Hellings J. Pharmacotherapy in autism spectrum disorders, including promising older drugs warranting trials. World J Psychiatry 2023; 13:262-277. [PMID: 37383284 PMCID: PMC10294139 DOI: 10.5498/wjp.v13.i6.262] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/28/2022] [Revised: 03/06/2023] [Accepted: 04/18/2023] [Indexed: 06/19/2023] Open
Abstract
Available pharmacotherapies for autism spectrum disorders (ASD) are reviewed based on clinical and research experience, highlighting some older drugs with emerging evidence. Several medications show efficacy in ASD, though controlled studies in ASD are largely lacking. Only risperidone and aripiprazole have Federal Drug Administration approval in the United States. Methylphenidate (MPH) studies showed lower efficacy and tolerability for attention deficit hyperactivity disorder (ADHD) than in the typically developing (TD) population; atomoxetine demonstrated lower efficacy but comparable tolerability to TD outcomes. Guanfacine improved hyperactivity in ASD comparably to TD. Dex-troamphetamine promises greater efficacy than MPH in ASD. ADHD medications reduce impulsive aggression in youth, and may also be key for this in adults. Controlled trials of the selective serotonin reuptake inhibitors citalopram and fluoxetine demonstrated poor tolerability and lack of efficacy for repetitive behaviors. Trials of antiseizure medications in ASD remain inconclusive, however clinical trials may be warranted in severely disabled individuals showing bizarre behaviors. No identified drugs treat ASD core symptoms; oxytocin lacked efficacy. Amitriptyline and loxapine however, show promise. Loxapine at 5-10 mg daily resembled an atypical antipsychotic in positron emission tomography studies, but may be weight-sparing. Amitriptyline at approximately 1 mg/ kg/day used cautiously, shows efficacy for sleep, anxiety, impulsivity and ADHD, repetitive behaviors, and enuresis. Both drugs have promising neurotrophic properties.

Systematic Review and Meta-analysis: Pharmacological and Nonpharmacological Interventions for Persistent Nonepisodic Irritability. J Am Acad Child Adolesc Psychiatry 2023; 62:318-334. [PMID: 35714838 DOI: 10.1016/j.jaac.2022.05.012] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/26/2021] [Revised: 04/11/2022] [Accepted: 06/07/2022] [Indexed: 12/29/2022]
Abstract
OBJECTIVE This meta-analysis examined the efficacy of available pharmacological and nonpharmacological interventions for irritability among youth with autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD), disruptive behavior disorders (DBD), disruptive mood dysregulation disorder (DMDD), and/or severe mood dysregulation (SMD). METHOD Literature searches were conducted in October 2020, resulting in 564 abstracts being reviewed to identify relevant papers, with 387 articles being reviewed in full. A random effects model was used for the meta-analysis, with subgroup meta-regressions run to assess effects of study design, intervention type, medication class, and clinical population. RESULTS A total of 101 studies were included (80 pharmacological, 13 nonpharmacological, 8 combined). Despite high heterogeneity in effects (I2 = 94.3%), pooled posttreatment effect size for decreasing irritability was large (Hedges' g = 1.62). Large effects were found for pharmacological (g = 1.85) and nonpharmacological (g = 1.11) interventions; moderate effects were found for combined interventions relative to monotherapy interventions (g = 0.69). Antipsychotic medications provided the largest effect for reducing irritability relative to all other medication classes and nonpharmacological interventions. A large effect was found for youth with ASD (g = 1.89), whereas a medium effect was found for youth with ADHD/DMDD/DBD/SMD (g = 0.64). CONCLUSION This meta-analysis provides a comprehensive review of interventions targeting persistent nonepisodic irritability among youth with various psychiatric disorders. Strong evidence was found for medium-to-large effects across study design, intervention type, and clinical populations, with the largest effects for pharmacological interventions, particularly antipsychotic medications and combined pharmacological interventions, and interventions for youth with ASD.

Abstract
Objective: Antipsychotic-related prolactin changes may expose children and adolescents to severe adverse reactions (ARs) related to pubertal development and growth. We therefore aimed to assess the effects of antipsychotics on prolactin levels and associated somatic ARs in children and adolescents. Methods: We systematically searched PubMed and CENTRAL for placebo-controlled randomized trials of antipsychotics in children and adolescents aged ≤18 years, reporting prolactin levels and related ARs. We conducted a random-effect meta-analysis and assessed risk of bias version 2 (ROB2). Results: Thirty-two randomized controlled trials with an average trial duration of 6 weeks, covering 4643 participants with an average age of 13 years and a male majority of 65.3%. Risk of bias across domains was low or unclear. The following antipsychotic compounds: aripiprazole (n = 810), asenapine (n = 506), lurasidone (n = 314), olanzapine (n = 179), paliperidone (n = 149), quetiapine (n = 381), risperidone (n = 609), and ziprasidone (n = 16) were compared with placebo (n = 1658). Compared with placebo, statistically significant higher prolactin increase occurred with risperidone (mean difference [MD] = 28.24 ng/mL), paliperidone (20.98 ng/mL), and olanzapine (11.34 ng/mL). Aripiprazole significantly decreased prolactin (MD = -4.91 ng/mL), whereas quetiapine, lurasidone, and asenapine were not associated with significantly different prolactin levels than placebo. Our results on ziprasidone are based on a single study, making it insufficient to draw strong conclusions. On average, 20.8% of patients treated with antipsychotic developed levels of prolactin that were too high (hyperprolactinemia), whereas only 1.03% of patients reported prolactin-related ARs. Data were highly limited for long-term effects. Conclusions: In children and adolescents, risperidone, paliperidone, and olanzapine are associated with significant prolactin increase, whereas aripiprazole is associated with significant decrease. Despite the significant changes in prolactin level, few ARs were reported. Study protocol on PROSPERO: CRD42018116451.

Abstract
Alleviating the multiple problems of children with autism spectrum disorder (ASD) and its comorbid conditions presents major challenges for the affected children, parents, and therapists. Because of a complex psychopathology, structured therapy and parent training are not always sufficient, especially for those patients with intellectual disability (ID) and multiple comorbidities. Moreover, structured therapy is not available for a large number of patients, and pharmacological support is often needed, especially in those children with additional attention deficit/hyperactivity and oppositional defiant, conduct, and sleep disorders.

The pediatric psychopharmacology of autism spectrum disorder: A systematic review - Part I: The past and the present. Prog Neuropsychopharmacol Biol Psychiatry 2021; 110:110326. [PMID: 33857522 DOI: 10.1016/j.pnpbp.2021.110326] [Citation(s) in RCA: 34] [Impact Index Per Article: 11.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/23/2020] [Revised: 03/17/2021] [Accepted: 04/09/2021] [Indexed: 12/28/2022]
Abstract
Autism Spectrum Disorder (ASD) is a severe and lifelong neurodevelopmental disorder, with high social costs and a dramatic burden on the quality of life of patients and family members. Despite its high prevalence, reaching 1/54 children and 1/45 adults in the United States, no pharmacological treatment is still directed to core symptoms of ASD, encompassing social and communication deficits, repetitive behaviors, restricted interests, and abnormal sensory processing. The purpose of this review is to provide an overview of the state-of-the-art of psychopharmacological therapy available today for ASD in children and adolescents, in order to foster best practices and to organize new strategies for future research. To date, atypical antipsychotics such as risperidone and aripiprazole represent the first line of intervention for hyperactivity, impulsivity, agitation, temper outbursts or aggression towards self or others. Tricyclic antidepressants are less prescribed because of uncertain efficacy and important side effects. SSRIs, especially fluoxetine and sertraline, may be effective in treating repetitive behaviors (anxiety and obsessive-compulsive symptoms) and irritability/agitation, while mirtazapine is more helpful with sleep problems. Low doses of buspirone have shown some efficacy on restrictive and repetitive behaviors in combination with behavioral interventions. Stimulants, and to a lesser extent atomoxetine, are effective in reducing hyperactivity, inattention and impulsivity also in comorbid ASD-ADHD, although with somewhat lower efficacy and greater incidence of side effects compared to idiopathic ADHD. Clonidine and guanfacine display some efficacy on hyperactivity and stereotypic behaviors. For several other drugs, case reports and open-label studies suggest possible efficacy, but no randomized controlled trial has yet been performed. Research in the pediatric psychopharmacology of ASD is still faced with at least two major hurdles: (a) Great interindividual variability in clinical response and side effect sensitivity is observed in the ASD population. This low level of predictability would benefit from symptom-specific treatment algorithms and from biomarkers to support drug choice; (b) To this date, no psychoactive drug appears to directly ameliorate core autism symptoms, although some indirect improvement has been reported with several drugs, once the comorbid target symptom is abated.

Abstract
BACKGROUND Antipsychotic medication is a commonly prescribed drug class in individuals with autism spectrum disorder (ASD). However, the safety of these agents has not been fully assessed. OBJECTIVE Our objective was to investigate the safety and tolerability profile of antipsychotics in individuals with ASD. METHODS The Cochrane Library, MEDLINE, Embase and PsycINFO databases were searched up to January 2018. We included studies that reported adverse events (AEs) in participants with ASD taking first- or second-generation antipsychotic medication. The studies included in the analysis were randomized controlled trials (RCTs) and observational studies that were comparative or noncomparative and published as full text in the English language. The primary outcome of this review was AEs of any severity reported with antipsychotic use at any dose. Meta-analysis was performed on studies with child and adolescent participants to estimate the pooled prevalence of the overall AEs and the relative risk (RR) of AEs associated with antipsychotic use using a random-effects model. The Cochrane Collaboration tool and the modified Newcastle-Ottawa Scale (NOS) were used to assess the risk of bias of the included RCTs and observational studies, respectively. RESULTS In total, 54 citations fulfilled the inclusion criteria, of which 40 were RCTs and 14 were observational studies; eight RCTs were included in the meta-analysis to estimate the RR of AEs associated with antipsychotic use and seven observational studies were included to estimate the pooled prevalence of AEs. The RR of AEs with antipsychotic treatment was 22% higher than with placebo (RR 1.22; 95% confidence interval [CI] 1.11-1.34; I2 = 30.6%; p = 0.184). The estimated pooled prevalence of AEs was 50.5% (95% CI 33-67). The most commonly reported AEs were increased appetite and weight gain, which were associated with discontinuation in many participants. CONCLUSION Antipsychotic-related AEs were common among patients with ASD. Further studies to investigate the implications of antipsychotic-related AEs on health and medication adherence are warranted. PROSPERO registration number: (CRD42018083632).

Abstract
OBJECTIVE Irritability is common in pediatric autism spectrum disorder (ASD) patients. This can have major implications in child development, receptivity to behavioral therapy, as well as child and caregiver well-being. A systematic review and network meta-analysis were conducted to assess the efficacy and safety of atypical antipsychotics in treating irritability in these patients. METHODS Studies were identified from Medline, Embase, and PsycINFO from inception to March 2018. The clinical trials database was reviewed. Studies were included if they were a double-blind, randomized controlled trial utilizing the Aberrant Behavior Checklist Irritability (ABC-I) to measure the efficacy of atypical antipsychotic monotherapy. Data extraction was carried out following the Preferred Reporting Items for Systematic Reviews and Meta-analyses for network meta-analysis guidelines. The main outcome was the reduction in irritability score using the ABC-I subscale from baseline. RESULTS Eight trials comparing four interventions-risperidone, aripiprazole, lurasidone, and placebo in 878 patients, were included. Both risperidone and aripiprazole had significantly reduced ABC-I scores than placebo. Estimates of mean differences (95% credible intervals) were risperidone, -6.89 (-11.14, -2.54); aripiprazole, -6.62 (-10.88, -2.22); and lurasidone, -1.61 (-9.50, 6.23). Both risperidone and aripiprazole had similar safety. There were only eight studies included in the analysis, however, sample sizes were not small. Variance in reporting of adverse effects limited the quality of safety analysis. CONCLUSION Risperidone and aripiprazole were the two best drugs, with comparable efficacy and safety in pediatric ASD patients. These two medications could be beneficial in improving irritability in these patients.

Abstract
Neurodevelopmental disorders (NDDs), a group of disorders affecting ~1-2% of the general population, are caused by changes in brain development that result in behavioral and cognitive alterations, sensory and motor changes, and speech and language deficits. Neurodevelopmental disorders encompass a heterogeneous group of disorders including, but not limited to, Smith-Magenis syndrome, Lesch-Nyhan disease, cri du chat syndrome, Prader-Willi syndrome, pervasive developmental disorders, fragile X syndrome, Rett syndrome, Cornelia de Lange syndrome, and Down syndrome. Self-injurious behaviors (SIBs) are common in children with NDDs; depending on the specific NDD, the incidence of SIBs is nearly 100%. The management of SIBs in this population is complex, and little high-quality data exist to guide a consistent approach to therapy. However, managing SIBs is of the utmost importance for the child as well as the family and caregivers. Behavior therapies must be implemented as first-line therapy. If behavioral interventions alone fail, pharmacotherapy becomes an essential part of management plans. The limited available evidence for the use of common pharmacologic agents, such as second-generation antipsychotics, and less common agents, such as clonidine, n-acetylcysteine, riluzole, naltrexone, and topical anesthetics, is reviewed. Additional data from well-designed studies in children with NDDs are needed to gain a better understanding of this common and troublesome problem including efficacy and safety implications associated with pharmacotherapy. Until then, clinicians must rely on the limited available data, clinical expertise, and ongoing systematic monitoring when managing SIBs in children with NDDs.

Abstract
Autism spectrum disorder (ASD) is characterized by impairment in social communication and restricted patterns of behavior. Although there is no pharmacological treatment approved by the US Food and Drug Administration (FDA) for the core symptoms of ASD, there is mounting support in the literature for the management of behavioral symptoms associated with this developmental disorder, in particular, irritability and hyperactivity. Aripiprazole and risperidone are currently approved by the FDA for the treatment of irritability in youth with ASD. Though not FDA-approved, methylphenidate and guanfacine are effective for the management of hyperactivity in children with ASD. Selective serotonin reuptake inhibitors are often used in clinical practice to target anxiety and compulsions; however, there is little evidence to support its use in this population. There is a great need for further research on the safety and efficacy of existing psychotropic medications in youth with ASD, as well as the development of new treatment modalities for the core and associated behavioral symptoms.

Abstract
To date, no medication is proven to be effective in treating core symptoms of autism spectrum disorder (ASD). Psychotropic medications are widely used to target emotional and behavioural symptoms in ASD. This article reviewed evidence for pharmacotherapy, novel therapeutic agents, and Complementary and Alternative Medicine (CAM) in children and adolescents with ASD. Currently, only risperidone and aripiprazole have been approved by the US Food and Drug Administration (FDA) for treatment of irritability associated with ASD in children and adolescents. However, associated metabolic side-effects are concerning. Evidence supports use of methylphenidate and atomoxetine for attention deficit hyperactivity disorder (ADHD) symptoms and clonidine and guanfacine ER appear to be helpful. SSRIs are poorly tolerated and lack evidence in reducing restricted repetitive behaviours (RRB), anxiety, and depression. Buspirone shows promise in the treatment of RRB. The evidence is inconsistent for the effectiveness of anti-epileptic medications. Recent studies of glutamatergic, Gamma-aminobutyric acid (GABA)ergic, and cholinergic agents and oxytocin show inconsistent results. Despite wide use of CAM agents, the evidence is inconclusive. Melatonin can be helpful in reducing sleep problems. Overall, the evidence is limited for pharmacotherapy in children with ASD, and side-effects with long-term use can be burdensome.

Abstract
INTRODUCTION Individuals with autism spectrum disorder (ASD) commonly present for treatment of emotional and behavioral disturbances associated with ASD's "core" symptoms. Psychotropic medications are widely utilized in alleviating associated emotional and behavioral symptoms. AREAS COVERED Emotional and behavioral disturbances associated with ASD include irritability/severely disruptive behavior, which comprises the heaviest symptom burden; hyperactivity and other Attention-Deficit-Hyperactivity-Disorder (ADHD)-type symptoms; repetitive/stereotyped behaviors; and social withdrawal. Existing evidence for medications for each of these symptom clusters will be examined in this review. EXPERT OPINION Psychopharmacological treatment of core and associated symptoms in ASD is challenging, in large part because of the heterogeneity in the presentation of ASD. Furthermore, children and adolescents with ASD are more vulnerable to the side effects of psychopharmacological intervention than their age-matched, typically developing counterparts. Currently, risperidone and aripiprazole are the only medications that have been (relatively) reliably shown to help treat certain symptom clusters associated with ASD, namely severely disruptive behavior and hyperactivity. Recent studies have begun to look at medications with mechanisms that are novel in the treatment of ASD and that may address underlying pathophysiology and/or core symptoms such as glutamate-modulating agents. Overall, randomized, placebo-controlled studies of medications for the treatment of ASD are scarce.

Abstract
Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by persistent difficulties in social communication and social interaction, coupled with restricted, repetitive patterns of behavior or interest. Research indicates that aggression rates may be higher in individuals with ASD compared to those with other developmental disabilities. Aggression is associated with negative outcomes for children with ASD and their caregivers, including decreased quality of life, increased stress levels, and reduced availability of educational and social support. Therapeutic strategies including functional behavioral assessment, reinforcement strategies, and functional communication training may have a significant impact in reducing the frequency and intensity of aggressive behavior in individuals with ASD. Pharmacologic treatments, particularly the use of second-generation antipsychotics, may also be of some benefit in reducing aggression in individuals with ASD. With the ever-increasing rate of ASD diagnosis, development of effective therapeutic and pharmacologic methods for preventing and treating aggression are essential to improving outcomes in this disorder.

Abstract
OBJECTIVE The purpose of this study was to assess the impact of ziprasidone monoantipsychotic treatment targeting irritability in a naturalistic outpatient autism spectrum disorder (ASD) clinical setting. METHODS We examined the use of ziprasidone, predominantly in combination with other psychotropic agents, targeting irritability in 42 youth with ASD in a large ASD-specific treatment database. Mean age at start of treatment, treatment duration, final dose, body mass index (BMI), BMI Z score, and Clinical Global Impressions-Improvement Scale (CGI-I) score at final visit were determined, and changes with treatment were analyzed using paired t tests. Cardiac corrected QT (QTc) interval data were extracted from electrocardiograms when available. RESULTS Mean age at start of treatment was 11.8 years. And final mean dose of ziprasidone was 98.7 mg/day or 1.7 mg/kg/day. Seventeen (40%) participants were considered treatment responders based on the CGI-I. No changes in QTc (although only examined in nine participants), weight, BMI, or other vital signs were noted, with ziprasidone use. The rate of treatment response was less than what has been reported for the two atypical antipsychotics, risperidone and aripiprazole, approved by the Food and Drug Administration (FDA) for the treatment of irritability in autistic disorder. The response rate with ziprasidone may be more consistent with response rates for other atypical antipsychotics, although none of these agents has been studied in larger-scale double-blind, placebo-controlled trials. The lower rate of response to ziprasidone in this open-label trial is likely influenced by the treatment-refractory nature of the population studied. CONCLUSIONS The weight neutrality of ziprasidone appears favorable compared with other second generation antipsychotics in this population. The response rate to ziprasidone targeting irritability may be lower than response rates associated with FDA-approved agents for this indication. Overall, ziprasidone use appeared well tolerated in youth with ASD.

Abstract
PURPOSE OF REVIEW Although there is no known efficacious pharmacotherapy for core symptoms of autism spectrum disorder (ASD), psychotropic medications are commonly prescribed for behavioral/emotional symptoms associated with ASD. We reviewed current evidence-based pharmacotherapy options and updates from recent noteworthy studies. RECENT FINDINGS Atypical antipsychotics, particularly risperidone and aripiprazole, are effective in reducing irritability, stereotypy and hyperactivity. Metabolic adverse events, including weight gain and dyslipidemia, are common. Methylphenidate is effective in reducing attention-deficit hyperactivity disorder (ADHD) symptoms. Atomoxetine and alpha-2 agonists appear effective in reducing ADHD symptoms. Selective serotonin reuptake inhibitors are not effective in improving repetitive behaviors in children with ASD, and frequently cause activating adverse events. Efficacy of antiepileptic drugs is inconclusive. Overall, efficacy and tolerability of pharmacotherapy in children with ASD are less favorable than data seen in typically developing children with similar symptoms. Newer agents, including glutamatergic agents and oxytocin, appear promising albeit with mixed results. SUMMARY Current evidence-based pharmacotherapy options in children with ASD are very limited, and many have substantial adverse events. Clinicians should use pharmacotherapy as a part of comprehensive treatment, and judiciously weigh risks and benefits. New pharmacotherapy options for core symptoms as well as co-occurring symptoms of ASD are in urgent need.

Abstract
OBJECTIVE To evaluate the effect of antipsychotics on the corrected QT (QTc) interval in youth. METHOD We searched PubMed (http://www.ncbi.nlm.nih.gov/pubmed) for randomized or open clinical trials of antipsychotics in youth <18 years with QTc data, meta-analyzing the results. Meta-regression analyses evaluated the effect of age, sex, dose, and study duration on QTc. Incidences of study-defined QTc prolongation (>440-470 milliseconds), QTc >500 milliseconds, and QTc change >60 milliseconds were also evaluated. RESULTS A total of 55 studies were meta-analyzed, evaluating 108 treatment arms covering 9 antipsychotics and including 5,423 patients with QTc data (mean age = 12.8 ± 3.6 years, female = 32.1%). Treatments included aripiprazole: studies = 14; n = 814; haloperidol: studies = 1; n = 15; molindone: studies = 3; n = 125; olanzapine: studies = 5; n = 212; paliperidone: studies = 3; n = 177; pimozide: studies = 1; n = 25; quetiapine: studies = 5; n = 336; risperidone: studies = 23; n = 2,234; ziprasidone: studies = 10, n = 523; and placebo: studies = 19, n = 962. Within group, from baseline to endpoint, aripiprazole significantly decreased the QTc interval (-1.44 milliseconds, CI = -2.63 to -0.26, p = .017), whereas risperidone (+1.68, CI = +0.67 to +2.70, p = .001) and especially ziprasidone (+8.74, CI = +5.19 to +12.30, p < .001) significantly increased QTc. Compared to pooled placebo arms, aripiprazole decreased QTc (p = .007), whereas ziprasidone increased QTc (p < .001). Compared to placebo, none of the investigated antipsychotics caused a significant increase in the incidence of the 3 studied QTc prolongation measures, but there was significant reporting bias. CONCLUSION Based on these data, the risk of pathological QTc prolongation seems low during treatment with the 9 studied antipsychotics in otherwise healthy youth. Nevertheless, because individual risk factors interact with medication-related QTc effects, both medication and patient factors need to be considered when choosing antipsychotic treatment.

Abstract
INTRODUCTION Multiple strategies exist for the pharmacological treatment of schizophrenia and related disorders. In the last 20 years, several 'new' compounds have been introduced, called 'atypical antipsychotics', which have higher efficacy and better tolerability than first-generation neuroleptics. Among them, ziprasidone (ZPR) is currently finding widespread use, and it has also been shown to be active as an augmenter in bipolar disorder therapy. AREAS COVERED This review aims to provide the latest information on ZPR, an 'atypical' agent for the pharmacological therapy of schizophrenia and bipolar disorder. A literature search has been carried out with the keywords 'ziprasidone', 'schizophrenia', 'psychosis', 'bipolar', 'pharmacokinetics' and 'clinical trials'. In this process, particular attention has been paid to the drug pharmacokinetic characteristics and its safety in clinical use. EXPERT OPINION ZPR shares most advantages and disadvantages with other atypical antipsychotics. However, it can be useful for its low tendency to cause metabolic syndrome and hyperprolactinaemia, especially in patients suffering from excess weight, hyperlipidaemia, diabetes or who have suffered from hyperprolactinaemia when using other antipsychotics. However, there are serious doubts as to whether ZPR should be administered to patients suffering from arrhythmias or QTc prolongation, and even more for administration to bipolar patients undergoing polypharmacy with antidepressants.

Abstract
We comprehensively reviewed published literature to determine whether it supported the link between corrected QT (QTc) interval prolongation and torsade de pointes (TdP) for the 11 second-generation antipsychotics and seven second-generation antidepressants commonly implicated in these complications. Using PubMed and EMBASE, we identified four thorough QT studies (one each for iloperidone, ziprasidone, citalopram, and escitalopram), 40 studies specifically designed to assess QTc interval prolongation or TdP, 58 publications based on data from efficacy and safety trials, 18 toxicology studies, and 102 case reports. Thorough QT studies, QTc prolongation-specific studies, and studies based on efficacy and safety trials did not link drug-associated QTc interval prolongation with TdP. They only showed that the drugs reviewed caused varying degrees of QTc interval prolongation, and even that information was not clear and consistent enough to stratify individual drugs for this risk. The few toxicology studies provided valuable information but their findings are pertinent only to situations of drug overdose. Case reports were most informative about the drug-QTc interval prolongation-TdP link. At least one additional well established risk factor for QTc prolongation was present in 92.2 % of case reports. Of the 28 cases of TdP, six (21.4 %) experienced it with QTc interval <500 ms; 75 % of TdP cases occurred at therapeutic doses. There is little evidence that drug-associated QTc interval prolongation by itself is sufficient to predict TdP. Future research needs to improve its precision and broaden its scope to better understand the factors that facilitate or attenuate progression of drug-associated QTc interval prolongation to TdP.

Abstract
Children with autism have a high rate of irritability and aggressive symptoms. Irritability or self-injurious behavior can result in significant harm to those affected, as well as to marked distress for their families. This paper provides a literature review regarding the efficacy and tolerability of pharmacotherapy for the treatment of irritability in autistic children. Although antipsychotics have not yet been approved for the treatment of autistic children by many countries, they are often used to reduce symptoms of behavioral problems, including irritability, aggression, hyperactivity, and panic. However, among antipsychotics, the Food and Drug Administration has approved only risperidone and aripiprazole to treat irritability in autism. Among atypical antipsychotics, olanzapine and quetiapine are limited in their use for autism spectrum disorders in children because of high incidences of weight gain and sedation. In comparison, aripiprazole and ziprasidone cause less weight gain and sedation. However, potential QTc interval prolongation with ziprasidone has been reported. Contrary to ziprasidone, no changes were evident in the QT interval in any of the trials for aripiprazole. However, head-to-head comparison studies are needed to support that aripiprazole may be a promising drug that can be used to treat irritability in autistic children. On the other hand, risperidone has the greatest amount of evidence supporting it, including randomized controlled trials; thus, its efficacy and tolerability has been established in comparison with other agents. Further studies with risperidone as a control drug are needed.

Abstract
Recent reports have illustrated a dramatic rise in the use of antipsychotics in preschool children, medications originally designed and licensed for the treatment of adult psychotic disorders. Within this context, the current usage and the associated diagnoses are reviewed and compared with official guidelines and licensing for such use, highlighting a controversial challenge for clinicians. A review of the evidence base of the relative efficacy of such medications for a range of disorders is given. Associated safety and side effects are discussed, with compelling evidence for increased adverse events associated with use of antipsychotics in preschoolers, and neurodevelopmental hypotheses are used to guide predictions of long-term risk. An apparent gap in the literature and evidence base supporting such use and elucidating the risks and benefits leaves a challenge for clinicians and researchers and hinders the development of appropriate guidelines. Pragmatism in clinical practice, mindful of the limited evidence base that does exist and the propensity for harm, is necessary; far more research is required in this important area.

Abstract
RATIONALE Autism and related pervasive developmental disorders (PDD) are characterized by impairments in social interaction and communication, restricted interests, and repetitive and stereotyped patterns of behavior. Individuals with PDD frequently display irritability and disruptive behaviors including tantrums, self-injurious behavior, and aggression. Atypical antipsychotics are currently the most efficacious pharmacological interventions available for treatment of irritability associated with PDD. OBJECTIVES This article aims to review the body of literature pertaining to the use of atypical antipsychotics in the treatment of patients with PDD. METHODS A PubMed literature search was conducted using the following key words: autism, pervasive developmental disorders, atypical antipsychotics, risperidone, aripiprazole, quetiapine, ziprasidone, olanzapine, clozapine, paliperidone, iloperidone, asenapine, and lurasidone. Search terms were limited to English language, human subjects, and publication from 1999 to present. Relevant references from identified articles were also reviewed. RESULTS The efficacy and tolerability of risperidone and aripiprazole for the treatment of irritability in autism have been established with multi-site, randomized, controlled trials. Studies supporting the use of other atypical antipsychotics are either limited in scope or less robust in their findings, though newer agents such as ziprasidone and paliperidone show promise. CONCLUSIONS Atypical antipsychotics are currently first-line pharmacological agents for the treatment of irritability and associated behaviors in children with PDD. Further placebo-controlled studies are warranted to characterize the efficacy and tolerability of the majority of these medications. There is also a need for the development of novel, targeted drugs with more favorable long-term side effect profiles.

Abstract
After participating in this educational activity, the physician should be better able to1. Prescribe the appropriate psychotropic medication to treat symptoms of ASD.2. Identify the side effects of the psychotropic medications used to treat ASD.Autism spectrum disorders (ASDs) are characterized by core deficits in social communication and language, and restrictive and repetitive behaviors that cause significant functional impairment and distress for affected individuals and their caregivers. The increasing prevalence of ASD, most recently estimated as 1 in 88 children, presents an ever-increasing burden on families, schools, medical systems, and society at large. Individuals with ASD commonly present for treatment of associated emotional and behavioral disturbances that include anxiety, symptoms of ADHD, compulsions and other repetitive behaviors, mood lability, irritability, aggression, and sleep disturbance. Psychotropic medications are widely utilized in alleviating these symptoms, though rigorous clinical trials in ASD are lacking for most areas of impairment. Strong evidence from randomized, placebo-controlled trials supports the use of atypical antipsychotics, particularly risperidone and aripiprazole, for managing severe irritability and aggression in ASD. Serotonin reuptake inhibitors are commonly used to treat anxiety and compulsions, though reports of efficacy in the literature are mixed, and behavioral side effects in children are common. Minimal evidence supports the utility of anticonvulsants and traditional mood stabilizers in managing mood lability and aggression. Stimulant and nonstimulant ADHD medications can be effective for reducing hyperactivity, inattention, and impulsivity, though to a lesser degree than in ADHD populations without ASD and with greater risk of adverse effects. Psychopharmacological interventions in development for core symptoms of autism include those that target the glutamatergic and GABAergic neurotransmitter systems and the neuropeptide oxytocin. Further research is needed to establish evidence-based interventions in ASD populations.

Abstract
Individuals diagnosed with autism spectrum disorders (ASD) often exhibit serious behavioral disturbance (irritability) including severe tantrums, aggression, and self-injury that requires pharmacologic management. Research focused on the treatment of severe irritability has primarily involved the atypical antipsychotics, including risperidone and aripiprazole. Anticonvulsants have also been investigated for targeting serious behavioral disturbance; however findings have been mixed. Advances in the pharmacotherapy of irritability in ASD continue to inform practice. Research is needed to develop safer and more effective drug treatments for serious behavioral disturbance in this population.

Abstract
Research suggests that the prevalence of obesity in children with autism spectrum disorder (ASD) is at least as high as that seen in typically developing children. Many of the risk factors for children with ASD are likely the same as for typically developing children, especially within the context of today's obesogenic environment. The particular needs and challenges that this population faces, however, may render them more susceptible to the adverse effects of typical risk factors, and they may also be vulnerable to additional risk factors not shared by children in the general population, including psychopharmacological treatment, genetics, disordered sleep, atypical eating patterns, and challenges for engaging in sufficient physical activity. For individuals with ASD, obesity and its sequelae potentially represent a significant threat to independent living, self-care, quality of life, and overall health.

Abstract
Autism Spectrum Disorder (ASD) is a complex neurodevelopmental disorder with both core symptoms and associated symptoms (eg, irritability, aggression, and comorbidities) that affect both the individual and the family/systems around them. There have been recent advances in the understanding of the underlying pathophysiology of ASD pertaining to genetics, epigenetics, neurological, hormonal, and environmental factors that contribute to the difficulties found in individuals with ASD. With this improved understanding, there has been a shift in the application of psychopharmacology in ASD and its related disorders. A literature review was conducted to examine research published in the last 5 years between different classes of psychotropic medications and ASD. The broad scope of the existing literature for the use of conventional medications is summarized and novel medications are discussed.

Abstract
BACKGROUND Autism is a pervasive neurodevelopmental disorder. At present there are no defined mechanisms of pathogenesis and therapy is mostly limited to behavioral interventions. Stem cell transplantation may offer a unique treatment strategy for autism due to immune and neural dysregulation observed in this disease. This non-randomized, open-label, single center phase I/II trial investigated the safety and efficacy of combined transplantation of human cord blood mononuclear cells (CBMNCs) and umbilical cord-derived mesenchymal stem cells (UCMSCs) in treating children with autism. METHODS 37 subjects diagnosed with autism were enrolled into this study and divided into three groups: CBMNC group (14 subjects, received CBMNC transplantation and rehabilitation therapy), Combination group (9 subjects, received both CBMNC and UCMSC transplantation and rehabilitation therapy), and Control group (14 subjects, received only rehabilitation therapy). Transplantations included four stem cell infusions through intravenous and intrathecal injections once a week. Treatment safety was evaluated with laboratory examinations and clinical assessment of adverse effects. The Childhood Autism Rating Scale (CARS), Clinical Global Impression (CGI) scale and Aberrant Behavior Checklist (ABC) were adopted to assess the therapeutic efficacy at baseline (pre-treatment) and following treatment. RESULTS There were no significant safety issues related to the treatment and no observed severe adverse effects. Statistically significant differences were shown on CARS, ABC scores and CGI evaluation in the two treatment groups compared to the control at 24 weeks post-treatment (p < 0.05). CONCLUSIONS Transplantation of CBMNCs demonstrated efficacy compared to the control group; however, the combination of CBMNCs and UCMSCs showed larger therapeutic effects than the CBMNC transplantation alone. There were no safety issues noted during infusion and the whole monitoring period. TRIAL REGISTRATION ClinicalTrials.gov: NCT01343511, Title "Safety and Efficacy of Stem Cell Therapy in Patients with Autism".

Abstract
INTRODUCTION Low levels of blood cholesterol have been found in some children with autism spectrum disorders (ASD). Psychotropic medications, commonly used by people with ASD and people with intellectual disabilities (ID) are frequently associated with altered metabolic profiles. PURPOSE We aimed to compare metabolic features of adults with ASD or ID with those of a community-based population. SUBJECTS AND METHODS Data on blood fasting glucose (FBG), lipid profile, liver enzyme profile, TSH, BMI, medications and diagnoses of 80 adults with ASD, 77 adults with ID and 828 control adults were drawn from medical charts/database. Candidates that used glucose or lipid lowering medications were not included. RESULTS Total-cholesterol levels of people with ASD and ID were significantly lower than those of the controls (168.3 ± 32.78, 168.2 ± 32.91, 185.4 ± 40.49 mg/dL, respectively, P<0.001) but after adjusting for gender, age and BMI and using Bonferroni correction, the significance was lost. Compared to controls, ASD and ID had significantly lower FBG (by -14.45 ± 1.81, -14.58 ± 1.54 mg/dl, respectively; P<0.001 for both) and liver enzymes, despite using psychotropic medications. DISCUSSION AND CONCLUSION In contrast to other psychiatric patients receiving similar medications, people with ASD and ID have unaltered lipid profiles and lower glucose and liver enzyme levels compared to a community-based population.

Abstract
This review outlines pharmacologic treatments for the behavioral symptoms associated with autism spectrum disorders (ASDs) in children, adolescents, and adults. Symptom domains include repetitive and stereotyped behaviors, irritability and aggression, hyperactivity and inattention, and social impairment. Medications covered include serotonin reuptake inhibitors (SRIs), mirtazapine, antipsychotics, psychostimulants, atomoxetine, α-2 agonists, D-cycloserine, and memantine. Overall, SRIs are less efficacious and more poorly tolerated in children with ASDs than in adults. Antipsychotics are the most efficacious drugs for the treatment of irritability in ASDs, and may be useful in the treatment of other symptoms. Psychostimulants demonstrate some benefit for the treatment of hyperactivity and inattention in individuals with ASDs, but are less efficacious and associated with more adverse effects compared with individuals with ADHD. D-cycloserine and memantine appear helpful in the treatment of social impairment, although further research is needed.

Abstract
BACKGROUND AND OBJECTIVE Hyperactivity, impulsivity, and inattention (referred to as "ADHD [attention-deficit/hyperactivity disorder] symptoms") occur in 41% to 78% of children with autism spectrum disorders (ASDs). These symptoms often affect quality of life, interfering with learning or interventions that target primary ASD symptoms. This practice pathway describes the guidelines for evaluation and treatment of children and adolescents with ASD and comorbid ADHD symptoms. METHODS Current research in this area is limited, and, therefore, these recommendations are based on a systematic literature review and expert consensus in the Autism Speaks Autism Treatment Network Psychopharmacology Committee. RESULTS The recommended practice pathway includes the Symptom Evaluation Pathway for systematic assessment of ADHD symptoms across settings; examination for comorbid sleep, medical, or psychiatric comorbidities that may contribute to symptoms; and evaluation of behavioral interventions that may ameliorate these symptoms. For children for whom medication is being considered to target the ADHD symptoms, the medication choice pathway provides guidance on the selection of the appropriate agent based on a review of available research, assessment of specific advantages and disadvantages of each agent, and dosing considerations. CONCLUSIONS These recommendations provide a framework for primary care providers treating children who have ASD and ADHD symptoms. Our systematic review of the current evidence indicates the need for more randomized controlled trials of the medications for ADHD symptoms in ASD. There will also be a need for studies of the effectiveness of these practice pathways in the future.

Abstract
Autism spectrum disorders (ASDs) are neurobehavioral disorders characterized by abnormalities in three behavioral domains including social interaction, impaired communication, and repetitive stereotypic behaviors. ASD affects approximately 1% of children and is on the rise with significant genetic mechanisms underlying these disorders. We review the current understanding of the role of genetic and metabolic factors contributing to ASD with the use of new genetic technology. Fifty percent is diagnosed with chromosomal abnormalities, small DNA deletions/duplications, single-gene conditions, or metabolic disturbances. Genetic evaluation is discussed along with psychiatric treatment and approaches for selection of medication to treat associated challenging behaviors or comorbidities seen in ASD. We emphasize the importance of prioritizing treatment based on target symptom clusters and in what order for individuals with ASD, as the treatment may vary from patient to patient.

Abstract
At present, no evidence-based effective pharmacologic options are available for treating the core deficits of autism spectrum disorders (ASDs), which are best addressed by behavioral and educational interventions. However, such evidence exists for several of the frequently associated/comorbid symptoms such as aggression and severe irritability, hyperactivity, and repetitive behaviors, which can become a major source of additional distress and interference in functioning. This article offers information on the psychopharmacology of ASD that is current, relevant, and organized in a user-friendly manner, to form a concise but informative reference guide for primary pediatric clinicians.

Abstract
OBJECTIVE To assess the incidence of symptoms (palpitations, syncope) and electrocardiographic signs (increased QT duration and dispersion) of an increased risk of torsades de pointes in youth treated with ziprasidone. METHOD Data for this study were collected as part of a prospective, observational, mixed inpatient and outpatient cohort study of youth who were administered antipsychotic treatment for the first time. For this study, we focus on 29 patients (mean ± SD age 15.3 ± 2.9 years) receiving ziprasidone (112.8 ± 50.6 mg/d; range, 20-240) for 99.3 ± 108.7 days. All patients had normal electrocardiograms (ECGs) and no serious medical illness at baseline. Patients had a mean of 2.7 ± 1.3 (median = 3; range, 1-7; total = 49) follow-up ECGs performed monthly for 3 months and every 3 months thereafter, with concurrent blood ziprasidone level measurements. Heart rate-corrected QT interval (QTc) duration and dispersion were measured manually in ≥ 6 ECG leads. QTc > 450-millisecond or ≥ 60-millisecond increase and QTc dispersion > 100 milliseconds were considered abnormal. The study was conducted from December 2001 to September 2007. RESULTS No patient reported syncope or symptomatic arrhythmias. Seven patients (24.1%) developed ECG abnormalities; 5 had peak QTc durations > 450 milliseconds, and 2 had peak QTc dispersion > 100 milliseconds. The baseline-to-peak QTc duration increased by 22.9 ± 21 milliseconds (P < .0001). The baseline-to-peak QTc dispersion increased by 6.1 ± 31.4 milliseconds (P = .30). The peak QTc duration and dispersion occurred after 47.6 ± 46.0 and 60.4 ± 73.2 treatment days, respectively. Baseline-to-peak QTc duration and dispersion changes were not correlated with ziprasidone dose (P = .65) or plasma levels (P = .50). CONCLUSIONS Ziprasidone was associated with a dose- and level-independent, significant prolongation of QTc duration in one-quarter of youth. However, prolongation of QTc dispersion was nonsignificant, and no patient experienced concomitant abnormal prolongation of both QTc duration and QTc dispersion. The dissociation between prolonged QTc duration and dispersion suggests low arrhythmogenic potential in youth with normal baseline ECGs.

Abstract
Ziprasidone is an atypical antipsychotic approved for the treatment of schizophrenia and bipolar mania in adults and is used off label in children and adolescents. Despite increasing use of ziprasidone in both adult and pediatric populations, there remains a paucity of reports describing unintentional pediatric exposures. The following report describes a patient with isolated ziprasidone ingestion who required intubation secondary to respiratory failure. A 15-month-old previously healthy boy presented to the emergency department shortly after his father found him with approximately five partially dissolved 80-mg ziprasidone tablets in his mouth. The child was flaccid and lethargic with no eye opening, withdrawing from pain only. Two hours after arrival, he developed worsening CNS depression with inability to protect his airway and underwent endotracheal intubation. A serum ziprasidone level was 330 ng/mL by LC/MS. The patient was extubated approximately 14 h later and was discharged from the hospital shortly thereafter in good health without neurological sequelae. Isolated pediatric ingestion of ziprasidone resulting in the need for significant medical intervention has not been previously reported. We report a case of respiratory failure requiring intubation following accidental ziprasidone ingestion with confirmatory serum levels.

Abstract
This publication, by reviewing 1300 studies published on autism in 2008, represents an update on this topic. Results include possible parental influences, maternal conditions, and studies on genes and chromosomes. Possible etiological factors involve the "extreme male brain," defects in the mirror neuron system, vaccines, underconnectivity, disorders of central coherence, and many other more specific etiologies. Assessments or tests for autism are also reviewed. Characteristics of autistic individuals include repetitive behavior, language disorders, sleep disturbances, social problems, joint attention disorders, seizures, allergic reactions, and various behavioral changes. Cognitive changes involve IQ, reasoning, and verbal and language disorders. The savant syndrome is a fascinating phenomenon, at times seen in autistic individuals. Neurophysiological and neuroanatomical changes are also reviewed, as are comorbid conditions. Finally, treatment involves various medications including risperidone, ziprasidone, and antipsychotic drugs, as well as different procedures such as magnetic stimulation, acupuncture, and hyperbaric oxygen therapy. As mentioned in the 2007 survey, nearly every conceivable problem that a child can have may be found in these unfortunate children and nearly every conceivable etiology has been mentioned to account for this serious disorder.

Abstract
OBJECTIVE This review reports the incidence of hyperprolactinemia, its relationship with genotype, and prolactin-related side effects in children and adolescents treated with antipsychotics. METHOD Data on prolactin levels were available for haloperidol, pimozide, risperidone, olanzapine, clozapine, ziprasidone, and quetiapine. Twenty-nine studies were selected after a literature search in the English Medline/Embase/Psychinfo/EBM databases (1965 to August, 2008). RESULTS All antipsychotics, except clozapine, ziprasidone, and quetiapine, increase the mean prolactin level from baseline values of 8.0 ng/mL to 25-28 ng/mL after 4 weeks of treatment (reference range 0-15 ng/mL). The most and best data are available for risperidone. Five risperidone studies (n = 577) show an increase of prolactin level from 7.8 ng/mL to 17.7 ng/mL after 1 year of treatment, and two risperidone studies (n = 60) show an increase from 7.4 ng/mL to 24.9 ng/mL after 2 years of treatment. Aggregated over all antipsychotics, prolactin-related side effects, such as gynecomastia, galactorrhea, irregular menses, and sexual dysfunction, were reported by 4.8% of the children and adolescents. No data are available on bone mineral density in relation to antipsychotic-induced hyperprolactinemia in children and adolescents. Prolactin levels may be influenced by the genetic differences that influence prolactin metabolism and D2 dopamine receptor density. CONCLUSION Persistent elevation of prolactin for periods up to 2 years has been documented in maintenance treatment with risperidone. Very limited long-term data of pimozide, olanzapine, and quetiapine prohibit drawing conclusions for these antipsychotics. Systematic long-term observational studies, including specific questionnaires as well as physical examination, are needed to investigate prolactin-related side effects of antipsychotic treatment in children and adolescents.

Abstract
Autistic disorder or autism is a serious childhood-onset disorder that affects all areas of development, particularly in the areas of language, communication and reciprocal social interaction. Patients with autistic disorder typically demonstrate repetitiveness and a restricted repertoire of behaviour. Additionally, they also have a number of disruptive symptoms that may be reduced by drug treatment, including severe tantrums, hyperactivity and lability. Antipsychotic drugs are the agents that are the most critically studied as treatments for reducing symptoms. Both first- and second-generation antipsychotics have shown safety and efficacy in short- and long-term studies in autism. The most studied antipsychotic drugs include haloperidol and risperidone, although studies of other antipsychotic drugs are underway. Safety concerns associated with treatment include the risk of drug-related dyskinesias, which is greater with the first-generation drugs, and the risk of weight gain and associated metabolic problems (i.e. increases in glucose and lipids), which is greater with second-generation agents. Prescription of antipsychotic drugs requires careful monitoring because of these safety risks and the likelihood of long-term use. Drug administration should be initiated at low dosages and subsequent dosage changes should be based on tolerability and clinical response.

Abstract
OBJECTIVE The aim of this study was to determine the effectiveness and tolerability of aripiprazole for irritability in pervasive developmental disorder not otherwise specified (PDD-NOS) and Asperger's disorder. METHOD This is a 14-week, prospective, open-label investigation of aripiprazole in 25 children and adolescents diagnosed with PDD-NOS or Asperger's disorder. Primary outcome measures included the Clinical Global Impressions-Improvement (CGI-I) scale and the Irritability subscale of the Aberrant Behavior Checklist (ABC-I). RESULTS Twenty-five subjects, ages 5-17 years (mean 8.6 years) received a mean final aripiprazole dosage of 7.8 mg/day (range 2.5-15 mg/day). Full-scale intelligence quotient (IQ) scores ranged from 48 to 122 (mean 84). Twenty-two (88%) of 25 subjects were responders in regard to interfering symptoms of irritability, including aggression, self-injury, and tantrums, with a final CGI-I of 1 or 2 (very much or much improved) and a 25% or greater improvement on the ABC-I. The final mean CGI-I was 1.6 (p CONCLUSIONS These preliminary data suggest that aripiprazole may be effective and well tolerated for severe irritability in pediatric patients with PDD-NOS or Asperger's disorder. Larger-scale placebo-controlled studies are needed to elucidate the efficacy and tolerability of aripiprazole in this understudied population.

Abstract
The growing literature shows the pervasiveness and importance of comorbidity in youth with bipolar disorder (BPD). For instance, up to 90% of youth with BPD have been described to manifest comorbidity with attention-deficit hyperactivity disorder. Multiple anxiety, substance use, and disruptive behavior disorders are the other most commonly reported comorbidities with BPD. Moreover, important recent data highlight the importance of obsessive-compulsive and pervasive developmental illness in the context of BPD. Data suggest that not only special developmental relationships are operant in the context of comorbidity but also that the presence of comorbid disorders with BPD results in a more severe clinical condition. Moreover, the presence of comorbidity has therapeutic implications for the treatment response for both BPD and the associated comorbid disorder. Future longitudinal studies to address the relationship and the impact of comorbid disorders on course and therapeutic response over time are required in youth with BPD.

Abstract
OBJECTIVE To review published literature regarding ziprasidone in child and adolescent psychiatry. METHODS A literature review was conducted using the medline search term: 'ziprasidone' with limits: Human trials, English language, All Child (Age 0-18). Additional articles were identified from reference information and poster presentation data. RESULTS Two randomized controlled trials and five prospective open-label studies have been conducted with ziprasidone. Additionally, several case reports and case series are reviewed. Ziprasidone has a greater propensity for QT(c) prolongation and risk for fatal arrhythmias compared to other atypical antipsychotics. Careful history taking regarding presence of congenital long QT syndrome is essential. Given limited clinical experience, electrocardiogram monitoring at baseline and following attainment of ziprasidone target dosage is warranted. No deaths from overdose have been reported in children and adolescents. Ziprasidone has a low potential for extrapyramidal side effects. Prolactin changes are small and transient. Lethargy, drowsiness, agitation and tachycardia were the most common adverse effects in randomized trials. Body weight changes with ziprasidone were comparable to placebo-treated subjects. CONCLUSION At present, ziprasidone should be considered a second or third-line option for a limited set of conditions. A role may exist for ziprasidone in patients who have experienced significant metabolic adverse effects with other atypical antipsychotics.

Abstract
We reviewed the recent literature on medicines used to manage inattention, impulsiveness, and overactivity in children with pervasive developmental disorders (autistic disorder, pervasive developmental disorder not otherwise specified, Asperger's disorder) using computer searches of pharmacologic studies. A substantial number of reports were identified and summarized. The literature tends to be dominated by uncontrolled studies, although the number of controlled trials is growing. Findings are described for psychostimulants, noradrenergic reuptake inhibitors, antipsychotics, alpha adrenergic agonists, antidepressants, anxiolytics, cholinesterase inhibitors, N-methyl-D-aspartate receptor blockers, and antiepileptic mood stabilizers. Evidence for a positive effect is strongest for psychostimulants, noradrenergic reuptake inhibitors, antipsychotics, and alpha adrenergic agonists. Evidence for efficacy seems weakest for newer antidepressants, anxiolytics, and mood stabilizers.
