Olanzapine is prescribed for a number of psychiatric disorders, including schizophrenia, bipolar mania, and unipolar and bipolar depression. Olanzapine treatment is associated with tolerability issues such as metabolic adverse effects (e.g. weight gain, increase in blood glucose, triglycerides and total cholesterol levels), extrapyramidal symptoms [EPS] (e.g. parkinsonism, akathisia, tardive dyskinesia) and sedative adverse effects. Metabolic issues lead to some long-term consequences, which include cardiovascular diseases (CVD) and type 2 diabetes mellitus, and these complications cause high rates of mortality and morbidity among patients with severe mental illnesses. The expanded indications of olanzapine in psychiatry suggest a need to investigate whether there is a difference in the incidence and severity of adverse effects related to category diagnosis. Are the adverse effects expressed differently according to phenotype? Unfortunately, there are no reported studies that investigated these differences in adverse effects associated with olanzapine treatment in psychiatric patients with different phenotypes.. The aim of the present meta-analysis is to separately examine olanzapine-induced cardiometabolic adverse effects and EPS in patients with schizophrenia and affective disorders.. A search of computerized literature databases PsycINFO (1967-2010), PubMed (MEDLINE), EMBASE (1980-2010) and the clinicaltrials.gov website for randomized clinical trials was conducted. A manual search of reference lists of published review articles was carried out to gather further data.. Randomized controlled trials were included in our study if (i) they assessed olanzapine adverse effects (metabolic or extrapyramidal) in adult patients with schizophrenia or affective disorders; and (ii) they administered oral olanzapine as monotherapy during study.. Two reviewers independently screened abstracts for choosing articles and one reviewer extracted relevant data on the basis of predetermined exclusion and inclusion criteria. It should be mentioned that for the affective disorders group we could only find articles related to bipolar disorder.. Thirty-three studies (4831 patients) that address olanzapine monotherapy treatment of adults with schizophrenia or bipolar disorder were included in the analysis. The primary outcomes were metabolic adverse effects (changes in weight, blood glucose, low-density lipoprotein, total cholesterol and triglyceride levels). The secondary outcomes of our study were assessing the incidence of some EPS (parkinsonism, akathisia and use of antiparkinson medication). The tolerability outcomes were calculated separately for the schizophrenia and bipolar disorder groups and were combined in a meta-analysis. Tolerability outcomes show that olanzapine contributes to weight gain and elevates blood triglycerides, glucose and total cholesterol levels in both schizophrenia and bipolar disorder patients. However, olanzapine treatment produced significantly more weight gain in schizophrenia patients than in bipolar disorder patients. In addition, increases in blood glucose, total cholesterol and triglyceride levels were higher in the schizophrenia group compared with the bipolar disorder group, even though these differences were not statistically significant. Based on our results, the incidence of parkinsonism was significantly higher in the schizophrenia group than in the bipolar disorder group. Subgroup analysis and logistic regression were used to assess the influence of treatment duration, dose, industry sponsorship, age and sex ratio on tolerability outcome.. Our results suggest that schizophrenia patients may be more vulnerable to olanzapine-induced weight gain. The findings may be explained by considering the fact that in addition to genetic disposition for metabolic syndrome in schizophrenia patients, they have an especially high incidence of lifestyle risk factors for CVD, such as poor diet, lack of exercise, stress and smoking. It might be that an antipsychotic induces severity of adverse effect according to the phenotype.

All treatment guidelines for acute mania recommend monotherapy with either mood stabilizers (MS) or antipsychotics. The objective of this analysis was to compare the efficacy and acceptability of both drug classes in an expanded set of clinical trials in acute mania.. Randomized double-blind trials comparing MS vs second generation antipsychotics (SGA) in acute mania were identified in a systematic literature search. Change in mania rating scale, responder rates and dropout rates were compared by treatment assignment using Review Manager version 5.0.. Nine studies totaling 1631 patients that compared the MS lithium or valproate against a number of SGAs, and which reported one or more analysis endpoints were identified. Statistically significant advantages were noted in favour of SGA over MS for standardized mean difference (SMD) for change in mania scores (-0.22 [95% CI -0.33 to -0.11]; p < 0.0001), responder rate risk difference (7% [95% CI 1% to 13%]; p = 0.02), and dropout risk difference (-5% [95% CI -10% to -1%]; p = 0.02). This change in SMD for mania scores is equivalent to a 2.5-3 point difference in Young Mania Rating Scale score. Similar trends for SMD were noted when comparing subgroups of lithium and valproate studies against SGAs.. Over half the included studies included olanzapine, and the applicability of these findings, especially to first generation antipsychotic drugs, requires confirmation. This analysis could not assess the relative efficacy of combined MS/SGA vs individual monotherapies.. In acute mania, monotherapy with SGAs demonstrates statistically significant advantages over MS in terms of both efficacy and acceptability, and may be preferable for initial choice of treatment.

Patients with bipolar disorder tend to experience most of their illness in the depressed phase. Existing antidepressant therapies are effective in bipolar depression but carry a risk of treatment-emergent mania or increased phase cycling. Other therapies such as lithium may not be particularly effective, or may not currently be licensed for the acute phase, such as lamotrigine. A combination of the antipsychotic olanzapine and the serotonin reuptake inhibitor fluoxetine has been investigated in both bipolar depression and other affective disorders such as psychotic depression and treatment-refractory depression. The combination's possible mode of action, pharmacokinetics, drug interactions, clinical efficacy and safety and tolerability have been reviewed.

Since the previous publication of Canadian Network for Mood and Anxiety Treatments (CANMAT) guidelines in 1997, there has been a substantial increase in evidence-based treatment options for bipolar disorder. The present guidelines review the new evidence and use criteria to rate strength of evidence and incorporate effectiveness, safety, and tolerability data to determine global clinical recommendations for treatment of various phases of bipolar disorder. The guidelines suggest that although pharmacotherapy forms the cornerstone of management, utilization of adjunctive psychosocial treatments and incorporation of chronic disease management model involving a healthcare team are required in providing optimal management for patients with bipolar disorder. Lithium, valproate and several atypical antipsychotics are first-line treatments for acute mania. Bipolar depression and mixed states are frequently associated with suicidal acts; therefore assessment for suicide should always be an integral part of managing any bipolar patient. Lithium, lamotrigine or various combinations of antidepressant and mood-stabilizing agents are first-line treatments for bipolar depression. First-line options in the maintenance treatment of bipolar disorder are lithium, lamotrigine, valproate and olanzapine. Historical and symptom profiles help with treatment selection. With the growing recognition of bipolar II disorders, it is anticipated that a larger body of evidence will become available to guide treatment of this common and disabling condition. These guidelines also discuss issues related to bipolar disorder in women and those with comorbidity and include a section on safety and monitoring.

The purpose of this review is to critically review the current literature on olanzapine with an emphasis on emergent themes and key findings in the use of this agent for the treatment of mood disorders and schizophrenia. New information continues to emerge on the impact of olanzapine on schizophrenia and on aspects of the course of mood disorders. There are also continued efforts to understand, predict and manage the side-effect risk with olanzapine.

Depression can occur either with or without alternation with periods of mania. Depression that alternates with mania (bipolar depression) is a particularly difficult problem in clinical practice. The evidence base of the treatment for this condition is not strong and the choices at best are limited. Furthermore, although there are a number of effective antidepressants for the non-cycling variety ('unipolar' major depression), > 50% of patients experience incomplete response to any given drug. Given the proportion of the population involved, these represent fairly sizeable markets. Studies over the last several years indicate that the combination of the novel antipsychotic olanzapine and the serotonin-selective re-uptake inhibitor (SSRI), fluoxetine, may be effective for both conditions. One trial in 28 patients showed that this combination was an effective treatment, compared to the individual components with unipolar depressed patients who had not responded to two antidepressants of different chemical classes. Two subsequent large-scale attempts at replication have resulted in failed trials. Patients randomly assigned to antidepressant monotherapies showed a good response, indicating that the populations being studied were not actually treatment-resistant; therefore, more research is needed. Alternatively, a recent study showed that monotherapy with olanzapine produced a greater effect than placebo in bipolar depression and the combination of olanzapine and fluoxetine yielded an even more robust response. However, important questions remain, e.g., the issue of comparative effectiveness, that is to say, whether the same result could occur with combinations of other novel antipsychotics and SSRIs. In addition, there remain significant concerns regarding the safety and tolerability of olanzapine in these populations. Essential questions about the potential for substantial weight gain, Type II diabetes and for the development of tardive dyskinesia (a syndrome of permanent, disfiguring abnormal involuntary movements) remain. These problems will have to be vigorously addressed in order to achieve a substantial market penetration for these conditions.

Pregnancy presents a special problem to the clinician treating bipolar disorders in women. Since the first episode of mania typically occurs before the age of 30, many women in their prime childbearing years may be exposed to potentially teratogenic mood-stabilizing agents. This exposure may also continue for the nursing infant during lactation. Pregnancy itself can exacerbate bipolar symptoms and also alter the pharmacokinetics of mood-stabilizing drugs. Risks to mother and fetus can be reduced with a number of simple strategies, including monotherapy with the lowest effective dose of a drug for the shortest period necessary, periconceptional use of multivitamins with folate, prescription of drugs with established safety records, and avoidance of exposure to antimanic agents during the first trimester of pregnancy. In this article, we review existing evidence on the risks to fetuses and nursing infants of mothers taking specific mood-stabilizing agents, and we present appropriate management guidelines designed to minimize these risks.

The atypical antipsychotics have a low incidence of extrapyramidal side effects (EPS), have improved tardive dyskinesia profiles, and have a broad range of therapeutic efficacy. These agents offer important therapeutic advantages that extend beyond their initial regulatory approval in several conditions and patient groups. The use of atypical antipsychotics is most relevant in the treatment of mood disorders, where these medications are being used increasingly for acute mood stabilization and in patients who are resistant to other treatments. Similar circumstances and clinical advantages pertain to the use of atypical antipsychotics in the treatment of behavioral disturbances in patients with dementia and in the management of personality disorders-both circumstances where conventional antipsychotics were initially poorly tolerated because of EPS. The low incidence of EPS associated with atypical antipsychotics is highly beneficial in several neuropsychiatric conditions. The extent to which endocrine and metabolic dysregulations associated with atypical antipsychotics will influence antipsychotics' role remains to be determined. As therapeutic opportunities evolve and diversify, atypical antipsychotics, because of favorable adverse-effect profiles, will have enhanced patient tolerability and use in nonpsychiatric conditions.

Depression in schizophrenia may be partially responsible for the increased suicide rate in schizophrenic patients, which is more than 20 times higher than that found in the general population. Affective disorders in patients with schizophrenia are associated with a poor outcome, an increased risk of relapse, and a high rate of suicide. There is evidence that atypical antipsychotics may contribute to a reduction in suicidality, and although the new drugs are marketed for the treatment of schizophrenia, their novel psychopharmacologic effects suggest the possibility of other therapeutic applications. Recent studies of the efficacy of the novel antipsychotics found that these agents may produce an antidepressant effect in schizophrenia and may be used as either an adjunctive medication or an alternative to mood stabilizers in patients with affective disorders.

Atypical antipsychotics have become the treatment of choice for patients experiencing a first episode of schizophrenia. In addition, they are often prescribed for conditions such as bipolar disorder and dementia. While clinical trials have not yet established the efficacy of the atypical antipsychotics for these uses, a number of reports offer preliminary evidence that the atypical antipsychotics may be beneficial for affective disorders, substance abuse disorder, senile dementia, and pathologic aggression. Atypical agents may be particularly effective and tolerable in elderly patients who are especially susceptible to the adverse effects of conventional antipsychotic medication. Lower dosages are more necessary for the elderly than for younger adults. Current evidence suggests that clozapine is the most effective atypical antipsychotic for neuroleptic-resistant patients. Risperidone, olanzapine, and quetiapine may also be effective in a subset of these patients.

Chemotherapy-induced delayed emesis (DE) can affect up to 50% to 70% of patients receiving moderately and highly emetogenic chemotherapy, although rates are improving. DE most commonly occurs within the first 24 to 48 hours of chemotherapy administration and can persist for 2 to 5 days. Olanzapine, due to its activity at multiple dopaminergic, serotonergic, muscarinic, and histaminic receptor sites, has potential as antiemetic therapy. A phase I study was designed with olanzapine, using a four-cohort dose escalation of 3 to 6 patients per cohort, for the prevention of DE in cancer patients receiving their first cycle of chemotherapy consisting of cyclophosphamide, doxorubicin, platinum, and/or irinotecan. All patients received standard premedication. Olanzapine was administered on days -2 and -1 prior to chemotherapy and continued for 8 days (days 0-7). Episodes of vomiting as well as daily measurements of nausea, sedation, and toxicity were monitored at each dose level. Fifteen patients completed the protocol. No grade 4 toxicities were seen, and three patients experienced a dose-limiting toxicity (grade 3) of a depressed level of consciousness during the study. The maximum tolerated dose appeared to be 5 mg (for days -2 and -1) and 10 mg (for days 0-7). Four of six patients receiving highly emetogenic chemotherapy (cisplatin, > or = 70 mg/m2) and nine of nine patients receiving moderately emetogenic chemotherapy (doxorubicin, > or = 50 mg/m2) had complete control (no vomiting episodes) of DE. Therefore, olanzapine may be an effective agent for the prevention of chemotherapy-induced DE. A phase II trial is underway.

The first double-blind placebo-controlled clinical trial of an atypical neuroleptic medication is being conducted in symptomatic treatment-seeking patients meeting new diagnostic criteria for a putative prodromal syndrome. This identifies them as being at high risk for developing psychosis in the near future. The study aims include prevention of psychosis onset and disability, as well as palliation of ongoing symptomatology. The purpose of this report is to describe the study's "prodromally symptomatic" sample at baseline, i.e., at intake immediately prior to randomization and prior to receiving study medication. Sixty treatment-seeking patients meeting prodromal inclusion criteria were recruited across four sites: New Haven, CT (n=39), Toronto, Ontario (n=9), Calgary, Alberta (n=6), and Chapel Hill, NC (n=6). The sample was young (median age 16), largely male (65%), and came from families with high titers of serious mental illness (44%). Most patients (93%) met criteria for the Attenuated Positive Symptom (APS) prodromal syndrome and presented with significant but nonpsychotic suspiciousness, perceptual aberrations, unusual thought content, and conceptual disorganization. They presented with minimal to mild affective symptoms and substance use/abuse, but they were quite functionally compromised (mean Global Assessment of Functioning (GAF) score=42). The prodromal sample was compared with other clinical-trial samples of adolescent depression, adolescent mania, and first episode schizophrenia. Prodromal patients proved not to be depressed or manic. They were less severely ill than untreated first episode schizophrenia but more severely ill than treated first episode schizophrenia. While not psychotically disabled, these patients nevertheless present with a clinical syndrome. Subsequent reports will detail the effects of drug versus placebo on prodromal symptoms, neuropsychological profile, and the rate of conversion to psychosis.

Atypical antipsychotics are the first-line treatment for psychosis and are commonly used for behavioural problems in people with intellectual disabilities (ID), but a comprehensive evidence base for this approach is lacking. We studied prescription trends and the clinical effectiveness of risperidone and olanzapine in people with ID in a clinical, naturalistic setting. The results suggest that both drugs are well tolerated and effective in treating target symptoms across a range of diagnoses and ID. Both risperidone and olanzapine appear to reach full efficacy within 3 months, after which improvement reaches a plateau, as reflected in the Clinical Global Impression-Improvement scale. Compliance with both drugs is high. Olanzapine tended to be prescribed mostly for psychotic disorders, and showed good rates of response, whereas risperidone was prescribed mostly for people with behavioural disturbance associated with a psychiatric diagnosis. Furthermore, approximately one-quarter of the risperidone group were prescribed the medication for a behavioural disorder associated with a pervasive developmental disorder. Again, the medication was broadly effective in treatment. Both medications were also used to effectively treat affective disorders in a small percentage of patients. This study appears to indicate that both medications could be of significant clinical benefit for people with ID across a wide range of diagnoses and level of ID, although further controlled trials are required.

Limbic encephalitis is an inflammatory process of the limbic structures, with polymorphic clinical features, caused by paraneoplastic and nonparaneoplastic conditions and infections. We describe a case of neurosyphilis limbic encephalitis, presenting with reversible Geschwind syndrome (hyperreligiosity and hypergraphia) and mood disorder due to the predominant involvement of left mesial temporal structures in a previously healthy 34-year-old, left-handed woman. Because neurosyphilis can mimic common neuropsychiatric syndromes, it should be included in the differential diagnosis of psychiatric disorders with suspected general medical causes. This case of nondominant limbic encephalopathy caused by syphilis infection highlights the relevance of a careful investigation for secondary psychotic, mood, and personality disorders when assessing new-onset psychiatric illness and the importance of a multidisciplinary approach to provide a better outcome in patients with neurosyphilis.

A 94 year old woman with a late-onset paraphrenia was referred to our clinic from a community care center. The patient showed symptoms of paranoia and auditory hallucination. The patient was in conflict with her neighbors regarding noise-related problems and was experiencing loss of appetite. Because the patient had a strong aversion to outpatient treatment due to difficulty in commuting, home visits were commenced. Improvements were observed after administration of 2.5 mg per day of olanzapine.In home medical care, precise definitive diagnosis and determination of treatment approach is necessary under limited time and resources. The fact that elderly people often exhibit psychological symptoms such as hallucinations is well known among clinical professions. However, this is not well known among home care patients, families and other professionals, and, therefore, is often overlooked. As the population ages further, it can be predicted that cases of elderly patients requiring treatment for psychological symptoms will increase in home medical care situations. In Japan, with a super-aging society, understanding and continuously supporting late-onset paraphrenia among elderly people is a pressing issue for all communities in advancing home medical care and nursing.

Rarely screened in psychiatric patients, primary and/or secondary Carnitine deficiency could be influencing and/or mimicking the mood symptoms of our patient population. The brain and specifically neurons are highly vulnerable to impairments in oxidative metabolism, which can lead to neuronal cell death and disorders of neurotransmitters causing changes in cognition and behavior. For this reason, identification of this disorder is important since its treatment could result in symptom improvement and better quality of life of our patients. We present a case where exacerbation of mood symptoms was associated to primary and secondary Carnitine deficiency.

We report the case of a 69 year-old female patient who was hospitalized for Diogenes syndrome, defined by marked self-neglect, social withdrawal and excessive hoarding, leading to squalor. Somatic causes were eliminated. Her personal history showed an eight-year depressive episode followed by a 20-year hypomanic episode without remission, followed by a persistent manic episode associated with Diogenes syndrome for four years. The Diogenes syndrome was successfully treated with mood stabilizers. Mood disorders - in particular chronic mania (i.e. a manic episode lasting more than two years) - should be considered in cases of Diogenes syndrome and in current classifications.

Catatonia is a rare complication of multiple sclerosis (MS). We present a case of a 28-year-old inpatient with MS successfully treated with electroconvulsive therapy (ECT) after developing a catatonic syndrome. A subsequent relapse also responded to ECT, after which the patient received maintenance ECT for 13 months without complications. Follow-up 18 months later did not reveal any evidence of neurological deterioration. We conclude that ECT was a safe and effective treatment in this MS patient.

Bipolar disorder has an associated economic burden due to its treatment, including medication and hospitalization costs as well as costs associated with treatment of comorbid conditions. This study compared healthcare costs in patients treated with a mood stabilizer and adjunctive aripiprazole versus adjunctive olanzapine, quetiapine, risperidone or ziprasidone.. A retrospective propensity score-matched cohort study was conducted in the LabRx integrated claims database from January 2003 to December 2006. Patients (18-65 years) with bipolar disorder and 180 days of pre-index enrolment without atypical treatment and 90 days post-index enrolment were eligible. Mood stabilizer therapy was initiated prior to index atypical prescription. Generalized gamma regressions were used to compare the total healthcare costs of adjunctive aripiprazole treatment and treatment with adjunctive olanzapine, quetiapine, risperidone or ziprasidone.. After controlling for differences in baseline characteristics and pre-index cost, psychiatric costs and subtotal psychiatric and general medical costs were higher for all adjunctive atypicals than adjunctive aripiprazole (p<0.001). Based on gamma regressions cost ratios, there was no significant difference in general medical costs between aripiprazole and ziprasidone, olanzapine, or quetiapine; risperidone general medical costs were 18% higher versus aripiprazole (p=0.041). Aripiprazole pharmacy costs were higher than quetiapine and risperidone (p<0.001) but not olanzapine or ziprasidone. Total healthcare costs were higher for ziprasidone, olanzapine, or risperidone (p<0.001) but not quetiapine.. Methodological restriction of patients to those newly initiated on an atypical antipsychotic and incomplete medication history limit the generalizability of the findings.. Adjunctive aripiprazole may have economic benefits over other atypicals in terms of lower psychiatric treatment costs than adjunctive olanzapine, quetiapine, risperidone or ziprasidone, and lower total healthcare costs than adjunctive olanzapine, risperidone or ziprasidone.

In 2005, the Canadian Network for Mood and Anxiety Treatments (CANMAT) published guidelines for the management of bipolar disorder. This update reviews new evidence since the previous publication and incorporates recommendations based on the most current evidence for treatment of various phases of bipolar disorder. It is designed to be used in conjunction with the 2005 CANMAT Guidelines. The recommendations for the management of acute mania remain mostly unchanged. Lithium, valproate and several atypical antipsychotics continue to be recommended as first-line treatments for acute mania. For the management of bipolar depression, new data support quetiapine monotherapy as a first-line option. Lithium and lamotrigine monotherapy, olanzapine plus selective serotonin reuptake inhibitors (SSRI), and lithium or divalproex plus SSRI/bupropion continue to remain the other first-line options. First-line options in the maintenance treatment of bipolar disorder continue to be lithium, lamotrigine, valproate and olanzapine. There is recent evidence to support the combination of olanzapine and fluoxetine as a second-line maintenance therapy for bipolar depression. New data also support quetiapine monotherapy as a second-line option for the management of acute bipolar II depression. The importance of comorbid psychiatric and medical conditions cannot be understated, and this update provides an expanded look at the prevalence, impact and management of comorbid conditions in patients with bipolar disorder.

Previous studies comparing olanzapine (OLZ) and risperidone (RIS) have tended to focus on multiple-episode patients, with no studies examining their comparative efficacy in a non-selective sample of first-episode psychosis.. The Early Psychosis Prevention and Intervention Centre in Australia had admitted 786 first-episode psychosis (FEP) patients between 1998-2000. Data were collected from the medical records (MR) of 367 patients, which met inclusion criteria. The primary objective was to evaluate the efficacy of OLZ vs. RIS as measured by CGI-S, CGI-BP (symptomatic level), GAF and SOFAS (functioning level).. 367 FEP patients were entered into the study, 278 in the RIS- (2.7 mg/day) and 89 in the OLZ group (10.2 mg/day). No between-group differences were found in non-affective FEP (n = 273). In affective FEP patients (n = 94), mainly treated for acute mania (86.7 %), OLZ treatment was related to better response on the symptomatic (CGI-S; p = .002), but not on the functioning level (GAF and SOFAS; ns). There were trends in the OLZ group towards a higher rate of remission of positive symptoms ( p = .054) and a shorter treatment duration to reach this remission in affective FEP patients ( p = .077). More extrapyramidal side effects ( p <.001) were related to RIS and more weight gain to OLZ-treatment ( p <.001).. Despite the limitations of a retrospective MR design, study results suggest equal therapeutic efficacy of OLZ and RIS in non-affective FEP and some therapeutic advantages of OLZ compared to RIS in affective FEP patients, especially in those with acute mania. Results may serve as hypotheses for future randomised controlled trials.

To compare prescribed daily doses (PDDs) of psychotropic drugs in several European centres.. A one-day census of psychotropic drug prescriptions to 613 patients in 39 acute psychiatric wards in ten countries.. Patients in Spain were on most drugs; patients in Germany were on the fewest. Chlorpromazine equivalents in Denmark, England, Germany and Spain were at high levels as were diazepam equivalents in Belgium, Finland, The Netherlands and Norway. Newer anti-psychotics were used in the majority of centres, although older anti-psychotics were used commonly in three centres.. The high doses of psychotropic drugs patients receive in some centres may be having little additional therapeutic effect and could increase their risk of side effects. The use of older anti-psychotics in some centres may be causing side effects that could be reduced by using newer anti-psychotics.

Atypical antipsychotics are being used increasingly in the management of mood disorders.. The objective of this study was to investigate the association between exposure to antipsychotic therapy and newly reported type 2 diabetes mellitus in patients with mood disorders.. Claims data for the period January 1996 through December 1997 were analyzed for patients with mood disorders in 2 large US health plans. Logistic regression models were used to determine the odds of reporting diabetes in patients exposed to risperidone, olanzapine, or high- or low-potency conventional antipsychotics compared with untreated patients, taking into account duration of treatment and dosage. Some of the covariates used in the models were concurrent use of antipsychotics, use of other psychotropic drugs, age, sex, and length of observation.. Based on the claims data, 849 patients were exposed to risperidone, 656 to olanzapine, 785 to high-potency conventional antipsychotics, and 302 to low-potency conventional antipsychotics; 2644 patients were untreated. The odds of newly reported type 2 diabetes in patients who received risperidone were not significantly different from those in untreated patients (12-month odds ratio [OR] = 1.024; 95% CI, 0.351-3.015). The odds in patients treated with high-potency conventional antipsychotics also did not differ significantly from those of untreated patients (12-month OR = 1.945; 95% CI, 0.794-4.786). Unlike patients who received risperidone or high-potency conventional antipsychotics, patients who received olanzapine (12-month OR = 4.289; 95% CI, 2.102-8.827) and low-potency conventional antipsychotics (12-month OR = 4.972; 95% CI, 1.967-12.612) had significantly higher odds for the development of type 2 diabetes compared with untreated patients.. These findings suggest that some antipsychotics may increase the risk for the development of type 2 diabetes in patients with mood disorders and that the effect may vary by drug. In contrast to olanzapine and low-potency conventional antipsychotics, risperidone and high-potency conventional antipsychotics were not associated with an increased risk for development of type 2 diabetes in this patient population.

A growing body of literature suggests that certain atypical antipsychotics, especially olanzapine and clozapine, may induce glucoregulatory dysfunction. We assessed the differences in risk of developing diabetes mellitus during treatment with olanzapine and risperidone by using patients treated with haloperidol and fluphenazine as control subjects in whom we would not expect to see an increased risk.. We conducted a retrospective analysis of the Veteran's Integrated Service Network 10 Veterans Affairs (VA) database. Data for patients receiving olanzapine, risperidone, haloperidol, or fluphenazine from January 1, 1997-December 31, 2000, were included. Diabetes was defined as any health system encounter associated with the International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis for diabetes (250.xx) or prescription for a hypoglycemic agent. Data of patients with markers for diabetes within 1 year before their index date, female patients, racial groups other than Caucasian or African-American, and patients receiving clozapine were not analyzed. We performed a Cox regression, with antipsychotic therapy as a time-dependent covariate. Other covariates considered for inclusion in the final model were number of days supply of antipsychotic drug, age, race, psychiatric diagnoses, substance abuse, lithium, valproic acid, and other typical or atypical antipsychotic agents.. Data for 5837 patients were analyzed. Overall rate of developing diabetes in the study population was 6.3% (368 of 5837 patients). Olanzapine therapy was associated with a significantly higher risk of development of diabetes compared with risperidone (hazard ratio [HR] 1.37, 95% confidence interval 1.06-1.76, p=0.016) while controlling for race, age, diagnosis, substance abuse, lithium, valproic acid, and other atypical antipsychotic agents. No differences in the rate of developing diabetes were detected between fluphenazine and risperidone (HR 1.11, p=0.69), or haloperidol and risperidone (HR 0.89, p=0.41).. Olanzapine was associated with a 37% (HR 1.37) increased risk of development of diabetes compared with risperidone in a VA population, even after adjusting for other factors associated with the development of diabetes and temporal exposure to study drug. Because of limitations associated with database research, prospective studies should be conducted to corroborate these findings.

The present study was designed to monitor the use of atypical antipsychotics in adults with intellectual disability and to evaluate the clinical effectiveness of these drugs. Twenty-one patients were commenced on an atypical antipsychotic: 12 on Olanzapine and nine on Risperidone. The ICD-10 diagnoses of the subjects were mild (13 cases) or moderate (8 cases) mental retardation, and psychiatric disorders (17 cases) with significant impairment of behaviour in 10 cases. Tolerability was good for 15 patients experiencing minimum or no side-effects, and medication was only stopped as a result of side-effects in one case. Clinical global outcome was rated as minimally improved or better for 16 cases. The present findings suggest that the atypical antipsychotics Olanzapine and Risperidone are well tolerated by patients with intellectual disability and psychiatric disorders, and are broadly effective against target symptoms.
