INTRODUCTION In critically ill patients, delirium is a serious and frequent disorder that is associated with a prolonged intensive care and hospital stay and an increased morbidity and mortality. Without the use of a delirium screening instrument, delirium is often missed by ICU nurses and physicians. The effects of implementation of a screening method on haloperidol use is not known. The purpo...
Objective: The current study was planned to evaluate the antiasthamatic effect of Electrohomeopathic medicine Pettorale in various experimental models.
 Methods: antiasthmatic activity studied on different animals like histamine induced bronchospasm guinea pig, haloperidol catalepsy rats, egg albumin paw anaphylaxis rats and milk leukocytosis mice.
 Conclusion: Preliminary phytochemic...
First- and second-generation antipsychotics (FGAs and SGAs, respectively), have the ability to inhibit cholesterol biosynthesis and also to interrupt the intracellular cholesterol trafficking, interfering with low-density lipoprotein (LDL)-derived cholesterol egress from late endosomes/lysosomes. In the present work, we examined the effects of FGA haloperidol on the functionality of late endoso...
The acute and subchronic effects of a variety of doses of a prototype typical (haloperidol) or one of several atypical antipsychotic drugs (clozapine, olanzapine, risperidone, quetiapine, or sertindole) on regional brain neurotensin (NT) tissue concentrations, and NT receptor binding were examined. Acute administration of haloperidol, clozapine, olanzapine, and risperidone dose-dependently incr...
Antipsychotics are the mainstay for the treatment of schizophrenia. Although these drugs act at several neurotransmitter receptors, they are expected to elicit different neuroadaptive changes at structures relevant for schizophrenia. Because glutamatergic dysfunction plays a role in the pathophysiology of schizophrenia, we focused our analysis on glutamatergic neurotransmission after repeated t...
The fact that chronic administration of typical and atypical antipsychotic drugs is required for optimal therapeutic response suggests that drug-induced adaptive neurochemical changes contribute to their mechanism of action. In the present study, the effects of chronic and acute haloperidol and olanzapine were compared on ketamine-induced activation of select brain regions, as reflected by alte...
Antipsychotic drugs at noncataleptic doses selectively suppress conditioned avoidance response in rats. In our previous study, we had used a two-way active avoidance response paradigm to show that the antipsychotic-induced interoceptive state is one of the mechanisms underlying the avoidance-disruptive effect of antipsychotics. In this study, we sought to further examine this mechanism using a ...
Antagonism of the discriminative stimulus properties of 10 mglkg cocaine was studied in rats by use of the dopamine Dl antagonist SCH 23390 and the Dl antagonist haloperidol. Whereas SCH 23390 and haloperidol were by themselves unable to antagonize the cueing properties of cocaine, the combination of both dopamine antagonists resulted in a complete blockade of the cocaine cue. In the presence o...
Serum haloperidol and serum dopamine blocking activity were measured, and steady state levels were compared in 22 chronic male schizophrenic patients. Haloperidol levels were measured by high pressure liquid chromatography (HPLC), and dopamine blocking activity was measured by a radioreceptor assay (NRRA). Clinical status was determined by the Brief Psychiatric Rating Scale (BPRS) and the Abnor...
BACKGROUND Three studies compared olanzapine and haloperidol given orally in maintenance therapy for schizophrenia and related psychoses. METHOD Data were from double-blind extensions of acute studies. The subjects met criteria for schizophrenia, schizophreniform disorder or schizoaffective disorder. Subjects had responded to acute therapy (Brief Psychiatric Rating Scale total score decreased...
