NCIt definition : A benzothiadiazine derivate with antihypertensive and hyperglycemic activities. Diazoxide
increases membrane permeability to potassium ions in vascular smooth muscle, thereby
stabilizing the membrane action potential and preventing vascular smooth muscle contraction;
this results in peripheral vasodilatation and decreases in peripheral vascular resistance.
This agent also inhibits insulin release by interacting with ATP-sensitive potassium
channels of pancreatic islet beta-cells.;
