a combination of an antidepressant and an antipsychotic and not with an antidepressant alone, can be considered evidence based with regard to venlafaxine,quetiapine vs. venlafaxine monotherapy. Whether this is also the case for imipramine monotherapy is likely, but cannot be concluded from the data. [source]


    Antipsychotic prescribing trends: a review of pharmaco-epidemiological studies

    ACTA PSYCHIATRICA SCANDINAVICA, Issue 1 2010
    H. Verdoux
    Objective:, To review findings from pharmaco-epidemiological studies exploring antipsychotic (AP) drugs prescribing trends. Method:, We retrieved original studies that explored AP prescribing trends in general population samples since 2000. For each study, we extracted information on sampling method, period, assessment of AP use and corresponding estimates (incidence rates, prevalence rates, pharmacy sales, prescription data) and diagnostic assessment. Results:, Nearly all studies meeting the inclusion criteria (n = 17) showed an increase in AP prescriptions, mainly because of a dramatic rise in second-generation antipsychotics (SGAP) prescriptions. APs are often prescribed for non-psychotic disorders in adults as well as in children and adolescents. Conclusion:, Considering the growing number of persons from the general population exposed to APs, population studies assessing the risk/benefit ratio of SGAP use in disorders other than psychosis are necessary, particularly in children and adolescents.

    Applied psychometrics in clinical psychiatry: the pharmacopsychometric triangle

    ACTA PSYCHIATRICA SCANDINAVICA, Issue 5 2009
    P. Bech
    Objective:, To consider applied psychometrics in psychiatry as a discipline focusing on pharmacopsychology rather than psychopharmacology as illustrated by the pharmacopsychometric triangle. Method:, The pharmacopsychological dimensions of clinically valid effects of drugs (antianxiety, antidepressive, antimanic, and antipsychotic), of clinically unwanted effects of these drugs, and the patients' own subjective perception of the balance between wanted and unwanted effects are analysed using rating scales assessed by modern psychometric tests (item response theory models) Results:, Symptom rating scales fulfilling the item response theory models have been shown to be psychometrically valid outcome scales as their total scores are sufficient statistics for demonstrating dose,response relationship within the various classes of antianxiety, antidepressive, antimanic or antipsychotic drugs. The total scores of side-effect rating scales are, however, not sufficient statistics, implying that each symptom has to be analysed individually. Self-rating scales with very few items appear to be sufficient statistics when measuring the patients' own perception of quality of life. Conclusion:, Applied psychometrics in psychiatry have been found to cover a pharmacopsychometric triangle illustrating the measurements of wanted and unwanted effects of pharmacotherapeutic drugs as well as health-related quality of life.

    Augmentation of clozapine with a second antipsychotic , a meta-analysis of randomized, placebo-controlled studies

    ACTA PSYCHIATRICA SCANDINAVICA, Issue 6 2009
    D. M. Taylor
    Objective:, Inadequate response to clozapine treatment is frequently encountered in practice and augmentation strategies have been developed in an attempt to improve response. Aims of the study were to evaluate the therapeutic effect of adding an antipsychotic drug to clozapine treatment. Method:, Meta-analysis of randomized, placebo-controlled studies of antipsychotic augmentation of clozapine treatment. Results:, Ten studies (including 522 subjects) met inclusion criteria. Antipsychotic augmentation showed significant benefit over the addition of placebo on only one outcome measure examined [mean effect size for rating scale score (BPRS/PANSS) ,0.180, 95% CI ,0.356 to ,0.004]. Antipsychotic augmentation showed no advantage on withdrawals from trials (risk ratio 1.261, 95% CI 0.679,2.345) or on CGI scores (effect size ,0.661, 95% CI ,1.475 to 0.151). Duration of study was not associated with outcome (P = 0.95). There was no evidence of publication bias. Conclusion:, In studies lasting up to 16 weeks, the addition of an antipsychotic to clozapine treatment has marginal therapeutic benefit. Longer and larger trials are necessary to demonstrate the precise therapeutic utility of antipsychotic co-therapy with clozapine. [source]


    Acculturation is associated with the prevalence of tardive dyskinesia and akathisia in community-treated patients with schizophrenia

    ACTA PSYCHIATRICA SCANDINAVICA, Issue 6 2008
    S. Sundram
    Objective:, Ethnicity is a risk factor for tardive dyskinesia (TD) and other antipsychotic drug-induced movement disorders (ADIMD). It is unclear whether this association is mediated through genetic, environmental or cultural factors individually or in combination. This pilot study aimed to explore this interaction by determining if acculturation in migrant groups contributed to the prevalence of ADIMD. Method:, Culturally diverse but relatively genetically homogeneous (white Caucasian) patients with schizophrenia (n = 40) treated at a single site were assessed for the presence of ADIMD and level of acculturation. Results:, Higher levels of acculturation correlated with an increased prevalence of TD and akathisia but not Parkinsonism. The level of acculturation significantly predicted TD. Conclusion:, This study identifies for the first time that acculturation significantly contributes to the prevalence of TD and akathisia but not Parkinsonism in culturally diverse migrant populations and must be accounted for when explaining ethnic variation in rates of ADIMD.

    The case for long-acting antipsychotic agents in the post-CATIE era

    ACTA PSYCHIATRICA SCANDINAVICA, Issue 4 2007
    H. A. Nasrallah
    Objective:, Long-acting antipsychotic agents were developed to promote treatment compliance in patients requiring maintenance treatment for schizophrenia. Method:, An analysis of the impact of non-compliance on treatment outcomes in schizophrenia and the advantages and disadvantages of long-acting antipsychotics. Results:, Partial or total non-compliance with oral antipsychotics remains widespread and is associated with significant increases in the risk of relapse, rehospitalization, progressive brain tissue loss and further functional deterioration. Long-acting agents have the potential to address issues of all-cause discontinuation and poor compliance. The development of the first long-acting atypical antipsychotic, which appears to be effective and well tolerated, should further improve the long-term management of schizophrenia. Conclusion:, Long-acting agents represent a valuable tool for the management of schizophrenia and merit wider use, especially in light of emerging literature regarding the neuroprotective advantages of atypical antipsychotics over conventional agents in terms of regenerating brain tissue during maintenance therapy.

    Effectiveness and tolerability of risperidone in Asian patients with first-episode psychosis

    ACTA PSYCHIATRICA SCANDINAVICA, Issue 2002
    S. Verma
    Objectives, To evaluate the effectiveness and tolerability of risperidone in Asian patients with first-episode psychosis and to examine correlates of response in a naturalistic study. Method, Patients with first-episode psychosis were evaluated at baseline and weekly for 6 weeks with the Positive and Negative Scale for Schizophrenia (PANSS), Simpson,Angus Rating Scale (SARS), Barnes Akathisia Rating Scale (BARS), Rating Scale for Side-effects (RSSE), and the Abnormal Involuntary Movement Scale (AIMS). Results, 42 patients with a mean age of 24.85 ± 9.68 years and mean duration of untreated illness of 11.91 ± 22.04 months were recruited. The mean dose of risperidone was 1.82 ± 0.77 mg. The mean reduction in PANSS score was from 67.97 ± 20.02 at baseline to 42.53 ± 14.08 at week 6 (P < 0.005). The incidence of extrapyramidal symptoms was 9.5% and akathisia was 7.1%. 45.2% of patients showed more than or equal 40% reduction in the PANSS score (responders). When responders were compared to nonresponders, the responders had a significantly higher total and positive PANSS score at baseline. Conclusion, Risperidone is an effective and safe antipsychotic in first-episode psychosis. [source]


    Augmentation with sulpiride for a schizophrenic patient partially responsiveto clozapine

    ACTA PSYCHIATRICA SCANDINAVICA, Issue 5 2000
    Jean H. Stubbs
    Objective:,Schizophrenic patients who are only partially responsive to clozapine pose a therapeutic challenge. In these circumstances some clinicians would consider adding in a second antipsychotic. We present a case report and review evidence for the efficacy of such augmentation strategies. Method:,Single case report and literature review. Results:,The total number of patients in studies and case reports of combining clozapine with other antipsychotics is small. There has been only one randomized controlled trial. This found the addition of sulpiride to clozapine resulted in clinical improvement in some patients. Conclusion:,Further randomized controlled studies of augmentation of clozapine therapy are needed to provide scientific justification for this clinical practice. [source]


    Stability of medication in early psychosis: a comparison between second-generation and low-dose first-generation antipsychotics

    EARLY INTERVENTION IN PSYCHIATRY, Issue 1 2009
    Stein Opjordsmoen
    Abstract Aim: This naturalistic study aims to compare discontinuation rates for low-dose first-generation versus second-generation antipsychotics in first-episode psychotic patients. Methods: The prescription of antipsychotic medication in 301 consecutively admitted patients with first-episode psychosis from four catchment areas is described. For the first year of inclusion a first-generation antipsychotic in low dose was recommended as the first medication. From the second year a second-generation antipsychotic was recommended as first choice. Switching was allowed when any drug was judged to be ineffective or to have serious side-effects. Switching during the first 2 years after inclusion is described. Results: Switching from a low-dose first-generation antipsychotic was more frequent than from a second-generation antipsychotic (90.7 vs. 58.4%). Lack of therapeutic effect and side-effects were the more frequently recorded reasons for changing in the first-generation group. Akathisia, parkinsonism, dyskinesias, dystonia and dysphoria were more often reported in patients on first-generation drugs. Weight gain and sedation were more often reported in patients on second-generation drugs. Conclusion: The findings suggest a better adherence to and tolerability for second-generation antipsychotics than for low-dose first-generation antipsychotics in first-episode psychosis. [source]


    Atypical antipsychotics and anorexia nervosa: A review

    EUROPEAN EATING DISORDERS REVIEW, Issue 1 2010
    Rebecca F. McKnight
    Abstract Background There is currently mixed opinion regarding the value of using atypical antipsychotics to treat anorexia nervosa (AN). Aims To evaluate the literature on the use of atypical antipsychotics in AN. Method A review of all studies and clinical guidelines published before September 2009 involving use of an atypical antipsychotic in patients with AN. Analysis is by narrative synthesis. Results Forty-three publications or study protocols were found, including four randomized-controlled trials, five open-label trials and 26 case reports. The most studied drugs were olanzapine, quetiapine and risperidone. Atypical antipsychotics appear safe and there is some evidence of positive effects on depression, anxiety and core eating disordered psychopathology in patients with anorexia nervosa. Currently there is insufficient evidence to confirm atypical antipsychotics enhance weight gain in this setting. Conclusions Further high quality evidence is needed in this area in order to provide practical guidance to clinicians. However, the main challenge is to persuade adequate numbers of AN patients to participate in research trials. Copyright © 2010 John Wiley & Sons, Ltd and Eating Disorders Association. [source]


    Long-term safety and efficacy of long-acting risperidone in elderly psychotic patients

    HUMAN PSYCHOPHARMACOLOGY: CLINICAL AND EXPERIMENTAL, Issue 8 2007
    Werner Kissling
    Abstract This subgroup analysis of the 6-month, open-label Switch to Risperidone Microspheres (StoRMi) trial evaluated long-term safety and efficacy of a direct conversion to risperidone long-acting injectable (RLAI) in 52 elderly patients (,65 years) with psychosis stabilized on oral or depot antipsychotic. Study outcomes included adverse events, movement disorder severity, psychiatric symptoms, functional ability, quality of life and patient satisfaction. Change in the Positive and Negative Syndrome Scale at endpoint was the primary efficacy measure. The most common dosage of RLAI used at endpoint was 25,mg every 14 days (60%). The trial was completed by 81% of patients, with six patients discontinuing treatment due to an adverse event. Tolerability was good and most side effects were mild to moderate. Serious adverse events occurred in 11 patients. Two of these (suicidal attempt, n,=,1; exacerbation of disease, n,=,1) were considered possibly related to RLAI. Conversion to RLAI resulted in significant improvements in movement disorder severity, psychiatric symptoms, functional status and patient satisfaction. Mean PANSS total decreased by 15.8 at endpoint, with 23 patients (46.9%) experiencing a ,20% improvement. This post-hoc analysis supports that RLAI is well tolerated and safe in elderly patients with psychotic illnesses switched from stable antipsychotic regimens, and suggests possible efficacy, although inferences are limited.

    Clinical correlates of clozapine prescription for schizophrenia in China

    HUMAN PSYCHOPHARMACOLOGY: CLINICAL AND EXPERIMENTAL, Issue 1 2007
    Yu-tao Xiang
    Abstract Aims Few studies have investigated the prescription patterns of clozapine in outpatients with schizophrenia in China. It is an important issue due to clozapine's high efficacy and potentially fatal side effect profile. This study examined the use of clozapine and its correlates in China. Methods Three hundred ninety-eight clinically stable outpatients with schizophrenia were randomly selected and interviewed in Hong Kong (HK) and Beijing (BJ). Assessment instruments included the Structured Clinical Interview for DSM-IV, Brief Psychiatric Rating Scale, Simpson and Angus Scale of Extrapyramidal Symptoms, Barnes Akathisia Rating Scale and the Hong Kong and Mainland China World Health Organization Quality of Life Schedule-Brief version. Assessments were performed by the same investigator in both sites. Results Clozapine was prescribed to 15.6% of (n,=,62) patients. There was a wide inter-site variation between HK and BJ. Use of clozapine was associated with age, age at onset, extrapyramidal side effects (EPS), having health insurance, use of depot and typical antipsychotic and anticholinergic drugs and benzodiazepines as well as history of suicidal attempts. On multiple logistic regression analysis, the number of hospitalizations, site (HK vs. BJ), use of typical antipsychotics, polypharmacy and co-prescription with anticholinergics were significantly associated with the prescription of clozapine. No significant differences were found between the clozapine and non-clozapine groups with regard to any of the quality of life domains. Conclusion A combination of economical and clinical factors, health policies and the characteristics of the treatment settings plays important roles in determining clozapine use. Clozapine appears to have little significant influence on quality of life in clinical stable Chinese patients with schizophrenia. Copyright © 2007 John Wiley & Sons, Ltd. [source]


    Efficacy and tolerability of quetiapine in patients with schizophrenia who switched from haloperidol, olanzapine or risperidone

    HUMAN PSYCHOPHARMACOLOGY: CLINICAL AND EXPERIMENTAL, Issue 8 2005
    Ilkka Larmo
    Abstract A post hoc analysis of the SPECTRUM trial was carried out to evaluate whether the improvements in efficacy and tolerability gained on switching to quetiapine occurred consistently for patients previously treated with either: haloperidol (n,=,43); olanzapine (n,=,66); or risperidone (n,=,55) monotherapy. Patients were initiated with quetiapine to 400,mg/day over 7 days, and then flexibly dosed (300,750,mg/day) for 11 weeks. The mean (SD) modal dose of quetiapine was 501 (138),mg/day in the haloperidol subgroup, 472 (147),mg/day in the olanzapine subgroup and 485 (141),mg/day in the risperidone subgroup at the study endpoint. Switching to quetiapine induced significant improvements from baseline in PANSS scores, with least square mean changes in total scores of ,32.5, ,15.4, and ,18.5 for patients previously treated with haloperidol, olanzapine and risperidone, respectively, (all p,<,0.001 vs baseline). Significant improvements were also noted in CDSS scores, particularly for patients clinically depressed at baseline (all p,<,0.001 vs baseline). There were significant reductions in EPS on the SAS and BAS for all subgroups (all p,<,0.001 vs baseline). Switching to quetiapine produced efficacy and tolerability benefits regardless of whether their previous antipsychotic was haloperidol, olanzapine or risperidone.

    Towards consensus in the long-term management of relapse prevention in schizophrenia

    HUMAN PSYCHOPHARMACOLOGY: CLINICAL AND EXPERIMENTAL, Issue 3 2005
    M. Taylor
    Abstract Approach to developing guidance When developing guidance for the long-term management of schizophrenia, one approach is to adopt a proactive strategy that sets out clear treatment goals and strategies. This should involve a broad view being taken, embracing overall mental and physical well-being rather than simply the absence of illness. Although relapse prevention is an important goal of any long-term management strategy, there are other aspects that need to be considered, such as reintegration into society, regaining independence and quality of life. Current treatment To help achieve these goals, a range of interventions can be incorporated into long-term management strategies for schizophrenia, including pharmacological interventions, psychosocial therapies and alliance-building initiatives. The current UK National Institute for Clinical Excellence guidelines already recommend that continuous therapy should be practised using an atypical (second-generation) antipsychotic drug, whenever possible, in preference to older typical drugs. The launch of the first long-acting atypical antipsychotic is an interesting new advance that may benefit many patients with schizophrenia. Psychosocial interventions, particularly family-based therapies, as well as cognitive behavioural and compliance therapies, when used alongside antipsychotics, have been shown to reduce relapse rates dramatically and to assist in social reintegration. In addition, forging collaborative alliances with patients and their carers can help to demystify schizophrenia and empower patients to take responsibility for their illness. Consensus statement This article outlines a consensus reached by a panel of leading UK healthcare professionals working with schizophrenia brought together to discuss long-term management strategies.

    Worldwide-Schizophrenia Outpatient Health Outcomes (W-SOHO): baseline characteristics of pan-regional observational data from more than 17,000 patients,

    INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 11 2009
    J. Karagianis
    Summary Objective:, To describe the Worldwide-Schizophrenia Outpatient Health Outcomes (W-SOHO) patient population at study entry, focusing on illness burden and prescribing practices across regions. Methods:, The SOHO study was a 3-year, prospective, observational study designed to assess costs and outcomes associated with antipsychotic use in outpatients initiating or changing antipsychotic (with an emphasis on olanzapine compared with other antipsychotics). SOHO was conducted in 10 European countries and 27 other countries as Intercontinental SOHO (IC-SOHO). Data from all countries have been pooled to produce the W-SOHO dataset. Main outcomes measures:, Clinical Global Impression-Schizophrenia (CGI-SCH) severity scores, psychotropic medication use, adverse events, social interaction, housing and employment status, self-perceived health state (EuroQoL EQ-5D scale and Visual Analogue Scale, EQ-VAS), and reasons for initiation/change of antipsychotic. Results:, The W-SOHO database comprises 17,384 patients from six regions; East Asia (n = 1223), Central and Eastern Europe (n = 2175), Northern Europe (n = 4291), Southern Europe (n = 5788), Latin America (n = 2566), North Africa and the Middle East (n = 1341). Overall, patients were 38 ± 13 years old (mean ± SD), moderately ill (mean CGI-SCH overall score of 4.4 ± 1.0) with a median duration of illness of 7 years (interquartile range 1,16 years); 43% were female, 10% were receiving antipsychotic medication for the first time. Adverse events were prevalent across all regions; on average, 50% (range 41,59%) of patients taking antipsychotics exhibited extrapyramidal symptoms at baseline, and 62% (34,67%) of patients reported sexual dysfunction in the previous month. On average, only 19% (16,23%) of patients were in paid employment and as many as 69% were living in dependent housing. Conclusions:, Despite inherent diversity in these patients and the health care systems supporting them, there are striking cross-regional similarities in baseline characteristics for most measures. Not all countries are represented; regional comparisons may not be valid outside of the countries studied. [source]


    Iloperidone for schizophrenia: a review of the efficacy and safety profile for this newly commercialised second-generation antipsychotic

    INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 8 2009
    L. Citrome
    Summary Objective:, The aim of the study was to describe the efficacy and safety of iloperidone for the treatment of schizophrenia. Data sources:, The pivotal registration trials were accessed by querying http://www.pubmed.gov, http://www.fda.gov and http://www.clinicaltrials.gov for the search term ,iloperidone'. Study selection:, Four published primary reports of phase III studies were identified as well as preclinical animal and receptor affinity studies that describe potential mechanisms of action and pharmacogenomic studies that identify potential genetic biomarkers for efficacy and tolerability. Product labelling provided additional data. Data extraction:, Descriptions of the principal results and calculation of number needed to treat (NNT) and number needed to harm (NNH) for relevant dichotomous outcomes were extracted from the study reports. Additional safety outcomes subject to NNH analysis were obtained from product labelling. Data synthesis:, Iloperidone is a second-generation antipsychotic agent indicated for the acute treatment of schizophrenia in adults. Iloperidone has been evaluated in several double-blind placebo-controlled clinical trials. The oral formulation has demonstrated efficacy in reducing the symptoms of acute schizophrenia at fixed daily doses ranging from 12 to 24 mg. Data reported for categorical definitions of response using the Positive and Negative Syndrome Scale were limited to one study and specifically to rates of achieving a , 20% decrease in the positive subscale from baseline; significantly more patients receiving iloperidone 24 mg/day (72%) than placebo (52%) met this criterion, yielding a NNT of five. Iloperidone should be titrated slowly to avoid orthostatic hypotension, potentially delaying the achievement of a therapeutic dose level. There appears to be a dose relationship for adverse events such as dizziness, somnolence and dry mouth; for example NNH vs. placebo for somnolence was 25 for iloperidone 10,16 mg/day and 10 for 20,24 mg/day. There is a possibility of a therapeutic dose response as well. Iloperidone is essentially free of extra-pyramidal side effects. Iloperidone is associated with weight gain comparable with risperidone. Long-term double-blind maintenance studies have demonstrated iloperidone's non-inferiority to haloperidol for relapse prevention. Product labelling includes a warning about the potential for QT interval prolongation. At present there are no efficacy studies available that are powered to directly compare iloperidone with other second-generation antipsychotics. The development of a depot formulation of iloperidone as well as efforts to identify genetic biomarkers for prediction of both efficacy and tolerability are in progress. Conclusions:, Aside from paliperidone, iloperidone is the first new second-generation antipsychotic to be commercialised in the USA since 2002. From the limited registration data, iloperidone appears to be relatively well tolerated once titrated to a therapeutic level and can be a useful option to consider. The development of a depot formulation and potential for genetic biomarkers may make this agent compelling. Further comparisons with other available agents among patients with schizophrenia in the ,real world' are needed. [source]

    Abstract Objective To investigate determinants of antipsychotic medication use among older people living in aged care homes in Australia. Design Retrospective study of a random sample of de-identified medication reports using cross-sectional data gathered between 1 January 2008 and 30 June 2008 in Australia. Subjects The mean (SD) age of the residents was 84.0 (9.0) years. Seventy-five per cent were females. Measures Resident demographics, clinical characteristics, medical diagnoses and prescribed medication were systematically recorded. Logistic regression (LR) models were used to determine predictors for any antipsychotic, atypical and conventional antipsychotic use. Results Twenty-three per cent of the residents were prescribed one or more antipsychotics. In the LR model, factors for predicting the odds ratio and 95% confidence interval (CI) for any antipsychotic medication use were agitation (7.11, 95% CI 3.15,16.03), challenging behaviours (7.47, 95% CI 2.53,22.10), dementia (2.35, 95% CI 1.36,4.06), dementia with mood disorder (0.39, 95% CI 0.16,0.92), paranoia (6.70, 95% CI 1.08,41.55), psychosis (14.79, 95% CI 3.64,60.00) and any psychiatric diagnosis (3.30, 95% CI 1.82,6.00). Use of atypical antipsychotic medication was significant for agitation (4.58, 95% CI 2.05,10.23), aggression (2.25, 95% CI 1.05,4.78), challenging behaviours (8.01, 95% CI 2.76,23.24), dementia (3.64, 95% CI 1.99,6.67), dementia with mood disorder (0.16, 95% CI 0.06,0.43), psychosis (16.51, 95% CI 4.28,63.66) and any psychiatric diagnosis (4.44, 95% CI 2.33,8.46). Conclusions Psychiatric diagnosis, psychosis and dementia were associated with significantly greater odds for the use of antipsychotic medications. Older people suffering from dementia and comorbid mood disorders treated with antidepressants were less likely to be prescribed atypical antipsychotics. Copyright © 2009 John Wiley & Sons, Ltd.

    Quetiapine indication shift in the elderly: diagnosis and dosage in 208 psychogeriatric patients from 2000 to 2006

    INTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 5 2007
    Lorenz Hilwerling
    Abstract Rationale Quetiapine was approved in Germany as an atypical antipsychotic for treatment of schizophrenia in 2000, followed by the approval as an antipsychotic for treatment of bipolar mania in 2003. The approval of quetiapine for treatment of bipolar depression is expected. We hypothesized that the psychogeriatric prescription pattern for quetiapine shifts from the psychotic to the affective spectrum. Methods Retrospectively we screened discharge reports of all geriatric inpatients of the psychiatric department of the Ruhr-University of Bochum in the period from January 2001 until March 2006 and identified 208 individual patients aged over 60 years, who had received quetiapine as final medication. Age, gender, daily drug dose, year of treatment and diagnosis (according to ICD-10) were recorded and analyzed. Results Over the six-year time span, the proportion of affective disorders (F3) as indication for quetiapine in the elderly increased, whereas the proportion of dementia (F0) as indication for quetiapine decreased significantly. The proportion of schizophrenic disorders (F2) treated with quetiapine did not change significantly. Discussion Since the decision of the German Federal Court in 2002 ,off label' use goes to the expenses of the prescriber. So the decrease of quetiapine in dementia is probably due to its ,off label' status in dementia. The psychogeriatric indication shift for quetiapine towards affective disorders could be the consequence of good clinical experiences with the drug and growing evidence for its antidepressant effect. Conclusion In addition to controlled pharmacological trials prospective clinical research is needed to evaluate the prescription attitudes of clinicians. Copyright © 2006 John Wiley & Sons, Ltd.

    Are All Commonly Prescribed Antipsychotics Associated with Greater Mortality in Elderly Male Veterans with Dementia?

    JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 6 2010
    Rebecca C. Rossom MD
    OBJECTIVES: To estimate mortality risk associated with individual commonly prescribed antipsychotics. DESIGN: Five-year retrospective study. SETTING: Veterans national healthcare data. PARTICIPANTS: Predominantly male, aged 65 and older, with a diagnosis of dementia and no other indication for an antipsychotic. Subjects who received an antipsychotic were compared with randomly selected controls who did not. Exposed and control cohorts were matched according to their date of dementia diagnosis and time elapsed from diagnosis to the start of antipsychotic therapy. MEASUREMENTS: Mortality during incident antipsychotic use. RESULTS: Cohorts who were exposed to haloperidol (n=2,217), olanzapine (n=3,384), quetiapine (n=4,277), or risperidone (n=8,249) had more comorbidities than their control cohorts. During the first 30 days, there was a significant increase in mortality in subgroups prescribed a daily dose of haloperidol greater than 1 mg (hazard ratio (HR)=3.2, 95% confidence interval (CI)=2.2,4.5, P<.001), olanzapine greater than 2.5 mg (HR=1.5, 95% CI=1.1,2.0, P=.01), or risperidone greater than 1 mg (HR=1.6, 95% CI=1.1,2.2, P=.01) adjusted for demographic characteristics, comorbidities, and medication history using Cox regression analyses. Greater mortality was not seen when a daily dose of quetiapine greater than 50 mg (HR=1.2, 95% CI=0.7,1.8, P=.50) was prescribed, and there was no greater mortality associated with a dose less than 50 mg (HR=0.7, 95% CI=0.5,1.0, P=.03). No antipsychotic was associated with greater mortality after the first 30 days. CONCLUSION: Commonly prescribed doses of haloperidol, olanzapine, and risperidone, but not quetiapine, were associated with a short-term increase in mortality. Further investigations are warranted to identify patient characteristics and antipsychotic dosage regimens that are not associated with a greater risk of mortality in elderly patients with dementia.

    A best-evidence synthesis review of the administration of psychotropic pro re nata (PRN) medication in in-patient mental health settings

    JOURNAL OF CLINICAL NURSING, Issue 9 2008
    John A Baker BNurs, MPhil
    Aims and objectives., This paper aims to synthesise published literature of drug use/administration studies of pro re nata psychotropic medications in mental health wards. Design., The study employed a best-evidence synthesis review design. Background., The administration of psychotropic pro re nata medications is a frequently used clinical intervention in mental health wards. Pro re nata contributes to exposing patients to high doses of antipsychotic medication. Despite the frequent use of pro re nata, there is limited evidence of their effectiveness. Methods., A best-evidence synthesis review. Results., Six major themes emerged from the literature: (i) frequency of administration; (ii) administration during the 24-hour day; (iii) administration associated with length and stage of admission; (iv) rationales for administration; (v) medicines administered (including route of administration); and (vi) effects and side effects of the medicines administered. Conclusions., Overall findings indicate that the administration of psychotropic pro re nata varies radically and appears to be influenced by many variables. Relevance to clinical practice., Patients are most likely to receive a benzodiazepine or typical antipsychotic as pro re nata. Pro re nata is an important and under-researched clinical intervention used in mental health wards. [source]

    Abstract. Vestergaard P, Olsen ML, Paaske Johnsen S, Rejnmark L, Toft Sørensen H, Mosekilde L (Aarhus University Hospital, Denmark; and Aarhus and Aalborg University Hospitals; Aarhus, Denmark). Corticosteroid use and risk of hip fracture: a population-based case,control study in Denmark. J Intern Med 2003; 254: 486,493. Background. Corticosteroids (CS) are used in a wide range of conditions but have several possible adverse effects including an increased risk of osteoporotic fractures. Objective. To examine the association between cumulative CS dose and risk of hip fracture. Design. Population-based case,control design. Subjects and methods. A total of 6660 subjects with hip fracture and 33 272 age-matched population controls were identified using the County Hospital Discharge Registry in North Jutland County, Denmark and the Danish Central Personal Registry, respectively. Data on redeemed prescriptions for CS within the last 5 years before the index date were retrieved from a population-based prescription database, and recalculated to prednisolone equivalents. Cases and controls were categorized according to cumulative CS dose: (i) no use; (ii) <130 mg (e.g. equivalent to 30 mg of prednisolone for 4 days given for an acute exacerbation of asthma); (iii) 130,499 mg (e.g. equivalent to a short course of prednisolone of 450 mg for acute asthma); (iv) 500,1499 mg (e.g. equivalent to 7.5 mg prednisolone daily for 6 months or 800 ,g day,1 of inhaled budesonide for 1 year); and (v) ,1500 mg (e.g. equivalent to >4.1 mg day,1 for 1 year, a long-term high dose). Data were analysed using conditional logistic regression adjusted for potential confounders including gender, redeemed prescriptions for hormone replacement therapy, antiosteoporotic, anxiolytic, antipsychotic and antidepressant drugs. Results. Compared with never users, an increased risk of hip fracture was found for CS users, with increasing cumulative doses of any type of CS use during the preceding 5 years [adjusted odds ratio (OR) = 0.96, 95% confidence interval (CI) = 0.89,1.04] for <130 mg prednisolone; OR = 1.17 (CI = 1.01,1.35) for 130,499 mg; OR = 1.36 (CI = 1.19,1.56) for 500,1499 mg; and OR = 1.65 (CI = 1.43,1.92) for ,1500 mg. An increased risk was also found when the study population was stratified according to gender, age and type of CS (systemic or topical). Conclusions. Even a limited daily dose of CS (more than an average dose of approximately 71 ,g prednisolone per day) was associated with an increased risk of hip fracture. [source]


    Cyamemazine metabolites: effects on human cardiac ion channels in-vitro and on the QTc interval in guinea pigs

    JOURNAL OF PHARMACY AND PHARMACOLOGY: AN INTERNATI ONAL JOURNAL OF PHARMACEUTICAL SCIENCE, Issue 11 2008
    William Crumb
    Monodesmethyl cyamemazine and cyamemazine sulfoxide, the two main metabolites of the antipsychotic and anxiolytic phenothiazine cyamemazine, were investigated for their effects on the human ether-à-go-go related gene (hERG) channel expressed in HEK 293 cells and on native INa, ICa, Ito, Isus or IK1 of human atrial myocytes. Additionally, cyamemazine metabolites were compared with terfenadine for their effects on the QT interval in anaesthetized guinea pigs. Monodesmethyl cyamemazine and cyamemazine sulfoxide reduced hERG current amplitude, with IC50 values of 0.70 and 1.53 ,M, respectively. By contrast, at a concentration of 1 ,M, cyamemazine metabolites failed to significantly affect INa, Ito, Isus or IK1 current amplitudes. Cyamemazine sulfoxide had no effect on ICa at 1 ,M, while at this concentration, monodesmethyl cyamemazine only slightly (17%), albeit significantly, inhibited ICa current. Finally, cyamemazine metabolites (5 mg kg,1 i.v.) were unable to significantly prolong QTc values in the guinea pig. Conversely, terfenadine (5 mg kg,1 i.v.) significantly increased QTc values. In conclusion, cyamemazine metabolite concentrations required to inhibit hERG current substantially exceed those necessary to achieve therapeutic activity of the parent compound in humans. Moreover, cyamemazine metabolites, in contrast to terfenadine, do not delay cardiac repolarization in the anaesthetized guinea pig. These non-clinical findings explain the excellent cardiac safety records of cyamemazine during its 30 years of extensive therapeutic use. [source]


    Significant psychological morbidity occurs in irritable bowel syndrome: a case-control study using a pharmacy reimbursement database

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 4 2009
    J. B. CANAVAN
    Summary Background, Psychological problems are associated with IBS but the strength of this association is unclear. Aim, To assess co-prescribing of antispasmodic and CNS-acting drugs through a nested case-control study. Methods, A national dispensing database identified patients who were first dispensed antispasmodic medicines for a continuous 3-month period or more during 2006, using 2005 as a run-in period. Each patient was matched with four control patients and excluded if they received drugs indicated for IBD. Results, Four hundred and seven patients commenced antispasmodic drugs during 2006. These patients were matched with 1628 controls. In 2005, patients subsequently prescribed antispasmodics were 2,3 times more likely to receive CNS-acting drugs than controls. In the year following commencement of IBS therapy, patients were 2,4 times more likely than controls to be prescribed CNS-acting drugs including antidepressants (35.4% vs. 9.3%), anxiolytics (27.8% vs. 8.8%), antipsychotics (9.8% vs. 3.3%) and hypno-sedatives (32.7% vs. 11.3%; P < 0.0001). The adjusted OR (95% CI) for antidepressant, anxiolytic, hypnosedative and antipsychotic prescribing in IBS patients were 3.81 (2.79,5.20), 2.84 (2.12,3.81), 2.62 (1.91,3.60) and 2.58 (1.80,3.66), respectively. Conclusions, Patients prescribed ongoing therapy for presumed IBS are 2,4 times more likely to be prescribed CNS-acting drugs than controls, providing evidence of psychological comorbidity in IBS.

    Antipsychotic drugs and short-term mortality after peptic ulcer perforation: a population-based cohort study

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 7 2008
    C. CHRISTIANSEN
    Summary Background, Peptic ulcer perforation is a serious surgical emergency with a substantial short-term mortality, but the influence of antipsychotic drug use on the prognosis remains unknown. Aim, To examine the association between antipsychotic drug use and 30-day mortality following peptic ulcer perforation. Methods, This cohort study comprised 2033 patients with a first-time hospitalization with peptic ulcer perforation, in Northern Denmark, between 1991 and 2004. Data on preadmission use of antipsychotics and other medications, psychiatric disease, other comorbidities and mortality were obtained through population-based medical databases. We used Cox regression analyses to compute adjusted mortality rate ratios (MRRs). Results, One hundred and sixteen (5.7%) patients with peptic ulcer perforation were current users of antipsychotic drugs at the time of hospital admission and 205 (10.1%) were former users. The overall 30-day mortality was 27%. Among current users of antipsychotics 30-day mortality was 39%. The adjusted 30-day MRR for current users of antipsychotic drugs compared with non-users was 1.7 (95% CI: 1.2,2.3). Former use was not a predictor of mortality. The increase in mortality was equal in users of conventional and atypical antipsychotics. Conclusion, Use of antipsychotic drugs is associated with substantially increased mortality following peptic ulcer perforation. [source]


    Somnolence effects of antipsychotic medications and the risk of unintentional injury,,

    PHARMACOEPIDEMIOLOGY AND DRUG SAFETY, Issue 4 2008
    Qayyim Said PhD
    Abstract Purpose This study examined the relationship between antipsychotic medications, categorized by published somnolence effects, and unintentional injury (UI). Methods The study population included patients of 18,64 years of age in a healthcare insurance database with claims from 2001 to 2004 and diagnoses of schizophrenia or affective disorder. A nested case-control design was used with cases defined by an E-code claim (a specified external cause of injury) for selected UIs. For cases, the index date referred to the first injury. For controls, the "control index date" was the date of claim if there was only a single medical claim; for patients with ,2 claims, one was selected at random as the "control index date." Both groups had a prescription for a first-generation antipsychotic (FGA) or second-generation antipsychotic (SGA) overlapping the index date. Potential somnolence effects were defined as: low (referent) , aripiprazole/ziprasidone; medium , risperidone; high , olanzapine/quetiapine: or any single FGA. Logistic regression models were used to estimate odds ratio (OR) and 95% confidence interval (CI) for UI, adjusted for gender, age, concomitant drug, and psychiatric diagnosis. Results Among 648 cases and 5214 controls, high-somnolence SGAs were associated with an OR of 1.41 95%CI (1.03,1.93) for risk of UI, while medium-somnolence SGAs, and FGAs had ORs of 1.17 95%CI (0.83,1.64) and 1.17 95%CI (0.79,1.74), respectively. When quetiapine and olanzapine were disaggregated, ORs were 1.61 95%CI (1.15,2.25) and 1.25 95%CI (0.89,1.74), respectively. Conclusions High-somnolence SGAs may lead to UI among patients. When prescribing antipsychotics, clinicians should consider potential somnolence. Copyright © 2008 John Wiley & Sons, Ltd. [source]


    Exploring the risk of diabetes mellitus and dyslipidemia among ambulatory users of atypical antipsychotics: a population-based comparison of risperidone and olanzapine,

    PHARMACOEPIDEMIOLOGY AND DRUG SAFETY, Issue 6 2005
    Jocelyne Moisan PhD
    Abstract Purpose To compare the incidence rates of diabetes mellitus and dyslipidemia in ambulatory first-time users of risperidone and olanzapine. Methods The database for the Prescription Drug Insurance Plan in the province of Quebec was used as the data source for a population-based cohort study. Denominalized data were extracted for all ambulatory patients who first received an atypical antipsychotic between 1 January 1997 and 31 August 1999. Eligible patients were categorized as taking: no antidiabetic medication; no lipid reducing medication; neither type of medication. Those who started to use an outcome drug (an antidiabetic or lipid-lowering medication) before the end of the follow-up period (31 August 2000) were considered to have developed the corresponding outcome disease. Incidence rate ratios (IRR) (and 95% confidence intervals) for initiating antihyperglycemic or lipid-lowering drug treatment, or both were calculated. Outcomes on risperidone were compared to those on olanzapine. Results A total of 19,582 eligible patients were included in the analysis. Relative to risperidone, olanzapine was associated with a higher risk of initiating a pharmacologic treatment for diabetes [IRR: 1.33 (1.03,1.74)], dyslipidemia [IRR: 1.49 (1.22,1.83)], or either condition [1.47 (1.23,1.76)]. Conclusions Olanzapine seems to be associated with a higher risk of developing diabetes and/or dyslipidemia than risperidone. Further prospective studies are needed to rigorously assess the safety of olanzapine. Copyright © 2005 John Wiley & Sons, Ltd. [source]


    Healthcare resource utilization during 1-year treatment with long-acting, injectable risperidone,

    PHARMACOEPIDEMIOLOGY AND DRUG SAFETY, Issue 11 2004
    A. Leal
    Abstract Background Schizophrenia is associated with disproportionately high costs, mainly due to hospitalization rates. This study assessed healthcare resource use in patients with schizophrenia and schizoaffective disorder during treatment with long-acting risperidone. Methods Patients (n,=,397 [inpatients, 24%; outpatients, 76%]) receiving stable doses of an antipsychotic for ,4 weeks were eligible to enter this 1-year, open-label study. Following a 2-week run-in period (oral risperidone 1,6 mg/day), patients received intramuscular long-acting risperidone (25 or 50 mg modal dose) every 2 weeks. Healthcare resource use in the previous 12 weeks was assessed at baseline and 12-weekly intervals. Results Patients needing hospitalization decreased significantly and continuously from 38% during the 12 weeks before study entry to 12% during the last 12 weeks. Mean hospitalization length during the study was 30.5 days (outpatients, 4.9 days; inpatients, 110 days). This included 28 patients (7%) who remained in hospital throughout the study. During treatment, 71% of those hospitalized at baseline were discharged. Partial hospitalization decreased significantly from 7% of patients during the 12 weeks before treatment to 3% during the last 12 weeks. Outpatient consultations also decreased significantly from 70% of patients to 30% in the first 12 weeks of treatment and remained stable thereafter. Only 9% of patients required an emergency room visit; mostly for non-psychiatric conditions. Conclusion Healthcare resource use is significantly reduced in patients with stable schizophrenia or schizoaffective disorder receiving long-acting risperidone. It is highly likely that these reductions will decrease healthcare costs in patients receiving long-acting risperidone. Copyright © 2004 John Wiley & Sons, Ltd. [source]
