They concluded that with the exception of ziprasidone, all medications have been associated with weight gain; however aripiprazole was not included in this review. Jin and colleagues reviewed studies on the effect of atypical antipsychotics (clozapine, risperidone, olanzapine, quetiapine, ziprasidone and aripiprazole) on glucose dysregulation [Jin et al. 2004]. They included four extensive case buy Kinase Inhibitor Library series and summaries, 13 epidemiological studies from prescription and drug safety monitoring databases and 10 clinical studies on glucose intolerance

Inhibitors,research,lifescience,medical and atypical antipsychotics. Despite individual differences noted among various antipsychotics, they noted that patients Inhibitors,research,lifescience,medical with known risk factors for type II diabetes mellitus, such as ethnicity, first-degree family history of diabetes mellitus and baseline obesity, appear to be at increased risk for the development of glucose dysregulation during treatment. Meyer and Koro reviewed 48 studies and focused on the effects of FGAs and SGAs on serum lipids [Meyer and Koro, 2004]. They stated that high-potency conventional antipsychotics (haloperidol) and some atypicals (ziprasidone, risperidone and aripiprazole)

are associated with lower risk of dyslipidaemia, whilst low-potency conventional Inhibitors,research,lifescience,medical antipsychotics (chlorpromazine, thioridazine) and some other atypicals (quetiapine, olanzapine and clozapine) are related to higher risk of dyslipidaemia. Newcomer, Inhibitors,research,lifescience,medical in a massive and comprehensive literature review, gathered data from more than 200 studies on the metabolic effects of atypical antipsychotics, with special focus on weight gain and glucose and lipid dysregulation [Newcomer, 2005]. He extensively discussed eight antipsychotic medications, specifically clozapine,

Inhibitors,research,lifescience,medical olanzapine, risperidone, quetiapine, zotepine, amisulpride, ziprasidone and aripiprazole, and provided a detailed account of the metabolic profile of each. Clozapine and olanzapine were associated with the highest risk for causing clinically significant weight gain; risperidone, quetiapine, amisulpiride and zotepine a moderate Rutecarpine risk; ziprasidone and aripiprazole a lower risk. He also noted that this ranking reflected the relative risk for insulin resistance, dyslipidaemia and hyperglycaemia. In a systematic review and meta-analysis Smith and colleagues compared FGAs and SGAs with regards to their risk for type II diabetes mellitus [Smith et al. 2008]. The atypical antipsychotics included in this review (clozapine, olanzapine, risperidone and quetiapine) appeared to have a small increased risk only for development of diabetes compared with typical antipsychotics.
