Changes in platelet aggregation caused by glyburide in diabetic patients

The effect of glyburide on platelet aggregation was investigated in 31 patients with maturity-onset diabetes. Platelet aggregation in platelet-rich plasma was measured before and one hour after the patients had ingested 5 mg of glyburide. The drug caused a significant decrease in platelet aggregation as determined by changes in the amplitude and slope of the curve.
