metformin risperidone

The metabolic effects induced by antipsychotics in vitro depend on their action on the trafficking and biosynthesis of sterols and lipids. Previous research showed that antipsychotics with different adverse effects in patients cause similar alterations in vitro, suggesting the low clinical usefulness of cellular studies. Moreover, the inhibition of peripheral AMPK was suggested as potential aetiopathogenic mechanisms of olanzapine, and different effects on autophagy were reported for several antipsychotics...

RATIONALE: Risperidone is the first antipsychotic to be approved by Food and Drug Administration (FDA) for treating autism spectrum disorder (ASD). The potential efficacy of metformin in preventing and/or controlling ASD behavioral deficits was also recently reported. Suppression of hippocampus autophagy was suggested as a potential pathologic mechanism in ASD. OBJECTIVES: Is metformin's ability to improve ASD clinical phenotype driven by its autophagy-enhancing properties? And does hippocampus autophagy enhancement underlie risperidone's efficacy as well? Both questions are yet to be answered...

BACKGROUND: Drug repurposing refers to the application of existing drugs to new therapeutic indications. As phenotypic indicators of human drug response, drug side effects may provide direct signals and unique opportunities for drug repurposing. OBJECTIVES: We aimed to identify drugs frequently associated with hypohidrosis or anhidrosis adverse reactions (that is, the opposite condition of hyperhidrosis) from the pharmacovigilance database, which could be potential candidates as anti-hyperhidrosis treatment agents...

BACKGROUND: One of the most frequent side effects of atypical antipsychotics is hyperprolactinemia (HPRL), and metformin or aripiprazole co-prescription is regarded as an effective therapy option for reducing prolactin (PRL) levels. However, whether either of the two drugs can reduce PRL levels in patients with long-term hospitalized chronic schizophrenia with co-morbid type 2 diabetes (T2DM) has not been adequately reported. METHODS: In our study, long-term hospitalized chronic schizophrenia patients with co-T2DM who were prescribed olanzapine or risperidone as the primary antipsychotic medication were enrolled...

Background: For long-term hospitalized patients suffering from schizophrenia, metabolic disease and hyperprolactinemia (HPRL) are common comorbidities. This article is aimed at analyzing the factors influencing comorbid type 2 diabetes mellitus (T2DM) on prolactin (PRL) levels in long-term hospitalized patients suffering from schizophrenia. Methods: This study included 378 long-term hospitalized patients with schizophrenia. Common metabolic markers and PRL levels of included samples were collected, and the severity of psychopathology was assessed using the Positive and Negative Symptoms Scale (PANSS)...

Autism spectrum disorder (ASD) is a neurodevelopmental disorder of heterogenous etiology exhibiting a challenge in understanding its exact neuro-pathophysiology. Recently, peroxisome proliferator activated receptor (PPAR)-α activation was found to play a fundamental role in neuroprotection and improving autistic-like-behaviors in experimental animal models of ASD through alleviating neuroinflammation, oxidative-stress, astrocyte reactivity, tauopathy in addition to its favorable role in metabolic regulation, thus attracting attention as a possible target in treatment of ASD...

Aripiprazole, metformin, and paeoniae-glycyrrhiza decoction (PGD) have been widely used as adjunctive treatments to reduce antipsychotic (AP)-induced hyperprolactinemia in patients with schizophrenia. However, the comparative efficacy and safety of these medications have not been previously studied. A network meta-analysis of randomized controlled trials (RCTs) was conducted to compare the efficacy and safety between aripiprazole, metformin, and PGD as adjunctive medications in reducing AP-induced hyperprolactinemia in schizophrenia...

Alzheimer's disease (AD; progressive neurodegenerative disorder) is associated with cognitive and functional impairment with accompanying neuropsychiatric symptoms. The available pharmacological treatment is of a symptomatic nature and, as such, it does not modify the cause of AD. The currently used drugs to enhance cognition include an N-methyl-d-aspartate receptor antagonist (memantine) and cholinesterase inhibitors. The PUBMED, Medical Subject Heading and Clinical Trials databases were used for searching relevant data...

Objectives: Mixed dopamine and serotonin receptor antagonists (DSRAs) are associated with significant weight gain and its complications. Our aim was to evaluate the effectiveness of metformin in reducing body mass index (BMI) and metabolic parameters in children treated with DSRAs. Methods: We report a naturalistic study of 49 children and adolescents (mean age 14.9 ± 3.7 years), with BMI >85 percentile for age, treated with DSRAs during 2018-2020 in a child psychiatry clinic. Clinical data, anthropometric measurements, and laboratory tests were compared between those who were (study group, n  = 31) and were not (control group, n  = 18) treated with metformin...

Introduction: Affecting ~1% of the world population, schizophrenia is known as one of the costliest and most burdensome diseases worldwide. Antipsychotic medications are the main treatment for schizophrenia to control psychotic symptoms and efficiently prevent new crises. However, due to poor compliance, 74% of patients with schizophrenia discontinue medication within 1.5 years, which severely affects recovery and prognosis. Through research on intra and interindividual variability based on a psychopathology-neuropsychology-neuroimage-genetics-physiology-biochemistry model, our main objective is to investigate an optimized and individualized antipsychotic-treatment regimen and precision treatment for first-episode schizophrenic patients...

RATIONALE: Second-generation antipsychotics are the first-line medications prescribed for schizophrenic patients; however, some of them, such as olanzapine and risperidone, may induce metabolic dysfunctions during short-term treatment. Metformin is an effective adjuvant that attenuates antipsychotic-induced metabolic dysfunctions (AIMD) in clinical practice. Whether metformin can reverse AIMD and whether metformin affects the therapeutic effects of antipsychotics in animal models of schizophrenia are questions that still need to be investigated...

Under the Universal Coverage Scheme (UCS) with payment per capita for outpatient (OP) services, hospitals' financial risks will rise if access to essential drugs increases. This study examined trends in access to and price of essential drugs for noncommunicable diseases (NCDs) and an overall purchasing price index (PPI) for an OP drug basket from public hospitals. To examine drug access, OP prescription data from 2010-2012 were obtained from the UCS. Access to thirteen drugs for diabetes, hypertension, and dyslipidemia was examined for trend using a time-series analysis...

INTRODUCTION:  A non-ketotic hyperglycaemia may cause an affection of basalganglia and, in the following, lead to a hemiballism-hemichorea movement-disorder. HISTORY:  A 68-year-old male patient was admitted at our ward with a subacute and painless hemichorea-hemiballism movement-disorder. FINDINGS AND DIAGNOSIS:  Due to elevated levels of glycated haemoglobin, negative ketone bodies in the urine and characteristic changes of the striatum in MR-imaging the diagnosis of a non-ketotic hyperglycemia induced hemichorea-hemiballism was made...

BACKGROUND: Weight gain is a potentially concerning side effect of second-generation antipsychotics (SGAs). Metformin, a biguanide with antihyperglycemic effects, is used to manage weight gain in adults treated with SGAs. OBJECTIVE: The objective of this study was to perform the first systematic review and meta-analysis of randomized controlled trials (RCTs) assessing the effects of metformin on weight gain in children and adolescents treated with SGAs. METHODS: Based on a pre-registered protocol (PROSPERO-CRD42017074839), we searched the PubMed, EMBASE, PsychoINFO, BIOSIS, Science Direct, Cochrane Central, and ClinicalTrials...

A 28-year-old male presented with 2 days of vomiting and abdominal pain, preceded by 2 weeks of thirst, polyuria and polydipsia. He had recently started risperidone for obsessive-compulsive disorder. He reported a high dietary sugar intake and had a strong family history of type 2 diabetes mellitus (T2DM). On admission, he was tachycardic, tachypnoeic and drowsy with a Glasgow Coma Scale (GCS) of 10/15. We noted axillary acanthosis nigricans and obesity (BMI 33.2 kg/m2 ). Dipstick urinalysis showed ketonuria and glycosuria...

PURPOSE OF REVIEW: The purpose of this manuscript is to review the evidence generated by clinical trials of pharmaceuticals in autism spectrum disorder (ASD), describe challenges in the conduct of such trials, and discuss future directions RECENT FINDINGS: Clinical trials in ASD have produced several compounds to adequately support the pharmacological treatment of associated symptom domains: attention deficit hyperactivity disorder (methylphenidate, atomoxetine, and alpha agonists), irritability/aggression (risperidone and aripiprazole), sleep (melatonin), and weight gain associated with atypical antipsychotic use (metformin)...

Psychiatric illness in the paediatric population is increasing and the weight effect of medications for these problems is often unclear. A comprehensive literature search was undertaken to identify studies reporting weight in relation to antipsychotic and antidepressant use in children and adolescents. From 636 articles, 42 were selected for review. Selective serotonin reuptake inhibitors (SSRIs) and serotonin and norepinephrine reuptake inhibitors (SNRIs) do not cause weight gain and may lead to improvements in weight status over the short, but not, long term...

CONTEXT: Various drugs affect body weight as a side effect. OBJECTIVE: We conducted this systematic review and meta-analysis to summarize the evidence about commonly prescribed drugs and their association with weight change. DATA SOURCES: MEDLINE, DARE, and the Cochrane Database of Systematic Reviews were searched to identify published systematic reviews as a source for trials. STUDY SELECTION: We included randomized trials that compared an a priori selected list of drugs to placebo and measured weight change...

OBJECTIVE: There is general consensus that second-generation antipsychotics are at least as effective as and more tolerable than first-generation antipsychotics. We address questions of safety and tolerability in both the short-term and long-term use of these medications by reviewing the existing literature in youth and adults. DATA SOURCES: A MEDLINE search was conducted via PubMed using the following keywords (in various combinations): typical antipsychotics, atypical antipsychotics, children, adolescents, side effects, weight gain, diabetes, metformin, metabolic syndrome, and CATIE...

Second-generation antipsychotics (SGAPs) and second-generation antidepressants (SGADs) have multiple US Food and Drug Administration-approved indications and are frequently prescribed by primary care physicians. We review the relative potential of these drugs to cause weight gain and glucose dysregulation, and offer clinical guidance to minimize and manage this risk. Among SGAPs, clozapine and olanzapine have a high risk for causing weight gain and glucose dysregulation; iloperidone, paliperidone, quetiapine, and risperidone have a medium risk; and aripiprazole, asenapine, lurasidone, and ziprasidone have a low risk...
