Association of hyperinsulinemia with chlorpropamide toxicity.
Clinical and metabolic features of chlorpropamide toxicity are described in two patients with diabetes mellitus and accidental chlorpropamide overdosage. Elevated serum insulin levels were found during hypoglycemia in both patients. The world's literature was reviewed for other cases of chlorpropamide toxicity in which insulin levels have been measured during hypoglycemia. A consistent feature of chlorpropamide toxicity is hyperinsulinemia. It is concluded that stimulation of the pancreatic beta cells during chlorpropamide toxicity leads to hyperinsulinemia and hypoglycemia.
