Quetiapine, an atypical antipsychotic, has been employed to treat alcoholic patients with comorbid psychopathology. It was shown to scavenge hydroxyl radicals and to protect cultured cells from noxious effects of oxidative stress, a pathophysiological mechanism involved in the toxicity of alcohol. This study compared the redox status of the liver and the brain regions of prefrontal cortex, hipp...

We report the case of a patient who presented with coma in the context of baclofen and quetiapine overdose. While the clinical picture was largely in keeping with previous descriptions of baclofen and quetiapine toxicity, the patient went on to exhibit clinical and biochemical features of cranial diabetes insipidus, a finding which has not previously been described in this context.

Serotonergic medications are used for the prevention and treatment of depression during pregnancy. Selective serotonin reuptake inhibitors serotonin-norepinephrine (SNRIs) can cause poor neonatal adaptation, which has been attributed to withdrawal versus toxicity. Bupropion, a norepinephrine-dopamine inhibitor, is often as an adjunctive agent selective or SNRIs refractory depression. Quetiapine...

Introduction: Quetiapine (‘Seroquel’) is an established treatment for schizophrenia currently approved at doses up to 750 mg/day (800 mg/day in the USA); however, some patients may benefit from treatment with higher doses. Methods: This open-label study of 35 hospitalised patients with schizophrenia, schizoaffective disorder, bipolar disorder or alcoholinduced psychosis investigated the efficac...

PURPOSE We aimed to determine which antipsychotic is most effective for the treatment of acute schizophrenia with catatonic stupor. PATIENTS AND METHODS Data were obtained from the medical records of 450 patients with the diagnosis of schizophrenia, who had received acute psychiatric inpatient treatment between January 2008 and December 2010 at our hospital. Among them, 39 patients (8.7%) met...

We previously reported that treatment with 160mg/d of lurasidone improved cognitive performance in a manner superior to placebo, quetiapine XR 600mg/d, and lurasidone 80mg/d, based on a 6-week randomized trial of patients with an acute exacerbation of schizophrenia. The objective of this post-hoc analysis was to explore the cognitive and functional performance of patients whose final doses of l...

OBJECTIVE This study was undertaken in the belief that the atypical antipsychotic drug quetiapine could prevent apoptosis in the penumbra region following ischemia, taking into account findings that show 5-hydroxytryptamine-2 receptor blockers can prevent apoptosis. METHODS We created 5 groups, each containing 6 animals. Nothing was done on the K-I group used for comparisons with the other gr...

The atypical antipsychotics were believed to induce less extrapyramidal syndrome, including tardive dyskinesia (TD). Since the introduction of the quetiapine, it is also reported with less TD side effects. It even can relieve the symptoms of severe TD and reduce the risk of TD. The quetiapine's low affinity and fast dissociation from postsynaptic dopamine D2 receptors should give the least risk...

BACKGROUND Although the benefits of antipsychotic pharmacotherapy can be pronounced, many patients develop unwanted adverse effects including a variety of movement disorders. Compared with the traditional antipsychotics, the atypical antipsychotics have a decreased risk for associated movement disorders. Drug-induced movement disorders can occur, however, and the risk of adverse events can incr...

BACKGROUND Nocturnal enuresis has been reported in patients taking clozapine, but the incidence has not been accurately established. The incidence of enuresis in patients taking risperidone, olanzapine or quetiapine is unknown. Aims To compare nocturnal enuresis in patients taking clozapine with that in patients taking risperidone, olanzapine or quetiapine. METHOD Observational cohort study u...
