Filter by:This pilot trial in Finland is designed to evaluate in a randomized fashion change of agitation in acute schizophrenic patients (Schizophrenia or Schizoaffective psychosis or Schizophreniformic psychosis)Diagnostic and Statistical Manual (DSM - IV) with the first visits on days 1, 2, 4 or 5 and 7 ± 1.
The primary purpose of the study is to evaluate the efficacy of bifeprunox in the maintenance phase of schizophrenia compared to placebo.
The purpose of this study is to compare the safety of ziprasidone and risperidone for the treatment of chronic schizophrenia. The primary purpose is to differentiate the effects of ziprasidone and risperidone on extrapyramidal side effects and the secondary purpose is to compare their tolerability and efficacy.
The purpose of this study is to evaluate the efficacy and safety of ziprasidone in acute exacerbation of schizophrenia or schizoaffective disorder, including patients with recent onset of symptoms
This study aims to investigate whether the atypical antipsychotic and mixed 5-HT2/D2 antagonist sertindole modulates or improves both subcortical and cortical information processing in schizophrenic patients who had not or insufficiently responded to previous antipsychotic medication. This goal shall be accomplished by investigating the effect of sertindole of both prepulse inhibition of the acoustic startle (PPI) and P50 suppression of auditory evoked potentials in schizophrenic patients. These effects shall be compared to the effect of risperidone and shall also be compared to untreated healthy controls.
This is a randomized, inpatient, ascending multiple dose study to assess safety and tolerability of SLV-313 SR tablets administered orally to subjects with schizophrenia and schizoaffective disorder.
Purpose of this non-interventional study (NIS) is to assess the effect of the participation in an integrated care program on treatment outcomes in patients treated with Seroquel for schizophrenia.
The overall purpose of this study is to determine whether the cholesterol-lowering drug simvastatin is effective in the treatment of symptoms of schizophrenia. The primary hypothesis is that patients with schizophrenia receiving add-on treatment with simvastatin will improve clinically (as measured mainly by symptom severity) compared with patients receiving placebo, and that this improvement will be accompanied by concomitant reduction in peripheral inflammatory markers.
Many patients with schizophrenia and schizoaffective disorder have symptoms that persist, including hallucinations or delusions, despite adequate pharmacotherapy with antipsychotic drug. Glutamate is a major excitatory neurotransmitter in the brain that has been implicated in several brain diseases. NMDA antagonist drugs cause symptoms of psychosis in otherwise normal persons. It is postulated that reduced NMDA receptor mediated neurotransmission leads to an increase in synaptic glutamate. Excessive synaptic concentrations of glutamate can produce excitatory neurotoxicity. Agents which reduce excess glutamate activity are neuroprotective. This therapeutic strategy has been applied to schizophrenia through the use of compounds that reduce presynaptic release of glutamate or otherwise decrease excessive postsynaptic stimulation, including lamotrigine, memantine and a m-GLU-R2 agonist (LY354740) with the hypothesized result of a reduction in psychotic symptoms. Recently it was shown that a commonly available antibiotic (ceftriaxone) has the unique neuroprotective function of decreasing the amount of extracellular glutamate in nervous system tissue by increasing the number of glutamate transporter proteins. Our clinical experience with patients who have refractory psychosis and past Lyme disease indicates that in some patients psychosis may improve with IV ceftriaxone therapy. Whether this improvement was due to its antimicrobial or glutamate effect or a placebo effect is uncertain. In a placebo-controlled design, this study investigates the ability of ceftriaxone to decrease psychotic symptoms in patients with refractory psychotic disorders. In addition, the study will examine glutamatergic functional activity before and after treatment using brain imaging with magnetic resonance spectroscopy.
Randomized, inpatient, ascending multiple dose study given to subjects with schizophrenia and schizoaffective disorder to assess safety and tolerability.
