For use as an alternative to adrenaline as a localising agent, provided that local ischaemia is not essential.
Felypressin is a synthetic analog of lypressin or vasopressin with more vasoconstrictor activity than antidiuretic action. It is used primarily as a hemostatic. Felypressin is a non-catecholamine vasoconstrictor that is chemically related to vasopressin, the posterior pituitary hormone.
mechanism of action
Felypressin binds to the vasopressin receptor V1a. This causes contraction of the smooth muscle in the vascular bed, especially capillaries, small arterioles and venules.
