Angiotensin II

FDA approvedHeart and blood

How it works

The body's own angiotensin II: it binds AT1 receptors in artery walls and narrows them, rescuing blood pressure in shock.

What it's made of

8 amino acids (DRVYIHPF): the exact copy of the human hormone that narrows blood vessels. Nothing in it was changed. In the blood it lasts less than a minute.

What it's for

Prescribed for
Very low blood pressure in adults with septic shock or another distributive shock that does not respond to fluids or other vasopressors.
