Methylene blue causes vasoconstriction by inhibiting nitric oxide synthase. This is a potentially dangerous way to increase blood pressure, because it could potentially impair microvascular perfusion. Vasoconstriction is the narrowing of the blood vessels resulting from contraction of the muscular wall of the vessels, in particular the large arteries and small arterioles. The process is the opposite of vasodilation, the widening of blood vessels. The process is particularly important in controlling hemorrhage and reducing acute blood loss. When blood vessels constrict, the flow of blood is r…
