Antipsychotics qtc

BACKGROUND: Acute antipsychotic poisoning is correlated to a high prevalence of qt interval prolongation. AIM: This study aimed to evaluate early qt interval prolongation predictors in acute antipsychotic-poisoned patients. METHODOLOGY: This prospective cohort study enrolled 70 symptomatic patients with acute antipsychotic poisoning. Sociodemographic data, toxicological, clinical, investigation, and outcomes were collected and analyzed. The estimation of the corrected qt interval (QTc) was performed using Bazett's method...

Worldwide, acute antipsychotic poisoning results in high morbidities and mortalities. Though extrapyramidal syndromes are commonly associated, the extent of extrapyramidal syndromes in relation to the severity of antipsychotic poisoning has not been addressed yet. Thus, this study aimed to assess the Global Dystonia Rating Scale (GDRS) as an unfavorable outcomes predictive tool in acute antipsychotic poisoning. A cross-sectional study included 506 antipsychotic-poisoned patients admitted to Tanta University Poison Control Center, Egypt, over three years was conducted...

Background: Quetiapine is commonly prescribed off-label to manage delirium in intensive care unit (ICU) patients. However, limited studies comparing its efficacy and safety to those of other antipsychotics exist in the literature. Method: A retrospective, single-center chart review study was conducted on adults admitted to the ICU between January 2017 and August 2022, who were diagnosed with delirium and treated with a single antipsychotic and had no neurological medical conditions, active alcohol withdrawal, or prior use of antipsychotics...

IMPORTANCE: Antipsychotic medications, often prescribed for delirium in intensive care units (ICUs), may contribute to QTc interval prolongation. OBJECTIVE: To determine whether antipsychotics increase the QTc interval in patients with delirium in the ICU. DESIGN, SETTING, AND PARTICIPANTS: An a priori analysis of a randomized clinical trial in medical/surgical ICUs within 16 centers across the US was conducted. Participants included adults with delirium in the ICU with baseline QTc interval less than 550 ms...

BACKGROUND: Patients experiencing significant agitation or perceptual disturbances related to delirium in an intensive care setting may benefit from short-term treatment with an antipsychotic medication. Some antipsychotic medications may prolong the QTc interval, which increases the risk of potentially fatal ventricular arrhythmias. In this targeted review, we describe the evidence regarding the relationships between antipsychotic medications and QTc prolongation and practical methods for monitoring the QTc interval and mitigating arrhythmia risk...

Introduction Despite the well-established association between antipsychotics and metabolic adverse effects in psychiatric disorders, the variable influence of long-term and off-label antipsychotic medication on behavioral disorders has not been investigated in detail. Objective To clarify the impact of antipsychotic use on challenging behavior (CB) and neuropsychiatric symptoms (NPS), we evaluated the clinical findings and cardiometabolic effects in individuals with intellectual disability (ID) hospitalized in our residential facility for profoundly disabled patients...

BACKGROUND: Escitalopram can cause prolongation of the QT interval on the electrocardiogram (ECG). However, only some patients get pathological QTc prolongation in clinic. We investigated the influence of KCNQ1, KCNE1, and KCNH2 gene polymorphisms along with clinical factors on escitalopram-induced QTc prolongation. METHODS: A total of 713 patients prescribed escitalopram were identified and had at least one ECG recording in this retrospective study. 472 patients with two or more ECG data were divided into QTc prolongation (n = 119) and non-prolongation (n = 353) groups depending on the threshold change in QTc of 30 ms above baseline value (∆QTc ≥ 30 ms)...

BACKGROUND: Long QT syndrome (LQTS) is a heterogeneous syndrome that may be congenital or, more frequently, acquired. The real-world prevalence of acquired LQTS (aLQTS) in the emergency department (ED) remains to be determined. The aim of this study was to determine prevalence of aLQTS and its impact on symptoms on ED admissions. METHODS: Electrocardiograms (ECG) of 5,056 consecutively patients admitted in the ED of a tertiary hospital between January 28th and March 17th of 2020 were reviewed...

OBJECTIVE: Delirium is an acute, life-threatening neuropsychiatric disorder frequently occurring among hospitalized patients. Antipsychotic medications are often recommended for delirium management but are associated with cardiovascular risks. This study aimed to investigate the frequency and magnitude of QTc interval prolongation and clinically relevant side effects occurring in delirium patients managed with haloperidol and/or pipamperone. METHODS: This descriptive retrospective cohort study evaluated 102 elderly (mean age: 73...

BACKGROUND: Many antipsychotic drugs have been associated with QTc prolongation, which is a risk factor for sudden death. We studied the prevalence and predictors of QTc prolongation in treatment-resistant schizophrenia patients who were receiving clozapine in a real-world setting. METHODS: Data were extracted from the records of all schizophrenia patients aged 18-65 years, enrolled in a clozapine clinic in metropolitan Australia during October 2020 to April 2022, for whom ECG data were available...

BACKGROUND: QTc prolongation is one of the possible complications in patients with schizophrenia taking antipsychotics, which leads to malignant cardiac arrhythmia. No meta-analysis has been reported assessing the prevalence and correlated risk factors for QTc prolongation. METHODS: This meta-analysis aimed to assess the evidence for the prevalence of QTc prolongation and correlated risk factors in patients with schizophrenia taking antipsychotics. Web of Science and PubMed were searched according to preset strategy...

Background: Although guidelines recommend twice daily (BID) dosing of quetiapine for treatment of intensive care unit (ICU) delirium in most patients, once daily dosing at bedtime (HS) is commonly prescribed to reduce daytime somnolence. No studies have evaluated differences in outcomes. Objectives: To determine if twice daily vs bedtime dosing of quetiapine reduces the duration of ICU delirium. Methods: Retrospective analysis of ICU patients treated with twice daily vs bedtime dosing of quetiapine for ICU delirium...

BACKGROUND: In Schizophrenia (SCZ) and Bipolar Affective Disorder (BAD) patients using the Framingham Heart Risk Scoring (FHRS), we aimed to investigate the possible cardiac arrhythmia risk by calculating electrocardiogram (ECG) parameters (QT, QTc, Tpe, and TPE/QTc ratios), which are ventricular repolarization markers. SUBJECTS AND METHODS: A total of 140 BAD and 253 SCZ patients were included in the study. Age, blood test results (fasting blood glucose, LDL-HDL-TC levels, hemogram values), blood pressure and heart rate, smoking status, antihypertensive drug use, and FHRS were calculated from the patient files, and sociodemographic information was recorded...

CONTEXT: Current palliative care guidelines lack a specific treatment algorithm for nausea and emesis. Olanzapine is an atypical antipsychotic with antiemetic activity that's recommended in the guidelines for the treatment of chemotherapy induced nausea and vomiting, but outside of oncologic indications there is a lack of research. OBJECTIVES: To describe the safety and efficacy of olanzapine for nausea and emesis in the palliative care domain, excluding patients actively undergoing chemotherapy or radiation...

AIM: This study identified discrepant therapeutic outcomes of antipsychotics. METHODS: A total of 5191 patients with schizophrenia were enrolled, 3030 as discovery cohort, 1395 as validation cohort, and 766 as multi-ancestry validation cohort. Therapeutic Outcomes Wide Association Scan was conducted. Types of antipsychotics (one antipsychotic vs. other antipsychotics) were dependent variables, therapeutic outcomes including efficacy and safety were independent variables...

Most acute phase antipsychotic drug trials in schizophrenia last only a few weeks, but patients must usually take these drugs much longer. We examined the long-term efficacy of antipsychotic drugs in acutely ill patients using network meta-analysis. We searched the Cochrane Schizophrenia Group register up to March 6, 2022 for randomized, blinded trials of at least 6-month duration on all second-generation and 18 first-generation antipsychotics. The primary outcome was change in overall symptoms of schizophrenia; secondary outcomes were all-cause discontinuation; change in positive, negative and depressive symptoms; quality of life, social functioning, weight gain, antiparkinson medication use, akathisia, serum prolactin level, QTc prolongation, and sedation...

Long QT syndrome is a type of disease caused by ion channels in the heart not working properly. It is a rare condition that can affect up to one in 2000 people. Many people with this condition do not develop any symptoms; however, this can lead to heart rhythm abnormality, known as torsades de pointes, and can sometimes be fatal. The cause of this condition is often inherited; however, it can also be triggered by certain medications. But the latter tends to affect those who already tend to develop this condition...

BACKGROUND: Delirium tremens (DT) is a common complication of alcohol withdrawal. Pharmacological treatment of hospitalized patients with DT is important in addiction medicine but also in other medical disciplines where DT can occur as a complication of hospitalization. Patients suffering from DT require treatment with benzodiazepines (short-acting benzodiazepines for elderly patients to reduce accumulation), and in cases of psychotic symptoms, treatment with antipsychotics. Benzodiazepines are a first-line treatment for DT...

BACKGROUND: Ziprasidone mesylate injection is an atypical antipsychotic drug which is recently approved in China. In combination with its oral formulation, sequential therapy with ziprasidone brings new interventions to patients with agitation in the acute phase of schizophrenia. The purpose of this 7-day multicenter study conducted in China was to evaluate the efficacy and safety of ziprasidone sequential treatment through intramuscular/oral routes in agitated patients with schizophrenia...

BACKGROUND: As an atypical antipsychotic drug, olanzapine is one of the most commonly used drugs for delirium control. There are no systematic evaluations or meta-analyses of the efficacy and safety of olanzapine for delirium control in critically ill adults. OBJECTIVES: In this meta-analysis, we evaluated the efficacy and safety of olanzapine for delirium control in critically ill adults in the intensive care unit (ICU). DATA SOURCES AND METHODS: From inception to October 2022, 12 electronic databases were searched...
