In this study the effects of the atypical antipsychotics quetiapine and olanzapine, and the typical antipsychotic haloperidol on EEG patterns were retrospectively investigated in 81 patients under stable monotherapy with either drug (quetiapine: n=22, olanzapine: n=37, haloperidol: n=22). These three subgroups were compared with a control group of healthy subjects (n=30) which were matched rega...

OBJECTIVE To examine the prescribing practices of quetiapine for insomnia at a tertiary care child and adolescent psychiatric inpatient unit. METHOD A retrospective chart review was conducted on all admissions in 2013 involving night-time only prescription of quetiapine. We examined patient demographics, discharge diagnoses, physician's written indications for prescriptions, and maximum doses...

BACKGROUND Precise estimated risks and benefits of quetiapine for acute bipolar depression are needed for clinical practice. OBJECTIVE To systematically review the efficacy and the tolerability of quetiapine, either as monotherapy or combination therapy, for acute bipolar depression. METHODS We included all randomized, controlled trials (RCTs) comparing quetiapine with other treatments, inc...

OBJECTIVE This randomized, 24-week, flexible-dose study compared changes in glucose metabolism in patients with DSM-IV schizophrenia receiving initial exposure to olanzapine, quetiapine, or risperidone. METHOD The hypothesized primary endpoint was change (baseline to week 24) in area under the curve (AUC) 0- to 2-hour plasma glucose values during an oral glucose tolerance test (OGTT); primary...

To the Editor: Quetiapine is an atypical antipsychotic agent with less propensity than other atypical antipsychotics to induce antipsychotic-associated hyperprolactinemia in standard recommended therapeutic dosages, and when it does induce the condition at all, the rise in serum prolactin level is only transient. Accordingly, quetiapine has been recommended as an alternative in patients who dev...

OBJECTIVE To determine the effect of adjunctive quetiapine therapy on the sleep architecture of patients with bipolar or unipolar depression. METHODS This is a prospective, single-blind, repeated measures polysomnographic study. Sleep architecture was analyzed by overnight polysomnography, and subjective sleep quality was measured using the Pittsburgh Sleep Quality Index. The Hamilton Rating ...

Heavy drinking contributes to involuntary body movements such as akathisia. Quetiapine has been shown to alleviate symptoms of akathisia; however, its efficacy in the alcohol dependent population is not well established. Thus, we aimed to identify efficacy of Quetiapine in treating akathisia in very heavy drinking alcohol dependent patients. 108 male and female heavy alcohol consuming study par...

OBJECTIVE To evaluate the efficacy and safety of administering quetiapine once vs twice daily. METHOD Utilizing a double-blind design, 21 hospitalized adult men or women with DSM-IV schizophrenia or schizoaffective disorder, who had received unchanged doses (for 2 weeks) of either 400 or 600 mg daily of quetiapine administered in 2 doses, were randomly assigned to once- or twice-daily adminis...

Quetiapine is a new type of antipsychotic drug, with effective protection of pheochromocytoma PC12 cells from oxidative stress-induced apoptosis. Ultraviolet-B radiation can increase reactive oxygen species (ROS) production, resulting in significant inflammatory responses in damaged skin. Thus, the purpose of this study is to explore whether quetiapine protects the skin from intermediate-wave u...
