Schizophrenia is a severe syndrome that affects about 1% of the world population. Since the mid-1950s, antipsychotics have been used to treat schizophrenia with preference for treating positive symptoms; however, their tolerance level is low, there are numerous side effects, and only some patients respond to the treatment. Antipsychotic medications that are more effective, better tolerated, and with fewer adverse effects are urgently needed. Given the accumulating evidence of the role filled by the ErbB signaling network in the biology of the dopamine, GABA, and glutamate systems, and in the etiology of schizophrenia, we hypothesized that the ErbB network is a candidate for development of a novel agent through which various symptoms of schizophrenia and other psychiatric disorders might be treated...

BACKGROUND: The second-generation antipsychotics (SGAs) are associated with metabolic disturbances. Diabetic ketoacidosis (DKA) is a rare, but potentially fatal sign of acute glucose metabolism dysregulation, which may be associated with the use of SGAs. This study aims to review published reports of patients with schizophrenia and antipsychotic drug-associated DKA, focusing on the effective management of both conditions. METHODS: Using a predefined search strategy, we searched PubMed and EMBASE from their inception to July 2016...

BACKGROUND: Antipsychotic polypharmacy is defined as the concomitant prescribing of more than 1 antipsychotic medication for an individual patient. Despite clinical guideline recommendations, long-acting injectable antipsychotics (LAIAs) are often used together with oral antipsychotics (OAPs) to treat a variety of psychiatric illnesses. Little research exists to address this form of antipsychotic polypharmacy, and its role in therapy is poorly understood. The purpose of this evaluation was to determine the prevalence of this prescribing pattern at our facility, identify provider rationale for polypharmacy, and analyze trends...

RATIONALE: We recently introduced a new rat model of emotional hyperthermia in which a salient stimulus activates brown adipose tissue (BAT) thermogenesis and tail artery constriction. Antipsychotic drugs, both classical and second generation, act to reduce excessive assignment of salience to objects and events in the external environment. The close association between salient occurrences and increases in body temperature suggests that antipsychotic drugs may also reduce emotional hyperthermia...

Wilson disease (WD) is an autosomal genetic disorder characterized by excessive copper deposition initially in liver (hepatic variant) followed by brain (neuropsychiatric variant) and other organs such as cornea and kidney due to defect in biliary copper excretion. Predominant presentations of neuropsychiatric variant are extrapyramidal motor dysfunctions such as dystonias, Parkinsonism, choreoathetosis, tremor, and ataxias. Nonmotor symptoms (NMS) can appear before clinical disease expression and during ongoing disease process...

BACKGROUND: Prior articles paid little attention to pharmacodynamic drug interactions (DIs) between antiepileptic drugs (AEDs) and the most important psychotropic medications (antidepressants, antipsychotics, benzodiazepines and lithium) which have potential to be clinically relevant. OBJECTIVE: This article aims to provide an updated review of the potentially clinically relevant pharmacodynamic DIs between AEDs and psychotropic medications. Pharmacodynamic DIs take place directly at the site of action of a drug or indirectly by interfering with another physiological mechanism...

As the number of hospitalized and immunocompromised patients continues to rise, invasive fungal infections, such as invasive candidiasis and aspergillosis, threaten the life of millions of patients every year. The azole antifungals are currently the most prescribed drugs clinically that display broad-spectrum antifungal activity and excellent oral bioavailability. Yet, the azole antifungals have their own limitations and are unable to meet the challenges associated with increasing fungal infections and the accompanied development of resistance against azoles...

Tardive dyskinesia (TD) is a potentially disabling condition encompassing all delayed, persistent, and often irreversible abnormal involuntary movements arising in a fraction of subjects during long-term exposure to centrally acting dopamine receptor-blocking agents such as antipsychotic drugs and metoclopramide. However, the pathogenesis of TD has proved complex and remains elusive. To investigate the mechanism underlying the development of TD, we have chronically exposed 17 Cebus apella monkeys to typical (11) or atypical (6) antipsychotic drugs...

PURPOSE: Antipsychotics (APs) are commonly used to manage neuropsychiatric symptoms (NPS) in elderly patients with dementia, even though several large studies have demonstrated an association between AP treatment and increased morbidity and mortality in people with dementia. The aim of this study is to review the scientific literature of the use of AP in the elderly with dementia and to propose an algorithm to assist in decision-making regarding the withdrawal of APs. METHODS: A computerized literature search (MEDLINE: 1966 to December 2016, EMBASE: 1982 to December 2016) was used to locate relevant literature...

Currently, numerous antipsychotic agents have been developed in the area of pharmacological treatment of schizophrenia. However, the molecular mechanism underlying multi targets of antipsychotics were yet to be explored. In this study we performed a computational network analysis based on targets of antipsychotic agents. We retrieved a total of 96 targets from 56 antipsychotic agents. By expression enrichment analysis, we identified that the expressions of antipsychotic target genes were significantly enriched in liver, brain, blood and corpus striatum...

Aggressive behavior complicates the presentation of many psychiatric illnesses, and is associated with significant morbidity. Antipsychotic medications are used to treat this symptom dimension across multiple diagnoses. In this meta-analysis we sought to identify the effect size of antipsychotic medications for the treatment of reactive-impulsive aggression in adults, and identify differences across underlying diagnosis and specific agent. A search was conducted of four databases, MEDLINE, PsychINFO, Embase and the Cochrane Library to end date of August 10, 2016...

In mature neurons, low intracellular chloride level required for inhibition is maintained by the potassium-chloride co-transporter KCC2. Impairment of Cl- extrusion following KCC2 dysfunction has been involved in many CNS disorders such as seizures, neuropathic pain or spasticity after a spinal cord injury (SCI). This makes KCC2 an appealing drug target for restoring Cl-homeostasis and inhibition in pathological conditions. In the present study, we screen the Prestwick Chemical Library® and identify conventional antipsychotics phenothiazine derivatives as enhancers of KCC2 activity...

Sedative-hypnotic drugs include gamma-Aminobutyric acid (GABA)ergic agents such as benzodiazepines, barbiturates, gamma-Hydroxybutyric acid [GHB], gamma-Butyrolactone [GBL], baclofen, and ethanol. Chronic use of these substances can cause tolerance, and abrupt cessation or a reduction in the quantity of the drug can precipitate a life-threatening withdrawal syndrome. Benzodiazepines, phenobarbital, propofol, and other GABA agonists or analogues can effectively control symptoms of withdrawal from GABAergic agents...

Tardive dyskinesia (TD) remains a clinical concern for any patient who receives an antipsychotic. While the overall risk of developing TD is lower with newer antipsychotics compared to older agents, a significant number of patients who require long-term treatment will develop TD. Recently, valbenazine (brand name Ingrezza) became the first drug to be approved by the FDA specifically for the treatment of TD. In this New Drug Review, we summarize the basic pharmacology and clinical trial results for valbenazine...
