In a retrospective study we investigated the effects of altering treatment of type II diabetes mellitus from insulin to tolazamide on weight and blood pressure. In 17 patients, weight decreased from 136 +/- 6 to 131 +/- 6% of ideal body weight (P = .01). Even though weight loss occurred, mean systolic blood pressure increased from 133 +/- 3 mm Hg to 142 +/- 4 mm Hg (P = .025). There was no difference in diastolic blood pressure on the two treatments (79 +/- 3 v 78 +/- 4 mm Hg). In an additional 10 patients whose treatment was changed from tolazamide to insulin, mean systolic blood pressure decreased from 136 +/- 1 to 124 +/- 2 mm Hg (P < .01). In spite of the potential benefits of reversal of insulin resistance and weight reduction, altering therapy of type II diabetes mellitus from insulin to tolazamide may increase blood pressure, thereby increasing cardiovascular risk.
