It is not about dreams. DREAM stands for Diabetes Reduction Assessment Medication. Two drugs were tested: Altace (ramipril) and Avandia (rosiglitazone). Both drugs lowered blood sugar. But Altace did not prevent people with heart problems from developing diabetes. Avandia did delay the onset of diabetes in high risk patients on a dosage of 8mg a day for 3 years. However, Avandia brought on weight gain and edema which increased heart failure. Lifestyle changes (diet and exercise) are still best to prevent or delay diabetes.
