The efficacy and safety of gliclazide (Diamicron ®) were studied in 29 NIDDM patients (19 men and 10 women aged 25–68 years) who failed to improve with diet or with diet plus a sulfonylurea. All patients were overweight and had fasting blood glucose levels consistently above 150 mg/dl (8.24 mmol/l). After withdrawal of oral hypoglycemics where applicable, they received 40 mg Diamicron ® three times daily with meals. The dose was increased by 40–80 mg/day until optimum control was obtained or up to a maximum of 320 mg/day. Treatment lasted for 12 months. At the end of this period the mean fasting blood glucose level had fallen by 35% from 238 to 154 mg/dl and the mean 2-h postprandial blood glucose level had fallen by 28% from 237.7 to 195 mg/dl. The mean glycosylated hemoglobin level also fell by 30% from 10.10 to 7.02%, i.e. within the normal range. In addition, there was a 19% fall in triglyceride and a 10% fall in cholesterol levels, with no change in body weight. No changes were observed for serum insulin, C-peptide and glucagon levels, thyroid function tests, blood counts, liver and kidney function tests, uric acid, electrolytes, blood pressure or heart rate. No clinical or ECG abnormalities were observed in patients with or without cardiovascular disease. There were two presumptive hypoglycemic reactions, but these did not require treatment. Adverse effects were reported by 22 patients, including dizziness and light-headedness, diarrhea, nausea, palpitations and pruritus, but none required modification of Diamicron ® therapy. The results therefore show that Diamicron ® is safe, effective and well tolerated in suitably selected NIDDM patients.
