BACKGROUND: The aim of this observational study was to investigate the relationship between metabolic factors and use of selective serotonin reuptake inhibitors (SSRIs) combined with olanzapine, quetiapine or risperidone. METHODS: Data from the Norwegian Thematically Organized Psychosis study, a cross-sectional study on 1301 patients with schizophrenia (n=868) or bipolar disorder (n=433), were analyzed. As exposure variables in the linear regression model were included the dose or serum concentration of SSRIs (n=280) and of olanzapine (n=398), quetiapine (n=234) or risperidone (n=128)...

Dextromethorphan (3-methoxy-N-methylmorphinan), also known as "DXM" and "the poor man's PCP," is a synthetically produced drug that is available in more than 140 over-the-counter cough and cold preparations. Dextromethorphan (DXM) has overtaken codeine as the most widely used cough suppressant due to its availability, efficacy, and safety profile at directed doses. However, DXM is subject to abuse. When consumed at inappropriately high doses (over 1500 mg/day), DXM can induce a state of psychosis characterized by Phencyclidine (PCP)-like psychological symptoms, including delusions, hallucinations, and paranoia...

Obsessive-compulsive disorder (OCD) is a chronic, distressing and substantially impairing neuropsychiatric disorder, characterized by obsessions or compulsions. The current case describes a 44-year-old adult female diagnosed with OCD. The patient had an incomplete response to several SSRIs alone during her past treatment, and led a poor-quality life for at least three years. Current multidimensional approaches, including combined cognitive behavioral therapy (CBT) and the Selective Serotonin Reuptake Inhibitor (SSRI, Sertraline) with a small dose of antipsychotics (Aripiprazole) for augmentation, as well as familial support and resources from the internet were provided for the patient for six months...

BACKGROUND AND AIMS: Central neuromodulators (antidepressants, antipsychotics and other CNS targeted medications) are increasingly used for treatment of functional GI disorders (FGIDs), now recognized as disorders of gut-brain interaction. However, the available evidence and guidance for the use of central neuromodulators in these conditions is scanty and incomplete. In this Rome Foundation Working Team report, a multidisciplinary team summarized available research evidence and clinical experience to provide guidance and treatment recommendations...

OBJECTIVES: The aim of our study was to examine the association between ABCB1 polymorphisms G2677T/A (rs2032582) and C3435T (rs1045642) and common CYP2D6 variants, with the response to antipsychotic treatment of psychotic patients, in a naturalistic setting, in Greece. METHODS: One hundred patients suffering from schizophrenia and other psychotic disorders were included in the study. Dosages were normalized to chlorpromazine equivalents. Response following 1 month of treatment was assessed as either a continuous variable, using the distribution of the corrected Positive and Negative Syndrome Scale percent change, or as a dichotomous variable defined as the number of patients scoring ≥30% from the corrected baseline Positive and Negative Syndrome Scale score...

Oscillatory activity in the gamma frequency range is a critical mechanism, which integrates neural networks within and across brain structures during cognitive processes. In schizophrenia, abnormalities in high gamma oscillations are ubiquitous and most likely reflect dysfunction in neuronal networks. In conscious rats, disturbed network oscillations associated with positive symptoms and cognitive deficits were modeled in different cortical areas by the dopaminergic agonist (amphetamine) and the N-methyl-D-aspartate (NMDA) receptor antagonists (PCP and MK801)...

Depression is a nosological entity which may appear alone or concomitantly (e.g. in schizophrenia). Analysis of data from both clinical and experimental studies allows a conclusion that atypical antipsychotics, such as aripiprazole (ARI), may also be effective in treating depression in addition to antidepressants. The aim of the studies was to determine antidepressant efficacy of ARI, venlafaxine (VEN) and combined therapy using both drugs, in prenatally stressed rats (animal depression model) and control group...

Oppositional defiant disorder (ODD) is diagnosed broadly on the basis of frequent and persistent angry or irritable mood, argumentativeness/defiance, and vindictiveness. Since its inception in the third Diagnostic and Statistical Manual of Mental Disorders, epidemiological and longitudinal studies have strongly suggested a distinct existence of ODD that is different from other closely related externalizing disorders, with different course and outcome and possibly discrete subtypes. However, several issues, such as symptom threshold, dimensional versus categorical conceptualization, and sex-specific symptoms, are yet to be addressed...

BACKGROUND: Acute psychotic illness, especially when associated with agitated or violent behaviour, can require urgent pharmacological tranquillisation or sedation. In several countries, clinicians often use benzodiazepines (either alone or in combination with antipsychotics) for this outcome. OBJECTIVES: To examine whether benzodiazepines, alone or in combination with other pharmacological agents, is an effective treatment for psychosis-induced aggression or agitation when compared with placebo, other pharmacological agents (alone or in combination) or non-pharmacological approaches...

The combination of qualitative and quantitative bimonthly analysis of pharmaceuticals and illicit drugs using liquid chromatography coupled to mass spectrometry is presented. A liquid chromatography-quadrupole time of flight instrument equipped with Sequential Window Acquisition of all THeoretical fragment-ion spectra (SWATH) was used to qualitatively screen 346 compounds in influent wastewater from two wastewater treatment plants in South Australia over a 14-month period. A total of 100 compounds were confirmed and/or detected using this strategy, with 61 confirmed in all samples including antidepressants (amitriptyline, dothiepin, doxepin), antipsychotics (amisulpride, clozapine), illicit drugs (cocaine, methamphetamine, amphetamine, 3,4-methylenedioxymethamphetamine (MDMA)), and known drug adulterants (lidocaine and tetramisole)...

Antipsychotics play a key role in the pharmacological treatment of schizophrenia, and monotherapy is effective for most patients. Achieving an optimal treatment response is, however, often difficult. Combining an antidepressant drug to the antipsychotic regimen could potentially improve treatment outcomes, although the evidence supporting the use of such combinations is limited and contradictory. Positive evidence has mostly been obtained from the efficacy of antidepressants acting on monoamine receptors on the negative symptoms of schizophrenia...

This study assesses the risks and benefits of switching from two to one antipsychotic among participants on two non-clozapine oral antipsychotics, and among those on combinations involving either clozapine or an injectable antipsychotic. Ninety adult participants with schizophrenia or schizoaffective disorder were assigned to stay on polypharmacy or to switch to monotherapy. Half of these participants were receiving combinations of non-clozapine oral antipsychotics and half were receiving combinations involving either clozapine or an injectable antipsychotic...

OBJECTIVE: Psychotic symptoms are a common feature in Alzheimer disease (AD), occurring in approximately 40% of patients. These symptoms are associated with worse clinical outcomes. Comparatively little research, however, has distinguished delusions and hallucinations, which may have distinct clinical, neuropathological, and genetic correlates. To address this, the current study examined the clinical outcomes associated with delusions and hallucinations in AD. DESIGN: Three-year observational study...

Bipolar disorder is a debilitating illness that often leads to functional impairment when untreated. Monotherapy with mood stabilizers is preferable, although combination therapy may be necessary in refractory cases. Most studies focus on the use of lithium, anticonvulsants, and second-generation antipsychotics in the treatment of acute manic or depressive phases, as well as maintaining adequate response after the episode. More research is needed in the area of psychopharmacology of pediatric bipolar disorder to bridge the gap between clinical needs and the available data...
