Toxicology and overdose of atypical antipsychotic medications in children: does newer necessarily mean safer?
Atypical antipsychotic medications (second-generation antipsychotics) have been increasingly used in the treatment of a number of psychotic disorders since their introduction in 1988, with the newest medication introduced in 2002. Justification for their use includes claims of equal or improved antipsychotic activity over first-generation antipsychotics, increased tolerability, and decreased side effects. However, there are still significant adverse effects and toxicities with this class of medications. Toxicologic exposures and fatalities associated with atypical antipsychotics continue to increase in the United States, with 32,422 exposures and 72 deaths in 2003. There have also been Food and Drug Administration warnings in the past year about how some atypical antipsychotics have been marketed to minimize the potentially fatal risks and claiming superior safety to other atypical antipsychotics without adequate substantiation, indicating the toxicologic potential of these agents may be underestimated.. Continued research to evaluate adverse effects and tolerability of atypical antipsychotics compared with first-generation antipsychotics and each other is reviewed. This article also reviews the pharmacodynamics, pharmacokinetics, and drug interactions with these medications. New therapeutic monitoring recommendations for this class of medications have also been proposed. Finally, clinical toxicity in overdose and management are reviewed.. While new atypical antipsychotic medications may have a safer therapeutic and overdose profile than first-generation antipsychotic medications, many adverse and toxic effects still need to be considered in therapeutic monitoring and overdose management.

Medical burden in bipolar disorder: findings from the Clinical and Health Outcomes Initiative in Comparative Effectiveness for Bipolar Disorder study (Bipolar CHOICE).
Individuals with bipolar disorder have high rates of other medical comorbidity, which is associated with higher mortality rates and worse course of illness. The present study examined common predictors of medical comorbidity.. The Clinical and Health Outcomes Initiative in Comparative Effectiveness for Bipolar Disorder study (Bipolar CHOICE) enrolled 482 participants with bipolar I or bipolar II disorder in a six-month, randomized comparative effectiveness trial. Baseline assessments included current and lifetime DSM-IV-TR diagnoses, demographic information, psychiatric and medical history, severity of psychiatric symptoms, level of functioning, and a fasting blood draw. Medical comorbidities were categorized into two groups: cardiometabolic (e.g., diabetes, hyperlipidemia, and metabolic syndrome) and non-cardiovascular (e.g., seizures, asthma, and cancer). Additionally, we looked at comorbid substance use (e.g., smoking and drug dependence).. We found that 96.3% of participants had at least one other medical comorbidity. Older age predicted a greater likelihood of having a cardiometabolic condition. Early age of onset of bipolar symptoms was associated with a lower chance of having a cardiometabolic condition, but a greater chance of having other types of medical comorbidity. Additional predictors of other medical comorbidities in bipolar disorder included more time spent depressed, less time spent manic/hypomanic, and longer duration of illness. Medications associated with weight gain were associated with low high-density lipoprotein and abnormal triglycerides.. There appears to be a substantial medical burden associated with bipolar disorder, highlighting the need for collaborative care among psychiatric and general medical providers to address both psychiatric and other medical needs concomitantly in this group of patients.

Exploring genetic variations that may be associated with the direct effects of some antipsychotics on lipid levels.
The goal of this study was to select some genes that may serve as good candidates for future studies of the direct effects (not explained by obesity) of some antipsychotics on hyperlipidemia. A search for single-nucleotide polymorphisms (SNPs) that may be associated with these direct effects was conducted. From a published cross-sectional sample, 357 patients on antipsychotics were genotyped using a DNA microarray with 384 SNPs. A total of 165 patients were taking olanzapine, quetiapine or chlorpromazine which may directly cause hypertriglyceridemia or hypercholesterolemia. Another 192 patients taking other antipsychotics were controls. A two-stage statistical analysis that included loglinear and logistic models was developed to select SNPs blindly. In a third stage, physiological knowledge was used to select promising SNPs. Known physiological mechanisms were supported for 3 associations found in patients taking olanzapine, quetiapine or chlorpromazine [acetyl-coenzyme A carboxylase alpha SNP (rs4072032) in the hypertriglyceridemia model, and for the neuropeptide Y (rs1468271) and ACCbeta, (rs2241220) in the hypercholesterolemia model]. These genes may be promising candidates for studies of the direct effects of some antipsychotics on hyperlipidemia.

The effects of novel antipsychotics on glucose and lipid levels.
The novel antipsychotics are extensively used based on their favorable extrapyramidal side effect profiles. However, accumulating evidence suggests that these agents, particularly clozapine and olanzapine, have serious side effects of their own, including weight gain and elevated glucose and triglyceride levels. The goal of this study is to compare the effects of novel antipsychotics clozapine, olanzapine, risperidone, and quetiapine and typical antipsychotics haloperidol and fluphenazine on glucose and lipid levels.. The charts of 590 patients were retrospectively reviewed. Of those, 215 patients had adequate laboratory data for inclusion. Glucose and lipid level data from 2 1/2 years before and after initiation of the target antipsychotic were included. Covariates, including patients' age, the duration of antipsychotic treatment, other medications that may affect glucose or lipid levels, and the initial laboratory values, were controlled for in the analyses.. Glucose levels were increased from baseline for patients treated with clozapine, olanzapine, and haloperidol. There were statistically and clinically significant differences among the medications' effects on lipid profiles (p < .05). Those receiving clozapine and olanzapine demonstrated statistically significant increases in triglyceride levels compared with the other groups. Over one third of patients treated with any of the novel antipsychotics had clinically meaningful triglyceride elevations.. It has been shown that novel antipsychotics are associated with weight gain. This risk factor along with others, such as elevated glucose and triglyceride levels, compounds the risk for coronary artery disease. Routine monitoring of glucose and lipid levels during treatment with novel antipsychotics should be advocated.

Possible association of QTc interval prolongation with co-administration of quetiapine and lovastatin.
QTc interval prolongation can occur as a result of treatment with both conventional and novel antipsychotic medications and is of clinical concern because of its association with the potentially fatal ventricular arrhythmia, torsade de pointes.. One case is described in which a patient with schizophrenia, who was being treated for dyslipidemia, developed a prolonged QTc interval while taking quetiapine and lovastatin.. QTc returned to baseline when the lovastatin dose was reduced.. QTc prolongation associated with antipsychotic medication occurs in a dose-dependent manner. We therefore hypothesize that the addition of lovastatin caused an increase in plasma quetiapine levels through competitive inhibition of the cytochrome P(450) (CYP) isoenzyme 3A4. Our case highlights the potential for a drug interaction between quetiapine and lovastatin leading to QTc prolongation during the management of dysipidemia in patients with schizophrenia.

Novel antipsychotics and severe hyperlipidemia.
Newer atypical antipsychotics demonstrate superior effectiveness, with a diminished incidence of extrapyramidal side effects compared with older typical antipsychotics, but they have been associated with the development of obesity and new-onset diabetes. A small number of reports documenting modest hypertriglyceridemia related to newer antipsychotics have implicated fluperlapine, clozapine, and, most recently, olanzapine. This study summarizes the results of 14 cases of severe hypertriglyceridemia (>600 mg/dL) associated with olanzapine and quetiapine therapy occurring among inpatients at Oregon State Hospital, including 7 patients whose serum triglyceride levels exceeded 1,000 mg/ dL. Four of these patients also developed new-onset diabetes. Nine cases occurred during the first 8 months of treatment, with three cases identified within 3 months of commencing olanzapine or quetiapine therapy. Weight gain in olanzapine and quetiapine groups was modest (12.3 lb and 8.5 lb, respectively) and did not correlate with the severity of hypertriglyceridemia. Biochemical causes for severe hypertriglyceridemia associated with novel antipsychotics are unclear, but clinical monitoring of serum lipids must be added to the concerns about the metabolic consequences of therapy with certain newer antipsychotic agents.
