The first-line treatment for psychotic disorders remains antipsychotic drugs with receptor antagonist properties at D2-like dopamine receptors. However, long-term administration of antipsychotics can upregulate D2 receptors and produce receptor supersensitivity manifested by behavioral supersensitivity to dopamine stimulation in animals, and movement disorders and supersensitivity psychosis (SP) in patients. Antipsychotic-induced SP was first described as the emergence of psychotic symptoms with tardive dyskinesia (TD) and a fall in prolactin levels following drug discontinuation...

OBJECTIVE: Antipsychotic drug sensitivity in very late-onset schizophrenia-like psychosis (VLOSLP) is well documented, but poorly understood. This study aimed to investigate blood drug concentration, D2/3 receptor occupancy and outcome in VLOSLP during open amisulpride prescribing, and compare this with Alzheimer's disease (AD). METHODS: Blood drug concentration, prolactin, symptoms and extrapyramidal side-effects (EPS) were serially assessed during dose titration...

Imbalance in neural excitation and inhibition is associated with behavioral dysfunction in individuals with schizophrenia and at risk for this illness. We examined whether targeting increased neural activity with the antiepileptic agent, levetiracetam, would benefit memory performance in a preclinical model of schizophrenia that has been shown to exhibit hyperactivity in the hippocampus. Adult rats exposed to ketamine subchronically during late adolescence showed impaired hippocampal-dependent memory performance...

Since the middle of the 19th century, both neurologists and psychiatrists have linked psychosis and epilepsy. Clozapine, the most effective antipsychotic drug, alters electroencephalographic activity and carries a significant risk of causing seizures. Unfortunately, this risk limits the drug's potential use in treating pharmacoresistant psychosis in patients with epilepsy. We present a unique case in which we used clozapine successfully as a last resort treatment for chronic interictal psychosis in a 43-year-old woman with severe pharmacoresistant epilepsy and recurrent status epilepticus...

Glucocorticosteroids (CS) play a key role in the treatment of numerous diseases. Nonetheless, they can be accompanied by several adverse effects. We present the case of a 51-year-old woman who was treated with high-dose CS for a relapse of her multiple sclerosis. After 5 days of treatment, the patient developed severe diabetic ketoacidosis, hypertriglyceridemia and acute pancreatitis-a potentially life-threatening triad which has previously been described, in our case, however, for the first time as a complication of CS therapy...

The purpose of this nationwide population-based study is to compare the long-term effectiveness of brand-name antipsychotics with generic antipsychotics for treating schizophrenia. We identified patients with schizophrenia who were prescribed antipsychotics from a random sample of one million records from Taiwan's National Health Insurance database, observed between January 1, 2000 and December 31, 2012. Only those with no prior use of antipsychotics for at least 180days were included. We selected patients who were prescribed brand-name risperidone (N=404), generic risperidone (N=145), brand-name sulpiride (N=334), or generic sulpiride (N=991)...

BACKGROUND: Recently, several clinical studies have suggested a beneficial effect of a combination of antidepressants (ADs) with antipsychotic drugs in drug-resistant depression. Moreover, preclinical and clinical studies indicated a role of brain-derived neurotrophic factor (BDNF) in the pathology of depression, as well as in the mechanism of action of ADs. METHODS: In the present study, we investigated the effect of repeated administration of ADs, escitalopram, fluoxetine or mirtazapine and a low dose of risperidone (an atypical antipsychotic drug) given separately or in combination, on the mRNA and protein levels of BDNF or cAMP response element binding (p-CREB) in the hippocampus and frontal cortex of male Wistar rats...

INTRODUCTION: Clozapine is the preferred antipsychotic for treatment-resistant schizophrenia, but has significant adverse effects, including gastrointestinal hypomotility or 'slow gut', which may result in severe constipation, ileus, bowel obstruction, and even death. These gastrointestinal effects remain inadequately recognized. METHODS: We reviewed all reports of serious clozapine-induced gastrointestinal hypomotility (CIGH) submitted to the Australian Therapeutic Goods Administration and New Zealand Pharmacovigilance Centre between 1992 and 2013...

PURPOSE: The antipsychotic agent quetiapine was introduced in Norway in 2003. We have assessed changes in dispensed prescriptions, including dosing, of quetiapine in Norway from 2004 to 2015. METHODS: Data on the sales of antipsychotics and antidepressants were drawn from the Norwegian Prescription Database. A total of 47,474 outpatients filled 195,622 prescriptions of quetiapine. Reimbursement codes, use of antipsychotics or antidepressants 12 months prior to the first prescription of quetiapine and estimated mean volume used measured as defined daily doses (DDDs) per day were used as proxies for diagnoses...

High doses of antipsychotics have been associated with loss in cortical and total gray matter in schizophrenia. However, previous imaging studies have not taken benzodiazepine use into account, in spite of evidence suggesting adverse effects such as cognitive impairment and increased mortality. In this Northern Finland Birth Cohort 1966 study, 69 controls and 38 individuals with schizophrenia underwent brain MRI at the ages of 34 and 43 years. At baseline, the average illness duration was over 10 years. Brain structures were delineated using an automated volumetry system, volBrain, and medication data on cumulative antipsychotic and benzodiazepine doses were collected using medical records and interviews...

Charles Bonnet Syndrome (CBS) is a common cause of visual hallucinations seen in elderly people with visual impairment. Well-formed visual hallucinations in clear consciousness with preserved insight are commonly reported in literature. We report a case of CBS having multisensory hallucinations. An elderly patient with visual impairment fulfilling the criteria of CBS presents with various modalities of hallucinations viz. visual, auditory and tactile hallucinations improved completely with low dose of antipsychotics...

Julia Korell, Bruce Green, Bart Remmerie, An Vermeulen
Schizophrenia is a common disease managed by a range of interventions with the primary treatment being antipsychotic medications (APS). Inadequate response, lack of adherence, and/or adverse events often prevent optimal therapeutic effects or therapeutic efficiency. Monitoring APS plasma concentrations can be used together with a full clinical evaluation to help improve patient care or offer better treatment options for the patient. To enable interpretation of individual risperidone and paliperidone plasma concentrations, we developed 'reference ranges', which consider the expected variability in plasma concentrations between subjects across the population, rather than representing a 'therapeutic range' that relates to efficacy and/or safety outcomes...

Selvizhi Subramanian, Birgit A Völlm, Nick Huband
BACKGROUND: Schizophrenia and related disorders such as schizophreniform and schizoaffective disorder are serious mental illnesses characterised by profound disruptions in thinking and speech, emotional processes, behaviour and sense of self. Clozapine is useful in the treatment of schizophrenia and related disorders, particularly when other antipsychotic medications have failed. It improves positive symptoms (such as delusions and hallucinations) and negative symptoms (such as withdrawal and poverty of speech)...

BACKGROUND: Atypical antipsychotic agents (AAP) alleviate the symptoms of severe mental health disorders, such as schizophrenia, by antagonizing dopamine and serotonin receptors. Recently, AAP have also been shown to exhibit immunomodulatory properties in the central nervous system (CNS). OBJECTIVE: Building on research which demonstrated the ability of the AAP risperidone and clozapine to modify the disease course of experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis (MS), we aimed to more fully investigate the potential of clozapine as a possible treatment for MS...
