Gliclazide in the treatment of obese non-insulin dependent diabetic patients.

: The clinical efficacy of gliclazide and its effect on plasma glucose, body weight and serum lipids was assessed in a 3 months open trial of 30 obese, Non-Insulin Dependent diabetes mellitus (NIDDM) patients who failed to respond to diet therapy alone. By day 20, the mean post prandial plasma glucose (PPG), and fasting plasma glucose (FPG) were significantly reduced from 276 +/- 13.5 to 195.8 +/- 13.9 mg % (p < 0.01) and 179 +/- 9.3 to 130.6 +/- 9.6 mg % (p < 0.01) respectively. This early glycaemic control was maintained, and by 3 months a further significant decrease occurred in PPG to 156.46 +/- 7.6 mg % (p < 0.01), and FPG to 106.9 +/- 3.8 mg % (p < 0.01). Mean glycosylated haemoglobin (HbA1c) was reduced from 10.3% to 7.7%. The drug had a favourable effect on serum lipids, significantly increasing high density lipoprotein fraction of cholesterol (HDL-C) (p < 0.034), and decreasing low density lipoprotein fraction of cholesterol (LDL-C) (p < 0.049). Mean body weight showed a significant reduction of 1.5 kg (p < 0.003). We conclude that gliclazide is an effective hypoglycaemic agent that ensures a rapid and sustained blood glucose control with a favourable effect on lipids and body weight in obese NIDDM patients.
