This study examined the potential association between prescriptions of antipsychotics and antidiabetic medications. All people who purchased antipsychotics in Denmark during 1996 to 2005 were included (N = 345,937) and compared with a random sample of about 30% of the total Danish population (N = 1,426,488). Among the total population, incident diabetes subsequently developed in 50,379 individuals. Compared with unexposed individuals, treatment with first- (relative ratio [RR], 1.53; 95% confidence interval [CI], 1.49-1.56) as well as second-generation (RR, 1.32; 95% CI 1.22-1.42) antipsychotics was associated with increased risk for subsequent incident diabetes. The rate of incident diabetes varied substantially between individual second-generation antipsychotic drugs (olanzapine, risperidone, clozapine compared with unexposed individuals: low-to-moderate RR between 1.17 and 1.57; ziprasidone and sertindole: 2 or more times increased rate ratio; amisulpride, quetiapine, and aripiprazole: no significantly increased RR). For both first- and second-generation antipsychotics, the incidence of diabetes increased with the number of prescriptions. Additionally, the incidence of diabetes increased with the number of combined antipsychotic drugs….
