Abstract
OBJECTIVE: To review the pharmacoepidemiologic evidence for the link between exposure to atypical antipsychotics and the development of diabetes mellitus. DATA SOURCES: A MEDLINE search (1990–March 2003) was conducted. STUDY SELECTION AND DATA EXTRACTION: The search was limited to articles that described findings from analyses of large databases and used the words diabetes or hyperglycemia, and antipsychotic or clozapine or olanzapine or risperidone or quetiapine or ziprasidone or aripiprazole in the title or The odds ratio or relative risk, together with their corresponding confidence interval, was extracted. DATA SYNTHESIS: Results are conflicting, and this variability may be due to the different populations studied, different study designs, and the possibility of publication bias related to funding by the pharmaceutical industry. Nevertheless, an increased risk for diabetes mellitus appears to be present for patients receiving atypical antipsychotics. However, differential risk among the atypical antipsychotics is difficult to ascertain. CONCLUSIONS: Clinicians are urged to manage risk by regularly monitoring all patients receiving atypical antipsychotics for the emergence of diabetes mellitus. Future studies should carefully control for confounding variables such as age, diagnosis, change in weight, activity level, family history, and ethnicity.
