The aim of this case study is to review the literature and report the first published case of olanzapine-induced acute pancreatitis in New Zealand. A case report of acute pancreatitis with new onset diabetes mellitus secondary to olanzapine in a 42-year-old male, in the absence of medical risk factors is reported. Eleven previous case reports of olanzapine induced acute-pancreatitis were identi...

In the present study was examined the effect of treatment with olanzapine or risperidone, given separately or in combination with fluoxetine, in the elevated plus-maze test (an animal model of anxiety) in male Wistar rats. The obtained results showed that treatment with olanzapine (1 mg/kg), risperidone (0.1 and 0.3 mg/kg) or fluoxetine (5 and 10 mg/kg) induced an anxiolytic-like effect in the ...

UNLABELLED Although there only have been a limited number of double-blind, placebo controlled trials, antipsychotics are considered to be effective drugs for the treatment of tics in Gilles de la Tourette syndrome (GTS). Evidence concerning the efficacy of olanzapine and other atypical antipsychotics in the treatment of tics in GTS is growing, but still limited. Little is known about the use of...

The antipsychotic drug olanzapine is widely prescribed to treat schizophrenia and other psychotic disorders. However, it often causes unwanted side effects, including diabetes, due to disruption of insulin-dependant glucose metabolism through a mechanism yet to be elucidated. To determine if olanzapine can affect the first step in glucose metabolism - glucose transport inside cells - we investi...

The second-generation antipsychotic olanzapine is effective in reducing psychotic symptoms but can cause extreme weight gain in human patients. We investigated the role of the gut microbiota in this adverse drug effect using a mouse model. First, we used germ-free C57BL/6J mice to demonstrate that gut bacteria are necessary and sufficient for weight gain caused by oral delivery of olanzapine. S...

Olanzapine, an atypical antipsychotic, is one of the most commonly used antipsychotics. Though olanzapine is commonly associated with endocrine side effects, it is generally well tolerated by most patients and is rarely associated with urinary incontinence. This report highlights the case of a 23 -year old male patient with schizophrenia who developed severe urinary incontinence following the u...

BACKGROUND Patients with schizophrenia or bipolar disorder (BPD) may be differentially sensitive to antipsychotics. This study assessed the median time to onset, duration, and rate of somnolence associated with asenapine and other antipsychotics in both indications. METHODS Ten clinical trials (n = 4786) were analyzed as five cohorts pooled according to indication and study design. RESULTS ...

A rapid, selective and stability-indicating high performance thin layer chromatographic method was developed and validated for the simultaneous estimation of olanzapine and fluoxetine in combined tablet dosage form. Olanzapine and fluoxetine were chromatographed on silica gel 60 F(254) TLC plate using methanol:toluene (4:2 v/v) as the mobile phase and spectrodensitometric scanning-integration w...

OBJECTIVE The purpose of this study was to compare the efficacy of olanzapine with that of chlorpromazine plus benztropine in patients with treatment-resistant schizophrenia. METHOD One hundred three previously treatment-resistant patients with schizophrenia diagnosed according to the DSM-III-R criteria were given a prospective 6-week trial of 10-40 mg/day of haloperidol. Eighty-four of them ...

OBJECTIVE Despite the frequency of borderline personality disorder (BPD) in patients with acute agitation in emergency departments (EDs), there are few data about the use of intramuscular (IM) psychotropics in those patients. This is the first open-label study with olanzapine in this setting. METHOD Measures were collected prospectively for patients with acute agitation in ED. Consent was obt...
