olanzapine and Coronary-Disease

Dyslipidemia is an increasing problem in most industrialized societies and is a risk factor for coronary heart disease (CHD). Imbalances in individual lipid components, including total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, and serum triglycerides, have each been shown to contribute to this increased risk. Certain psychiatric patient populations, such as those afflicted with schizophrenia, are of particular concern. Psychiatric patients with schizophrenia are naturally at increased risk for dyslipidemia and obesity, in part due to poor diet and sedentary lifestyle, but these conditions can be exacerbated by some antipsychotic medications. Clozapine and olanzapine, for example, appear to be associated with hyperlipidemia, which may be associated with changes in body weight. Other, newer antipsychotic agents may exhibit less liability for weight gain and the development of dyslipidemia. This review is intended to briefly highlight the association between dyslipidemia and cardiovascular disease, the changes in serum lipids associated with some antipsychotic agents, and how these changes in serum lipids affect the monitoring of schizophrenia patients.

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.

To assess the cost-effectiveness of aripiprazole versus olanzapine in the treatment of patients with schizophrenia or bipolar disorder in Sweden with focus on the metabolic impact of the treatments.. A Markov health-state transition model was developed. The risks of developing metabolic syndrome after one year of treatment with aripiprazole or olanzapine were derived from a pooled analysis of three randomised clinical trials. The subsequent risks of developing diabetes or coronary heart disease were based on previously published risk models. A societal perspective was applied, adopting a lifetime horizon. Univariate and probabilistic sensitivity analyses were conducted.. Treatment with aripiprazole dominates over olanzapine in both schizophrenia and bipolar disorder. In schizophrenia, quality-adjusted life-years (QALYs) gained were 0.08 and cost savings Swedish kronor (SEK) 30,570 (USD 4000); in bipolar disorder, QALYs gained were 0.09 and cost savings SEK 28,450 (USD 3720). In probabilistic sensitivity analyses, aripiprazole resulted in a dominant outcome in 84% of cases in schizophrenia and in 77% of cases in bipolar syndrome.. The significantly lower risk of developing metabolic syndrome observed with aripiprazole compared with olanzapine is associated with less risk of diabetes and cardiovascular morbidity and mortality that translates into lower overall treatment cost and improved quality of life over time.

Olanzapine is an antipsychotic drug that has been on the market since 1996. Olanzapine-related deaths are very rare; the literature reports only one. However, in a recent 5-month period one medical examiner's office found two such cases that are reported in this paper. One is a suicide and the other is not. The toxicologic and anatomic findings for each are described. Blood olanzapine concentrations ranged from 0.237 microg/ml for one to 0.675 microg/ml for the other. Gastric content concentrations also exhibited a wide range, varying from 0.197 microg/ml to 17.400 microg/ml for the other. Distribution studies of the liver, kidney, and brain produced nondetectable concentrations for the drug. There were no consistent pathologic anatomic findings for cause of death except for moderate coronary atherosclerosis in the nonsuicide case. Both deaths were attributed to olanzapine toxicity.
