So the issue will be if sodium causes vasodilation or vasocontriction, which will depend on receptors and ion channel balance between cells and plasma in the circulatory system. I don't recall immediately. Thinking...

OK- No, it's not used as a vasoconstrictor. Because despite sodium depletion, blood pressure is maintained, via vasoconstriction.
