Other Antipsychotics (other + antipsychotics)
Selected AbstractsAugmentation with sulpiride for a schizophrenic patient partially responsiveto clozapineACTA PSYCHIATRICA SCANDINAVICA, Issue 5 2000Jean 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] Genetic association between TNF-, ,308 G>A polymorphism and longitudinal weight change during clozapine treatmentHUMAN PSYCHOPHARMACOLOGY: CLINICAL AND EXPERIMENTAL, Issue 4 2010Ying-Chieh Wang Abstract Objective The aim of the study was to investigate the association between genetic variation in the tumor necrosis factor-alpha (TNF-,) gene and longitudinal weight change during long-term clozapine treatment. Methods Fifty-five patients with refractory schizophrenia treated with clozapine for 8 years were recruited. Gender, age, treatment response to clozapine in the first 14 months, baseline BMI, clozapine dose, concomitant use of mood stabilizers and other antipsychotics, and ,308 G,>,A polymorphism in the human TNF-, gene were analyzed using generalized estimating equations. Results In addition to having a lower baseline BMI (p,=,0.0013) and a longer treatment time (p,=,0.050), the ,308 GG carriers gained significantly more weight than the ,308 A allele carriers (p,=,0.0084) during 8 years of clozapine treatment, after controlling for other non-genetic factors. Conclusions The ,308 G,>,A genetic variant of the TNF-, gene is associated with longitudinal weight change during clozapine treatment. Follow-up duration is an important factor to consider when performing pharmacogenetic study of clozapine-induced weight gain. Copyright © 2010 John Wiley & Sons, Ltd. [source] 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 2009J. 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] Alterations of liver function test in patients treated with antipsychoticsJOURNAL OF CLINICAL LABORATORY ANALYSIS, Issue 6 2003M. Teresa Garcia-Unzueta Abstract The prevalence of alterations of liver function tests in patients treated with a wide range of antypsychotics is unknown. The aim of this study was to analyze the effects of antipsychotics on liver function tests in a population of schizophrenic outpatients. Concentrations of AST, ALT, GGT, alkaline phosphatase, albumin, and bilirubin were determined in 54 patients fitting DSM-IV criteria of schizophrenia, and the same number of sex- and age-matched healthy subjects. Assessments included the Clinical Global Impression (CGI) and the Positive and Negative Syndrome Scale (PANSS) in addition to treatment related variables. Transaminases concentrations were slightly elevated in study patients compared to healthy controls, but without statistical significance. Alkaline phosphatase showed higher values in schizophrenic patients. Albumin and bilirubin were lower in study patients. Liver function tests abnormalities were found in about 10% of schizophrenic patients treated with antipsychotics. Treatment with depot phenotiazines induces alteration in these tests more frequently than treatment with other antipsychotics. PANSS negative subscale scores directly correlated with alkaline phosphatase and inversely correlated with albumin. A substantial number of patients in treatment with antipsychotic drugs present alterations of liver function tests. Both pharmacological and clinical factors could be related with these alterations.

[source] The effectiveness of antipsychotic medication in the management of behaviour problems in adults with intellectual disabilitiesJOURNAL OF INTELLECTUAL DISABILITY RESEARCH, Issue 10 2007S. Deb Abstract Background Psychopharmacological intervention in the management of behaviour problems in adults with intellectual disabilities (ID) has become a common treatment strategy. This has become a cause for concern, given that the evidence for its effectiveness is uncertain and most drugs are not licensed for this use. Methods A comprehensive systematic review of empirical research on the effectiveness of antipsychotic medication was conducted. Electronic and manual searches of literature were conducted. Stringent scientific methodology determined those primary trials that were worthy of inclusion. Results This review revealed one randomized controlled trial (RCT), one controlled, four uncontrolled prospective and three retrospective case series studies in adults. Additionally, two studies in both adults and children , one crossover RCT and one prospective controlled trial , were found. Conclusion Presently, there is RCT-based evidence for risperidone to be effective in both adults and children; however, this treatment carries a certain amount of risk associated with adverse effects. There is also evidence to support the use of other antipsychotics, primarily atypicals, but the evidence is based on noncontrolled case studies. There is currently not enough evidence available to recommend specific medication for specific behaviour problems. Before prescribing medication, clinicians should carry out a thorough assessment of behaviour, including its causes and consequences, and draw up a formulation providing the rationale for the prescribed intervention after considering all medication- and nonmedication-based management options. [source] The Prescribing Pattern of a New Antipsychotic: A Descriptive Study of Aripiprazole for Psychiatric In-Patients,BASIC AND CLINICAL PHARMACOLOGY & TOXICOLOGY, Issue 1 2008Stig 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] | ||||||||||
