Clinical experience with the oral antidiabetic compound, tolazamide

In clinical experience totalling 82 patient-years with the sulfonylurea tolazamide, satisfactory control of glycemia was obtained in 70% of diabetics. The preponderance of elderly and newly diagnosed diabetics in the group probably increased the percentage of successes, because when tolazamide was compared with tolbutamide in the same patients the frequency of clinical effectiveness was similar. The ratio of effectiveness by weight for tolbutamide/tolazamide was 6.6/1.0. No toxic effects were detected, side effects were minimal and there appeared to be little tendency to induce unwarranted hypoglycemia.
