Title: Tardive Dyskinesia with Atypical Antipsychotic Drugs. VOLUME: 2 ISSUE: 3. Author(s):Jambur Ananth, Kartik Ananth and Aparna Keshavan. Affiliation:Metropolitan State Hospital,11401 Bloomfield Avenue, Norwalk 90650, USA.. Keywords:Tardive dyskinesia, clinical features of tardive dyskinesia, pathophysiology of tardive dyskinesia, epidemiology of tardive dyskinesia, risk factors for tardive dyskinesia, tardive dykinesia with atypical antipsychotic agents. Abstract: Tardive dyskinesia (TD) manifests as abnormal involuntary movements that develop gradually in patients receiving antipsychotic medication. The clinical characteristics are a) the movements disappear from the group of muscles engaged in a voluntary activity, b) they can be voluntarily suppressed for a few seconds c) during sleep they disappear and d) the most frequent site is the bucco-oral area. Movements indistinguishable from those of TD can also occur in several neurological disorders as well as in patients receiving phenytoin ...

Pimozide is a high potency antipsychotic medication which has been used in many countries since the 1970s for the treatment of schizophrenia and other psychoses. In the US, it was licensed in the past decade as an orphan drug for the treatment of Tourettes syndrome.. Sultana and McMonagle have identified randomised controlled trials of pimozide for the treatment of schizophrenia. Not surprisingly, pimozide was found to be more effective than placebo for preventing relapse and was similar to other typical antipsychotic drugs in efficacy and side effect profile.. Several unanswered questions remain. It has been claimed that pimozide is more effective than other typical antipsychotic drugs for treating negative symptoms of schizophrenia.1 None of the studies included in the review specifically reported on negative symptoms as an outcome, so the review was unable to support or refute this claim. In addition, the efficacy of pimozide relative to the newer atypical antipsychotic drugs is unknown ...

TY - JOUR. T1 - Critical review of antipsychotic polypharmacy in the treatment of schizophrenia. AU - Fleischhacker, W. Wolfgang. AU - Uchida, Hiroyuki. PY - 2014. Y1 - 2014. N2 - Antipsychotic polypharmacy remains prevalent; it has probably increased for the treatment of schizophrenia in real-world clinical settings. The current evidence suggests some clinical benefits of antipsychotic polypharmacy, such as better symptom control with clozapine plus another antipsychotic, and a reversal of metabolic side-effects with a concomitant use of aripiprazole. On the other hand, the interpretation of findings in the literature should be made conservatively in light of the paucity of good studies and potentially serious side-effects. Also, although the available data are still limited, two smaller-scale clinical trials provide preliminary evidence that converting antipsychotic polypharmacy to monotherapy could be a valid and reasonable treatment option. Several studies have explored strategies to change ...

This study aimed to assess the neurophysiological effects of acute atypical antipsychotic treatment on cognitive functioning in subjects presenting with a first episode of psychosis. We used functional MRI to examine the modulatory effects of acute psychopharmacological intervention on brain activation during four different cognitive tasks: overt verbal fluency, random movement generation, n-back and a spatial object memory task. Treatment with atypical antipsychotics was associated with alterations in regional activation during each task and also when task demands were manipulated within paradigms. The initial treatment of psychosis with atypical antipsychotics thus appears to be associated with modifications of the neurofunctional correlates of executive and mnemonic functions. These effects need to be considered when interpreting group differences in activation between medicated patients and controls.

DESCRIPTION (provided by applicant): Clinical work on the mother-child relationship shows that the quality of maternal care from women with schizophrenia is generally inferior to that from healthy mothers. One important contributing factor recognized by both patients and their clinicians is antipsychotic medications. Both typical and atypical antipsychotics are reported to adversely affect maternal care. The PIs long-term goal is to understand the neurobiological and behavioral mechanisms of action of antipsychotic drugs. The objective of this R03 application is to determine the behavioral and neurochemical mechanisms underlying the adverse effects of both typical and atypical antipsychotics on maternal behavior using a rat model. The project hypothesis is that at the clinical relevant dose, the disruptive effect of antipsychotics on maternal behavior primarily reflects a suppressive effect on maternal motivation and is mediated via the dopamine D2 receptor system. Rat maternal behavior is ...

BACKGROUND: Recent literature documents a stronger association between nonfasting triglycerides (TG) and cardiovascular risk compared to fasting TG. Given concerns over antipsychotic effects on serum TG, this analysis explored changes in nonfasting TG in phase 1 of the CATIE Schizophrenia Trial.METHODS: Change in nonfasting TG, adjusted for baseline value, was compared between

Second generation antipsychotic drugs (SGAs) cause substantial body weight gain/obesity and other metabolic side-effects such as dyslipidaemia. Their antagonistic affinity to the histaminergic H1 receptor (H1R) has been identified as one of the main contributors to weight gain/obesity side-effects. The effects and mechanisms of betahistine (a histaminergic H1R agonist and H3 receptor antagonist) have been investigated for ameliorating SGA-induced weight gain/obesity in both animal models and clinical trials. It has been demonstrated that co-treatment with betahistine is effective in reducing weight gain, associated with olanzapine in drug-naïve patients with schizophrenia, as well as in the animal models of both drug-naïve rats and rats with chronic, repeated exposure to olanzapine. Betahistine co-treatment can reduce food intake and increase the effect of thermogenesis in brown adipose tissue by modulating hypothalamic H1R-NPY-AMPKα (NPY: neuropeptide Y; AMPKα: AMP-activated protein kinase α)

Objective:A few case reports on the use of aripiprazole in neuroleptic-induced tardive dyskinesia have demonstrated positive effects. However its effectiveness in treatment of TD was still inconclusive. The aim of the present study was to investigate the efficacy of aripiprazole in management of pre-existing neuroleptic-induced tardive dyskinesia.. Method: Subjects with pre-existing neuroleptic-induced tardive dyskinesia were chosen from Taoyuan psychiatric center. Patients recruited would be treated with aripiprazole for cross-titration with previous antipsychotics in 8 weeks. We use AIMS, SAS, & BAS to assess the severity of TF and EPS. We record subjects age, sex, and other factors which have influence at the treatment response. Subjects are assessed every two weeks in the first month and then monthly until six months. ...

Antipsychotics are the most important treatment for schizophrenia. However, antipsychotics, particularly olanzapine and clozapine, are associated with severe weight gain/obesity side-effects. Although numerous studies have been carried out to identify the exact mechanisms of antipsychotic-induced weight gain, it is still important to consider other pathways. Endoplasmic reticulum (ER) stress signaling and its associated inflammation pathway is one of the most important pathways involved in regulation of energy balance. In the present study, we examined the role of hypothalamic protein kinase R like endoplasmic reticulum kinase- eukaryotic initiation factor 2α (PERK-eIF2α) signaling and the inflammatory IkappaB kinase β- nuclear factor kappa B (IKKβ-NFκB) signaling pathway in olanzapine-induced weight gain in female rats. In this study, we found that olanzapine significantly activated PERK-eIF2α and IKKβ-NFκB signaling in SH-SY5Y cells in a dose-dependent manner. Olanzapine treatment for ...

There is no standard treatment for tardive dyskinesia. Most interventions focus on adjusting the medication thought to be causing tardive dyskinesia. In many cases neuroleptic medications will be adjusted to use the lowest possible dose, or discontinued if at all possible. Stopping the medication is a gradual process, lowering the doses 10 to 25 percent every one to three months. Replacing the neuroleptic drug with other medications may help some patients. Other drugs such as tranquilizers like benzodiazepines and medicines that mimic the effect of dopamine, may also be beneficial. Symptoms of tardive dyskinesia may remain even after the medication is stopped. However, with careful management, some symptoms may improve or disappear with time.. Tardive dyskinesia symptoms may take time to develop. On some occasions symptoms do not arise until after neuroleptic drug use has been stopped. For this reason, tardive dyskinesia may be hard to diagnose. If you think you have tardive dyskinesia seek ...

OBJECTIVE: The Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) study examined the comparative effectiveness of antipsychotic treatments for individuals with chronic schizophrenia. Patients who had discontinued antipsychotic treatment in phases 1 and 2 were eligible for phase 3, in which they selected one of nine antipsychotic regimens with the help of their

The clinical picture and features of NMS with atypical antipsychotics seem to be different from those of typical antipsychotics. This had led to uncertainty over the diagnosis of NMS in patients on atypical antipsychotics who manifest only few of the NMS symptoms.38 Among the core symptoms of NMS, fever is often encountered less frequently in patients with atypical antipsychotic-induced NMS.38 The issue is further complicated by the various operational definitions of NMS.38 The DSM-IV-TR defines NMS as the presence of severe muscle rigidity and elevated temperature after antipsychotic initiation along with two or more of: diaphoresis, dysphagia, tremor, incontinence, changes in level of consciousness, mutism, tachycardia, elevated or labile blood pressure, leukocytosis, or laboratory evidence of muscle injury (elevated CPK level). Various other criteria for NMS have been postulated, each with varying emphasis on the individual symptoms and signs.39 Another set of criteria defines NMS in patients ...

Sarasota, FL - (PRESS RELEASE JET) - 10/20/2017 - Global Tardive Dyskinesia (TD) Treatment Market: Overview. Tardive dyskinesia (TD) is a neurological disorder that has the involvement of the involuntary movements. The terms can be described as tardive which means delayed and dyskinesia which means abnormal movement. The symptoms of tardive dyskinesia include finger movement, facial grimacing, jaw swinging, repetitive chewing, continuous blinking of the eyes, tongue thrusting, and others. The side effect of the neuroleptics medicines is tardive dyskinesia. These medicines are also known as major tranquilizers or antipsychotics. These medicines are mainly used for treating mental issues. Tardive dyskinesia occurs when you are on the medication for many months or years. As the drug that can be used for the treatment of tardive dyskinesia is not approved and method of treatment is also yet not confirmed thus the treatment of the disease is a difficult task. The tardive dyskinesia treatment affects ...

As is the case with many chronic illnesses, it can be challenging for people with schizophrenia to take multiple pills every day on a long-term basis. At the same time, missing or discontinuing the anti-psychotic medications that treat schizophrenia substantially increases the risk of relapse and re-hospitalization. This study will determine how effective long-acting injectable risperidone is compared to oral antipsychotic medications to help patients who have schizophrenia. Patients who enroll in the study will be randomly assigned to receive either long-acting injectable risperidone or to receive oral atypical antipsychotic medication. The atypical antipsychotics that are included for patients in the oral group are: aripiprazole, olanzapine, quetiapine, risperidone, and ziprasidone. Patients in the oral group will receive whichever of the five atypical antipsychotic medications they and their study doctor decide is best for them. Patients in the oral group will be allowed to switch ...

The present study evaluated the receptor binding affinities, functional activities, and behavioral pharmacological characteristics of lurasidone in various animal models. The current results demonstrate that lurasidone possesses potent antipsychotic-, anxiolytic-like, and antidepressant-like activity with a low propensity for EPS, motor impairment, and CNS depressant side effects.. In vitro receptor binding experiments in the present study have shown Ki values in typical and atypical antipsychotics, which were comparable with those in previous reports (e.g., Kroeze et al., 2003). The present study reveals that lurasidone has potent affinity for dopamine D2 and 5-HT2A receptors; however, unlike most second-generation antipsychotics, it completely lacks binding affinity for histamine H1 and muscarinic receptors. Olanzapine, risperidone, and clozapine have higher affinity for the histamine H1 receptor, and olanzapine and clozapine have significant binding affinity for the muscarinic receptor. ...

Neurocognitive impairment in schizophrenia is severe and is an important predictor of functional outcome. The relative effect of the second-generation (atypical) antipsychotic drugs and older agents on neurocognition has not been comprehensively determined. Keefe RSE, Bilder RM, Davis SM, Harvey PD, Palmer BW, Gold JM, Meltzer HY, Green MF, Capuano G, Stroup TS, McEvoy JP, Swartz MS, Rosenheck RA, Perkins DO, Davis CE, Hsiao JK, and Lieberman JA for the CATIE Investigators and the Neurocognitive Working Group.

The use of antipsychotic agents can be limited by side effects, particularly extrapyramidal symptoms (EPS) and tardive dyskinesia (TD). These neurologic movement disorders can occur early in the course of treatment (often as EPS) or as a more latent effect (TD). TD can be debilitating, and several patient-related and treatment-related factors have been associated with an increased risk for its development. Of these, older age has been strongly linked to TD. The advent of novel antipsychotics for the treatment of schizophrenia and severe behavioral disorders permits the use of such agents with reduced risk of EPS and TD. Most clinical trials of the novel antipsychotics have enrolled younger patients, but some data on their efficacy and safety in the elderly are now available. This article reviews the relationship between TD and aging and its treatment in elderly patients. ...

Extrapyramidal Side Effects Antipsychotic-induced EPS may occur acutely or after long-term treatment. First-generation antipsychotics, in particular high-potency neuroleptics, are more likely than second-generation antipsychotics to cause EPS when the drugs are used at usual therapeutic doses. However, as can be noted in Table Selected side effects of commonly used antipsychotic medications, considerable variation in the… Read More ». ...

Although antipsychotics currently used in the clinic are generally effective against the positive symptoms of schizophrenia there is still a need to design novel antipsychotics that would be efficacious against the positive and negative symptoms, lack the adverse side effects of current therapy (extrapyramidal motor symptoms, hyperprolactinaemia, agranulocytosis, seizures) and be effective in treatment-resistant patients. Approaches so far in this area have been primarily directed at mimicking the atypical antipsychotic clozapine. The superior clinical profile of clozapine (greater efficacy than typical antipsychotics against positive and possibly negative symptoms of schizophrenia, effective in some refractory patients and causing fewer EPS) has been difficult to pinpoint to a single pharmacological action because clozapine binds with high affinity to many neurotransmitter receptors (Fitton and Heel, 1990; Baldessarini and Frankenburg, 1991). The identification of the dopamine D4 receptor ...

The serotonin (5-HT) 1A receptor has been found to be dysregulated in prefrontal cortex and other brain regions in schizophrenia, and 5-HT1A receptor levels in the amygdala have been related to negative schizophrenia symptoms. We have assessed the impact of the functional C-1019G variant of the 5-HT1A receptor on the response to risperidone or haloperidol in a prospective, randomized, double-blind study. Patients were treated for 4 weeks and negative symptoms assessed weekly. The variant influenced the response to risperidone: improvement of negative symptoms by 4.38 points for carriers of the C allele, compared with the GG genotype (1.22 points, P=0.046). In a second independent study of 130 schizophrenia patients treated with atypical antipsychotics, this effect was confirmed (P=0.003). The functional variant of the 5-HT1A receptor thus influences the response of schizophrenia patients to atypical antipsychotics and may be useful in the future to predict the pharmacogenetics of negative ...

The NICE guideline issued in 2002 recommended that the second-generation, so-called atypical antipsychotics, should be used as first-line treatments mainly due to a reduced incidence of extrapyramidal side-effects.[4] The revised guidance, however, does not recommend a particular medicine, or class of medication, but highlights the role of patient choice; it recommends that the choice of medicine should be a joint decision between the service user and healthcare professional.[3]. The decision should consider the adverse event profile, particularly in respect to extrapyramidal and metabolic adverse events, and if appropriate involve the carer.[3]. The new guidelines have been heavily influenced by two major new studies; CATIE and CUTLASS.[5],[6] In CATIE 1,493 people with chronic schizophrenia from 57 sites in the USA, were randomised to the typical anti-psychotic, perphenazine, or one out of four atypicals (olanzapine, quetiapine, risperidone or ziprasidone, which is not available in the ...

While the recent publication of Phase I results of the landmark Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) study enabled pharmaceutical companies and stock pundits to declare winners and losers among the marketed antipsychotics, the big winners may be clinicians who treat the 3.2 million Americans suffering from schizophrenia. The results of the CATIE study provide the most comprehensive set of data on the pharmacologic treatment of schizophrenia ever assembled, Jeffrey A. Lieberman, M.D., a Columbia University psychiatrist and lead author of the study, said at a press conference. These [results] will guide doctors in their selection of treatments and clinical management of individual patients. This is because no study has ever examined all marketed drugs in a controlled fashion for such a long time period using such extensive measures of safety and efficacy, much less the cost data..

JL13 [5-(4-methylpiperazin-1-yl)-8-chloro-pyrido[2,3-b][1,5] benzoxazepine fumarate] is a substance with a close structural resemblance to clozapine. However, it is less sensitive to oxidation and may therefore have less hematological side effects. In the present study, JL13 was compared with clozapine and haloperidol in several animal models for schizophrenia. The paw test represents a screening model for antipsychotic drugs that can discriminate between drugs with extrapyramidal side effects and drugs without. Haloperidol increased both forelimb retraction time and hindlimb retraction time (HRT), whereas both clozapine and JL13 increased only HRT. In the prepulse inhibition paradigm, all three drugs reversed the apomorphine- and the amphetamine-induced disruption of prepulse inhibition. However, whereas haloperidol was equally effective against both dopaminergic drugs, JL13 and clozapine were more effective against amphetamine. Finally, only JL13 was able to increase prepulse inhibition in ...

Atypical antipsychotics are highly effective antischizophrenic medications but their clinical utility is limited by adverse metabolic sequelae. We investigated whether upregulation of macrophage migration inhibitory factor (MIF) underlies the insulin resistance that develops during treatment with the most commonly prescribed atypical antipsychotic, olanzapine. Olanzapine monotherapy increased BMI and circulating insulin, triglyceride, and MIF concentrations in drug-naive schizophrenic patients with normal MIF expression, but not in genotypic low MIF expressers. Olanzapine administration to mice increased their food intake and hypothalamic MIF expression, which led to activation of the appetite-related AMP-activated protein kinase and Agouti-related protein pathway. Olanzapine also upregulated MIF expression in adipose tissue, which reduced lipolysis and increased lipogenic pathways. Increased plasma lipid concentrations were associated with abnormal fat deposition in liver and skeletal muscle, ...

There is excess amenable mortality risk and evidence of healthcare quality deficits for persons with serious mental illness (SMI). We sought to identify sociodemographic and clinical characteristics associated with variations in two 2015 Healthcare Effectiveness Data and Information Set (HEDIS) measures, antipsychotic medication adherence and preventive diabetes screening, among Medicaid enrollees with serious mental illness (SMI). We retrospectively analyzed claims data from September 2014 to December 2015 from enrollees in a Medicaid specialty health plan in Florida. All plan enrollees had SMI; analyses included continuously enrolled adults with antipsychotic medication prescriptions and schizophrenia or bipolar disorder. Associations were identified using mixed effects logistic regression models. Data for 5502 enrollees were analyzed. Substance use disorders, depression, and having both schizophrenia and bipolar disorder diagnoses were associated with both HEDIS measures but the direction of the

Extrapyramidal side effects are symptoms that can occur if you're taking antipsychotic medications. Here's what they include and how they're treated.

Previous studies have reported that context can powerfully modulate the inhibitory effect of an antipsychotic drug on phencyclidine (PCP)-induced hyperlocomotion (a behavioral test used to evaluate putative antipsychotic drugs). The present study investigated the experimental conditions under which environmental stimuli exert their influence through associative conditioning processes. Experiment 1 examined the extent to which prior antipsychotic treatment in the home cages affected a drugs ability to inhibit PCP-induced hyperlocomotion in a novel motor activity test apparatus. Five days of repeated haloperidol (0.05 mg/kg, sc) and olanzapine (2.0 mg/kg, sc) treatment in the home cages still potentiated their inhibition of PCP-induced hyperlocomotion (i.e. sensitization) assessed in a new environment, whereas the clozapine (10.0 mg/kg, sc) treatment enhanced the development of clozapine tolerance, indicating a lack of environmental modulation of antipsychotic efficacy. Experiment 2 assessed the impact

Increased activity within known reward-processing neurocircuitry (eg, ventral striatum, VS) has been reported among medicated individuals with bipolar disorder (BD) I and II. However, such findings are confounded by the potential ameliorative effects of mood-stabilizing and antipsychotic medications on neural activations. This study tests the hypothesis that a pathophysiological locus of alterations in reward processing is present within the striatum in antipsychotic and lithium-naive individuals with BD. Twenty antipsychotic and lithium-naive individuals with BD II or BD not-otherwise specified (NOS) and 20 matched healthy comparison individuals participated in functional magnetic resonance imaging during the performance of a monetary incentive delay task. Between-group comparisons were conducted using small-volume correction focusing on orthogonal a priori regions of interest centered in the VS and dorsal striatum (DS), respectively. During reward anticipation, unmedicated individuals with BD II/NOS

OBJECTIVE: The efficacy and safety of olanzapine were compared with those of ziprasidone.. METHOD: This was a multicenter randomized, double-blind, parallel-group, 28-week study of patients with schizophrenia. Patients were randomly assigned to treatment with 10-20 mg/day of olanzapine or 80-160 mg/day of ziprasidone. The primary efficacy measure was the Positive and Negative Syndrome Scale total score. Secondary efficacy and safety measures included Positive and Negative Syndrome Scale subscales as well as mood, quality of life, and extrapyramidal symptom scales. Safety was evaluated by recording treatment-emergent adverse events and measuring vital signs and weight.. RESULTS: The study was completed by significantly more olanzapine-treated patients (165 of 277, 59.6%) than ziprasidone-treated patients (115 of 271, 42.4%). At 28 weeks, the olanzapine-treated patients showed significantly more improvement than the ziprasidone-treated patients on the Positive and Negative Syndrome Scale overall ...

Abstract: Metabolic Syndrome is a cluster of risk factors that raise an individuals risk for developing diabetes, heart disease, stroke, and other health problems. These risk factors include: low HDL cholesterol, high blood pressure, high fasting blood glucose, high triglycerides, high BMI, and a large waistline. Metabolic Syndrome has become a more prominent topic in child and adolescent psychiatry with the increase in the prescription of antipsychotic drugs. Numerous studies have found the differential prevalence of metabolic syndrome associated with atypical antipsychotic drugs. In fact, atypical antipsychotics carry an FDA warning about metabolic risk. Specifically, there have been higher effects noted for antipsychotic medication on triglycerides, glucose, weight, and waist circumference. Many insurance companies now require monitoring for Metabolic Syndrome by psychiatric prescribers be performed and documented in the medical record. Additionally, it has been estimated that 80% of ...

The study of brain networks, including those derived from functional neuroimaging data, attracts a broad interest and represents a rapidly growing interdisciplinary field. Comparing networks of healthy volunteers with those of patients can potentially offer new, quantitative diagnostic methods and a framework for better understanding brain and mind disorders. We explore resting state functional Magnetic Resonance Imaging (fMRI) data through network measures. We construct networks representing 15 healthy individuals and 12 schizophrenia patients (males and females), all of whom are administered three drug treatments: i) a placebo; and two antipsychotic medications ii) aripiprazole and iii) sulpiride. We compare these resting state networks to a performance at an

Adding atypical antipsychotics to antidepressant treatment is the most thoroughly studied augmentation approach in MDD.37 A meta-analysis by Nelson et al37 found that atypical antipsychotics used in conjunction with antidepressants were significantly more effective in reducing depressive symptoms than placebo (P , .00001). However, some of the possible disadvantages of atypical antipsychotics are weight gain, metabolic decompensation, sedation, and extrapyramidal side effects, making tolerability of these treatments a concern. Monitoring side effects closely can improve outcomes with these treatments.. More recently, the psychostimulant lisdexamfetamine has been shown to be an effective adjunctive therapy. In a multicenter trial of 173 adults with residual depressive symptoms after 8 weeks of escitalopram treatment, Trivedi et al38 found that nonremitted patients treated with adjunctive lisdexamfetamine for 6 weeks were significantly improved according to Montgomery-Asberg Depression Rating ...

The drug: Although the exact mechanism of action of risperidone is unknown, the drug blocks receptors in the dopaminergic, adrenergic and histaminergic neurotransmitter systems as well as those in the serotonin system that may play a role in agression.7,8,9 Like other atypical antipsychotic agents, risperidone is a popular first-line agent for psychotic disorders because it is effective (especially for negative symptoms) and is associated with fewer extrapyramidal adverse effects than are traditional antipsychotic drugs.7 Risperidone, at doses higher than those used in dementia, appears to cause diabetes, worsened lipid profiles and obesity in some patients,10 but any relation between these adverse effects and risperidone-associated cerebrovascular adverse events is unclear. Risperidone should be used with caution in patients with seizure disorders and avoided in states of dehydration and hypotension.. What to do: Dementia is a difficult burden for patients and caregivers,11 but the degree to ...

Thioridazine (Mellaril or Melleril) is a piperidine typical antipsychotic drug belonging to the phenothiazine drug group and was previously widely used in the treatment of schizophrenia and psychosis. The branded product was withdrawn worldwide in 2005 because it caused severe cardiac arrhythmias. However, generic versions are still available in the US. Thioridazine was voluntarily discontinued by its manufacturer, Novartis, worldwide because it caused severe cardiac arrhythmias. Its primary use in medicine was the treatment of schizophrenia. It was also tried with some success as a treatment for various psychiatric symptoms seen in people with dementia, but chronic use of thioridazine and other anti-psychotics in people with dementia is not recommended. For further information see: Phenothiazine Thioridazine prolongs the QTc interval in a dose-dependent manner. It produces significantly less extrapyramidal side effects than most first-generation antipsychotics. Its use, along with the use of ...

TY - JOUR. T1 - An association between autumn birth and clozapine treatment in patients with schizophrenia: A population-based analysis. AU - Sørensen, Holger Jelling. AU - Foldager, Leslie. AU - Røge, Rasmus. AU - Pristed, Sofie Gry. AU - Andreasen, Jesper T.. AU - Nielsen, Jimmi. PY - 2014. Y1 - 2014. N2 - Background: Numerous studies on seasonality of birth and schizophrenia risk have been published but it is uncertain whether, among those with schizophrenia, refractory illness exhibits any predilection for birth month. We hypothesized and examined whether a season of birth effect was present in patients with schizophrenia with a history of clozapine treatment. Method: Using record linkage with Danish registers, we examined patients with schizophrenia born between 1950 and 1970, and between 1995 and 2009 and Cox regression analysis was used to examine season of birth in relation to history of clozapine treatment. Results: In a study population corresponding to 60,062 person-years from 5328 ...

Schizophrenia is a mental disorder affecting approximately one percent of the population worldwide. The introduction of the second generation antipsychotic drug, atypical antipsychotic, clozapine, has demonstrated 80% reduction in suicide incident. This drug showed effectiveness in the treatment of resistant schizophrenia, however, high concentrations of clozapine and N-desmethylclozapine in plasma exhibit the development of agranulocytosis, a possible lethal blood disorder. Therefore, constant therapeutic drug monitoring is important for patients who receive clozapine. High performance liquid chromatography (HPLC) is the current assay for clinical clozapine measurement. A different assay, the capillary electrophoresis (CE) was explored in this study. It was found the use of a background electrolyte (BGE) concentration of 60 mM, pH at 2.5, temperature at 22 ℃, voltage applied at 10 kV and sample injection at 23 kV for 1.5 seconds is the optimal condition for clozapine separation using a ...

TY - JOUR. T1 - Decreased BDNF in patients with antipsychotic naïve first episode schizophrenia. AU - Jindal, Ripu D.. AU - Pillai, Anilkumar R. AU - Mahadik, Sahebrao P.. AU - Eklund, Kevin. AU - Montrose, Debra M.. AU - Keshavan, Matcheri S.. PY - 2010/6/1. Y1 - 2010/6/1. N2 - Objective: Brain-derived neurotrophic factor (BDNF) is a key factor known to mediate neuronal proliferation, differentiation, survival and response to stress. Decreases in BDNF levels have been reported in schizophrenia, but studies in treatment naïve patients are few. Herein we report on serum BDNF levels in a series of patients with first-episode treatment naïve psychoses in comparison to age matched healthy controls. Method: Fasting serum BDNF levels were measured in 41 patients with treatment naive first episode psychosis (24 with schizophrenia, schizoaffective disorder or schizophreniform disorder, and 17 with non-schizophrenia psychotic disorders) and 41 age-matched healthy controls. Results: A three group ...

Objective: To evaluate the prevalence and severity of hyperprolactinemia among a large sample of patients with schizophrenia and related psychotic disorders treated with typical and atypical antipsychotic medications. Method: Three electronic databases (general medical, psychiatric, and pharmacologic) containing the census data from November 2002 through March 2003 for a state-funded, inpatient hospital serving the chronically mentally ill were merged (N = 470). This database was purged of patient names, while the unique hospital identification number and demographic variables in each record were retained. These records were then screened to exclude patients with medications (except neuroleptics) or medical conditions known to elevate or suppress prolactin, leaving an overall sample (N = 422) in which to evaluate the prevalence of hyperprolactinemia. The sample was composed of patients with DSM-IV schizophrenia (N = 213), other related psychotic disorders (N = 131), mood disorders (N = 44), and ...

Asenapine monotherapy in the acute treatment of both schizophrenia and bipolar I disorder Delia Bishara1, David Taylor1,21Pharmacy Department, South London and Maudsley NHS Foundation Trust, Denmark Hill, London, UK; 2Division of Pharmaceutical Sciences, King’s College, London, UKAbstract: Asenapine is a new atypical antipsychotic agent currently under development for the treatment of schizophrenia and bipolar disorder. It has high affinity for various receptors including antagonism at 5HT2A, 5HT2B, 5HT2C, 5HT6 and 5HT7 serotonergic receptor subtypes, α1A, α2A, α2B and α2C adrenergic and D3 and D4 dopaminergic receptors. As with other atypicals, asenapine exhibits a high 5HT2A:D2 affinity ratio. Although similar to clozapine in its multitarget profile, it shows no appreciable affinity for muscarinic receptors. Asenapine has shown efficacy in alleviating both positive and negative symptoms of schizophrenia compared with placebo. Although promising, further studies are

TY - JOUR. T1 - Rapid-acting IM ziprasidone in a psychiatric emergency service. T2 - A naturalistic study. AU - Preval, Horacio. AU - Klotz, Steven G.. AU - Southard, Robert. AU - Francis, Andrew. PY - 2005. Y1 - 2005. N2 - Atypical antipsychotics have gained acceptance as first-line treatment for psychotic disorders. Rapid-acting intramuscular (IM) atypicals may supplant benzodiazepine and/or neuroleptic alternatives. IM atypical ziprasidone studies excluded severe psychiatric agitation (PSYCH), or that due to the abuse of alcohol (ETOH) or other substances (SUBS). We report Behavioral Activity Rating Scale agitation scores (range, 1-7) and duration of physical restraints in a naturalistic study in a psychiatric emergency service using IM ziprasidone 20 mg and various doses for conventional antipsychotics. Baseline scores were high for PSYCH, ETOH and SUBS patients (mean, 6.5, 6.9 and 6.6, respectively). Agitation decreased rapidly from baseline with ziprasidone [mean, 5.6, 5.3 and 5.8, ...

EPS encompass several acute/reversible (akathisia and dystonia) and chronic/irreversible (tardive dyskinesia and focal perioral tremor) side effects of psychoactive medications. They are believed to be caused by a blockade of dopamine receptors (D2) or depletion of dopamine in the basal ganglia. Older (typical or first generation antipsychotics) have a higher propensity for producing EPS because of strong binding to dopamine receptors (D2). Newer (atypical, or second-generation antipsychotics) have a lower risk of EPS, in part due to blockage of serotonin receptors. Continued untreated akathisia is a risk factor for developing chronic akathisia ...

Diagnosing tardive dyskinesia early is very important. Sometimes, if the drug that is causing TD is stopped early enough, the tardive dyskinesia will go away. This is more likely to happen if the TD is diagnosed soon after its symptoms start.[3] Sometimes, even if the medication is stopped, the tardive dyskinesia never goes away.[1] If a person with TD still needs antipsychotic medicines, a medication called clozapine (Clozaril) is the best choice. It is a newer antipsychotic, it often works well for schizophrenia that is hard to treat, and it has less of a risk of causing or worsening TD.[2] The United States Food and Drug Administration (FDA) has not approved any medicines to treat the symptoms of tardive dyskinesia. Some doctors use these medications:[2] ...

TY - JOUR. T1 - Changes in weight and body mass index during treatment with melperone, clozapine and typical neuroleptics. AU - Bobo, William V.. AU - Jayathilake, Karuna. AU - Lee, Myung A.. AU - Meltzer, Herbert Y.. PY - 2010/4/1. Y1 - 2010/4/1. N2 - Melperone is an atypical antipsychotic drug that has been reported to be effective in treatment-resistant schizophrenia and L-DOPA psychosis. There are limited data concerning its effect on weight or body mass index (BMI). Weight and BMI were retrospectively compared in patients with schizophrenia treated with melperone (n=34), clozapine (n=225), or typical neuroleptics (n=74) for up to 3 months. Clozapine resulted in significant increases in weight and BMI from baseline to 6 weeks and 3 months. Neither melperone nor typical neuroleptics resulted in significant weight gain at either time point. Melperone did not result in significant increases in BMI. Weight and BMI were significantly lower with melperone compared with clozapine, but similar to ...

It is commonly thought that symptoms of schizophrenia arise as a consequence of increased dopamine transmission and that antipsychotic drugs alleviate symptoms by blocking this activity. The study team used D-amphetamine (a drug that can induce psychotic symptoms in humans) to model psychotic symptoms seen in schizophrenia in an animal model. D-amphetamine increases dopamine release disrupting the mouses ability to ignore relevant stimuli in the environment. This effect is reversed by administering antipsychotic drugs.. The research team was surprised to see the same behavioural effect in mice with D2 receptors genetically deleted. Their discovery suggests that this model could be used to identify new non-D2 drug targets that could influence the symptoms of schizophrenia without the side-effects that are seen in current drug treatments.. The research was led by Dr Paula Moran, an expert in psychopharmacology. She said: Our study shows the very surprising finding that antipsychotic drugs ...

Risperidone is an antipsychotic drug. In blood, this drug binds mainly to human serum albumin (HSA) and is also transported by HSA. Methods: To study certain details of the interaction between risperidone and HSA, a fluorescent dye CAPIDAN was used as a reporter. This dye specifically fluoresces from HSA in serum and is highly sensitive to structural changes in HSA including pathology-induced changes. Interaction of CAPIDAN with HSA has been studied using time-resolved fluorescence techniques. Results: The addition of phenylbutazone, a marker for the HSA drug-binding site I, leads to displacement of CAPIDAN from this site due to direct competition between phenylbutazone and the dye. The addition of risperidone induces a response of CAPIDAN fluorescence that is highly similar to its response to phenylbutazone.. ...

TY - JOUR. T1 - Efficacy of risperidone on positive features of schizophrenia. AU - McEvoy, Joseph Patrick. PY - 1994/6/20. Y1 - 1994/6/20. N2 - Dopaminergic hyperactivity mediated via D2 receptors is implicated in the etiology of positive symptoms of schizophrenia, but selective D2 antagonists provide imperfect therapy. This article describes a subanalysis of a trial of risperidone, a combined 5-HT(2A)/D2 antagonist, in 513 patients with DSM- III-R chronic schizophrenia. Risperidone at 2, 6, 10, and 16 mg/day was compared with placebo and haloperidol 20 mg/day. All doses of risperidone and the 20-mg dose of haloperidol were superior to placebo (mean change from baseline on the PANSS positive and general psychopathology subscales). The 6- mg dose of risperidone also produced significantly more improvement than haloperidol 20 mg. We conclude that risperidone is an effective drug for patients with positive features of schizophrenia.. AB - Dopaminergic hyperactivity mediated via D2 receptors is ...

TY - JOUR. T1 - A longitudinal study of correlations among tardive dyskinesia, drug- induced parkinsonism, and psychosis. AU - Hansen, Thomas. AU - Weigel, R. M.. AU - Brown, W. L.. AU - Hoffman, W. F.. AU - Casey, Daniel. PY - 1992. Y1 - 1992. N2 - Tardive dyskinesia (TD) and drug-induced parkinsonism (DIP) have been hypothesized to reflect opposing states of dopamine (DA) function. In this longitudinal study, 57 psychotic inpatients were rated repeatedly for TD, DIP, and psychosis while receiving neuroleptic medication. Cross-sectional correlations among TD, DIP, and psychosis were weak or nonexistent. Factor and cluster analyses found that 13 patients (23%) were classified into groups characterized by the expected negative correlations. Thus, only partial support was found for the hypothesis that TD and DIP represent opposing states of DA function.. AB - Tardive dyskinesia (TD) and drug-induced parkinsonism (DIP) have been hypothesized to reflect opposing states of dopamine (DA) function. In ...

Schizophrenia treatment varies by individual but typically consists of medications and psychosocial treatments, like therapy. The International Psychopharmacology Algorithm Project suggests that the pharmacologic treatment for the prodromal stages of schizophrenia has not been sufficiently well studied, and in the absence of adequate evidence, the recommended approach is symptomatic treatment of prodromal symptoms. Schizophrenia requires long-term treatment, and patients are advised to continue their treatment even when they become free of their symptoms so that they can avoid a relapse. For example, described herein are methods of treating a developmentally-based neuropsychiatric disorder (schizophrenia) that includes first determining if a subject is at risk for such … The treatment team also may include a psychologist, social worker, psychiatric nurse and possibly a case manager to coordinate care. Prior to the development of the full-blown disorder, people who go on to develop ...

The dopamine hypothesis of schizophrenia states that the illness is due to overactivity of dopamine mechanisms in the brain. This hypothesis is based on two facts: (1) drugs, such as amphetamine, that enhance dopaminergic neurotransmission in the brain, may occasionally provoke a schizophrenic psychosis; and (2) acute administration of neuroleptic drugs, which are used to treat schizophrenia and other psychotic illnesses, causes blockade of brain dopamine receptors and initiates a chain of compensatory events which attempt to overcome such an action. We have previously shown that administration of neuroleptic drugs to rats for up to 18 months produces unexpected effects1,2: after 6 months, all signs of blockade of dopamine receptors in the striatum have disappeared, and thereafter striatal dopamine receptors increase in number and become behaviourally supersensitive to administered dopamine agonists such as apomorphine. We now show that such chronic exposure to neuroleptics completely alters ...

Dystonia is one of the most common types of tardive dyskinesia.. Tardive dyskinesia (TD) is any involuntary, purposeless movement of the tongue, lips, face, trunk, and extremities that occur mainly in patients treated with long-term neuroleptic drugs which are prescribed for psychiatric disorders and certain gastrointestinal and neurological disorders.. TDs may present as grimacing, tongue protrusion, lip-smacking, puckering, and rapid eye blinking. Rapid movements of the arms, legs, and trunk and involuntary finger movements sometimes occur.. TDs are seen in many patients with schizophrenia, schizoaffective disorder or bipolar disorder who have received treatment with antipsychotic medication for long periods. From time to time, TDs strike other patients as well.. People with fetal alcohol syndrome, other developmental disabilities, and other brain disorders are at high risk for the development of TDs, which can begin after taking only one dose of the causative agent.. It is estimated that TDs ...

The aim of the study was to investigate the effect of switching to aripiprazole on sexual dysfunction and the hypothalamic-pituitary- gonadal axis in male patients with schizophrenia. In this prospective, open-label study, the participants were 10 male schizophrenia patients treated with atypical antipsychotics, risperidone, amisulpride, and olanzapine. Before and after switching to aripiprazole, they were assessed on the Arizona Sexual Experience Scale, and hormonal levels were measured. Our results showed a significant improvement in the severity of sexual dysfunction, especially ...

Background Despite frequent use, little is known about the metabolic and endocrine side-effects of antipsychotics in individuals with intellectual disability. Aims To compare indices of obesity, glucose, lipids and prolactin between antipsychotic-treated and antipsychotic-naive individuals with intellectual disability and also between participants with intellectual disability and controls from the general population. Method Observational study comparing 138 antipsychotic-treated and 64 antipsychotic-naive participants with intellectual disability in one National Health Service trust with general population controls. Results Antipsychotic treatment comprised: risperidone 48%, olanzapine 18%, thioxanthenes 10%, other 24%; monotherapy 95% of participants; mean treatment duration 8 years; median daily chlorpromazine equivalent dose 108 mg (range 16-667). Metabolic indices were the same or more favourable in the intellectual disability group than the general population control group but ...

Attention-deficit hyperactivity disorder (ADHD) is more common in people with intellectual disability than in the general population. As in the general population, ADHD adversely affects the ability to learn and is associated with behavioural disturbance, and therefore any intervention to reduce these symptoms is important.. Risperidone is a newer atypical antipsychotic medication, prescribed to people with ID for many reasons, including disruptive behaviour, ADHD and psychosis. Most of the research into using risperidone for hyperactivity or disruptive behaviour has been performed in people with autism who do not have a clear diagnosis of ADHD. The aim of this review was to examine the effectiveness of risperidone in people (children and adults) with intellectual disability and ADHD.. No trials were found, and therefore there is no randomised controlled trial evidence to support or warn against the use of risperidone in this group of people. It is important that this reseearch question is ...

Quetiapine is an atypical antipsychotic medication effective for treating schizophrenia, bipolar disorder, and major depressive disorder. A small, randomized, placebo-controlled trial found significant improvement in noncognitive aspects of delirium with quetiapine.9 Although haloperidol is the accepted standard for the treatment of delirious behavior, a study found that treatment with a low dose of quetiapine and haloperidol may be equally effective and safe for treating delirium.10. Diagnosis of DILD generally depends upon a definite temporal association between a history of drug therapy and the onset and progression of respiratory complaints. Most importantly, to ensure accurate diagnosis, other causes of lung damage, such as infectious disease, must be excluded.11,12 Laboratory findings and clinical manifestations of DILD, such as cough, fever, dyspnea, and hypoxemia, are nonspecific. There are 2 mechanisms involved in DILD that are probably interdependent: one is cytotoxic pulmonary injury, ...

Objective: To determine whether environmental temperature, agitation, neuroleptic use, mental retardation, and affective disorders were risk factors for neuroleptic malignant syndrome (NMS).. Method: Cases and age- and sex-matched psychiatric controls admitted to a regional acute psychiatric unit over a 10-year period.. Results: Both uni- and multivariate analysis revealed statistically significant differences between patients with NMS (n=15) and controls (n=45) with regard to the presence of mental retardation, psychomotor agitation, and a number of variables relating to neuroleptic use (newly introduced or increased, intramuscular administration, and dosage). We found no differences between NMS patients and psychiatric controls in respect of changes in environmental temperature.. Conclusion: Our study supports the need for caution when using intramuscularly administered, abruptly increasing, high-dose neuroleptics, particularly in mentally retarded or agitated patients, regardless of ...

BACKGROUND: The optimal pharmacological treatment of unipolar psychotic depression is uncertain. AIMS: To compare the clinical effectiveness of pharmacological treatments for patients with unipolar psychotic depression. METHOD: Systematic review and meta-analysis of randomised controlled trials. RESULTS: Ten trials were included in the review. We found no evidence that the combination of an antidepressant with an antipsychotic is more effective than an antidepressant alone. This combination was statistically more effective than an antipsychotic alone. CONCLUSIONS: Antidepressant monotherapy and adding an antipsychotic if the patient does not respond, or starting with the combination of an antidepressant and an antipsychotic, both appear to be appropriate options for patients with unipolar psychotic depression. However, clinically the balance between risks and benefits may suggest the first option should be preferred for many patients. Starting with an antipsychotic alone appears to be inadequate.

When to start aripiprazole therapy in patients with bipolar mania Kiran Kumar Sayyaparaju,1 Heinz Grunze,1 Kostas N Fountoulakis2 1Newcastle University, Institute of Neuroscience, Academic Psychiatry, Newcastle upon Tyne, UK; 23rd Department of Psychiatry, Division of Neurosciences, School of Medicine, Aristotle University of Thessaloniki, Greece Abstract: Aripiprazole is a third generation atypical antipsychotic with compelling evidence as a highly effective treatment option in the management of acute manic and mixed episodes of bipolar I disorders. It has a unique mode of action, acting as a partial agonist at dopamine D2 and D3, and serotonin 5-HT1A; and exhibiting antagonistic action at the 5-HT2A and H1 receptors. Overall, it has a favorable safety and tolerability profile, with low potential for clinically significant weight gain and metabolic effects, especially compared to other well-established treatments. It also has a superior tolerability profile when used as maintenance treatment. Side

Antipsychotic (neuroleptic) drugs induce structural alterations in synaptic terminals and changes in the expression of presynaptic protein genes. Whether there are also changes in corresponding postsynaptic (dendritic) markers has not been determined. We describe the effect of 14-day treatment with typical (haloperidol, chlorpromazine) or atypical (clozapine, olanzapine, risperidone) antipsychotics on the expression of two dendritic protein genes, microtubule-associated protein 2 (MAP2) and spinophilin, using in situ hybridization, in the rat hippocampus, retrosplenial, and occipitoparietal cortices. MAP2 mRNA was increased modestly in the dentate gyrus and retrosplenial cortex by chlorpromazine, risperidone, and olanzapine and in the occipitoparietal cortex by chlorpromazine, haloperidol, and risperidone. None of the antipsychotics affected spinophilin mRNA in any area. Overall, these results show a modulation of MAP2 gene expression, likely reflecting functional or structural changes in the dendritic

We found that the mechanism by which perphenazine was killing cancer cells was independent of its antipsychotic activity, says Gutierrez, who was a fellow in Looks laboratory and who has recently established his own lab at Dana-Farber/Boston Childrens. When we looked more closely, we found that the drug also activated a tumor-suppressing protein called PP2A.. This is unusual. In general, anticancer drug research seeks to find proteins that are active only in cancer cells and develop ways to shut them off. But perphenazine was doing the opposite: In reactivating PP2A, the drug was reactivating a protein that the tumor cells had turned off, triggering the cells to die.. In other words, perphenazine was relieving the suppression on the suppressor, thereby forcing cancer cells in the model to die.. We rarely find potential drug molecules that activate an enzyme, Gutierrez explains. But, here, perphenazine is restoring the activity of PP2A in the T-ALL cell.. Perphenazine was relieving the ...

The review by Kennedy et al provides useful information on the effectiveness of risperidone compared with conventional neuroleptics (mainly haloperidol) in patients with chronic schizophrenia. The reviewers increased the robustness of their conclusions by including only randomised controlled trials. One of the main contributions of the review is to highlight the clear limitations of the primary studies. Most of the trials studied patients for ,12 weeks and all but 1 trial randomised only patients with chronic schizophrenia and used a cut off of 20% in rating scales (BPRS and PANSS) to measure improvement. No suitable information regarding clinically meaningful outcomes such as relapse, hospitalisation, quality of life, social functioning, or employment status of the patients was provided by the original trials. The absence of cost data precluded an analysis of the cost effectiveness of risperidone. Additionally, although risperidone seems to cause fewer EPS, this medication was compared with a ...

On August 22, 2007, Risperdal was approved as the only drug agent available for treatment of schizophrenia in youth ages 13 17; it was also approved that same day for treatment of bipolar disorder in youth and children ages 10 17, joining lithium. Risperidone contains the functional groups of benzisoxazole and piperidine as part of its molecular structure. In 2003 the FDA approved risperidone for the short-term treatment of the mixed and manic states associated with bipolar disorder. In 2006 the FDA approved risperidone for the treatment of irritability in children and adolescents with autism. The FDA`s decision was based in part on a study of autistic children with severe and enduring problems of violent meltdowns, aggression, and self-injury; risperidone is not recommended for autistic children with mild aggression and explosive behavior without an enduring pattern. Like other atypical antipsychotics, risperidone has also been used off-label for the treatment of anxiety disorders, such as ...
