Effect of prolonged glyclazide treatment on blood glucose and plasma insulin responses in obese patients with maturity-onset diabetes

Abstract
The effect of prolonged treatment with glyclazide [GZ] [methyl-4-phenyl sulfonyl-l(perhydrocyclopenta(c) pyrrolyl-2)-3 urea] on blood glucose and plasma insulin responses to meals was studied in 8 obese patients with maturity-onset diabetes. Blood sampling was done 1 h after meals for 2 consecutive days, on days 10 and 90 of therapy. Lower blood glucose curves were achieved on both days 10 and 90 in all patients. Plasma insulin curves in response to meals were higher than control on both days 10 and 90. The long-term effect of glyclazide on blood glucose may be related to a persistent stimulation of insulin secretion rather than to a predominant extrapancreatic action.
