The monoamine stabilizer (3S)-3-[3-(methenesulfonyl)phenyl]-1-propylpiperidine hidrochloride [(-)-OSU6162] is a promising compound for the treatment of neurological and psychiatric disorders, such as schizophrenia. Here, we tested the hypothesis that (-)-OSU6162 prevents hyperlocomotion and sensorimotor deficits in prepulse inhibition of the startle response (PPI) induced by psychomimetic drugs. Male Swiss mice received injections of (-)-OSU6162 (1, 3, 10, or 30 mg/kg), and their motor responses were investigated in the open field and in the catalepsy tests, which predicts liability to induce sedation and extrapyramidal side effects, respectively...

Angioedema has recently been reported as a side effect associated with the antipsychotic risperidone. We report a case of dystonia with concurrent angioedema due to risperidone. A 40-year-old male with a history of schizophrenia was started on 3 mg of risperidone BID and developed perioral and periorbital edema along with increased muscle rigidity and hand tremor within 24 h of initial administration. His symptoms abated after cessation of risperidone and intravenous administration of corticosteroids and antihistamine...

Akathisia is a common and distressing neuropsychiatric syndrome associated with antipsychotic medication, characterised by subjective and objective psychomotor restlessness. The goal of this guideline is to provide clinicians with recommendations on the assessment and treatment of akathisia. We performed a systematic review of therapeutic studies assessing the treatment of antipsychotic-induced extrapyramidal symptoms. Forty studies on akathisia and 4 systematic reviews evaluating the adverse effects of antipsychotics were used in the formulation of recommendations...

Depression is common in patients with schizophrenia and associated with serious consequences. However, previous studies have mixed findings on characteristics of depression in schizophrenia, partly because of the use of depressive symptom scales that are not specific to schizophrenia. This study examined the prevalence and correlates of depressive symptoms in Chinese patients with schizophrenia. A consecutive sample of 349 male inpatients with schizophrenia was recruited from the largest psychiatric specialty hospital in south-central China...

Background: Clozapine is the antipsychotic of choice for treatment-resistant schizophrenia and has minimal risk for extrapyramidal symptoms. Therapeutic benefits, however, are accompanied by a myriad of cardiometabolic side-effects. The specific reasons for clozapine's high propensity to cause adverse cardiometabolic events remain unknown, but it is believed that autonomic dysfunction may play a role in many of these. Objective: This systematic review summarizes the literature on autonomic dysfunction and related cardiovascular side effects associated with clozapine treatment...

Although recent studies focused on traditional Chinese medicine (TCM) for the treatment of refractory schizophrenia have reported that it may be beneficial, there is still lack of convincing evidence and critical meta-analytic work regarding its effectiveness as an adjunctive therapy. Therefore, we performed a meta-analysis to investigate the effectiveness of TCM in combination with antipsychotics for refractory schizophrenia. Fourteen articles involving 1725 patients published as of December 2016 were included which compared antipsychotic therapies to either TCM alone, or TCM as an adjunctive therapy...

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 gain further insights into striatal mechanisms in antipsychotic-induced extrapyramidal symptoms side effects...

In the search for efficacious pharmacotherapies to treat cocaine addiction much attention has been given to agents targeting dopamine D1 or D3 receptors because of the involvement of these receptors in drug-related behaviors. D1-like and D3 receptor partial agonists and antagonists have been shown to reduce drug reward, reinstatement of drug seeking and conditioned place preference (CPP) in rodents and non-human primates. However, translation of these encouraging results to clinical settings has been limited due to a number of factors including toxicity, poor pharmacokinetic properties and extrapyramidal and sedative side effects...

Parkinson's disease (PD) is a progressive neurodegenerative motor disorder characterized by the degeneration of dopaminergic nigrostriatal neurons. Levodopa (L-DOPA) is the most effective therapy for PD, however, PD progression continues with significant side effects in long term, thus necessitating the search for effective therapy that impedes PD progression. PD therapy through non-dopaminergic pathways offers treatment without the risk of extrapyramidal effects. In this regard, earlier, we had reported, a novel compound IDPU with potential adenosine A2A receptor antagonist effect in haloperidol (chronic treatment) induced Parkinson model...

Antipsychotic drugs are the mainstay of psychotic disorders. The 'typical' antipsychotic agents are commonly employed for the positive symptoms of schizophrenia, though at an expense of extrapyramidal side effects (EPS). In the present study, we employed haloperidol (HP)-induced catalepsy model in mice to evaluate the role of adenosine receptor antagonist and cyclooxygenase (COX) enzyme inhibitor in the amelioration of EPS. HP produced a full blown catalepsy, akinesia and a significant impairment in locomotion and antioxidant status...

Objective: Till date, typical antipsychotic haloperidol is the treatment of choice for delirium. But, due to higher side effects with haloperidol, newer atypical antipsychotics (e.g., olanzapine) are increasingly being used in the treatment of delirious patients. The aim of the current research was to study the efficacy and tolerability of haloperidol and olanzapine in the treatment of delirium. Materials and Methods: This was an open-label, randomized controlled study carried out in a tertiary care hospital at Chandigarh, India...

BACKGROUND: The long-term effects of dose reduction of atypical antipsychotics on cognitive function and symptomatology in stable patients with schizophrenia remain unclear. We sought to determine the change in cognitive function and symptomatology after reducing risperidone or olanzapine dosage in stable schizophrenic patients. METHODS: Seventy-five stabilized schizophrenic patients prescribed risperidone (≥4 mg/day) or olanzapine (≥10 mg/day) were randomly divided into a dose-reduction group ( n=37) and a maintenance group ( n=38)...

Prochlorperazine is a phenothiazine-class antipsychotic drug usually used to treat nausea, vomiting and schizophrenia. Phenothiazine derivatives have been known to cause serious side effects, like extrapyramidal symptoms, but also skin disorders which mechanism has not been fully established. The aim of this study was to examine the interaction between prochlorperazine and melanin as well as to estimate the effect of prochlorperazine on cell viability, melanogenesis and antioxidant defense system in normal human melanocytes...

Neuroleptic malignant syndrome (NMS) is a severe motor syndrome occurring as a consequence of neuroleptic treatment. We present a case of a 67-year-old Caucasian woman with a history of a major depressive disorder with psychotic features. During her third hospital admission, symptoms of autonomic instability, hyperpyrexia, severe extrapyramidal side effects, and delirium appeared, suggesting NMS due to concomitant treatment with risperidone and quetiapine, among other drugs. Despite several consecutive pharmacological treatments (lorazepam, bromocriptine and amantadine) and prompt initiation of electroconvulsive therapy (ECT), clinical improvement was observed only after combining bupropion with ECT...

The paper presents an overview and analysis of the results of research on therapeutic ranges of concentrations and receptor occupancy, mainly D2 receptors, in the treatment with some atypical antipsychotic drugs. Amisulpride, aripiprazole, clozapine, quetiapine, olanzapine, risperidone, paliperidone, sertindole, and ziprasidone were taken into account. The benefits of therapeutic drug monitoring to optimize the effectiveness of treatment and avoid side effects or toxicity were shown. The safety of patients, with the possibility to use the lowest effective dose, is an undoubted profit of TDM...

Since l-carnosine has shown effectiveness in improvement of cognition in patients with schizophrenia, this 8-week, randomized, double-blind, placebo-controlled pilot study was conducted. Sixty-three patients with chronic schizophrenia, who were clinically stable on a stable dose of risperidone, entered the study. The patients were randomly assigned to l-carnosine (2 gr/day in two divided doses) or placebo for eight weeks. The patients were assessed using the positive and negative syndrome scale (PANSS), extrapyramidal symptom rating scale (ESRS), and Hamilton depression rating scale (HDRS) during the study course...

Schizophrenia is a heterogenous and severe neuropsychiatric disorder that affects nearly 1% of the population worldwide. Antipsychotic drugs are the mainstay of treatment, but not all patients with schizophrenia respond to treatment with these agents. Clozapine, the first atypical antipsychotic, is a highly effective medication for patients with schizophrenia who do not respond to other antipsychotics. Although clozapine tends not to produce extrapyramidal symptoms, other side effects of the drug (e.g., agranulocytosis, myocarditis, seizures) limit its widespread use...
