Abstract
In recent years, a series of recommendations have been issued regarding the administration of drugs because of awareness of the serious side effects associated with certain classes of drugs, especially in vulnerable patients. Taking into account the obligation of the continuous improvement of professionals in the medical fields and the fact that we are in the midst of a "malpractice accusations pandemic", through this work, we propose to carry out a "radiography" of the scientific literature regarding adverse effects that may occur as a result of the interaction of drugs with the physiopathological particularities of patients. The literature reports various cases regarding different classes of drugs administration associated with adverse effects in the elderly people, such as fluoroquinolones, which can cause torsade de pointes or tendinopathy, or diuretics, which can cause hypokalemia followed by torsade de pointes and cardiorespiratory arrest. Also, children are more prone to the development of adverse reactions due to their physiological particularities, while for pregnant women, some drugs can interfere with the normal development of the fetus, and for psychiatric patients, the use of neuroleptics can cause agranulocytosis. Considering the physiopathological particularities of each patient, the drug doses must be adjusted or even completely removed from the treatment scheme, thus requiring the mandatory active participation both of clinician pharmacists and specialists in the activity of medical-pharmaceutical analysis laboratories within the structure of hospitals.

Abstract
Brexpiprazole is a relatively new drug that has no published research or applications within the paediatric population. Brexpiprazole targets multiple receptors and can manifest as multisystem symptoms when ingested in supratherapeutic quantities. In this report, we discuss the case of a child in early childhood who presented with delayed neurological and cardiac symptoms 24 hours after accidental ingestion of brexpiprazole. Due to delayed onset, this case highlights that a high index of suspicion and prolonged observation are necessary to appropriately manage brexpiprazole overdose or accidental ingestion.

Abstract
OBJECTIVE Risperidone is a potent psychotropic agent has been approved for symptomatic treatment of irritability in children and adolescents with autism spectrum disorders. However, its bitter taste and dose adjustment of liquid dosage forms are a main hurdle for patient acceptance. SIGNIFICANCE Thus, this recent study investigate the formulation of taste masked risperidone orally disintegration minitablets (ODMT) as a way of enhancing patient acceptance. METHODS Taste masked risperidone hydrogenated castor oil or Cetyl alcohol based granules were prepared using a simple melt granulation technique in different drug to lipid ratios; drug release, bitterness score of the prepared granular formulations were evaluated. DSC was also performed to detect the possible drug lipid interaction. The selected lipid-based granules were further compressed into ODMT formulations. Bitterness score was assessed by gustatory sensation test and results were compared to marketed liquid formulations of risperidone. RESULTS All the prepared ODMT formulations showed high content uniformity, with minimum dose fluctuation compared to marketed oral liquid preparations. CONCLUSION In conclusion, risperidone lipid-based granules could be formulated in different ratios by simple techniques and commonly used excipients into taste masked risperidone ODMT with accurate and flexible doses suitable for pediatric use with high taste preference and acceptability.

Abstract
The purpose of this study was to investigate the mutual effect of systemic inflammatory response syndrome (SIRS) accompanied with fibrinolysis, endotoxemia, and coagulation in severe cases of antipsychotic poisoning. A total of 199 patients were examined, of which 71 were men and 128 were women. The age of the patients was from 22 to 63 years, (45.3 ± 6.1 years on average). According to the results of the course of therapy, the patients were divided into two groups. In the blood plasma, the content of C-reactive protein, fibrinogen and its proteolysis products (oligopeptides, D-dimers), interleukin-6 were determined. In the first 1 to 3 days, in group 1, the level of interleukin-6 decreased and approached the normal level (P ≤ .05). The opposite trend continued throughout the observation of patients from group 2-their levels of interleukin-6 increased day by day (P ≤ .05). The concentration of D-dimer already in 1 day after admission to intensive care in patients from group 2 exceeded the norm by 14 times (P ≤ .05). The level of D-dimer correlated with the level of oligopeptides in blood plasma upon admission, as well as for 3 and 5 days after admission to intensive care: 0.36, 0.76 at P ≤ .05, 0.94 at P ≤ .01, respectively. Similar correlations were obtained for the content of oligopeptides in urine and the level of D-dimer: 0.55, 0.85 at P ≤ .05, 0.93 at P ≤ .01. In this regard, the most pronounced correlation is that between the SIRS score, plasma D-dimer level, and the plasma level of the D-dimer derivatives, oligopeptides.

Abstract
A 71-year-old man developed coma with severe respiratory failure, hypotension, and tachycardia induced by the intentional ingestion of quetiapine fumarate extended release (XR) 20 g. At the time, he had been treated for bipolar depression with venlafaxine 75 mg/day, lamotrigine 100 mg/day, pregabalin 75 mg/day, and quetiapine XR 400 mg/day for approximately 1 year. Comorbidities were hypertension treated with metoprolol, diabetes mellitus type 2 treated with metformin, and benign prostatic hyperplasia treated with silodosin. In the emergency room, about 4 h after ingestion of quetiapine fumarate XR, the presenting symptomatology was characterized by coma (Glasgow Coma Scale score 3), hypotension (blood pressure [BP] 90/60 mmHg), tachycardia (electrocardiogram [ECG] showed sinus tachycardia with heart rate 120 beats per minute and a QTc of 499 ms). A gastric lavage was performed and activated charcoal 50 g and magnesium sulfate 30 g was administered. About 6 h after ingestion, he developed marked desaturation and underwent mechanical ventilation; 13 h after ingestion, a severe hypotensive episode followed (BP 70/40), which was treated with an infusion of ringer lactate 500 cc. On the 3rd day after intentional overdose, an episode of agitation occurred; 4 days after ingestion, the quetiapine plasma level was found to be 42 ng/ml (within therapeutic range). At 5 days after ingestion, the patient developed septicemia caused by staphylococci (probably originating from the central vein catheter), which was treated with antibiotic therapy. On days 10 and 18 after the suicide attempt, two episodes of paroxysmal supraventricular tachycardia (PSVT) occurred and were successfully treated with intravenous adenosine triphosphate. The patient recovered completely without residual symptoms. In line with literature data, in this case report, symptoms of quetiapine overdose were tachycardia, agitation, hypotension, QT interval prolongation, and coma. A causal relationship between PSVT and quetiapine intoxication seems quite unlikely due to the drug level.

Abstract
AIM Suicidal behaviours (suicide attempts and suicides) are common among individuals experiencing, or having recently experienced, a first-episode psychosis (FEP). Current interventions for suicidal behaviours are crisis driven and focused on hospital admission of patients at imminent risk of ending their lives. This paper aims to describe ideas for universal, selective and indicated strategies that may complement existing practices to suicide risk management in first-episode patients. METHODS Key findings from the Suicidal Behaviours in FEP Project were used to develop suggested interventions. The project examined the temporal course of suicide risk, common characteristics of suicidal behaviours and predictors of suicidal behaviours in 699 patients with FEP. RESULTS Key findings included: (i) 12% of FEP cohort engaged in suicidal behaviours during treatment (up to 3 years); (ii) first month of treatment conferred the highest suicide risk; (iii) 64% of suicidal behaviours were overdoses, usually on antipsychotics; (iv) 20% of suicidal behaviours occurred on psychiatric units and all involved hanging/strangulation; (v) most suicidal behaviours were impulsive, precipitated by psychosocial stressors and with serious intent; and (vi) proximal non-suicidal self-injurious behaviour and proximal negative life events were the strongest predictors. CONCLUSION Comprehensive approach by mental health services to prevention of suicidal behaviours among first-episode patients could be facilitated by: delineating safe quantities of prescribed medications available to outpatients; regular audits of fixtures on inpatient units; enhancing risk recognition by family members; routinely monitoring suicide risk levels; developing crisis cards with all new FEP patients to facilitate help seeking during distress; and skills training programs targeting distress tolerance, interpersonal effectiveness and problem-solving.

Abstract
UNLABELLED Although paediatric patients frequently suffer from intoxications with atypical antipsychotics, the number of studies in young children, which have assessed the effects of acute exposure to this class of drugs, is very limited. The aim of this study was to achieve a better characterization of the acute toxicity profile in young children of the atypical antipsychotics clozapine, olanzapine, quetiapine, and risperidone. We performed a multicentre retrospective analysis of cases with atypical antipsychotics intoxication in children younger than 6 years, reported by physicians to German, Austrian, and Swiss Poisons Centres for the 9-year period between January 1, 2001 and December 31, 2009. One hundred and six cases (31 clozapine, 29 olanzapine, 12 quetiapine, and 34 risperidone) were available for analysis. Forty-seven of the children showed minor, 28 moderate, and 2 severe symptoms. Twenty-nine cases were asymptomatic. No fatalities were recorded. Symptoms predominantly involved the central nervous and cardiovascular systems. Minor reduction in vigilance (Glasgow Coma Scale score >9) (62 %) was the most frequently reported symptom, followed by miosis (12 %) and mild tachycardia (10 %). Extrapyramidal motor symptoms were observed in one case (1 %) after ingestion of risperidone. In most cases, surveillance and supportive care were sufficient to achieve a good outcome, and all children made full recovery. CONCLUSIONS Paediatric antipsychotic exposure can result in significant poisoning; however, in most cases only minor or moderate symptoms occurred and were followed by complete recovery. Symptomatic patients should be monitored for central nervous system depression and an electrocardiogram should be obtained.

Abstract
The authors conducted a systematic literature review of preventive pharmacological treatments for episodic childhood migraines searching several databases through May 20, 2012. Episodic migraine prevention was examined in 24 publications of randomized controlled trials that enrolled 1578 children in 16 nonrandomized studies. Single randomized controlled trials provided low-strength evidence that propranolol would result in complete cessation of migraine attacks in 713 per 1000 children treated (95% confidence interval, 452-974); trazodone and nimodipine decreased migraine days, while topiramate, divalproex, and clonidine were no more effective than placebo in preventing migraines. Migraine prevention with multidisciplinary drug management was not sustained at 6 months. Divalproex resulted in treatment discontinuation due to adverse effects, and topiramate increased the risk of paresthesia, upper respiratory tract infection, and weight loss. Long-term preventive benefits and improvement in disability and quality of life are unknown. No studies examined quality of life or provided evidence for individualized treatment decisions.

Abstract
Historically, treatment for schizophrenia focused on sedation. The advent of the typical antipsychotics resulted in treatment aimed specifically at the underlying disease, but these agents were associated with numerous adverse effects, and were not particularly effective at treatment of the negative symptoms of schizophrenia. As a result, numerous atypical agents have been developed over the past 2 decades, including several agents within the past 5 years. Overdose of antipsychotics remains quite common in Western society. In 2010, poison control centres in the US received nearly 43,000 calls related to atypical antipsychotics alone. Due to underreporting, the true incidence of overdose with atypical antipsychotics is likely much greater. Following overdose of an atypical antipsychotic, the clinical effects observed, such as CNS depression, tachycardia and orthostasis are largely predictable based on the unique receptor binding profile of the agent. This article, which focuses on the atypical antipsychotics commonly used in the treatment of schizophrenia, discusses the features commonly encountered in overdose. Specifically, agents that result in QT prolongation and the corresponding potential for torsades de pointes, as well as unique features encountered with the various medications are discussed. The diagnosis of this overdose is largely based on history. Routine use of drug screens is unlikely to be beneficial. The primary goal of management is aggressive supportive care. Patients with significant CNS depression with associated loss of airway reflexes and respiratory failure need advanced airway management. Hypotension should be treated first with intravenous fluids, with the use of direct acting vasopressors reserved for persistent hypotension. Benzodiazepines should be used for seizures, with barbiturates used for refractory seizures. Intravenous magnesium can be administered for patients with a corrected QT interval exceeding 500 milliseconds.

Abstract
BACKGROUND Second-generation antipsychotic medications, or "atypical antipsychotics," are now first-line therapy in the treatment of schizophrenia and other psychotic disorders, and are additionally being used in a wide array of other psychiatric and non-psychiatric conditions in both adults and children. Overdose is frequently reported to poison control centers. OBJECTIVES We review the toxicology and general management of poisonings involving the atypical antipsychotic medications. DISCUSSION The most serious toxicity involves the cardiovascular system and the central nervous system. All typical and atypical antipsychotics cause sedation, which is pronounced in overdose. The most common cardiovascular effects that occur after atypical antipsychotic overdose are tachycardia, mild hypotension, and prolongation of the QTc interval. Other clinical syndromes in overdose include neuroleptic malignant syndrome (NMS) and antimuscarinic delirium. Seizures may be observed. No antidotes exist for these poisonings, but they most often do well with supportive care. CONCLUSION Antipsychotic overdose produces a gamut of manifestations that affect multiple organ systems. Treatment is primarily supportive. Specific therapies for NMS, hypotension, and seizures are discussed.

[PMID: 21295450 DOI: 10.1016/j.eurpsy.2010.09.011] [Citation(s) in RCA: 236] [Impact Index Per Article: 18.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/19/2010] [Revised: 09/27/2010] [Accepted: 09/28/2010] [Indexed: 10/18/2022] Open
Abstract
Second-generation antipsychotics (SGA) are being used more often than ever before in children and adolescents with psychotic and a wide range of non-psychotic disorders. Several SGA have received regulatory approval for some paediatric indications in various countries, but off-label use is still frequent. The aim of this paper was to perform a systematic review and critically evaluate the literature on cardiometabolic and endocrine side-effects of SGA in children and adolescents through a Medline/Pubmed/Google Scholar search of randomized, placebo controlled trials of antipsychotics in children and adolescents (<18 years old) until February 2010. In total, 31 randomized, controlled studies including 3595 paediatric patients were identified. A review of these data confirmed that SGA are associated with relevant cardiometabolic and endocrine side-effects, and that children and adolescents have a high liability to experience antipsychotic induced hyperprolactinaemia, weight gain and associated metabolic disturbances. Only weight change data were sufficiently reported to conduct a formal meta-analysis. In 24 trials of 3048 paediatric patients with varying ages and diagnoses, ziprasidone was associated with the lowest weight gain (-0.04kg, 95% confidence interval [CI]: -0.38 to +0.30), followed by aripiprazole (0.79kg, 95% CI: 0.54 to 1.04], quetiapine (1.43kg, 95% CI: 1.17 to 1.69) and risperidone (1.76kg, 95% CI: 1.27 to 2.25) were intermediate, and olanzapine was associated with weight gain the most (3.45kg, 95% CI: 2.93 to 3.97). Significant weight gain appeared to be more prevalent in patients with autistic disorder who were also younger and likely less exposed to antipsychotics previously. These data clearly suggest that close screening and monitoring of metabolic side effects is warranted and that the least cardiometabolically problematic agents should be used first whenever possible. A good collaboration between child- and adolescent psychiatrists, general practitioners and paediatricians is essential to maximize overall outcomes and to reduce the likelihood of premature cardiovascular morbidity and mortality.

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
Unintentional ingestions are a common presentation to the emergency department in the pediatric population. However, very few ingestions of an atypical antipsychotic, such as ziprasidone, have been described in the emergency medicine literature. While the prevalence of these newer antipsychotics increases in the general population, emergency physicians can expect to see more patients with accidental or intentional overdoses. Many emergency physicians may be unfamiliar with the presentation, initial workup, and expected clinical course of such an overdose. We describe a case of an unintentional ingestion of ziprasidone tablets in a 22-month-old girl who presented to the emergency department with somnolence, drooling, and poor tone.

Abstract
Risperidone has been reported as a well-tolerated antipsychotic in children. The most common side effects of risperidone are anxiety, headaches, insomnia, and agitation, which frequently appear with high doses. Although it is known that risperidone affects the cardiac conduction system, symptomatic bradycardia has not been reported previously in children. We report a child who developed syncope because of sinus arrest with long pauses (>3 seconds) with therapeutic doses of risperidone. This case suggests that close monitoring is mandatory even during therapeutic treatment with risperidone.

Abstract
New generation antipsychotic (NGA) drugs introduced to the US market after clozapine (aripiprazole, olanzapine, paliperidone, quetiapine, risperidone, and ziprasidone) are frequently used in individuals with intellectual disabilities (ID). However, there is very limited research to fully establish evidence-based or personalized medicine approaches for their use in this population. These guidelines take a pragmatic approach to establishing frameworks for their use by utilizing the prescribing information and reviewing the available literature on other relevant neuropsychiatric disorders. In the absence of expert consensus guidance and well-controlled comparison trials, we present a set of guidelines to inform initiation, dosing and monitoring of use in adults. Further, in these guidelines we provide practical information on drug-drug interactions and adverse drug reactions, and a brief review of discontinuation syndromes, potential for abuse, use during pregnancy and cost considerations. We also provide drug utilization review forms for each NGA to facilitate implementation of these guidelines, these guidelines provide a practical and necessary resource for practitioners treating psychiatric disorders and challenging behaviors in adult individuals with ID.

Abstract
Information on potentially adverse exposures to the atypical antipsychotic drug ziprasidone is limited. This study described the pattern of exposures involving only ziprasidone (isolated exposures) reported to Texas poison control centers during 2001-2005. The mean dose was 666 mg. The patient age distribution was <or=5 years (11%), 6-19 years (30%), and >or=20 years (60%). The exposures were intentional in 53% of the cases. Seventy-five percent of the exposures were managed at health care facilities. The final medical outcome was classified as no effect for 39% of the cases and minor effects for 40% of the cases. Adverse clinical effects were listed for 53% of the patients; the most frequently reported being neurological (42%), cardiovascular (13%), and gastrointestinal (5%). The most frequently listed treatment was decontamination by charcoal (34%) or cathartic (28%). Potentially adverse ziprasidone exposures reported to poison control centers are likely to involve management at a health care facility and involve some sort of adverse clinical effect. With proper treatment, the outcomes of such exposures are generally favorable.

Abstract
OBJECTIVE The goal was to investigate the epidemiologic features of antipsychotic prescribing to children and adolescents in general practice in the United Kingdom. METHODS A total of 384 participating general practices from the United Kingdom General Practice Research Database were used to identify patients 0 to 18 years of age who were prescribed > or = 1 antipsychotic medication between January 1, 1992, and December 31, 2005. Annual age-specific prevalences and incidences of antipsychotic prescribing were calculated. RESULTS The overall prevalence of use of all antipsychotics increased from 1992 (0.39 users per 1000 patient-years) to 2005 (0.77 users per 1000 patient-years). The prescribing prevalence for patients 7 to 12 years of age almost tripled between 1992 (0.23 users per 1000 patient-years) and 2005 (0.61 users per 1000 patient-years). Atypical antipsychotic prescribing increased 60-fold from 1994 (0.01 users per 1000 patient-years) to 2005 (0.61 users per 1000 patient-years). However, typical antipsychotic prescribing decreased significantly from 2000 (0.44 users per 1000 patient-years) to 2005 (0.18 users per 1000 patient-years). The incidences for typical and atypical antipsychotics showed trends similar to those of the respective prevalences. However, the overall incidence (number of new starters) for all antipsychotics was relatively stable between 1992 and 2005, which suggests that patients remain on treatment longer. CONCLUSIONS The overall prevalence of antipsychotics almost doubled between 1992 and 2005; however, the rate of increase was much lower than the reported figures in the United States. The prescribing of atypical antipsychotic drugs has increased despite the lack of conclusive evidence showing their superiority over older conventional antipsychotics. Additional investigation is required to evaluate their efficacy and safety in children and adolescents.

Abstract
OBJECTIVE Although the atypical antipsychotic medications appear to be safe in patients with epilepsy, few studies have specifically addressed the use of risperidone in children with seizures. The objective of this study was to evaluate behavior improvement and seizure outcome in children with epilepsy and behavioral disorders (self-injurious, aggressive, or destructive behavior) after introduction of risperidone. METHODS In this prospective study, 54 patients were evaluated, 38 boys and 16 girls, aged 2-18 (mean=10). The dose of risperidone ranged from 0.01 to 0.14 mg/kg/day (mean=0.038 mg/kg/day). Risperidone was introduced gradually. The titration rate was determined by clinical response. The data were collected from patients' follow-up visits and clinical files. Exacerbation of seizures was established as an increase in seizure frequency after introduction of risperidone, with return to baseline seizure frequency after risperidone withdrawal. RESULTS Seizure frequency was not affected by risperidone in 51 patients (94.5%). Only two (4%) patients experienced seizure exacerbation after the introduction of risperidone. In one patient, the effect of risperidone on seizure control could not be established. After introduction of the risperidone, 38 (70.4%) patients manifested improvement in behavior. CONCLUSION Our data suggest that risperidone can be used in pediatric patients with epilepsy and that seizure outcome is not changed in most children with epilepsy and psychiatric comorbidity. In addition, behavior improvement is usually achieved in most patients.

Abstract
Use of antipsychotic medication is very common in the elderly and often an essential therapy. However, successful treatment in the elderly requires appropriate multidimensional assessment of the patient, knowledge of possible multiple co-morbidities, and awareness of the complexities of polypharmacy, age-dependent changes in pharmacokinetics and pharmacodynamics, and drug-drug interactions in this age group. Antipsychotics are known to have a number of adverse effects. New antipsychotics, such as amisulpride, clozapine, olanzapine, risperidone, quetiapine, ziprasidone, zotepine and aripiprazole, may interact with both dopamine and serotonin receptors. However, compared with conventional antipsychotics, they are less likely to cause extrapyramidal symptoms and are better tolerated in the elderly. At the same time, consistent differences between atypical antipsychotics have been demonstrated. Use of clozapine, for example, is limited by the risk of agranulocytosis, whereas this is not a disadvantage of olanzapine, risperidone, quetiapine and, more recently, ziprasidone, which are being widely used with good results in schizophrenia. However, use of the latter agents to treat the behavioural and psychological symptoms of dementia has been restricted because of recent observations of increased cardiovascular events in patients taking risperidone and olanzapine treatment. Nonetheless, careful review of the literature suggests that the available evidence does not support any causal relationship between use of risperidone or olanzapine and cardiovascular events. This article focuses on some of the main adverse effects commonly reported during administration of atypical antipsychotics to elderly patients. Such effects may be partly explained by age-related changes in pharmacokinetics and pharmacodynamics, and partly by the characteristics of the drugs themselves and their different receptor binding profiles.
