olanzapine and Sleep-Initiation-and-Maintenance-Disorders

This post hoc analysis of an open-label, single-arm, multicenter study was designed to assess the efficacy, safety, and tolerability of paliperidone extended release (ER) in Chinese patients with non-acute schizophrenia, after switching from olanzapine.. Patients with schizophrenia who were dissatisfied with prior olanzapine treatment switched to flexible paliperidone ER (3-12 mg/day) based on clinical judgment. Change from baseline to week 12 in Positive and Negative Syndrome Scale (PANSS) total scores (primary endpoint), PANSS subscale scores, response rate, Clinical Global Impression-Severity (CGI-S) score, personal and social performance (PSP) scores, patient satisfaction with treatment score, change in sleep quality, level of daytime sleepiness and safety were evaluated.. Out of 118 enrolled patients, 95 (81%) completed the study. Mean duration of study was 76.9 (23.85) days. The primary endpoint, mean (SD) PANSS total score changed significantly from baseline to endpoint (-19.6 [18.71], P <.0001). Secondary endpoints including PANSS subscale score, PSP, patient satisfaction and daytime drowsiness also significantly improved (P <.001). Most commonly reported (≥1%) treatment-emergent adverse events were akathisia (n = 14 [12%]) and insomnia (n = 9 [8%]).. Switching to flexible-dosed paliperidone ER in patients dissatisfied with prior olanzapine treatment achieved good efficacy and tolerability consistently over 12 weeks.

Evaluate the efficacy and safety of asenapine 2.5 mg twice daily (bid; n=97) or 5 mg bid (n=113) versus placebo (n=101) in adults with acute exacerbation of schizophrenia.. Adults with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) schizophrenia diagnosis were randomized to asenapine 2.5 mg bid, 5 mg bid, placebo, or olanzapine 15 mg once daily. The primary objective was to test superiority of asenapine versus placebo as measured by the change from baseline to day 42 in the Positive and Negative Syndrome Scale (PANSS) total score. The key safety objective was to evaluate weight change in asenapine versus olanzapine at day 42.. The primary efficacy endpoint was met; the difference in least squares mean change from baseline to day 42 in PANSS total score between asenapine 5 mg bid and placebo was -5.5 points (unadjusted 95% CI: -10.1, -1.0; multiplicity adjusted P=0.0356). Neither asenapine 2.5 mg bid nor olanzapine 15mg were superior to placebo. Both asenapine groups demonstrated significantly less weight gain than olanzapine at day 42. Significantly higher incidences of oral hypoesthesia and dysgeusia (combined) for asenapine 2.5 mg bid (5.2% vs 0.0%; P=0.0217) and 5 mg bid (7.1% vs 0.0%; P=0.0033) were observed versus placebo. There were no significant differences between asenapine and placebo for insomnia, extrapyramidal symptoms, akathisia, dizziness, or combination of somnolence/sedation/hypersomnia.. This study supports previous efficacy and safety findings of asenapine; asenapine 5 mg bid is the lowest effective dose in adults with schizophrenia. Asenapine was associated with significantly less weight gain than olanzapine at day 42.

Olanzapine's efficacy in schizophrenia is attributed to antagonism of dopamine and serotonin receptors. Olanzapine is also a potent histamine-H1 antagonist that results in weight gain and somnolence. Betahistine is a centrally acting histamine-H1 agonist, and therefore may reduce olanzapine's effect on histamine receptors in the brain. Olanzapine's high affinity for the histamine-H1 receptor warrants the use of high doses of betahistine. Forty-eight healthy women were recruited and randomized to receive either betahistine 144 mg/day or matching placebo for 4 weeks. Due to the high dose of betahistine, olanzapine was started only on the second week and titrated up to 10 mg/day, and co-administration continued for an additional 2 weeks. Only nominal differences in adverse events were noted between the treatment groups. Betahistine caused a 37% reduction in mean weight gain (1.24 kg in the betahistine arm vs. 1.93 kg in the placebo arm; p=.049) and 60% reduction in the mean increase in daytime Epworth sleepiness scores (1.82 units in the betahistine group vs. 3.57 units in the placebo group; p=.042). The present study suggests that betahistine-olanzapine co-administration, in healthy female subjects, yields an acceptable safety profile with mitigation of weight gain and somnolence. This should be further tested in a patient cohort.

To compare the efficacy of 2 atypical anti-psychotic drugs, olanzapine and risperidone, in the treatment of paradoxical insomnia.. In this cross-sectional study over a 2-year period (September 2008 to September 2010), 29 patients with paradoxical insomnia, diagnosed in Kermanshah, Iran by both psychiatric interview and actigraphy, were randomly assigned to 2 groups. For 8 weeks, the first group (n=14) was treated with 10 mg olanzapine daily, and the second group (n=15) was treated with 4 mg risperidone daily. All participants completed the Pittsburgh Sleep Quality Inventory (PSQI) at baseline and at the end of the study.. As expected, a baseline actigraphy analysis showed that total sleep time was not significantly different between the 2 treatment groups (p<0.3). In both groups, sleep quality was improved (p<0.001) with treatment. When comparing the 2 treatments directions, a significant difference emerged (9.21+/-2.35, 6.07+/-4.46) among the 2 treatment groups based on data from the PSQI. Patients who were treated with olanzapine showed greater improvement than patients who were treated by risperidone (p<0.04).. Atypical anti-psychotic drugs such as olanzapine and risperidone may be beneficial options for treatment of paradoxical insomnia. Larger clinical trials with longer periods of follow-up are needed for further investigation.

JNJ-37822681 is a novel, highly selective dopamine D₂ receptor antagonist characterized by a rapid dissociation rate from the dopamine D₂ receptor. This profile was hypothesized to confer antipsychotic efficacy and improved tolerability. In this 12-week study, the efficacy and safety of JNJ-37822681 were evaluated in patients with an acute exacerbation of schizophrenia, randomly assigned (1:1:1:1:1) to JNJ-37822681 (10-, 20- or 30-mg bid), olanzapine (15 mg once-daily), or placebo (for 6 weeks followed by olanzapine for 6 weeks). Of 498 randomized patients, 298 (60%) completed the study. All JNJ-37822681 dose groups and the olanzapine group showed significantly greater reduction in PANSS total score from baseline to week 6 versus placebo (all p-values < 0.001). Least-squares adjusted mean changes from baseline to week 6 in PANSS total score were: -6.4 (placebo); -18.4 (10 mg JNJ-37822681), -17.7 (20 mg JNJ-37822681), -20.0 (30 mg JNJ-37822681) and -22.9 (olanzapine). All JNJ-37822681 groups showed significant improvement versus placebo from baseline to week 6 in the PANSS subscales, Marder factors, Clinical Global Impression of Severity, and in the Subjective Well-Being on Neuroleptics scale (all p-values < 0.05). The most common treatment-emergent adverse events with JNJ-37822681 were insomnia (17%) and akathisia (13%). Incidences of extrapyramidal symptoms were dose-related and were comparable for JNJ-37822681 10 mg bid and olanzapine groups. All JNJ-37822681 dose groups showed lesser weight gain compared with olanzapine. The efficacy and tolerability profile of the JNJ-37822681 10 mg bid was consistent with the study hypothesis.

Atypical antipsychotics are increasingly drugs of first choice in schizophrenia. Amisulpride, a new atypical antipsychotic, is reported to be effective for both positive and negative symptoms of schizophrenia in Western countries but Indian experience is limited. The aim of the present study was therefore to conduct a trial of amisulpride versus olanzapine in Indian schizophrenia patients.. Eighty adult patients of either sex were randomized to receive standard doses of the two drugs orally, in a single blind manner, for 12 weeks, with follow up at 4 and 8 weeks. Effectiveness was assessed by changes in scores on the Brief Psychiatric Rating Scale (BPRS), Scale for Assessment of Positive Symptoms (SAPS), Scale for Assessment of Negative Symptoms (SANS), and physician-administered Clinical Global Impression (CGI) scale. Tolerability was assessed by treatment-emergent adverse drug reactions (ADRs).. Evaluable were 39 patients on amisulpride and 38 on olanzapine. The groups were comparable at baseline with respect to demographics, illness duration and rating scores. Final BPRS score was lower for olanzapine (33.2 +/- 9.44) than for amisulpride (37.7 +/- 9.67). SAPS and SANS scores and CGI rating improved individually in both arms but remained comparable between groups throughout the study period, but olanzapine reduced SAPS score to a greater extent. ADRs were encountered in 67.5% and 47.5% of patients (p = 0.113) on amisulpride and olanzapine, respectively. Tremor and insomnia were more frequent with amisulpride, while olanzapine caused more weight gain and sedation. No serious ADRs occurred.. Amisulpride, although comparable to olanzapine on some measures, did not match the improvement seen with the latter drug in BPRS and SAPS scores. Despite differences in ADR profiles, overall tolerability was satisfactory for both drugs. In Indian patients, amisulpride should therefore be an alternative to olanzapine to a limited extent, such as when weight gain and sedation are undesirable.

The authors investigated the influence of aging on the improvement of subjective sleep quality by atypical antipsychotic drugs in patients with schizophrenia.. Subjects were 86 inpatients (mean age: 61.4 years) who had been receiving treatment with conventional antipsychotic drugs and who met DSM-IV criteria for schizophrenia. Their antipsychotic medication was changed from conventional antipsychotics to one of four atypical antipsychotic drugs (olanzapine, perospirone, quetiapine, or risperidone). Patients were grouped by age (older or younger than 65 years). Subjective sleep quality and psychopathology were assessed twice: 1) at baseline, and 2) 8 weeks after switching to the atypical antipsychotic drugs. Subjective sleep quality was assessed with the Pittsburgh Sleep Quality Index (PSQI), and the Positive and Negative Syndrome Scale (PANSS) was used to measure psychopathology.. The proportion of the patients who experienced improved subjective sleep quality was significantly higher in the elderly than in the middle-aged group. Logistic-regression analysis revealed that the improvement in subjective sleep quality through administration of atypical antipsychotic drugs was predicted by increased age, daytime dysfunction, and longer sleep latency at baseline.. These results demonstrate that atypical antipsychotic drugs are beneficial to the quality of sleep in elderly patients with schizophrenia.

It has been suggested that the atypical antipsychotic drugs may induce a rapid improvement in individuals with melancholic depression. This might reflect a specific or non-specific effect on mood and other parameters. To examine this issue, ten consecutive patients, for whom olanzapine augmentation was judged a clinically appropriate strategy, were asked to complete daily ratings of depression severity and component features for 1 week. Of the six rapid responders, there was a 52% group improvement in the first day and 89% improvement at 1 week. Item analyses suggested the most rapid impact was evident for insomnia, compared to a slower and linear improvement in depressed mood. Such findings may assist in an understanding of the mechanisms underlying augmentation with atypical neuroleptic drugs.

Cancer patients often experience symptoms such as anorexia, anxiety and insomnia, which can impact their quality of life. Randomized placebo-controlled trials support prophylactic use of olanzapine for the prevention of nausea and vomiting due to moderate and high-emetic risk chemotherapy. In the setting of palliative care, olanzapine is increasingly utilized as an off-label treatment of symptoms including anorexia-cachexia, anxiety, and insomnia. The following case reports will highlight the potential benefits and risks of off-label olanzapine use for symptom management in cancer patients.. Patient 1 is a female in her 70s with stage IV infiltrating ductal carcinoma of the right breast was having trouble tolerating treatment with letrozole, palbociclib, and denosumab due to uncontrolled nausea resulting in weight loss. Her nausea was refractory to multiple anti-emetics. Low dose olanzapine (2.5 mg) prevented nausea and allowed her to tolerate treatment. Patient 2 is a male in his 50s with renal cell carcinoma, who was receiving treatment with cabozantinib, presented with uncontrolled pain improved with opioid rotation from oxycodone to morphine. He was also experiencing uncontrolled anxiety despite treatment with alprazolam. Alprazolam was weaned and replaced with olanzapine resulting in improvement of his symptoms. Patient 3 is a male in his 60s with pancreatic adenocarcinoma who presented with muscle weakness and fatigue resulting in discontinuation of gemcitabine plus cisplatin. He also had symptoms of depression, poor appetite, and sleep problems. He was prescribed short course of dexamethasone 4 mg by mouth twice daily and olanzapine 5 mg by mouth nightly to improve symptoms. One week after, he presented with confusion and workup revealed hyperammonia which was treated with lactulose, which led to the return of baseline mentation.. Olanzapine antagonizes multiple receptors and has potential to treat a host of symptoms including nausea, anorexia, anxiety, and insomnia, but healthcare providers should be mindful of potential risks and unclear benefits for off-label indications. More research and funding are needed evaluating off-label use of olanzapine for palliation of symptoms in cancer patients who are often frail and susceptible to adverse events.

Antipsychotics with dopamine (D2) receptor antagonism can be effective for emesis in cancer patients. Extrapyramidal symptoms (EPS) induced by typical antipsychotics can be exacerbated by other D2 receptor antagonists. We describe a case of persistent EPS induced by long-term, intermittent administration of low-dose olanzapine along with metoclopramide for emesis.. A 59-year-old pancreatic cancer patient underwent chemotherapy for 7 months. He was referred to the psychiatry department because of restlessness and insomnia. Although he did not have obvious depressive symptoms, he was anxious about the cancer treatment. For chemotherapy-induced nausea, he had been prescribed 5 mg of olanzapine intermittently for 7 months. He had last used the drug 9 days before presenting it to us. Additionally, he received metoclopramide and palonosetron as antiemetics. We considered akathisia and cancer-related anxiety/agitation as possible causes of restlessness and insomnia, and prescribed clonazepam. However, his symptoms worsened, resulting in hospitalization. We reconsidered his symptoms as cancer-related anxiety/agitation and prescribed quetiapine. Although it was effective, he had tremors and was assessed by a neurologist. Considering the clinical manifestations of rigidity, postural reflex disorder, and a mask-like face, we suspected drug-induced parkinsonism and replaced quetiapine with biperiden on the next day, leading to his discharge after 2 weeks. He did not have symptom recurrence even after discontinuation of biperiden.. Long-term, intermittent administration of low-dose antipsychotics with other antiemetics having D2 receptor antagonism can cause prolonged EPS. Especially in cancer patients, who often require polypharmacy, clinicians should consider exacerbated adverse effects due to drug interactions.

Olanzapine is increasingly used as a sleep aid in hospitalized patients. Although thought to have less extrapyramidal effects, known side effects include oversedation, arrythmias, and hypotension. We present the unusual case of hyperventilation with respiratory alkalosis after the administration of olanzapine for insomnia in an elderly postoperative patient. This led to a second admission to the intensive care unit with invasive interventions including mechanical ventilation and vasopressor support. Caution must be exercised in prescribing antipsychotics for off-label use, especially in a population whose baseline characteristics can affect the pharmacokinetics of second-generation antipsychotics.

This study aimed to compare the antiemetic efficacy and safety of a four-drug combination with those of a standard three-drug combination in Japanese patients with breast cancer treated with anthracycline. We retrospectively analyzed data from Japanese patients with breast cancer, who had received their first cycle of anthracycline and were treated with aprepitant, palonosetron, and dexamethasone with or without olanzapine. This retrospective observational study was performed at Ehime University Hospital using the electronic medical records. Multivariable and propensity score-adjusted analyses were performed to compare the onset of complete response (CR) failure between the groups. One-hundred and thirty patients were included in this study and the four- and three-drug group had 22 and 108 patients, respectively. Similar to multivariable logistic regression analysis, propensity-adjusted logistic regression analysis revealed that the four-drug group was markedly associated with a decreased odds of CR failure in the overall, acute, and delayed phases (odds ratio [OR]: 0.27, 95% confidence interval [CI]: 0.10-0.73; OR: 0.28, 95% CI: 0.10-0.76; and OR: 0.15, 95% CI: 0.04-0.57, respectively). Additionally, treatment-related adverse events were well tolerated in both the groups. These findings suggest that the antiemetic efficacy of the four-drug combination is superior to that of the standard three-drug combination.

This study aims to explore and analyze the condition of concurrent diseases and medicine use of traditional Chinese medicine (TCM) and western medicine among the patients with insomnia. One thousand and sxity seven cases of data from 20 national hospitals' hospital information system (HIS) databases were collected. The frequent concurrent diseases included hypertension (26.9%), brain blood supply insufficiency (24.93%), cerebral infarction (19.49%), blood lipoprotein disturbance (15.28%), coronary heart disease (14.15%), headache (10.68%), chronic gastritis (8.81%), type 2 diabetes mellitus (7.87%), depressive disorder (7.4%) and anxiety disorder (6.65%). The 10 most frequently-used western drugs included alprazolam (35.99%), aspirin (25.4%), olanzapine (24.18%), cinepazide (23.06%), flupentixol & melitracen (18.74%), zolpidem (18.37%), oxiracetam (15.65%), estazolam (15%), aniracetam (13.4%) and piracetam (13.31%). The 10 most frequently-used TCM included Shuxuening injection (16.4%), Shuxuetong injection (15.18%), extract of ginkgo biloba leaf (14.71%), gastrodin (12.46%), Dengzanxixin injection (11.34%), Xueshuantong (8.53%), Danhong injection (6.37%), compound liquorice tablet (5.81%), Sanqi Tongshu capsule (5.72%) and sowthistle-leaf ixeridium injection (5.34%). Among all combined uses, the most frequent western drug use was alprazolam and olanzapine, while combined use of hypnotic drug and Huoxuehuayu formula is the most frequent. This study concludes that the concurrent diseases mainly include cardio-cerebrovascular diseases, metabolic disorders and anxiety-depression disorders, with increasing tendency of diseases types by ages, especially for cardio-cerebrovascular diseases. The most frequently-used hypnotic is alprazolam in the insomnia patients, and it is worth being concerned about the off-label use of olanzapine as an antipsychotic for the treatment of insomnia However, due to the fact that all cases data are from the inpatients, these findings have some limitations.

In patients with bipolar disorder, olanzapine is commonly used to prevent episodes of acute mania. The drug pramipexole can, in theory, undermine the protective effect of olanzapine. Olanzapine is a dopamine D2 receptor antagonist and pramipexole is a mixed dopamine D2 /D3 receptor agonist. These drugs may therefore theoretically counteract their pharmacological effects. To date, there are no known cases in the literature where this interaction has been described.. We report on a case where a patient with bipolar disorder developed mania after taking pramipexole in combination with olanzapine, and describe the pharmacological background of this interaction.. A patient with bipolar I disorder was hospitalized with a manic episode characterized by agitation and insomnia after taking pramipexole for restless leg syndrome (RLS) in combination with olanzapine. Co-medication, i.e., lithium and mirtazapine, and other circumstances are not likely to have contributed to this effect.. There is a probable interaction between pramipexole and olanzapine, where pramipexole undermines the protective effect of olanzapine, provoking an episode of acute mania and hospitalization. This interaction is of clinical importance since pramipexole is the treatment of choice for RLS, a condition often seen in end-stage renal disease, and has also been investigated as an antidepressant therapy in patients with bipolar disorder.

Offering a new perspective on sleep state misperception, we discuss a patient who presented with sleep state misperception and was ultimately diagnosed with delusional disorder. A 60-year-old woman with chief complaints of insomnia, agitation, and suicidal ideation, was admitted to an inpatient psychiatric ward. Based on information from her family and a mental state examination, her primary diagnosis was sleep state misperception. She was treated with Trazodone. Because she was unresponsive to the treatment, a full psychiatric evaluation and wrist actigraphy report were undertaken, resulting in a revised diagnosis of delusional disorder. She was started on Olanzapine and, after 6 weeks was discharged with good improvement. Sleep state misperception might be considered not just as a sleep disorder, but also as a psychiatric disorder with psychotic symptoms. Further research is recommended.

Nightmares and insomnia in combat-related post-traumatic stress disorder (PTSD) might be resistant to treatment with selective serotonin reuptake inhibitors (SSRIs) and benzodiazepines.. We describe five case reports of patients suffering from long-lasting and intractable nightmares and insomnia. They were given different psychotropic agents in past few years, with no improvement in their sleep disturbance. Olanzapine was added to the current treatment regimen.. Both nightmares and insomnia improved rapidly after olanzapine institution in all of five patients. No adverse events of olanzapine were reported.. Olanzapine augmentation might be useful in alleviating treatment-resistant nightmares and insomnia in patients with combat-related PTSD.

Four patients affected by severe Parkinson's disease developed leucopenia (900-1200 WBC) during treatment of psychosis (3) or untreatable insomnia (1) with clozapine (37.5-75 mg/day). Clozapine withdrawal was followed by recovery of leucopenia (4000-6000 WBC) in two weeks with no need for the administration of leucokines. After 1-6 months olanzapine was administered (increasing the dose from 2.5 to 10 mg/day) to treat persisting disturbances, but the drug induced severe worsening of parkinsonism and also this drug had to be withdrawn.
