Disruption of dopamine D1/D2 receptor complex is involved in the function of haloperidol in cardiac H9c2 cells.

Haloperidol is an antipsychotic agent and acts as dopamine D2 receptor (D2R) antagonist, as a prototypical ligand of sigma1 receptors (Sig1R) and it increases expression of type 1 IP3 receptors (IP3R1). However, precise mechanism of haloperidol action on cardiomyocytes through dopaminergic signaling was not described yet. This study investigated a role of dopamine receptors in haloperidol-induced increase in IP3R1 and Sig1R, and compared physiological effect of melperone and haloperidol on basic heart param...


Effects of short- and long-term aripiprazole treatment on Group I mGluRs in the nucleus accumbens: Comparison with haloperidol.

The D2 receptor partial agonist, aripiprazole, has shown increased therapeutic efficacy for schizophrenia, autism and Tourette's syndrome compared to traditional antipsychotics such as the D2 receptor antagonist, haloperidol. Recent evidence suggests this superior profile may be associated with downstream effects on glutamatergic synapses. Group 1 metabotropic glutamate receptors (mGluRs) and their endogenous modulators, Norbin and Homer1, are regulated by D2 receptor activity, particularly within the nucle...

Gabapentin reduces haloperidol-induced vacuous chewing movements in mice.

Tardive dyskinesia (TD) is a common adverse effect observed in patients with long-term use of typical antipsychotic medications. A vacuous chewing movement (VCM) model induced by haloperidol has been used to study these abnormalities in experimental animals. The cause of TD and its treatment remain unknown, but several lines of evidence suggest that dopamine receptor supersensitivity and gamma-aminobutyric acid (GABA) insufficiency play important roles in the development of TD. This study investigated the e...


Effect of Haloperidol on Survival Among Critically Ill Adults With a High Risk of Delirium: The REDUCE Randomized Clinical Trial.

Results of studies on use of prophylactic haloperidol in critically ill adults are inconclusive, especially in patients at high risk of delirium.

Antipsychotic-induced disorders: Reported cases and prospective study on muscle biomarkers after high exposure to haloperidol.

Antipsychotic drugs are known to induce neuromuscular effects. In this study, we review 13 years (2002-2014) of antipsychotic intoxications reported by the anti-poisoning center of Algiers (APCA). The most recorded symptoms were neuromuscular/muscular disorders, of which haloperidol was the most inducer among all antipsychotics. A prospective study was conducted between December 2012 and January 2017 to evaluate muscle effects generated after intentional or accidental ingestion of haloperidol. Fifty-one p...

Lack of dopamine supersensitivity in rats after chronic administration of blonanserin: Comparison with haloperidol.

Long-term treatment with antipsychotic drugs in patients with schizophrenia can lead to dopamine supersensitivity psychosis. It is reported that repeated administration of haloperidol caused dopamine supersensitivity in rats. Blonanserin is an atypical antipsychotic drug with high affinity for dopamine D, D and serotonin receptors. In this study, we investigated whether chronic administration of blonanserin leads to dopamine supersensitivity. Following oral treatment with blonanserin (0.78mg/kg) or haloperi...

Effects of Haloperidol on Delirium in Adult Patients: A Systematic Review and Meta-analysis.

The aim of this systematic review and meta-analysis was to investigate whether or not the use of haloperidol could reduce the incidence of delirium in adult patients.

c-Fos expression in the hypothalamic paraventricular nucleus after a single treatment with a typical haloperidol and nine atypical antipsychotics: a pilot study.

The aim of the present study was to find out whether acute effect of different doses of selected antipsychotics including aripiprazole (ARI), amisulpride (AMI), asenapine (ASE), haloperidol (HAL), clozapine (CLO), risperidone (RIS), quetiapine (QUE), olanzapine (OLA), ziprasidone (ZIP), and paliperidone (PAL) may have a stimulatory impact on the c-Fos expression in the hypothalamic paraventricular nucleus (PVN) neurons.

Dopaminergic activity mediates pups' over male preference of postpartum estrous rats.

Pups have greater incentive value than males for rats during the postpartum estrus (PPE); a period when females are both maternally and sexually motivated. Mesolimbic dopaminergic system has been proposed as a general motivational circuit; however in the literature it has been more related to the control of the motivational aspects of maternal than sexual motivations of females. Therefore, we aimed to assess the effect of antagonizing dopaminergic neurotransmission of PPE females on their preference for pup...

Haloperidol attenuates Methylphenidate and Modafinil induced behavioural sensitization and cognitive enhancement.

Previous studies have demonstrated that repeated psychostimulant administration produces behavioural sensitization and cognitive tolerance. Brain dopaminergic system and the involvement of dopamine D-receptors are considered to be important in psychostimulant-induced sensitization. Study designed to compared the motor activity by using familiar and novel enviroments and cognitive effects by water maze and passive avoidance test after long term administration of methylphenidate(at the dose 0.6 mg/kg/day, 2....

Haloperidol for delirium prevention: uncertainty remains.

d-Serine administration affects nitric oxide synthase 1 adaptor protein and DISC1 expression in sex-specific manner.

Antipsychotic medications are inefficient at treating symptoms of schizophrenia (SCZ), and N-methyl d-aspartate receptor (NMDAR) agonists are potential therapeutic alternatives. As such, these agonists may act on different pathways and proteins altered in the brains of patients with SCZ than do antipsychotic medications. Here, we investigate the effects of administration of the antipsychotic haloperidol and NMDAR agonist d-serine on function and expression of three proteins that play significant roles in SC...

Involvement of dopamine D2 receptor in a single methamphetamine-induced behavioral sensitization in C57BL/6J mice.

A single exposure to drugs of abuse is sufficient to induce behavioral sensitization, which is a form of long-lasting neuroplasticity. Dopamine D2 receptors are the main receptor for antipsychotic drugs, but little is known about their role in a single methamphetamine-induced behavioral sensitization. In the present study, we examined whether typical antipsychotic haloperidol and atypical antipsychotic risperidone, both targeting dopamine D2 receptor, could prevent the methamphetamine sensitization when the...

Fluorescence-Based High-Throughput Salt Screening.

The present study reports a high-throughput screening method for the salt formation of amine-containing active pharmaceutical ingredients (APIs) based on fluorescence measurements. A free form amine API was alkynylated by a solid-vapor reaction using propargyl bromide, and a fluorescent compound was produced by a subsequent reaction using 9-azidomethylanthracene. In contrast, salts were inert to propargyl bromide; thus, no fluorescence was observed. Samples for salt screening were prepared by grinding halop...

Efficacy, Tolerability, and Safety of Blonanserin in Schizophrenia: An Updated and Extended Systematic Review and Meta-Analysis of Randomized Controlled Trials.

We conducted an updated systematic review and meta-analysis of randomized controlled trials (RCTs) comparing blonanserin with other antipsychotics (amisulpride, aripiprazole, haloperidol, paliperidone, and risperidone).

Cross-tolerance between nitric oxide synthase inhibition and atypical antipsychotics modify nicotinamide-adenine-dinucleotide phosphate-diaphorase activity in mouse lateral striatum.

Previous research indicates that the subchronic administration of NG-nitro-L-arginine (L-NOARG) produces tolerance to haloperidol-induced catalepsy in Swiss mice. The present study aimed to further investigate whether intermittent subchronic systemic administration of L-NOARG induces tolerance to the cataleptic effects of haloperidol as well as olanzapine or clozapine (Clz) in C57Bl mice after subchronic administration for 5 consecutive days. Striatal FosB protein expression was measured in an attempt to ga...

Differential behavioral and glial responses induced by dopaminergic mechanisms in the iNOS knockout mice.

The interaction between distinctive nitric oxide synthase (NOS) isoforms and the dopamine system provides new avenues to the development of pharmacological tools for the pathophysiological conditions of the dopaminergic system. Our aim was to investigate the influences of dopamine-induced effects in inducible NOS knockout (iNOS KO) mice. In order to characterize iNOS KO mice phenotype, the animals were submitted to the basal analyses of motor, sensorimotor and sensorial abilities. Pharmacological challengin...

He developed infiltrated and grouped erythematous lesions on the elbows and knees three days after commencing multiple drugs (promethazine, hal...

The differential effects of neuroleptic drugs and PACAP on the expression of BDNF mRNA and protein in a human glioblastoma cell line.

Despite numerous studies, the molecular mechanisms underpinning the action of antipsychotic drugs remain not fully understood. It has been suggested that, in addition to the modulation of monoaminergic neurotransmission, antipsychotic drugs can also affect the expression of neurotrophic factors in the brain. The present study examines the effects of a first-generation neuroleptic drug (FGA; haloperidol) and two second-generation neuroleptic drugs (SGAs; olanzapine and amisulpride) on the expression and leve...

Assessing the critical issues of atypical antipsychotics in schizophrenic inpatients.

Antipsychotics are effective in reducing positive and disorganization symptoms of schizophrenia. Although SGAs initially all were believed to be more efficacious and tolerable than FGAs, several data show that the SGAs are no more effective than FGAs. In clinical practice, frequent switching of antipsychotic medications is widespread for lack of efficacy, adverse side effects, and partial or not-compliance response. This study suggested that most clinically stable inpatients with schizophrenia maintain thei...

Relation of inflammatory markers with symptoms of psychotic disorders: a large cohort study.

Immunological mechanisms may play a role in symptomatology of patients with a psychotic disorder. Besides metabolic problems and medication use, inflammatory processes that may occur due to the disorder may cause increased inflammatory markers and concurrent psychiatric symptoms. The aim of this study is to investigate whether levels of C-reactive protein (CRP) and white blood cell count (WBC) are related to positive and negative symptoms of psychotic disorders, and whether age, gender, duration of illness,...
