Angiotensin is a peptide hormone that causes vasoconstriction and an increase in blood pressure. It is part of the renin–angiotensin system, which regulates blood pressure. Angiotensin also stimulates the release of aldosterone from the adrenal cortex to promote sodium retention by the kidneys. An oligopeptide, angiotensin is a hormone and a ...
Angiotensin II (Ang II) is a medication that is used to treat hypotension resulting from septic shock or other distributive shock. It is a synthetic vasoconstrictor peptide that is identical to human hormone angiotensin II [ 3 ] and is marketed under the brand name Giapreza .
Flowchart showing the clinical effects of RAAS activity and the sites of action of ACE inhibitors and angiotensin receptor blockers. ACE inhibitors of angiotensin-converting enzyme inhibitors are often used to reduce the formation of the more potent angiotensin II. Captopril is an example of an ACE inhibitor.
Losartan, the first ARB. Angiotensin II receptor blockers (ARBs), formally angiotensin II receptor type 1 (AT 1) antagonists, [1] also known as angiotensin receptor blockers, [2] [3] angiotensin II receptor antagonists, or AT 1 receptor antagonists, are a group of pharmaceuticals that bind to and inhibit the angiotensin II receptor type 1 (AT 1) and thereby block the arteriolar contraction and ...
The angiotensin receptor is activated by the vasoconstricting peptide angiotensin II.The activated receptor in turn couples to G q/11 and G i/o and thus activates phospholipase C and increases the cytosolic Ca 2+ concentrations, which in turn triggers cellular responses such as stimulation of protein kinase C.
Angiotensin II receptor blockers (ARBs) work by inhibiting the action of angiotensin II on, specifically AT1 receptors to prevent the vasoconstrictor effects of this receptor and block the peripheral sympathetic activity.

Angiotensin-converting enzyme (EC 3.4.15.1), or ACE, is a central component of the renin–angiotensin system (RAS), which controls blood pressure by regulating the volume of fluids in the body. It converts the hormone angiotensin I to the active vasoconstrictor angiotensin II. Therefore, ACE indirectly increases blood pressure by causing blood ...
Angiotensin II receptor type 1 (AT1) is a G q/11-coupled G protein-coupled receptor (GPCR) and the best characterized angiotensin receptor. It is encoded in humans by the AGTR1 gene. AT1 has vasopressor effects and regulates aldosterone secretion. It is an important effector controlling blood pressure and volume in the cardiovascular system.
