Evaluation of adverse drug reactions in patients of schizophrenia in tertiary care teaching hospitals in Central India

Background: For decades, it has been observed that mental health is shrouded in stigma and discrimination. The scope, severity, and expense of impairment and costs to people, families, and societies are staggering. Mental illnesses are among the most frequent illnesses, affecting over a quarter of the population in any given year. According to national institute of mental health and neurosciences, Bangalore, the prevalence of schizophrenia has been considered as 4/1000 for all ages and both sexes. Aim and Objectives: The objectives of this study were to as follows: (1) To evaluate adverse drug reactions (ADRs) in patients with schizophrenia who received antipsychotic treatment and (2) to compare ADRs in typical versus atypical antipsychotic agents in schizophrenic patients. Materials and Methods: A total of 50 schizophrenic patients were enrolled for evaluating adverse effects to antipsychotic drugs. During the research, all ethical precautions were taken. All patients were followed up by medical history, history of drugs, and any severity of adverse drug reaction. Causality assessment was graded by Naranjo scale. Result: Among all of the antipsychotic drugs, risperidone (05%), quetiapine (04%), and aripiprazole (04%) have shown lowest propensity to cause serious adverse event. These drugs are most commonly prescribed drugs and are least likely to affect quality of life of patient. However, the risk of extrapyramidal symptoms is lower with olanzapine (05%) than haloperidol (34%) and even in case with risperidone at higher dose (20%). Although atypical antipsychotics such as olanzapine (46%) have shown maximum potential to produce metabolic side effect such as dyslipidemia and hyperglycemia compared to that of other antipsychotics. Conclusion: The most common adverse effects were found with typical and atypical antipsychotics such as weight gain, drowsiness, constipation, sedation, dyslipidemia, and hypotension.

Relationship between ANKK1 gene polymorphism and atypical antipsychotic drug-induced metabolic syndrome / 中国药房

OBJECTIVE To explore the relationship between the ANKK1 rs1800497 polymorphism and atypical antipsychotic drug-induced metabolic syndrome （MS）. METHODS Totally 94 patients with schizophrenia were included， and ANKK1 rs1800497 genotypes of patients were detected by micro-fluorescence immunoassay； social demographic information， clinical characteristics and other data were collected. The χ2 test was used to compare the correlation between the sex of patients and the occurrence of MS， and the correlation between gene polymorphism and the occurrence of MS and its risk factors.RESULTS Totally 94 patients included 24 cases （25.53%） of GG， 51 cases （54.26%） of GA and 19 cases of AA （20.21%）. Among them， there were 45 cases （47.87%） of MS， and the incidence of MS in male was higher than that in female （P＜0.05）. Genotype analysis showed that ANKK1 rs1800497 polymorphism was not associated with MS （P＝0.452）. ANKK1 rs1800497 A allele was significantly associated with hyperglycemia （χ2＝4.379， P＝0.036）， while it was not related to abdominal obesity， hypertension， high level of TG and low level of HDL-C （P＞0.05）， suggesting that for patients with schizophrenia， allele A was a relative risk factor for inducing hyperglycemia [OR＝2.008，95%CI（1.039， 3.881）]. CONCLUSIONS ANKK1 rs1800497 polymorphism has no correlation with the induction of MS by atypical antipsychotics， while the schizophrenia patients with A allele are more likely to induce hyperglycemia. The incidence of MS in male patients is significantly higher than that in female patients.

Combinación de antidepresivos vs. aumentación con antipsicóticos atípicos tras no lograr la remisión en la depresión unipolar / Combination of antidepressants vs. augmentation with atypical antipsychotics upon failure to achieve remission in unipolar depression

RESUMEN: Introducción: Lograr la recuperación funcional lo más rápido posible en el tratamiento de la depresión unipolar es un reto que la práctica clínica debe tratar de afrontar en la actualidad, ya que cualquier retraso en lograr la remisión de los síntomas es predictivo de un mayor número de recurrencias y mayores tasas de morbimortalidad. En esta revisión comprensiva, nuestro objetivo es guiar a los clínicos en su elección de aumentar con antipsicóticos atípicos o combinar el fármaco de referencia con un segundo antidepresivo, después de que se haya optimizado la dosis del antidepresivo seleccionado inicialmente y/o se haya cambiado el antidepresivo, sin lograr remisión, o bien cuando solo han obtenido una respuesta parcial después de un tiempo suficiente a una dosis apropiada. Estas decisiones surgen con frecuencia en la práctica clínica diaria. Metodología: Se realizó una búsqueda sistemática en PubMed bajo varias combinaciones clave de palabras, resultando en 230 informes. Después de aplicar los criterios de inclusión y según el título y el resumen, el número final de informes seleccionados para la revisión completa fue de 113. Se respondieron dos preguntas principales con base en estos estudios: 1) ¿Existe evidencia para recomendar claramente la combinación de antidepresivos versus potenciación con antipsicóticos (y el momento correcto para hacerlo) en la depresión unipolar no respondedora, una vez que las estrategias de optimización o de cambio han fallado en obtener la remisión? y 2) ¿Es posible identificar algunas características clínicas para guiar la decisión de combinación de antidepresivos versus potenciación con agentes antipsicóticos? Resultados: Según nuestro análisis, no hay datos disponibles para seleccionar una estrategia de otra de manera clara. Sin embargo, sugerimos favorecer una combinación o estrategia de aumento, basada en un enfoque de "tratamiento contra objetivos dianas" para perfilar al paciente, considerando una o dos características clínicas predominantes que permanecen activas como parte de una depresión mayor con respuesta parcial. Un adecuado análisis de los dominios sintomáticos presentes, una visión crítica de las guías clínicas actuales y de las opciones preferidas, considerar la bipolaridad oculta como uno de los principales diagnósticos diferenciales y adoptar una actitud enérgica pero lúcida en esta etapa del tratamiento son, a nuestro juicio, fundamentales para lograr recuperación ad integrum del paciente.

ABSTRACT Introduction: achieving functional recovery as quickly as possible in the treatment of unipolar depression is a challenge that clinical practice must try to meet nowadays, since any delay in accomplishing remission of the symptoms is predictive of a larger number of recurrences and higher morbidity and mortality rates. In this topical review we aim to guide clinicians in their choice to augment with atypical antipsychotics or to combine the baseline drug with a second antidepressant, after the dose of the antidepressant initially selected has been optimized and/or the antidepressant has been changed, not achieving remission, or resulting only in a partial response after sufficient time at an appropriate dose. These decisions arise frequently in everyday clinical practice. Methodology: a systematic search in PubMed was performed under several key combinations of words, resulting in 230 reports. After applying inclusion criteria and based in title and abstract, the final number of reports selected for full revision were 113. Two main questions were answered based on these studies: 1) Is there evidence to clearly recommend combination of antidepressants vs. augmentation with antipsychotics (and the correct moment to do it) in non-responsive unipolar depression, once optimization or switching strategies have failed to obtain remission? and 2) Is it possible to identify some clinical features to guide the decision of combination of antidepressants vs. augmentation with antipsychotic agents? Results: According to our analysis, there is no data available to select one strategy from another in a clear-cut manner. Nevertheless, we suggest favoring a combination or augmentation strategy, based in a "treating to target" approach to profile the patient, considering one or two predominant clinical features that remain active as part of a major depression with partial response. Proper analysis of the symptomatic domains present, a critical view of current clinical guidelines and preferred options, considering hidden bipolarity as one of the main differential diagnoses and adopting an energetic but lucid attitude at this stage of treatment are, in our view, fundamental for achieving ad integrum patient recovery.

Antipsychotics as a probable cause of Leukocytoclastic Vasculitis: A Systematic Review

Abstract: Leukocytoclastic vasculitis (LCV) is a skin condition that is a result of unregulated immune activation. The exact causes have to date not been established. The studied causes tend to have a higher probability of causing LCV. This raises concerns about a deep-seated causal relationship and the tendency of an individual for the development of LCV. Antipsychotics are a class of drug mainly used for psychiatric disorders including schizophrenia, schizophreniform disorder, or even depressive disorder with psychotic features. These drugs target the dopamine receptors in the central nervous system to exert their effects. They are classified as typical or the older antipsychotics and atypical or the newer antipsychotics. Prevalent in the current literature are the reported cases of LCV with antipsychotic medications. We carried out a systematic review following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analysis) protocol to find out previously reported cases on LCV due to antipsychotic medication administration from inception till current date. Our study aims to check and in turn, discuss the causal relationship of antipsychotics with LCV.

Efficacy and safety of atypical antipsychotics combined with selective serotonin reuptake inhibitors in the treatment of refractory obsessive-compulsive disorder： a network Meta-analysis / 四川精神卫生

ObjectiveTo evaluate the efficacy and safety of 7 atypical antipsychotics combined with selective serotonin reuptake inhibitors（SSRIs） in the treatment of refractory obsessive-compulsive disorder by network Meta-analysis. MethodsRandomized controlled trials （RCTs） about atypical antipsychotics and SSRIs in the treatment of refractory obsessive-compulsive disorder were searched in CNKI， Wanfang Data， VIP， CBM， PubMed， Embase and Cochrane Library databases from inception to June 2020. Based on inclusion and exclusion criteria， the literature screening， date extraction and assessing risk of bias were performed by two researchers independently. Then all statistical analyses were performed using Stata 15.0 software. ResultsA total of 36 RCTs covering 7 atypical antipsychotics and 2 362 patients were included. Network Meta-analysis showed that the surface under the cumulative ranking （SUCAR） of total response rate was the largest in Olanzapine + SSRIs， followed by Paliperidone + SSRIs， Amisulpride + SSRIs， Risperidone + SSRIs， Quetiapine + SSRIs， Ziprasidone + SSRIs， Aripiprazole + SSRIs， SSRIs， and Placebo + SSRIs in turn. In terms of Hamilton Anxiety Scale （HAMA） score， the SUCAR was the largest in Amisulpride + SSRIs， followed by Aripiprazole + SSRIs， Quetiapine + SSRIs， Risperidone + SSRIs， and SSRIs in turn. In terms of Treatment Emergent Symptom Scale （TESS） score， the SUCAR was the largest in Amisulpride + SSRIs， followed by SSRIs， Paliperidone + SSRIs， Quetiapine + SSRIs， Ziprasidone + SSRIs， Risperidone + SSRIs， Aripiprazole + SSRIs， and Placebo + SSRIs in turn. ConclusionCompared with single application of SSRIs， its combination with atypical antipsychotics achieves better efficacy and higher safety in treating refractory obsessive-compulsive disorder， with Olanzapine+SSRIs being the most effective and Amisulpride+SSRIs the safest.

Effects of typical or atypical antipsychotics on cognitive symptoms of the patients with schizophrenia / 上海交通大学学报（医学版）

Objective: To compare the effects of long-term use of typical and atypical antipsychotics on cognitive symptoms of the patients with schizophrenia. Methods: One hundred and two long-term inpatients with schizophrenia in Shanghai Jinshan Mental Health Center were included. According to the types of antipsychotics, the inpatients were divided into typical antipsychotics treatment group (typical group) or atypical antipsychotics treatment group (atypical group) with 51 cases each. Mental symptoms were evaluated by Positive and Negative Symptom Scale (PANSS), and cognitive symptoms were evaluated by Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). Results: Ninety-nine patients completed the investigation (49 cases in typical group and 50 cases in atypical group). PANSS score: the negative symptom score in the atypical group was lower than that in the typical group, and the difference was statistically significant (P=0.049). RBANS score: The total score of RBANS and the scores of immediate memory, language, attention and delayed memory in the atypical group were significantly higher than those in the typical group (all P<0.05). Conclusion: Compared with the patients who take typical antipsychotics, the patients with schizophrenia who take atypical antipsychotics for a long time have better cognitive symptom scores.

Efficacy of risperidone and haloperidol in treatment of schizophrenia in tertiary care hospital

Background: Schizophrenia is a chronic debilitating disease with significant morbidity and mortality that often requires either typical or atypical antipsychotic pharmacotherapy. Atypical antipsychotic drugs are preferred over typical because of lower risk of extra pyramidal side effects. As there is paucity of data in Indian population, the present study was taken up to evaluate the efficacy of haloperidol and risperidone in the treatment of schizophrenia.Methods: It was a comparative study conducted on 60 patients of Schizophrenia for one year in a tertiary care hospital. The study subjects were randomly assigned into 2 groups of 30 patients each, where group 1 were treated with atypical antipsychotic drug risperidone and group 2 with typical antipsychotic drug Haloperidol and both groups received the treatment for one year. Efficacy was measured using positive and negative syndrome scale (PANSS), clinical global impression - severity of illness (CGI-S), clinical global impression - improvement (CGI-I) scales.Results: Both haloperidol and risperidone were associated with comparable baseline to endpoint reduction in symptom severity. However, risperidone treated subjects had significantly greater decrease in symptom severity as measured by PANSS score and total score, CGI-S scale. However, there is no significant difference between two groups in terms of CGI-S score.Conclusions: The reduction in positive, negative and general scores in risperidone treated patients were significant with that of haloperidol treated patients.

A comparative study of metabolic side effects of risperidone and olanzapine in the treatment of schizophrenia

ABSTRACTBackground: Schizophrenia is one of most serious chronic psychiatric disorder, which affects about 1% of population. Treatment of schizophrenia comprises of typical antipsychotics and or atypical antipsychotics. Typical antipsychotics like haloperidol have extrapyramidal side effects which limit their use in chronic cases. Atypical antipsychotics though have better treatment response, they have metabolic side effects like hypercholesteremia, hypertriglyceridemia and hyperglycaemia. As there is paucity of data in Indian population the present study has been taken up to compare the metabolic side effects of risperidone and olanzapine in the treatment of schizophrenic patients in a tertiary care hospital.Methods: It was a comparative study conducted on 60 patients of Schizophrenia for one year in a tertiary care hospital. The study subjects were randomly assigned into 2 groups of 30 patients each, where group 1 were treated with atypical antipsychotic drug risperidone and group 2 with Olanzapine and both groups received the treatment for one year. Metabolic side effects like hypercholesteremia, hypertriglyceridemia and hyperglycaemia were evaluated and compared over a period of one year.Results: Both risperidone and olanzapine were associated with comparable baseline to endpoint increase in metabolic side effects. However, risperidone treated subjects had significantly less metabolic side effects compared to olanzapine.Conclusions: Apart from total cholesterol and triglycerides, other metabolic side effects were less in risperidone treated patients than olanzapine treated patients.

Antipsychotic Prescribing Pattern In Elderly Patients With Psychiatric Disorders

The elderly people are more prone to develop psychiatric disorders due to a number of factors like changes in the brain, other illnesses etc. They represent the most vulnerable group as they are most sensitive to the effects of drugs and are at increased risk of developing adverse drug reactions. This warrants the need to make the prescribers cautious about rational prescribing of antipsychotics to the Elderly. The study included elderly inpatients and outpatients visiting psychiatry ward with psychiatric disorders. Descriptive weighed analysis was performed to determine the prescribing practices of atypical antipsychotics. Among the 70 patients who were involved in the study, 36 patients were diagnosed with neurotic disorders and 30 patients were diagnosed with psychotic disorders and 4 were diagnosed with degenerative disorders (dementia). In our study neurotic disorders (51%) were the major diagnosis. 6 different atypical antipsychotic drugs were prescribed to the patients suffering from different psychiatric disorders. Among them olanzapine (43%) was the most commonly prescribed drug, followed by quetiapine (30%), risperidone (21%), clozapine (3.2%), lurasidone (1%), and aripiprazole (1%). This study has concluded that atypical antipsychotics are preferred over typical antipsychotics and Olanzapine is the most commonly prescribed drug for the elderly patients suffering from psychiatric disorders. On comparison of the prescribed daily doses with the maximum daily dose we have observed that the prescribed daily doses for the elderly patients were well within the maximum daily dose of the drugs and in our study no adverse drug reactions were reported in the study subjects that were involved.

Delirium in the Critically Ill Patients: Is It Easily Diagnosed? What is the Incidence and What is the Management?

Introduction: Delirium is common in critically sick patients and related prolonged length of medical intensive care unit (ICU) and long-run psychological impairment. Aim of the study: The aim of the study is to assess the incidence of delirium in critically ill patients. Evaluate the effectiveness of diagnosing delirium by subjective global assessment compared to CAM-ICU score in critically ill patients. Evaluate the effect of haloperidol versus atypical antipsychotic drugs in the treatment. Methods: Total 200 critically ill patients selected sequentially on their admission to ICU and subjected for full medical history taking, clinical examination daily with emphasis on full neurological assessment, daily assessment of delirium along their stay in the ICU by 2 methods: subjective global assessment which is the subjective individual clinical impression performed by the attending resident in the ICU. CAM-ICU score which is performed by the physician in charge of the study using CAM-ICU worksheet. Results: Delirium is a frequent complication in the intensive care unit. The CAM-ICU scoring system appears to be rapid, valid, and reliable for diagnosing delirium in the ICU setting and may be a useful instrument for both clinical and research purposes. Use of objective criteria may identify patients mistakenly thought to have delirium who do not meet objective criteria for the diagnosis of the condition. The degree of agitation is an essential indicator of the dosage of the used antipsychotic drug, need for additional antipsychotics. Conclusion: Delirium is a common problem in critically ill patients and is not easy to manage.

Pharmacoepidemiological survey of schizophrenia in a tertiary care teaching hospital

Background: Prevalence of chronic schizophrenia is somewhat less than 1% of the population but this is one of the most important psychiatric illness due to its early onset, chronicity and associated disability.Methods: A prospective and observational study was carried out on 76 patients for 12 months. Patients of either sex, aged between 18 to 50 years who were diagnosed as schizophrenia according to DSM IV-TR were screened and recruited for the study. Prescriptions were analyzed for socio demographic details and psychotropic drugs prescribed.Results: Out of 76 patients 46 (60.53%) were males, maximum occurred 19 (41.30%) between 18 and 25 years of age. Females were 30 (39.47%), maximum occurred 12 (40%) between 34 - 39 years of age. 52 (68.42%) were from urban area and 24 (31.57%) were from rural area. 26 (34.21%) were illiterate, 24 (31.58%) primary educated, 16 (21.05%) secondary educated and 10 (13.16%) higher secondary and above. 20 (26.32%) were unemployed, students 9 (11.84%), housewives 19 (25%), agricultural workers 10 (13.16%), nonagricultural outdoor workers 4 (5.26%) and nonagricultural indoor workers were 14 (18.42%). Only atypical antipsychotics were prescribed .Olanzapine was prescribed in 30 (39.47%), risperidone 16 (21.05%), amisulpride 13 (17.11%), aripiprazole 11 (14.47%) and quetiapine 06 (7.89%) respectively.Conclusions: The sociodemographic factors associated with schizophrenia are urban locality, illiteracy, low socioeconomic status and unemployment. The treatment pattern observed correlates with the changing trends in the treatment of schizophrenia worldwide.

A comparative study of the efficacy of amisulpride and olanzapine in patients with schizophrenia attending the outpatient Department of Psychiatry in a tertiary care hospital, Silchar, Assam, India

Background: Schizophrenia is one of the most commonly encountered psychiatric disorders. It is characterized by impairment in perception or expression of reality, leading to occupational and social dysfunction. Now a day’s mainstay of treatment of schizophrenia is by using atypical antipsychotics. Amisulpride and olanzapine are atypical antipsychotics which are commonly used in treatment of schizophrenia. The current study is undertaken to assess the efficacy of amisulpride which is a relatively newer antipsychotics against existing antipsychotic olanzapine.Methods: This was designed as a single-blind, prospective, parallel-group, observational study. Eighty adult patients of either sex were randomized to receive standard doses of the two drugs orally for 12 weeks, with follow up at 4 and 8 weeks. Effectiveness was assessed by change in the score of Brief Psychiatric Rating Scale (BPRS) and Clinical Global Impression (CGI) score during the treatment period. Data were entered in Microsoft excel and statistical analysis were done using graph pad and p value <0.05 considered to be statistically significant.Results: Out of 80 adults patients 76 patients were evaluated by dividing into two groups, 38 patients were included in each group. Final BPRS score was less for olanzapine as compared to amisulpride (p<0.001). Improvement in CGI score is more in olanzapine group than amisulpride group which became statistically significant from 8th weeks onwards.Conclusions: Both amisulpride and olanzapine are very effective in controlling the symptoms of schizophrenia which is evident by significant decrease in BPRS, CGI-S and CGI-I score, but efficacy of amisulpride is still inferior to olanzapine.

Does Melatonin and Melatonin Agonists Improve the Metabolic Side Effects of Atypical Antipsychotics?: A Systematic Review and Meta-analysis of Randomized Controlled Trials

Atypical antipsychotics (AAPs) are increasingly used for the treatment of psychotic disorders but are known to be associated with metabolic abnormalities. This study is a systematic review and meta-analysis of randomized controlled trials (RCTs) studying the effectiveness of melatonin for the amelioration of AAP-induced metabolic syndrome. The MEDLINE (accessed via PubMed), Cochrane Central Register of Controlled Trials (CENTRAL), ClinicalTrials, PsycINFO, LILACS, CINAHL, and OpenGrey databases were searched for RCTs without language restrictions. Inclusion criteria were randomized, double-blind clinical trials comparing melatonin or melatonin agonists with placebo for the amelioration of AAP-induced effects at any age with selected components of metabolic syndrome as outcome measures. Two reviewers independently selected articles and assessed quality using Cochrane risk of bias and concealment tools. Of 53 records, five RCTs were eligible for the systematic review and three for the meta-analysis. The meta-analyses showed no statistically significant difference in any anthropometric or metabolic variable considered. Analysis according to psychiatric diagnosis from one RCT showed significant decreases in diastolic blood pressure (5.5 vs. −5.7 mmHg for the placebo and melatonin groups, respectively; p=0.001), fat mass (2.7 vs. 0.2 kg, respectively; p=0.032), and triglycerides (D) (50.1 vs. −20 mg/dl, respectively; p=0.08) in the bipolar group but not the schizophrenia group. Although limited to five RCTs with small sample sizes, evidence from RCT indicates that melatonin improves AAP-induced metabolic syndrome. This beneficial effect seems more significant in patients with bipolar disorder than those with schizophrenia. Further RCTs are needed to definitively establish the potential ameliorative effect of melatonin and to justify its efficacy as an add-on therapy to curtail AAP-induced metabolic syndrome.

Pharmacological Treatment Strategies for Acute Bipolar Depression / 신경정신의학

Of the different phases of bipolar disorder, bipolar depression is more prevailing and is more difficult to treat. However, there is a deficit in systemic research on the pharmacological treatment of acute bipolar depression. Therefore, consensuses on the pharmacological treatment strategies of acute bipolar depression has yet to be made. Currently, there are only three drugs approved by the Food and Drug Administration for acute bipolar depression : quetiapine, olanzapine-fluoxetine complex, and lurasidone. In clinical practice, other drugs such as mood stabilizers (lamotrigine, lithium, valproate) and/or the other atypical antipsychotics (aripiprazole, risperidone, ziprasidone) are frequently prescribed. There remains controversy on the use of antidepressants in bipolar depression. Here, we summarized the evidence of current pharmacological treatment options and reviewed treatment guidelines of acute bipolar depression from recently published studies.

A Bibliometric Analysis of Scientific Production on Second-Generation Anti- Psychotic Drugs in Malaysia

Objective: We carried out a bibliometric study on the scientific papers related to second generation anti-psychotic drugs (SGAs) in Malaysia. Methods: With the SCOPUS database, we selected those documents made in Malaysia whose title included descriptors related to SGAs. We applied bibliometric indicators of production and dispersion, as Price’s law and Bradford’s law, respectively. We also calculated the participation index of the different countries. The bibliometric data were also been correlated with some social and health data from Malaysia (total per capita expenditure on health and gross domestic expenditure on R&D). Results: We found 105 original documents published between 2004 and 2016. Our results fulfilled Price’s law, with scientific production on SGAs showing exponential growth (r = 0.401, vs. r = 0.260 after linear adjustment). The drugs most studied are olanzapine (9 documents), clozapine (7), and risperidone (7). Division into Bradford zones yields a nucleus occupied by the Medical Journal of Malaysia, Singapore Medical Journal, Australian and New Zealand Journal of Psychiatry, and Pharmacogenomics. Totally, 63 different journals were used, but only one in the top four journals had an impact factor being greater than 3. Conclusion: The publications on SGAs in Malaysia have undergone exponential growth, without evidence a saturation point.

Comparative Evaluation of Cost – Effectiveness and Medication Adherence Between Olanzapine and Iloperidone in Patients of Psychosis

Background: To assess the cost – effectiveness between Iloperidone and Olanzapine in relation to different measures of effectiveness and to evaluate significance of medication adherence and costs and outcomes. Methods: A prospective, randomized, comparative, flexible dose clinical study of 1 year duration was conducted in 100 first episode (drug naïve) cases of psychosis attending to psychiatric outdoor patient department of Rohilkhand Medical College and Hospital, Bareilly. 50 patients each in olanzapine (OLZ) and Iloperidone (ILO) group comprised the sample size. Patients were regularly evaluated by senior psychiatrist for dose titration. OLZ 10-20mg/day and ILO 6-12mg/day were used. Least expensive brands available in our hospital pharmacy were used. Cost – effectiveness and medication adherence were measured as per the formula. Results: It was observed that ILO (8mg/day) controlled 65-75% cases and 12mg/day dose controlled > 90% cases of psychosis. Whereas OLZ showed this level of control respectively with 10 – 15mg/day (average 12.5mg/day) and 15-20mg/day (average 17.5mg/d). Since olanzapine in 15-20mg/day dose cause more metabolic adverse events particularly obesity, hyperglycemia and dyslipidemia which need further management hence overall olanzapine is not cost-effective. 42(87.5%) cases had medication possession ratio (MPR) >90% in ILO group compared to 18 (37.5%) cases in OLZ group. Increased medication adherence led to better control and outcomes. Patients with <90% MPR had developed more adverse events and were mostly living in rural areas. Conclusions: Iloperidone is comparatively more cost-effective than olanzapine to control > 90% of patients on long term use.

Antipsicóticos de primera y segunda generación en esquizofrenia: eficacia, efectividad y efecto de la dosis utilizada / First and second generation antipsychotics in schizophrenia: efficacy, effectiveness and effect of the dose used

Después de varias décadas de desarrollo de los fármacos antipsicóticos, la esquizofrenia sigue siendo en gran medida una enfermedad crónica con muchos pacientes que experimentan una mala calidad de vida. En este contexto, la aparición de los llamados antipsicóticos de segunda generación fue recibida con gran entusiasmo. Los clínicos esperaban que los nuevos antipsicóticos causaran no solamente menos efectos secundarios motores que los más antiguos, tal como la clorpromazina, sino también que mejoraran los síntomas y la funcionalidad general de los pacientes. Este artículo, de carácter narrativo, revisa cómo inicialmente la evidencia de un gran número de ensayos controlados aleatorios pareció favorecer muchas de estas suposiciones. Esta visión, sin embargo, no era universal, y algunos investigadores destacaron el potencial efecto del diseño de los estudios en los resultados. Un aspecto importante dice relación con la dosis utilizada de antipsicóticos de primera generación, siendo aquellos ensayos que usaron mayores dosis los que apoyaron el uso de antipsicóticos de segunda generación. Esta controversia se resolvió después de la publicación de tres estudios a gran escala, que incluían pacientes menos seleccionados y que enfocaban los resultados a largo plazo en un entorno clínico más "típico", los cuales no encontraron diferencias significativas entre los dos tipos de antipsicóticos. Desde entonces, las discusiones sobre la elección de los antipsicóticos han girado en torno a otros factores tales como los efectos secundarios, más que en su capacidad para controlar los síntomas.(AU)

After several decades of antipsychotic medication development, schizophrenia has largely remained a chronic disease with many patients experiencing poor quality of life. In this context, the appearance of so-called second generation antipsychotics was received with great enthusiasm. Clinicians hoped that the new antipsychotics would not only cause less motor side effects than older ones such as Chlorpromazine, but also improve patients' symptoms and overall functioning. In this narrative article we review how initially the vidence of a large number of randomized controlled trials appeared to favour many of these claims. This view was not universal though, and some researchers highlighted the potential effect of some design aspects of the trials in the results. A particular concern related to the dose of first generation antipsychotic used, with trials favouring second generation frequently using higher doses. This controversy was resolved after the publication of three large studies, including less selected patients and looking at longer-term outcomes in a more "typical" clinical setting, which failed to find significant differences between the two types of antipsychotics. Since then, discussions about the choice of antipsychotic revolve more around other factors such as side-effects than their capacity to control symptom.(AU)

Relationship between Serum Bilirubin Levels and Metabolic Syndrome in Patients with Schizophrenia Spectrum Disorders

OBJECTIVE: We investigated the relationship between serum bilirubin levels and metabolic syndrome (MetS), and the longitudinal effects of baseline serum bilirubin concentrations on MetS in patients with schizophrenia spectrum disorders undergoing atypical antipsychotics. METHODS: The sample of this study consisted of 131 patients with schizophrenia spectrum disorders. Waist circumference, blood pressure, and levels of triglycerides, high-density lipoprotein cholesterol, fasting glucose, and insulin were evaluated at baseline and at month six. Serum bilirubin levels were measured at baseline. Serum bilirubin levels of the patients with and without MetS criteria were compared. We also compared patients with high and low bilirubin levels (upper and lower 50th percentiles of serum bilirubin levels) in terms of MetS criteria, MetS frequency, and course of MetS. RESULTS: Serum direct bilirubin levels were more consistently related to MetS and MetS-related variables. The waist circumference and triglyceride criteria for MetS were significantly related to low serum direct bilirubin at baseline; waist circumference and fasting glucose criteria, and insulin resistance were associated with low serum direct bilirubin at follow-up. MetS diagnosis and the presence of the waist circumference criterion were more frequent at the baseline and the follow-up in low bilirubin group. At the end of the follow-up period, the rate of reverse MetS was significantly higher in the high bilirubin group. CONCLUSION: Our results have suggested that serum direct bilirubin levels showed a more reliable and stable relationship with abdominal obesity for MetS components.in patients with schizophrenia spectrum disorders using antipsychotics. Further studies are required.

The Effects on Metabolic Syndrome Parameters of Atypical Antipsychotic Agents in Schizophrenics Patients : 3 Years Retrospective Follow Up / 대한정신분열병학회지

OBJECTIVES: Pharmacological treatment is critical on relapse prevention in patients with schizophrenia. However, atypical antipsychotic agents are known to cause weight gain more than typical agents despite their various effects. In addition, they are known to affect blood sugar, blood pressure, cholesterol, cardiac function, and sexual function. This study was designed to examine the effects on metabolic parameters when schizophrenic patients have been taken atypical antipsychotic agents. METHODS: This was a trial in 137 patients with DSM-IV-TR schizophrenia who were admitted or treated in mental hospital. Anthropometric measurement and blood testing were conducted at baseline, 12 month, 36 month, and sociodemographic and treatment history were collected from medical records. We conducted height, weight, waist circumference, blood pressure, FBS, total cholesterol, HDL, triglyceride, and QTc interval. Metabolic syndrome was diagnosed by ATPIIIa criteria. RESULTS: Aripiprazole showed the significant difference in the impact on weight, blood pressure, waist circumference, total cholesterol, HDL, triglyceride than paliperidone and olanzapine at 1-year and 3-year period. Olanzapine showed the significant increase of weight and triglyceride than paliperidone at 3-year period. The prevalence of metabolic syndrome increased in paliperidone at 1-year and in olanzapine at 3-year period compared to aripiprazole significantly. CONCLUSION: We concluded that aripiprazole has less impact on the abdominal obesity, FBS, blood pressure, and cholesterol than paliperidone and olanzapine. Olanzapine showed the increase of long-term metabolic risk than other agents. There was needed the routine screening and multidisciplinary management of medical problems in schizophrenic patients for the prevention of metabolic syndrome.

Neutropenia with Multiple Antipsychotics Including Dose Dependent Neutropenia with Lurasidone

Antipsychotic-induced agranulocytosis is a significant side effect that is known to occur with most of the antipsychotic medications.
