Atypical antipsychotic AAP medications that have revolutionized the treatment of mental illness have become stigmatized by metabolic side effects, including obesity and diabetes. It remains controversial whether the defects are treatment induced or disease related. Although the mechanisms underlying these metabolic defects are not understood, it is assumed that the initiating pathophysiology is weight gain, secondary to centrally mediated increases in appetite.

There are concerns that antipsychotics increase the risk of diabetes. This review will examine the latest epidemiological studies linking antipsychotics and diabetes, as well as the mechanisms underlying the association and the clinical implications to minimise the impact of antipsychotics on metabolic health. Although there is an increased risk of diabetes in people with first-episode psychosis, the prevalence increases rapidly after antipsychotics are started. Antipsychotics likely increase the risk of diabetes through weight gain and directly by adversely affecting insulin sensitivity and secretion. It is important to implement measures to prevent diabetes, to screen for diabetes to ensure prompt diagnosis and to provide effective diabetes care. Further research is needed to understand how antipsychotics cause diabetes and to improve the clinical management of diabetes in people with severe mental illness. Diabetes occurs at an earlier age and acute metabolic emergencies and diabetes complications have a greater impact in people with severe mental illness. The reasons underlying the increased rates of diabetes are multifactorial but there are concerns that antipsychotics play a role in the aetiology. This review will describe how these concerns emerged, the difficulties in determining causality followed by the evidence linking antipsychotics to the development of diabetes.

Antipsychotic drugs APDs represent a cornerstone in the treatment of schizophrenia and other psychoses. The effectiveness of the first generation typical APDs are hampered by so-called extrapyramidal side effects, and they have gradually been replaced by second atypical and third-generation APDs, with less extrapyramidal side effects and, in some cases, improved efficacy. However, the use of many of the current APDs has been limited due to their propensity to stimulate appetite, weight gain, and increased risk for developing type 2 diabetes and cardiovascular disease in this patient group. The mechanisms behind the appetite-stimulating effects of the various APDs are not fully elucidated, partly because their diverse receptor binding profiles may affect different downstream pathways. It is critical to identify the molecular mechanisms underlying drug-induced hyperphagia, both because this may lead to the development of new APDs, with lower appetite-stimulating effects but also because such insight may provide new knowledge about appetite regulation in general.

Weight gain remains a well recognized yet difficult to treat adverse effect of many anti-psychotic drugs including agents of the first and second generation. The weight gain liabilities of antipsychotic drugs are partly associated with their ability to increase appetite.

An increased risk of diabetes was found in one of the two aripiprazole studies, three of four clozapine studies, seven of nine olanzapine studies, five of nine risperidone studies, three of six quetiapine studies and both ziprasidone studies. Abstract Purpose of Review The prevalence of diabetes is 2—3-fold higher in people with severe mental illness than the general population. Finally, although the study was powered to detect significant differences in olanzapine-induced changes in postprandial insulin release based on pilot data from our own laboratory, it was not powered to detect aripiprazole-induced changes in postprandial metabolism. Again, the effects of these drugs on the risk of diabetes in people taking antipsychotics have not been studied but a meta-analysis of 12 studies involving people treated with antipsychotics showed that metformin lead to a mean 3. The STRIDE weight loss and lifestyle intervention for individuals taking antipsychotic medications: a randomized trial. As well as the adverse effect on glucose and body weight, antipsychotics also worsen the lipid profile and so it may be expected that the incidence of macrovascular disease would differ between antipsychotics. No significant differences were found on any of the variables illustrated in these figures. Answer 1: Four. Olanzapine has been shown to be a high-affinity muscarinic receptor antagonist 40 and in vitro can block acetylcholine binding to muscarinic receptors on the pancreatic islet, thereby inhibiting insulin release However, within the short timeframe of this study, it is unlikely that small increases in visceral or hepatic fat would have been detected by dual-energy X-ray absorptiometry. The primary side effect of olanzapine was drowsiness. Furthermore, olanzapine was associated with a significantly greater change in glucose than ziprasidone 0. SI was calculated as the change in glucose disposal and dividing by the change in insulin and multiplying by glucose at steady state. Trade Name.

Although no effects on body weight were seen in one of the two trials of exenatide [ 62 ], the other showed a mean weight loss of 5.

Finally, although the study was powered to detect significant differences in olanzapine-induced changes in postprandial insulin release based on pilot data from our own laboratory, it was not powered to detect aripiprazole-induced changes in postprandial metabolism. Plasma enrichment of [1- 13 C]glucose and [6,6, 2 H 2 ]glucose was measured using gas chromatography—mass spectrometry at Metabolic Solutions Nashua, NH to simultaneously monitor the C 1—2 and C 3—6 fragments as well as the labeled glucose.
