Arteriolar vasodilators are substances or medications that preferentially dilate arterioles. When used on people with certain heart conditions, it causes a phenomenon known as the cardiac steal syndrome. Arteriolar vasodilators increase intracapillary pressure, which causes fluid to enter the tissues, leading to vasodilatory edema.
Arteriolar vasodilators include:
hydralazine
minoxidil
nitroprusside
