Effect of Low (7.5 mg/day), Standard (15 mg/ day) and High (30 mg/day) Dose Pioglitazone Therapy on Glycemic Control and Weight Gain in Recently-Diagnosed Type 2 Diabetes Patients

Objective: To study the effect of different daily doses of pioglitazone on glycemic control and weight gain in newly-diagnosed type 2 diabetes mellitus (DM) patients. Research Design and Methods: Chart reviews were performed of recently-diagnosed (<24 months) type 2 DM patients receiving oral therapy including pioglitazone. Patients were excluded if they had heart disease, liver dysfunction or renal insufficiency; or were being treated with insulin or the incretin drugs. Patients had received 7.5 mg/day (Group A), 15 mg/day (Group B) or 30 mg/day (Group C) of pioglitazone. Characteristics including demographics, weight, body mass index and glycated hemoglobin (HbA1c) were recorded at baseline and at six months.
