High concentrations of alcohol constrict most blood vessels. This vasoconstriction depends on calcium ions and is inhibited by calcium channel blockers. Alcohol also acts to augment the vasoconstriction caused by catecholamines and vasopressin and inhibits endothelium-dependent vasodilation.
Is alcohol a vasoconstrictor or a vasodilator?
