Type 2 diabetes patients who are uncontrolled (HbA1C between 7.5% and 9%), in spite of maximum dose of metformin and glibenclamide, are entered into the study after notification and their permission. First, patients’ demographic characteristics (age, gender, duration disease, height, weight, abdomen circumference) are determined. Next, base lab tests including, FBS, 2HPPBS, HbA1C, Chol, Tg, HDL are obtained. We start medication with low dose of bromocriptine (1.25 milligram) in bedtime. And, 1.25 milligram of the drug will be added every 3 days (in cases of no complication). We continue this until we reach 2.5 miligram of the drug twice a day. In first visit (1.5 month after starting), FBS, 2HPPBS will be measured. In second and third visit (3 months and 6 months), weight, FBS, 2HPPBS, HbA1C, Chol, Tg, HDL will be evaluated.
