The diabetes warning has been rumored as a possibility since the findings from the JUPITER trial of rosuvastatin revealed an unexpected 27% increase in new onset diabetes among patients randomized to the statin.That finding was especially perplexing because JUPITER was a study of statins in patients who had no history of cardiovascular disease, the so-called healthy patient trial. Moreover, based on the JUPITER results, the FDA approved rosuvastatin for primary prevention.The FDA said hyperglycemia was also observed among patients treated with 40-mg atorvastatin in a substudy of PROVE-IT TIMI 22, and a meta-analysis of data from 13 statin trials “reported that statin therapy was associated with a 9% increased risk for incident diabetes.”
